28.5 last night, 7 below forecast. Last freeze is the year for sure 

Not necessarily. Models have a quick deep trough after the near record warmth this week. 

[SACRUS]

Up to 52 with bright sunshine after a low of 29.  Week of warmth and sunshine 4/10 - 4/16, before we cooldown between 4/18 - 4/21 or so.

Historical:

 

1877 - Oregon Inlet, NC, was widened three quarters of a mile by a nor'easter. (Sandra and TI Richard Sanders - 1987)

 

1889: The Norfolk Landmark reported that damage was more substantial than the August 1879 hurricane because it lasted for a much longer duration- the water was 18 inches higher. Rain, snow, and sleet fell, totaling 3.2 inches. Drummonds Bridge was swept away (later replaced by the Ghent Bridge). Trees were uprooted, and roofs were torn off.

1947 - A tornado struck Woodward, OK, during the late evening killing 95 persons and causing six million dollars damage. The tornado, one to two miles in width, and traveling at a speed of 68 mph, killed a total of 167 persons along its 221 mile path from Texas into Kansas, injured 980 others, and caused nearly ten million dollars damage. (David Ludlum) A man looking out his front door was swept by a tornado from his home near Higgins TX and carried two hundred feet over trees. The bodies of two people, thought to be together at Glazier TX, were found three miles apart. (David Ludlum) (The Weather Channel)

 

1953: The first radar image of a tornado was detected by radar equipment at the University of Illinois Airport at Champaign, IL. Studies of the radar pictures from that day showed that a tornado of significant size and intensity could be detected.

1977 - A storm brought 15.5 inches of rain to Jolo, WV, in thirty hours. (The Weather Channel)

1987 - International Falls, MN, reported their sixth straight record high for the date, with a reading of 77 degrees. A cold front ushering sharply colder weather into the north central U.S. produced wind gusts to 60 mph at Glasgow MT. (The National Weather Summary)

1988 - Residents of Sioux City, IA, awoke to find two inches of snow on the ground following a record high temperature of 88 degrees the previous afternoon. (The National Weather Summary)

1989 - Eighteen cities in the southwestern U.S. reported new record high temperatures for the date. The afternoon high of 80 degrees at Eureka CA established a record for the month of April. (The National Weather Summary)

1990 - Thunderstorms developing ahead of a cold front produced severe weather from the Central High Plains to Arkansas and northern Texas. Severe thunderstorms spawned five tornadoes, and there were seventy reports of large hail and damaging winds. A tornado injured four persons at Ardmore OK, and thunderstorms produced wind gusts to 70 mph at Kellyville OK, and hail three inches in diameter at Halmstead KS. (The National Weather Summary) (Storm Data)

2011 - An EF-3 tornado hits Mapleton, IA. Officials estimate more than half the town is damaged or destroyed but none of the 1200 residents were killed. 31 tornadoes were confirmed across Iowa, Kentucky, Tennessee and North Carolina on this day.

I think that this month may not end up in the top ten warmest Aprils. It looks to me like the NYC Metro Region has two very above normal days then a little less above normal for a day or two then probably near to perhaps slightly below normal normal for the rest of the month and kind of wet. My thinking is that we might have to wait several weeks before we get into more above normal temperatures again, sometime around mid May. But Thursday & Friday this week could be mid-upper 80s with a chance that somebody hits 90.

Hopefully NYC hits 90 before the foliage comes in and ruins it.

This must have been the last of the cold as 90 was hit later in April.

Sun light Day length 13H and 1M Roughly equivalent to  September 2nd

It's the anniversary of the April 9-10, 1996 snowstorm forecast was for 6-12 inches in NYC which was a bust for the city, but we did get 4-5 inches here near JFK with over a foot to 16 inches in eastern Long Island.

Well remembered for the snowy Yankee stadium opening day which Andy Pettitte pitched with snow accumulating on his cap lol.  The snow seemed to get heavier throughout the game.

i have enjoyed wearing my winter coat hat and hoodie the last few days..

Some early April scenes at the New York Botanical Garden.

[donsutherland1]

Today was a glorious early April day with deep blue skies, bright sunshine, and pleasant temperatures. 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.

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)

Yesterday, it was noted that based on historic climate data, New York City's current warmer climate regime, and the latest guidance, 2022-2023 will finish with the lowest seasonal snowfall on record (2.3"). Although it is far too soon to really look ahead, none of the ten seasons with less than 10" snowfall were followed by a second consecutive season with less than 10" snowfall. 1997-98 (3.5") and 1998-99 (12.7") came closest. Half of those seasons were followed by 30" or more snowfall.

However, a very low snowfall amount cannot be ruled out. First, New York City is in a much warmer climate regime than had been the case for most of those prior seasons. Second, there is the risk of a strong El Niño following on the heels of a La Niña. Such a sequence often leads to very low snowfall. For now, all of that is just speculation.

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 29. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +1.38°C and the ENSO Region 3.4 anomaly has averaged -0.08°C. Neutral ENSO conditions will likely prevail through at least mid-spring.

The SOI was +21.70 today.

The preliminary Arctic Oscillation (AO) was +0.276 today.

On April 7 the MJO was in Phase 6 at an amplitude of 1.204 (RMM). The April 6-adjusted amplitude was 0.941 (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.

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’s exactly what happened last April. Anyway, models are suggesting that the cool-off peaks around the 19th then it trends warmer again.

A nice, cool night at my sister’s place on the water:

We’re at exact opposite ends of TR.

EPS is right about normal. I'm really not at this point seeing ensemble maps that would support above normal temperatures for the last 8 or 9 days of April.

Probably because it’s too early to make any forecast as to what the final week of April will look like. I mean two weeks ago there was no sign of any warmth for this upcoming week.

Actually there was. Almost every GFS operational run then CMC and Euro showed it clearly. In April when you get 564dm thicknesses here on light northwesterly winds or light variable winds and no moisture around you're going to be above normal.

There’s really no consensus on what’s going to happen past the 19th. The Euro ensembles show everything all over the place the following four days. And it’s way too early to make any predictions on anything in the last week of April.

[LoboLeader1]

Currently 40F here as of 9:15PM.

[Volcanic Winter]

26 here, a degree colder than last night. 
 

TR station further east is at 30 so I’m four under them.  

[gravitylover]

34 here on the hill, 27-29 down by the river. There's a nice, thick frost coating on the cars. 

[CIK62]

The next 8 days are averaging    66degs.(57/75) or +13.

Month to date is    52.9[+3.3].       Should be     59.1[+7.8] by the 18th.

Reached 52 here yesterday.

Today:   58-62, wind w., m. sunny, 53 tomorrow AM.

Maybe two BN days in the next 16 days:

42*(72%RH) here at 7am.      44* at 8am.       46* at 10am.     50* at 11am.       51* at Noon.    Reached   55* at 1pm.       51* at 8pm.

Summer seasonal forecast:

The above map would imply that the New York City area could see a summer that could rank as cool as 24th hottest to as warm as 4th hottest. Much can still change before the final map is issued next month. The overall theme is for widespread warmth in the Northern Hemisphere. The rapidly developing El Niño event should also produce a generally warmer than normal winter across much of the Southern Hemisphere.

29 this morning. Impressive radiational cooling last few nights 

[SACRUS]

 

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.

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.

Quick recovery today, up to 62 now. Very likely we hit 80 later in the week.
