SACRUS Posted March 30, 2023 Share Posted March 30, 2023 Records: Highs: EWR: 86 (1998) NYC: 82 (1998) LGA: 79 (1998) Lows: EWR: 22 (1970) NYC: 16 (1887) LGA: 23 (1970) Historical: 1805: New York's City's Battery Park was strewn with 24-inch snow rollers, from a ferocious storm between the March 26th and March 28th. Snow rollers are natural snowballs that are formed when winds blow over a snow-covered surface. 1823 - A great Northeast storm with hurricane force winds raged from Pennsylvania to Maine. The storm was most severe over New Jersey with high tides, uprooted trees, and heavy snow inland. (David Ludlum) 1848: On six reported occasions, the water flow over the American Falls has been entirely blocked by ice and ceased to fall. But only once has this happened on the much larger Horseshoe Falls. 1899 - A storm which buried Ruby, CO, under 141 inches of snow came to an end. Ruby was an old abandoned mining town on the Elk Mountain Range in the Crested Butte area. (The Weather Channel) 1977 - Hartford, CT, hit 87 degrees to establish a record for the month of March. (The Weather Channel) 1987 - A storm spread heavy snow across the Ohio Valley and Lower Great Lakes Region. Cleveland OH received sixteen inches of snow in 24 hours, their second highest total of record. Winds gusting to 50 mph created 8 to 12 foot waves on Lake Huron. The storm also ushered unseasonably cold air into the south central and southeastern U.S., with nearly one hundred record lows reported in three days. (The National Weather Summary) (Storm Data) 1988 - A winter-like storm developed in the Central Rockies. Snowfall totals in Utah ranged up to 15 inches at the Brian Head Ski Resort, and winds in Arizona gusted to 59 mph at Show Low. (The National Weather Summary) (Storm Data) 1989 - Thunderstorms developing along and ahead of a slow moving cold front produced large hail and damaging winds at more than fifty locations across the southeast quarter of the nation, and spawned a tornado which injured eleven persons at Northhampton NC. (The National Weather Summary) (Storm Data) 1990 - Low pressure produced heavy snow in central Maine and northern New Hampshire, with up to eight inches reported in Maine. A slow moving Pacific storm system produced 18 to 36 inches of snow in the southwestern mountains of Colorado in three days. Heavier snowfall totals included 31 inches at Wolf Creek Pass and 27 inches at the Monarch Ski Area.

donsutherland1 Posted March 30, 2023 Share Posted March 30, 2023 This morning, the temperature fell to 31° in Central Park. That will very likely be New York city's last freeze of 2022-2023. The last freeze of 2021-2022 also occurred on March 30th. There are two cases where the last freeze occurred on the same date in two consecutive years: April 3rd in 1906 and 1907 and April 10th in 1974 and 1975. The normal last freeze is March 29th (1991-2020 baseline). The cold will be short-lived. The weather will rapidly turn milder starting tomorrow. Temperatures will likely surge well into the 50s in New York City and into the lower 60s in parts of New Jersey and southeastern Pennsylvania. Saturday will likely start April off on a much warmer than normal note as showers give way to some sunshine. Another cold front could bring showers and thundershowers to the region late in the day. There is some chance that there could be a squall line with strong to perhaps severe thunderstorms. Highs will top out in the upper 60s and lower 70s in the northern Mid-Atlantic region. 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 considerable uncertainty exists. In terms of the month as a whole, it is somewhat more likely than not that April will wind up on the warm side of normal. 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 -0.72 today. The preliminary Arctic Oscillation (AO) was +1.152 today. On March 28 the MJO was in Phase 3 at an amplitude of 1.033 (RMM). The March 27-adjusted amplitude was 1.039 (RMM). Based on sensitivity analysis applied to the latest guidance, there is an implied near 100% probability that New York City will have a warmer than normal March (1991-2020 normal). March will likely finish with a mean temperature near 44.6° (1.8° above normal normal). 2 2 Link to comment Share on other sites More sharing options...

MGJ is at 364' and was 19 while SWF, 7 miles away as the crow flies at an elevation of 492' was 25. I realize this isn't exactly what you said above but I always find these nuances and microclimates interesting. I've seen much more noticeable differences between Montgomery and Stewart during inversions in the past. 1 Link to comment Share on other sites More sharing options...

SACRUS Posted March 31, 2023 Share Posted March 31, 2023 Records: Highs: EWR: 85 (1998) NYC: 86 (1998) LGA; 82 (1998( Lows: EWR: 24 (1964) NYC; 14 (1923) LGA: 24 (1964) Historical: 1890 - Saint Louis, MO, received 20 inches of snow in 24 hours. It was the worst snowstorm of record for the St Louis. (David Ludlum) 1942: 107 inches of rain fell during the month at Puu Kukui at Maui, Hawaii to set the U.S. record for rainfall in one month. The same place also holds the annual rainfall record for the United States with 578 inches in 1950. 1954 - The temperature at Rio Grande City, TX, hit 108 degrees, which for thirty years was a U.S. record for the month of March. (The Weather Channel) 1962 - A tornado struck the town of Milton, FL, killing 17 persons and injuring 100 others. It was the worst tornado disaster in Florida history. (David Ludlum) 1973 - A devastating tornado took a nearly continuous 75 mile path through north central Georgia causing more than 113 million dollars damage, the highest total of record for a natural disaster in the state. (The Weather Channel) 1987 - March went out like a lion in the northeastern U.S. A slow moving storm produced heavy snow in the Lower Great Lakes Region, and heavy rain in New England. Heavy rain and melting snow caused catastrophic flooding along rivers and streams in Maine and New Hampshire. Strong southerly winds ahead of the storm gusted to 62 mph at New York City, and reached 87 mph at Milton MA. (The National Weather Summary) (Storm Data) 1988 - March went out like a lion in eastern Colorado. A winter-like storm produced 42 inches of snow at Lake Isabel, including 20 inches in six hours. Fort Collins reported 15 inches of snow in 24 hours. Winds gusted to 80 mph at Centerville UT. Albuquerque NM received 14 inches of snow. (The National Weather Summary) (Storm Data) 1989 - Afternoon thunderstorms produced severe weather from North Carolina to Pennsylvania. Thunderstorm winds gusted to 76 mph at Cape Henry VA. While squalls blanketed northwest Pennsylvania with up to 9 inches of snow, thunderstorms in eastern Pennsylvania produced golf ball size hail at Avondale. (Storm Data) (The National Weather Summary) 1990 - The month of March went out just as it came in, like a lamb. Marquette MI, which started the month with a record high of 52 degrees, equalled their record for the date with a reading of 62 degrees. (The National Weather Summary) 2010 - Jacksonville, Florida's, record streak of days with high temperatures below 80 degrees comes to an end at 105 days. It was also Jacksonville's first 80 degree reading of the year. The previous latest first 80 degree day was on March 14, 1978. Link to comment Share on other sites More sharing options...

That 9 degree gap has to be one of the largest I've ever seen. JFK was much closer to FRG. It was actually colder this morning than it was the previous morning. This goes to show how artificial the climate of NYC (and LGA) really is, while JFK and EWR have much more natural temperatures ranges. Link to comment Share on other sites More sharing options...
