I am...I just saw a forecast for 8-12 inches of snow in the Poconos?! Thats amazing!

How does this storm compare to April 19-20, 1983?  No one has been willing to post maps of that amazing storm lol.  Our latest accumulating snowfall!

This is a much warmer storm for the coast than that one since we will have a +AO spike tomorrow. So the storm is going hug the coast instead of taking a BM track. But the higher elevations will get a heavy wet snow. The late March strat warming really primed the atmosphere for blocking with the near record weak SPV. This phasing storm Monday night will really pump the -AO block. Probably the most -AO of the year near -2. I think the 88° high at Newark on the 14th will stand as the warmest of the month. The late month blocking will probably favor an active backdoor pattern.

The 1983 storm brought accumulating wet snow to much of the area but changed to rain fairly quickly along the coast.  Some Coastal areas received up to a couple of inches before turning to rain.  Parts of NW NJ received up to 15 inches with this event.  I have not seen any accumulation maps regarding this event.

Today featured brilliant sunshine but unseasonably cool readings. The colder than normal readings will likely persist through at least midweek.

Before then, a storm could bring a windswept rain to the region tomorrow night into Tuesday. A general 0.50"-1.50" rainfall with some locally higher amounts appears likely. Snow is likely in the higher elevations and in the interior. The Poconos, Catskills, and Adirondacks could see at least an appreciable accumulation of snow.

The ENSO Region 1+2 anomaly was -1.1°C and the Region 3.4 anomaly was -0.9°C for the week centered around April 6. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.73°C and the ENSO Region 3.4 anomaly has averaged -0.92°C. La Niña conditions will likely persist into the start of May.

The SOI was +18.75 today. During April 5-14, the SOI had a 10-day stretch during which the SOI was +20.00 or above. The last time a streak of 7 or more such days occurred in April was March 28-April 5, 2011 when the SOI reached at least +20.00 on 9 consecutive days. Then, there was a brief period of much warmer than normal temperatures following the end of that stretch and a longer period of much warmer than normal temperatures starting about 2 1/2 weeks later.  

The preliminary Arctic Oscillation (AO) was +0.782 today.

On April 15 the MJO was in Phase 8 at an amplitude of 1.014 (RMM). The April 14-adjusted amplitude was 0.828 (RMM).

Based on sensitivity analysis applied to the latest guidance, there is an implied 57% probability that New York City will have a warmer than normal April (1991-2020 normal). April will likely finish with a mean temperature near 54.0° (0.3° above normal).

Yep, whenever you see those troughs developing over the Maritimes this time of year you know what’s coming. Blocking at the worst possible time once again.

If that 12z GFS is true then I'm in big danger of losing my bet.

It's a very bad pattern. I think we'll hit 70 late this week, maybe even 75 or 78 but after next weekend, we're going to be below normal temps and near normal precip for a while IMO. I don't think Central Park is going to get to 80 this month. Though we should see much more warmth possibly heat starting around mid or late May.

I anticipate we’ll fall short on Friday. I do think we have a shot for the beginning of next week, though. If we get it on the 25th I win my bet. The end of that week looks on the cool side, though.

Morning thoughts…

Clouds will increase during the day and rain will likely arrive late in the day. Overnight into tomorrow morning, there will be a windswept heavy rain. Higher elevations and interior sections will likely see some snow. High temperatures will likely reach the lower and middle 50s in much of the region. Likely high temperatures around the region include:

New York City (Central Park): 53°

Newark: 54°

Philadelphia: 54°

The cool weather will continue through at least midweek.

Normals:

New York City: 30-Year: 63.0°; 15-Year: 63.3°

Newark: 30-Year: 63.8°; 15-Year: 64.1°

Philadelphia: 30-Year: 65.8°; 15-Year: 66.3°

At Bismarck, 2.5” of snow fell yesterday. That broke the daily record of 2.1” from 1959. It also increased the snowfall for this month to 21.9”, making 2022 the snowiest April on record. The old record of 21.8” was set in 2013. April records go back to 1875.

Our big temperature swings pattern continues. Newark dropped  50° degrees since last Thursday. Upper 80s to upper 30s is one of the greatest 88 hour temperature drops in Newark during April. It would be a little higher if off hour highs and lows were included.

Cold morning in West Jersey, colder than forecast.  Looks like some of the coldest in the region.  I had a low of 25 (forecast was 31).  I went ahead and put a few pansies in, since they are allegedly colder weather plants, so we'll see how they did.  Right now they are looking pretty iffy.

April -AO blocking since 2004 has usually continued into May.

Frosty 28°

 "Warmed" up to 41° @ 0755 and now already @ 48°.  Not so sure with all the blocking that this is the last freeze, but hopefully.  Nice to garden without row covers or cloches, but this seems to be our climate, so take any warm breaks we get.  Colder times only make the warmth feel better.  Maybe the inverse in winter.

Good morning all. Ref: NOAA; sometime between 4 and 5:51 the CPK low was 39 degrees. Sunshine over the postage stamp right now. Below is a screen shot sample of the weather alert that is delivered by our local zip digital news called Patch. Stay safe and dry tonight. As always ….

Felt like a late fall/early winter morning.

In the Herndon-Reston area of northern Virginia, (NW of D.C.) currently light rain mixed with ice pellets.

It is presently snowing hard along I81 in south central PA well to the SW of Harrisburg.  I am seeing visibility’s as low as 1/4 mile with accumulations on grassy surfaces near the Maryland border.  Elevations there run about 500-700’.
