April 2023

[donsutherland1]

New York City has now surpassed its prior mark for most consecutive days without 1" or more snowfall by 30 days. That margin will very likely swell over coming months, as it appears no such snowfall is likely through the remainder of the 2022-2023 snow season.

Historical:

1936: An estimated F4 tornado cut a 15-mile path through Crisp County, GA. The hardest hit area was the town of Cordele, where 276 homes were destroyed in a five-block swath through the town. The storm was on a course that would have missed the center of town, but it made a left turn towards the end of its path. 23 people were killed and 500 injured. Total damage was $3 million.

 

1957: An F3 tornado tore through Dallas, TX. 10 people were killed, and 216 were injured. Total damage was $1.5 million. This tornado was among the most photographed and studied in history. Click HERE for more information.

1975 - The northeastern U.S. was in the grips of a severe storm which produced hurricane force winds along the coast, and two to three feet of snow in Maine and New Hampshire. Winds atop Mount Washington NH gusted to 140 mph. (David Ludlum)

1975 - The biggest snowstorm of record for so late in the season paralyzed Chicago, IL. Up to 20 inches of snow fell in extreme northeastern Illinois, and 10.9 inches of snow closed Chicago's O'Hare Airport. (The Weather Channel)

1982 - Severe thunderstorms spawned fifty-six tornadoes in the central U.S., including seventeen in the Red iver Region of Texas and Oklahoma. The tornadoes claimed thirty lives, and injured 383 other persons. A violent tornado near Messer OK left only the carpet tack strips on the slab of a house it destroyed, and carried a motel sign thirty miles. (The Weather Channel) (Storm Data)

1987 - Eleven cities in Florida reported record low temperatures for the date, including Tallahassee with a reading of 31 degrees. The low of 48 degrees at Key West smashed their previous record for the date by 13 degrees. (The National Weather Summary)

1988 - Thunderstorms produced up to nine inches of rain around New Orleans LA causing 18 million dollars damage. A tornado caused three million dollars damage at Slidell LA. (Storm Data) (The National Weather Summary)

1989 - Strong and gusty winds prevailed from California to Colorado and Wyoming. Winds gusted to 50 mph at Lancaster CA, and reached 85 mph at Berthoud Pass CO. Snow and high winds created blizzard conditions in the Colorado Rockies. (The National Weather Summary) (Storm Data)

1990 - Thunderstorms produced severe weather in North Carolina and Virginia during the afternoon and evening. Thunderstorms produced golf ball size hail, and spawned a tornado near Chester VA which caused half a million dollars damage. A storm system produced snow and gale force winds across northern Michigan, with 8.3 inches of snow reported at Marquette. Temperatures in the north central U.S. soared from morning lows in the 20s and 30s to afternoon highs in the 60s and 70s. Eight cities reported record highs for the date, including Havre MT with a reading of 77 degrees. (The National Weather Summary) (Storm Data)

2005 - Heavy rainfall in the Northeast produced flooding in parts of New York, New Jersey and Pennsylvania. Severe flooding along the Delaware River forced the evacuation of 6,000 residents in New Jersey and over 5,700 in Pennsylvania during the weekend of the 2nd-3rd. Around 3,200 homes in New Jersey were damaged, while one fatality was reported in New York (Associated Press).

2006 - Tornadoes and hail as big as softballs ripped through eight Midwestern states, killing at least 27 people, injuring scores and destroying hundreds of homes. In Tennessee, tornadoes killed 23 people, including an infant and a family of four. Severe thunderstorms, many producing tornadoes, also struck parts of Iowa, Kentucky, Arkansas, Missouri, Ohio, Illinois and Indiana. Strong wind was blamed or at least three deaths in Missouri. The weather service's Storm Prediction Center in Norman, Okla., said it had preliminary reports of 63 tornadoes. The worst damage occurred throughout the Tennessee Valley.

2015 - Late night severe storms produced 80 to 100 mph straight-line winds that caused extensive damage from Hutchinson to Newton and Wichita. An 89 mph wind gust was reported at the Kansas Aviation Museum located in southeast Wichita. (NWS, Wichita, KS)

The April Fools snow storm 1997 - April 1st

 

The April Fools Blizzard was the most significant winter storm of the 1996-1997 season. Snowfall totals up to that point were well below average in southern New England; only a handful of relatively minor snowfalls affected the region through the heart of the winter. Prior to the blizzard, Boston's seasonal snowfall stood at 26.5 inches, well under the average of around 40 inches.

The 25.4 inches of snow at Logan Airport in Boston was the fourth-biggest snowstorm in the city's history, behind the Blizzard of 2003 (27.6 inches), the well-known Blizzard of 1978 (27.1 inches), and the February 1969 Nor'Easter (26.3 inches). The storm was the biggest on record in the month of April and made April 1997 Boston's snowiest April on record.

