Why is it our local broadcasters almost uniformly underforecast the temperatures, Don? I even heard them say "no 70s for the next 7 days" and they busted badly on the first day of that forecast!

 

Have to tack on 3-5 degrees on sunny to partly sunny days in early spring to account for lack of vegetation IMO.

Historical:

 

1885: A tornado struck the town of Denison, Texas in 1883 that destroyed a church. The congregation rebuilt the church. On this date, a second tornado destroyed the newly rebuilt church.

1958 - Portions of Montana were in the midst of a spring snowburst. Snowfall amounts ranged up to 55 inches at Red Lodge, 61 inches at Nye Mine, and 72 inches at Mystic Lake. (David Ludlum)

1967 - Severe thunderstorms spawned 48 tornadoes in the Upper Midwest. Hardest hit was northern Illinois where sixteen tornadoes touched down during the afternoon and evening hours causing fifty million dollars damage. On that Friday afternoon tornadoes struck Belvidere IL, and the Chicago suburb of Oak Lawn, killing 57 persons. (David Ludlum)

1980 - The temperature at International Falls MN hit 90 degrees. (The National Weather Summary)

1987 - Unseasonably warm weather prevailed from the Gulf of Mexico to New England and the Great Lakes Region, with twenty-nine cities reporting record high temperatures for the date. Afternoon highs of 82 degrees at Caribou ME, 94 degrees at Mobile AL, 95 degrees at Monroe LA, and 93 degrees at New Orleans LA, were records for the month of April. (The National Weather Summary)

1988 - After having had just twelve rainouts in the previous twenty-six years at Dodger Stadium, a third day of heavy rain in southern California rained out a double-header at Dodger Stadium which had been scheduled due to rainouts the previous two days. (The National Weather Summary) (Storm Data)

1989 - The temperature at Las Animas, CO, soared to 100 degrees to establish a state record for April. Twenty-two cities in the central and southwestern U.S. reported record high temperatures for the date. Eight cities equalled or exceeded previous April records. (The Weather Channel) (The National Weather Summary)

1990 - Afternoon and evening thunderstorms produced golf ball size hail in Oklahoma, and also caused some flash flooding in the state. Thunderstorms over the Southern High Plains produced golf ball size hail at Roswell NM and El Paso TX. Easterly winds and temperatures near zero produced wind chill readings as cold as 50 degrees below zero for the spring festival (Piuraagiaqta) outdoor events at Barrow AK. (The National Weather Summary) (Storm Data)

2007 - The South Plains and Panhandle of West Texas were hit by an outbreak of severe thunderstorms. Between the hours of 5 and 6 pm, several thunderstorms developed across the western South Plains. Around 7 pm, a supercell produced a tornado which touched down around Fieldton (southwest of Olton) and then moved just south and east of Olton, doing damage to several structures and equipment. The thunderstorm continued to move northeast across northeast Lamb, northwest Hale, southeast Castro and southwest Swisher Counties, producing a long-lived tornado (along with hail up to the size of tennis balls). By 7:45 pm, the storm approached the town of Tulia in Swisher County. A tornado touchdown was reported in the town, causing major damage. The tornadic thunderstorm continued to move northeast across Swisher County over open country through about 8:30 pm. (NWS Lubbock, TX)
 

wow it was so cold in the early 80s, even this late in the season

below freezing on this date in 1981!

April blizzard in 1982 and another snowstorm a week later!

April snowstorm in 1983 on 4/20!

Models back to a stronger cold front this week with a piece of the TPV heading for Maine. So interior sections need to watch for a hard freeze. NYC may dip below 40° which will feel very chilly for late April. The low pressure will become the new 50/50 low which has been so persistent since late March. So more continuing backdoor potential.
 

 

are we returning to early 80s type weather in spring lol?

It was below freezing on this date in 1981 and of course we know what happened in 1982 and 1983 also had a late April snowstorm on the 20th.

36F this morning, chilly but we still get 30s into May some days. 

2020 was the rare outlier, I can't remember the last time before that NYC got into the 30s (actually I do-- I think it was May 1992 when we were in the upper 30s-- that was the "Pinatubo summer"-- I think before that the last time we were in the 30s in May was in 1977, when we had snow, just like what happened in May 2020.)

So 30s in May is basically a once in 2-3 decade event.

To my knowledge it has never hit freezing or below later than 4/20 (which happened in 1983 when we had snow that actually stuck.)

Daylight:   13H:34M  Roughly equivalent to Aug 21

A little less than 2 hours to go until we reach maximum daylight in about 2 months.

Time seemingly moving so fast.

I like the Jan 15 - 19 - 1994 up and down

Rain to about Cap May cloudy and 48 here.

i feel euphoric over this weather cloudy and chilly

Funny thing about 2007-- the first three weeks of January were warmer than the first three weeks of April lol

[Stormlover74]

With the rest of the month looking fairly dry we may end up falling below average for April. Certainly didn't seem possible after receiving 3" the first week

I'm not it's reaching the ground. Forecast for cape may is cloudy with no chance of rain

That was an extension of the March pattern.  I wonder taken collectively if it was one of our wettest 5-6 weeks periods ever.

 

[winterwx21]

Nasty today. Only 51 degrees here right now. 

Not much to talk about for awhile. Finally in a dry pattern. Maybe just a shower on Wednesday. Pretty much just normal temps (maybe slightly below a couple days) for late April over the next week with highs in the 60s. Boring weather ahead, but I'm ok with boring for awhile after all the rain we've had in recent months.

I must recommend a Helly Hansen - easily the best rainy/ snowy weather jacket I’ve had. Best. North Face and Oros - pass. If of course you don’t have one.

I would settle for boring hopefully the next couple of weeks. Our rivers and streams deserve a much needed break. Besides I got a hunch we’re going to deal with a couple of tropical threats this summer with a hyperactive hurricane season looming.

Despite the rapid arrival of clouds, spring is in all its spectacular glory at the New York Botanical Garden.

[donsutherland1]

Under mainly cloudy skies, much of the region struggled to reach the low 50s. Tomorrow will be somewhat milder, but generally cooler than normal conditions will likely persist through most of the week.

It could turn warmer as April concludes with May starting with warmer to much warmer than normal temperatures.

The ENSO Region 1+2 anomaly was -0.2°C and the Region 3.4 anomaly was +0.9°C for the week centered around April 10. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.10°C and the ENSO Region 3.4 anomaly has averaged +1.15°C. The ongoing basinwide El Niño event is fading. Neutral conditions could develop later in the spring.

The SOI was -4.33 today.

The preliminary Arctic Oscillation (AO) was -0.594 today.

Based on sensitivity analysis applied to the latest guidance, there is an implied 74% probability that New York City will have a warmer than normal April (1991-2020 normal). April will likely finish with a mean temperature near 54.9° (1.2° above normal).

The -30C 850 mb temperature near James Bay is close to the record for late April. It looks like the TPV splits in a few days and a piece heads for Maine. So NYC has a shot at dipping under 40° with the interior northeast having a hard freeze potential.

It's pretty rare to get below 40 degrees after 4/20, it's only happened a handful of times in my memory (and most of those were actually in early May like 2020, 1992, etc, and of course there was 1977.)  1983 stands out with a snowstorm on 4/20.
