Low of 30 and now already up to 42.

 

Normal split in EWR is 60/42 and the next 7 days looks to be much above normal - peaking Thu (4/13) - Sat (4/15) with mainly dry conditions.  Trough pushes into the east by next Monday (4/17) with some rains and much cooler period 4/18 - 4/21.  We'll see if its more back and forth bias warm as it looks to have ridge rebild east by the 21/22nd.

Historical:

1894 - A heavy late season snow blanketed parts of the northeastern U.S. Heavier snowfall totals included 31.5 inches at Salem Corners PA, 30 inches at LeRoy NY, 26 inches at York PA, 14 inches at Waterbury CT, and 9 inches at Providence RI. (The Weather Channel)

1935 - Severe dust storms across Iowa and Kansas closed schools and highways. Dodge City KS experienced its worst dust storm of record, with dense dust reported from the morning of the 9th until after sunset on the 11th. The sky was almost as dark as night at times during the daylight hours. The thick dust suspended traffic on highways and railroads, and also suspended most business in town. (The Weather Channel)

1979 - A massive tornado smashed into Wichita Falls, TX, killing 43 persons and causing 300 million dollars damage. Another tornado struck Vernon TX killing eleven persons. (David Ludlum) (Storm Data)

1987 - Blustery northwest winds prevailed across the Northern Plains Region. Winds in Wyoming gusted to 65 mph. Temperatures in North Dakota were only in the 20s and 30s, following afternoon highs in the 70s the previous day. (The National Weather Summary)

1988 - Unseasonably warm weather prevailed in the western U.S. Eleven cities reported new record high temperatures for the date, including Bakersfield CA with a reading of 95 degrees, their warmest for so early in the season. Pocatello ID warmed from a record low of 19 above to an afternoon high of 63 degrees. (The National Weather Summary)

1989 - Strong northerly winds, gusting to 53 mph at Albuquerque, NM, ushered cold arctic air into the south central U.S. The temperature at Albuquerque plunged from 82 degrees to 29 degrees overnight. Thirty-three cities in the central U.S. reported record low temperatures for the date, including Goodland KS with a reading of 4 degrees above zero. (The National Weather Summary)

1990 - Thunderstorms produced severe weather from the Central Gulf Coast Region to western sections of the Carolinas during the afternoon and evening. Evening thunderstorms over western South Carolina produced wind gusts to 98 mph which injured four persons at Holly Springs, and wind gusts to 100 mph which injured one person and caused half a million dollars damage north of Dacusville. (The National Weather Summary) (Storm Data)

2005 - Heavy snow affected the Colorado Rockies during April 10-11, as up to 30 inches of snow affected the mountains around Denver. In the Denver metro area, 10-15 inches of snow accumulated.

Since we have a westerly flow later in the week and not S, it can be an overperformer. We roast when we get these westerly downslope air masses.

[Picard]

Wide temperature spreads today.  My low is 31, with a high of 70.  Several other stations recorded 40 degrees+ min/max variation.

The state low shows 21 early this morning at a station just west of Toms River.  Almost doesn't seem right, but maybe it is.  It must be a wide open flat area to radiate like that.

I expect a possibility of red-flag warnings coming this week, especially if the breeze kicks up a bit, and also the drought monitor to expand the yellow color in our area.

[donsutherland1]

Temperatures rose into the middle and upper 60s today. Even warmer weather lies ahead.

In coming days, the calendar will seemingly be turned ahead closer to summer, as an impressive warmup evolves. Temperatures could reach the middle 80s by late in the week, possibly challenging or breaking some record highs on Friday.

Overall, warmth appears likely to define April in much of the East. If the long-range guidance is accurate the first three weeks of the month could put April 2023 on a trajectory that could rank it among the 10 warmest Aprils on record in the northern Middle Atlantic region. Afterward, the latest EPS weeklies suggest that the month could finish with near normal readings.

The most recent April case to rank among the 10 warmest was:

Boston: 51.7°, 2019 (5th warmest)
Bridgeport: 54.0°, 2017 (1st warmest)
Islip: 51.9°, 2019 (6th warmest)
New Haven: 50.8°, 2022 (6th warmest)
New York City-Central Park: 57.2°, 2017 (2nd warmest)
New York City-JFK Airport: 55.1°, 2017 (2nd warmest)
New York City-LaGuardia Airport: 57.6°, 2017 (2nd warmest)
Newark: 57.2°, 2017 (4th warmest)
Philadelphia: 59.0°, 2019 (3rd warmest)
Poughkeepsie: 53.0°, 2017 (3rd warmest)
White Plains: 53.9°, 2017 (2nd warmest)

The ENSO Region 1+2 anomaly was +2.7°C and the Region 3.4 anomaly was 0.0°C for the week centered around April 5. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +1.77°C and the ENSO Region 3.4 anomaly has averaged -0.03°C. Neutral ENSO conditions will likely prevail through at least mid-spring. El Niño conditions will likely develop during the summer.

The SOI was +5.55 today.

The preliminary Arctic Oscillation (AO) was +1.066 today.