Worcester received 33 inches of snow, which was the biggest snowstorm in the city's history until January, 2015.

This is why I don’t share the optimism many have for a Niño next winter. It’s totally possible I’m completely wrong and we have a kickass snow season finally, but I really feel like we’re going to struggle with warmth again. Domestic cold has been tough for us lately, we need that arctic pipeline in place. 
 

I haven’t touched on it much but several climatologists I follow have mentioned as far back as last year how they expect the next Niño to surge us globally over 1.5C, and now that’s even likelier due to the unfortunate, unexpected warmth forcing of Hunga Tonga. 
 

Prior to the recent papers that came out about that I tried to remain optimistic the ash and sulfur aerosol, though not as much as it should’ve been, would offset the warming caused by the water vapor flux. But the latest papers on this topic suggest that won’t be the case and will contribute to a strong warming push the next few years. 
 

Can’t extrapolate that down to regional conditions and yes we could still have a kickass winter despite with good teleconnections, but I’m concerned we’re going to be even torchier than normal. And if the N Atlantic is still on fire, perhaps even a Niño won’t temper the dreaded SER. 
 

Hoping to be 100% dead wrong. 
 

Warmth could be a factor again if this is another strong to super basin-wide event as outlined in the paper below. They theorize the expanding WPAC warm pool has lead to stronger El Niño’s since the 1970s. We only had 3 notably colder Modoki El Niño’s with 50”+ around NYC since the 1980s in 02-03, 09-10, and 14-15. Most other El Niño’s were near average  to above normal warmth in 82-83, 86-87, 87-88,  91-92, 94-95, 97-98, 04-05, 06-07 and 15-16. So 3 out of 12 notably colder with 50”+ snow. So that was the rarest group. Snowfall was much more variable among the remaining 9 years. 2 super El Niño years had memorable snowstorms in 82-83 and 15-16 in warm winters.  The 97-98 super was a disappointment with  all warmth an little snow. 86-87 and 04-05 El Niño’s had decent snows around the region with near normal temperatures. Odd years like 06-07 and 94-95 were milder without much snow.

Historical change of El Niño properties sheds light on future changes of extreme El Niño

 

 

49,207114

• • Significance

How the magnitude of El Niño will change is of great societal concern, yet it remains largely unknown. Here we show analysis of how changing El Niño properties, due to 20th century climate change, can shed light on changes to the intensity of El Niño in the future. Since the 1970s, El Niño has changed its origination from the eastern Pacific to the western Pacific, along with increased strong El Niño events due to a background warming in the western Pacific warm pool. This suggests the controlling factors that may lead to increased extreme El Niño events in the future. If the observed background changes continue under future anthropogenic forcing, more frequent extreme El Niño events will induce profound socioeconomic consequences.

Abstract

El Niño’s intensity change under anthropogenic warming is of great importance to society, yet current climate models’ projections remain largely uncertain. The current classification of El Niño does not distinguish the strong from the moderate El Niño events, making it difficult to project future change of El Niño’s intensity. Here we classify 33 El Niño events from 1901 to 2017 by cluster analysis of the onset and amplification processes, and the resultant 4 types of El Niño distinguish the strong from the moderate events and the onset from successive events. The 3 categories of El Niño onset exhibit distinct development mechanisms. We find El Niño onset regime has changed from eastern Pacific origin to western Pacific origin with more frequent occurrence of extreme events since the 1970s. This regime change is hypothesized to arise from a background warming in the western Pacific and the associated increased zonal and vertical sea-surface temperature (SST) gradients in the equatorial central Pacific, which reveals a controlling factor that could lead to increased extreme El Niño events in the future. The Coupled Model Intercomparison Project phase 5 (CMIP5) models’ projections demonstrate that both the frequency and intensity of the strong El Niño events will increase significantly if the projected central Pacific zonal SST gradients become enhanced. If the currently observed background changes continue under future anthropogenic forcing, more frequent strong El Niño events are anticipated. The models’ uncertainty in the projected equatorial zonal SST gradients, however, remains a major roadblock for faithful prediction of El Niño’s future changes.

Whatever happens next winter pretty much can't be any worse than this one unless we really get 0 snow instead of 2"

Yeah, we haven’t had 2 consecutive years under 5” before. Getting 0 is a challenge since even Philly, DC ,and Richmond haven’t been able to avoid a trace.

That late 90s period really was horrific lol (throw in 2001-02 too to cap it all off)....two consecutive seasons with 10 inches or less of snow and that's before 2001-02.

JFK had two straight below 10 inch snowfall seasons and 3 out of 4 in the early 90s.

