High for the day was 78 here.

First time since 1992 that NYC had its first 80° of the year before Newark.

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)

 

1979: This day was known as "Terrible Tuesday" to the residents of Wichita Falls, Texas as a tornado rated F4 on the Fujita scale ripped through the city. A massive F4 tornado smashed into Wichita Falls killing 43 persons and causing 300 million dollars in damage. Another tornado struck Vernon, Texas killing eleven persons.

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.

Yeah, looks like our first possible extended warm up next week as the blocking pattern which began around 3-20 begins to fade.

Friday doesn't look as bad as it had...seems like it may clear out by noon? Overnight Thurs looks the worst...

Yep we could salvage most of the next 3 days. Today looks like an overperformer on Temps

Pleasantly surprised at all this sunshine, breezy 57

Looks mostly like a spring elevated convective event now focused during Thursday night. Good MUCAPE and near record PWATS will probably result in some locally heavy downpours. So more of a spring-like feel than our other recent storms which were big washouts.

61 and sunshine. Beautiful morning

Pretty solid wind event again Thursday night

Good agreement with GEFS and EPS for that period before ridge goes away after the 20th. Hope the signal stays as we get closer to the period.

Yeah, it’s a nice improvement on next weeks forecast from a week ago.

New run

Do you think we keep the very unusual +IOD/La Niña through the fall or do you think it goes at least neutral? Although it’s possible, my guess is that we go at least neutral IOD by fall and possibly -IOD during the fall

Good question since we usually don’t see record SSTs in the NW Indian Ocean and a +IOD during developing La Ninas.

Yea and I suspect the developing Nina only serves to reinforce the -PDO

Yup. Mild and snowless

I suspect areas of metro see 80’s next week. Very likely more than once too

Yesterday was disgusting

Rain will arrive toward morning. Tomorrow will see periods of rain but it will remain mild. Much of the region will pick up 0.50"-1.50" of rain with some locally higher amounts. Thunderstorms and gusty winds are possible.

In the wake of the storm, a dry weekend will follow. It will turn briefly cooler on Saturday, but warmer air will quickly return starting on Sunday. Temperatures could again reach the 70s early next week. Even warmer temperatures are possible.

Given the near-term warmth and extended guidance, New York City's Central Park is all but certain to finish the 2023-2024 snow season with less than 10" of seasonal snowfall for a record second consecutive season. Records go back to 1869.

The ENSO Region 1+2 anomaly was -0.1°C and the Region 3.4 anomaly was +1.2°C for the week centered around April 3. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.28°C and the ENSO Region 3.4 anomaly has averaged +1.22°C. The ongoing basinwide El Niño event is fading. Neutral conditions could develop later in the spring.

The SOI was -1.08 today.

The preliminary Arctic Oscillation (AO) was +2.290 today.

Based on sensitivity analysis applied to the latest guidance, there is an implied 80% probability that New York City will have a warmer than normal April (1991-2020 normal). April will likely finish with a mean temperature near 56.2° (2.6° above normal).

This is likely a key point if one is looking far ahead to next winter. The balance of early odds seems to favor another warm winter with low snowfall, but skill this far out is essentially non-existent.

64 today, forecast was 58