On April 8 the MJO was in Phase 6 at an amplitude of 1.470 (RMM). The April 7-adjusted amplitude was 1.205 (RMM).

Based on sensitivity analysis applied to the latest guidance, there is an implied 87% probability that New York City will have a warmer than normal April (1991-2020 normal). April will likely finish with a mean temperature near 57.3° (3.6° above normal). That would rank as the second warmest April on record.

The next 8 days are averaging    67degs.(58/76) or +13.

Month to date is    53.2[+3.4].        Should be     59.4[+7.7] by the 19th.

Reached 55 here yesterday---all afternoon.

Today:  68-73, wind w., p. sunny, 61 tomorrow AM.

49*(59%RH) here at 7am{was 48 at 6am}.     50* at 8am.      52* at 9am.        60* at Noon.     62* at 12:30pm.       70* at 3pm---but sun is filtered out now.    Reached  71*(33%RH) at 3:30pm.      67* at 7pm.

[SACRUS]

Low of 41 and up to 55 already. Recent dryness and time of year should put up some overperformers with mainly sunny conditions 4/11 - 4/15.  Weekend is warm but could be cloudy ahead of cooldown next week April 17 - 20.  Back and forth warm - cool down (bias warm overall) last 10 days of the month.

1965 - Severe thunderstorms in the Upper Midwest spawned fifty-one tornadoes killing 256 persons and causing more than 200 million dollars damage. Indiana, Ohio and Michigan were hardest hit in the "Palm Sunday Tornado Outbreak". (David Ludlum)

 

1965: Severe thunderstorms in the Upper Midwest spawned fifty-one tornadoes killing over 250 people and causing more than 200 million dollars damage. Indiana, Ohio and Michigan were hardest hit in the "Palm Sunday Tornado Outbreak". Although no F5's were officially reported, at least 22 were rated as F3 or F4. This is the third deadliest day for tornadoes on record, behind the Super Outbreak of 4/3/1974, and the outbreak that included the Tri-State Tornado of 3/18/1925. Dr. Ted Fujita discovered suction vortices during the Palm Sunday tornado outbreak. It had been believed the reason why tornadoes could hit one house and leave another across the street completely unscathed was because the whole tornado would "jump" from one house to another. However, the actual reason is because most of the destruction is caused by suction vortices: small, intense mini-tornadoes within the main tornado. 

1987 - Ten days of flooding in the northeastern U.S. finally came to an end. Damage from flooding due to rain and snow melt ran into the billions of dollars. The collapse of the New York State Thruway Bridge over Schoharie Creek claimed ten lives. (Storm Data)

1988 - Sixteen cities in the western U.S., nine in California, reported new record high temperatures for the date. Afternoon highs of 95 degrees at Sacramento CA and 96 degrees at Bakersfield CA were the warmest of record for so early in the season. (The National Weather Summary)

1989 - Forty-four cities in the south central and eastern U.S. reported new record low temperatures for the date. Lows of 25 degrees at Conway AR, 29 degrees at Dallas/Fort Worth TX, and 22 degrees at Ozark AR, were April records. Lows of 26 degrees at Hot Springs AR and 31 degrees at Shreveport LA equalled April records. (The National Weather Summary)

1990 - While showers produced heavy rain over much of the northeastern U.S., heavy snow blanketed northern Maine, with 13 inches reported at Telos Lake. Strong southwesterly winds accompanying the rain and snow gusted to 68 mph at the Blue Hill Observatory in Massachusetts. Rainfall totals of 1.04 inch at Pittsburgh PA and 1.52 inch at Buffalo NY on the 10th were records for the date. (The National Weather Summary) (Storm Data)

 

2012: The deluge began around 3:30 a.m. Over the next few hours, fast-moving hailstones pummeled the area north of Amarillo, Tex., which had lately been sitting in dust due to a lack of precipitation, according to the news organization. The hail mixed with melting hail turning the dust to mud and the mix create four-foot high mounds that shut down a major highway for the next 18 hours.

It's insane how fast this pattern is switching to a strong El Nino

Yes except for that brief cold shot around May 8-10 with snow in parts of the northeast U.S. (trace at NYC 9th). 

Despite that it was very warm in May also, otherwise. 

That was very memorable, the only time I've seen snow here in May was in 2020.  So we went from record cold to early heat to latest snowfall to historic heat (in July 1977 we had our hottest week on record)-- that's MY kind of weather!  And of course the winter after that was historic also.

was the state low at an official airport measuring station?

How close was the low at MJX to 21?

Thanks!

Looking for FOK data too, usually FOK and MJX and MVY compete for the lowest temps on radiational cooling nights

I wonder if Providence had 9 inches, how much NYC/Long Island had?  We should have seen some accumulation down here from that too.

Yeah but we can't count on that. A 50 to 100 mile shift south and its a miss for most of the area. That was like a nonexistent winter for new England and even NY north of 84

I think that's why there's an advantage being farther south.

Three of the four of the 20"+ snowfalls that I have seen here have occured in moderate or strong el ninos.

There's been a total of 3 of them, February 1983, PD2 and January 2016 (over 30")

The only exception was the exceptional January 1996.