Very volatile snowfall seasons since the 1990s. There were 6 top 10 snowiest and 8 least snowiest years. So doing seasonal snowfall forecasting has been nearly impossible. Very big swings between years. Much less variation in the 60s, 70s, and 80s.

and I believe that 95-96 total was actually over 70" because of the undermeasurement during the January 1996 blizzard (same with NYC).

Some of those years were downright shocking, 1988-89 and 1989-90 were the back to backs with less than 10 inches and it was really annoying in 1989-90 because we got off to a quick start with the Thanksgiving snowstorm and December was so cold.

I thought 91-92 was also below 10" but maybe not.  Or maybe it was 96-97?

Top 3 winters by far were 1995-96, 1960-61 and 2002-03

I take it 2009-10, 2010-11 and 2013-14, 2014-15 were the only 2 couplets that were back to back over 40"?

Are the longterm snowfall averages and 30 year snowfall means both under 24" at JFK, Chris?

Are the longterm snowfall averages and 30 year snowfall means both under 24" at JFK, Chris?

The 95-96 measurements were close to the surrounding areas.

it just seems weird to be the only places under 70 inches though and there weren't any snow to rain storms, do you believe there was widespread undermeasurement in the January 1996 blizzard too?

Also, didn't JFK measure 4.5" in the April snowstorm?  That would mean its total was more like 64-65 inches before April, which seems really low for 95-96.  How much did Oceanside measure in the January blizzard and in the April snowstorm, if you have those numbers, Chris?

long island certainly has, they had 8 tornadoes in one day in November-- that's unprecedented in ANY month!

 

I wonder if it has anything to do with our climate becoming more like the DC/MD/VA area in the last decade, I know tornadoes aren’t exactly uncommon around there

Historical:

1936: An estimated F4 tornado cut a 15-mile path through Crisp County, GA. The hardest hit area was the town of Cordele, where 276 homes were destroyed in a five-block swath through the town. The storm was on a course that would have missed the center of town, but it made a left turn towards the end of its path. 23 people were killed and 500 injured. Total damage was $3 million.

 

1957: An F3 tornado tore through Dallas, TX. 10 people were killed, and 216 were injured. Total damage was $1.5 million. This tornado was among the most photographed and studied in history. Click HERE for more information.

1975 - The northeastern U.S. was in the grips of a severe storm which produced hurricane force winds along the coast, and two to three feet of snow in Maine and New Hampshire. Winds atop Mount Washington NH gusted to 140 mph. (David Ludlum)

1975 - The biggest snowstorm of record for so late in the season paralyzed Chicago, IL. Up to 20 inches of snow fell in extreme northeastern Illinois, and 10.9 inches of snow closed Chicago's O'Hare Airport. (The Weather Channel)

1982 - Severe thunderstorms spawned fifty-six tornadoes in the central U.S., including seventeen in the Red iver Region of Texas and Oklahoma. The tornadoes claimed thirty lives, and injured 383 other persons. A violent tornado near Messer OK left only the carpet tack strips on the slab of a house it destroyed, and carried a motel sign thirty miles. (The Weather Channel) (Storm Data)

1987 - Eleven cities in Florida reported record low temperatures for the date, including Tallahassee with a reading of 31 degrees. The low of 48 degrees at Key West smashed their previous record for the date by 13 degrees. (The National Weather Summary)

1988 - Thunderstorms produced up to nine inches of rain around New Orleans LA causing 18 million dollars damage. A tornado caused three million dollars damage at Slidell LA. (Storm Data) (The National Weather Summary)

1989 - Strong and gusty winds prevailed from California to Colorado and Wyoming. Winds gusted to 50 mph at Lancaster CA, and reached 85 mph at Berthoud Pass CO. Snow and high winds created blizzard conditions in the Colorado Rockies. (The National Weather Summary) (Storm Data)

1990 - Thunderstorms produced severe weather in North Carolina and Virginia during the afternoon and evening. Thunderstorms produced golf ball size hail, and spawned a tornado near Chester VA which caused half a million dollars damage. A storm system produced snow and gale force winds across northern Michigan, with 8.3 inches of snow reported at Marquette. Temperatures in the north central U.S. soared from morning lows in the 20s and 30s to afternoon highs in the 60s and 70s. Eight cities reported record highs for the date, including Havre MT with a reading of 77 degrees. (The National Weather Summary) (Storm Data)

2005 - Heavy rainfall in the Northeast produced flooding in parts of New York, New Jersey and Pennsylvania. Severe flooding along the Delaware River forced the evacuation of 6,000 residents in New Jersey and over 5,700 in Pennsylvania during the weekend of the 2nd-3rd. Around 3,200 homes in New Jersey were damaged, while one fatality was reported in New York (Associated Press).

2006 - Tornadoes and hail as big as softballs ripped through eight Midwestern states, killing at least 27 people, injuring scores and destroying hundreds of homes. In Tennessee, tornadoes killed 23 people, including an infant and a family of four. Severe thunderstorms, many producing tornadoes, also struck parts of Iowa, Kentucky, Arkansas, Missouri, Ohio, Illinois and Indiana. Strong wind was blamed or at least three deaths in Missouri. The weather service's Storm Prediction Center in Norman, Okla., said it had preliminary reports of 63 tornadoes. The worst damage occurred throughout the Tennessee Valley.

2015 - Late night severe storms produced 80 to 100 mph straight-line winds that caused extensive damage from Hutchinson to Newton and Wichita. An 89 mph wind gust was reported at the Kansas Aviation Museum located in southeast Wichita. (NWS, Wichita, KS)

I can add some details on that 1975 storm, which you are welcome to use tomorrow. I was living about 100 miles north of Toronto (which had over 10" of snow overnight 2nd-3rd) and we got an incredible dump of about 28 inches, would say the first half was synoptic scale and the second half was lake enhanced in NW winds off Georgian Bay. That was a fairly typical amount north of Toronto. Then the winds howled at 40-50 mph for two days and eventually the snow was reshaped into alternating bare spots and eight foot drifts all over the open countryside outside of larger towns. Many hundreds of people were stranded on regional highways during the storm, and ended up taking shelter in small towns around Barrie in Simcoe County, it was almost a week before some of them could get moving again, as the roads became totally impassable and plows couldn't get past the first mile or two of drifts. Where I lived, I was unable to move any of the snow drifts in my driveway because the daily freeze-thaw cycle in strong April sunshine ended up freezing them solid like concrete road barriers. There was about two weeks of quite cold and sunny weather with lows well below 20F at night, and this mess slowly evaporated away into the dry air. May of 1975 turned very hot and it stayed quite dry most of the summer in that region. It was certainly a weather singularity and in marked contrast to the 1974 super-tornado outbreak on 3rd-4th, and the early season heat in April of 1976 and 1977. 

You'll see there were some quite cold days at NYC after the storm, that was in part due to the strong NW winds blowing down off the extensive snow covered land. We were not breaking 25F in the daytime for the first few days after the storm, and eventually we were running about 15 degrees below normal for the month (it later relaxed a bit but still finished quite low). At Midhurst ON which is about thirty miles southwest of where I was located, the mean temperature for the first two weeks of April was -3.6 C (about 26 F) and normal there would be around 40F. They recorded 19" of snow in the blizzard, and over a week later there was a low of 8F there on the 11th of April.

This morning's chill will be short-lived. Temperatures will turn much milder tomorrow.

Overall, the first week of April will likely turn out warmer than normal. As has been the case throughout the winter and early part of spring, the coldest air will remain confined largely to western and central North America. Some of the guidance now brings the cooler air into the East for the second week of April, but uncertainty still exists.

Historic experience with very low snowfall totals through February argues that a very snowy March or big snowstorm during March or April are unlikely. There were 16 winters that had less than 8" of snowfall through February in New York City. Just two (13%) had a 6" or greater snowstorm during March or April: 1889-1890: 6.0" on March 19th and 1991-1992: 6.2" on March 19th.

With just 2.3" snowfall through March 19, New York City is now extremely likely to finish the season with less than 10" of snow. Since 1869-70, all 10 winters with less than 8.5" of snow through March 19th wound up with less than 10" of seasonal snowfall. New York City is currently on a path that could culminate in its setting a new record for lowest seasonal snowfall.

The ENSO Region 1+2 anomaly was +2.0°C and the Region 3.4 anomaly was 0.0°C for the week centered around March 22. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +1.20°C and the ENSO Region 3.4 anomaly has averaged -0.17°C. Neutral ENSO conditions will likely prevail through at least mid-spring.

The SOI was -13.56 today.

The preliminary Arctic Oscillation (AO) was -0.225 today.

On March 31 the MJO was in Phase 5 at an amplitude of 0.437 (RMM). The March 30-adjusted amplitude was 0.502 (RMM).

Slowly working our way to "longest day"  -  about 79 days to go before we start slowly going the other way.  Not that I'm trying to rush anything.

Have to enjoy each season for what it offers.

It does appear that we've seen an uptick in tornadoes as of late but not sure. 

Here's a chart for counties served by the Mt Holly Forecast Office, recent uptick for sure especially for the immediate Philly metro area. Current with yesterday's 5 tornadoes.

We don’t know enough about this one yet for any analogs. 

so over the previous 47 yrs. back to 1975 there was 1 tornado recorded in NJ during the month of April, yesterday there were 4
