Hurricane Agnes

I was trying to see if there may have been some initial mixing and then a backend thump. The sheer quantity of the first one for some locations was significant nonetheless and unless you had a rapid warmup and near flooding rain (like what happened in 1996 and even that didn't take it all away), then there would have been snowpack still there for the next storm. There is a cool site that had some snow maps of those 2 events (and some other area HECS/SECS over the years) - https://www.weathernj.com/major-new-jersey-snow-storms/

Probably in 2009/2010 - the banner season where I measured something like 70" IMBY (and almost 58" for the 2010 calendar year alone). And snow on snow for South Jersey/Delaware would have happened with a 2/5 - 2/6/10 storm followed a few days later by a 2/9 - 2/10/10 storm (with Delaware's totals coming in worse in some cases, than Jersey with the 2nd storm) - Winter Storm Feb 5-6, 2010 https://www.weather.gov/phi/02052010 Winter Storm Snowfall Totals Feb 9-10, 2010 https://www.weather.gov/phi/20102010 That first hit left 15" - 24" at the shore and wouldn't have disappeared 3 days later before the next round came in with an additional range of 3" - 12" (depending on location).

So far it looks like my low this morning was 19 (coldest of the season and year so far) and am currently at 20 with dp 12. Am getting a deck of cirrus drifting in but otherwise the sun is in and out. Mt. Holly tweeted out their preliminary snow reports last night - Also had their 11:36 pm list after the above (KPHL finished up with 1") -

Everybody cherry-picked around the GFS & ICON (but then these are all 18Z and will have to see what the 0Zs do). Temp down to 27 here with dp 14.

Finished up with a trace! Temp is down to 28 with dp 14 and I know it may have still going on in some places after the report, but here was the PNS as of 4pm and you can see who really cashed in within the CWA (KPHL managed 0.5") -

Concern might be for sleet (and we sure as hell had a lot of that last year). Still have some time...

That's why I put up that fantasy GFS 1/16 storm. As shown, it looks "juicy" and if there's enough cold air from the north (and the temps stay below or near normal the next 10 days vs above normal), it could sortof bomb out and provide some evaporative cooling back to the west.

I would agree if it were a PD storm but for early January, after near record-breaking antecedent temps? It's a bit marginal.

Yeah - this MLK Day specia!

If that position of the low verified as shown, it would be a bit close to the coast and could cause mixing issues.

The mood flakes that appeared here earlier evaporated with the 18 dp and temp at 31. Even the radar wiped the virga clean. Cloud deck is trying to brighten to the west.

Now getting some hard-to-see mood flakes but they are there. temp 31 with dp 22. Heavier returns are slowing pushing northward. Spotter in Dunkirk, MD reporting 10".

Dp has dropped to 21 here with temp 31. Still virga at the moment. Looks like southern MD & eastern VA has reports of 6" - 7" already. Spotter in Absecon reporting 4.5" and someone at Somers Point reporting 5.5".

WPC's approx. (sat) position about 40 minutes ago, of the low that will go coastal soon - Temp holding at 31 IMBY with dp 23 so some dry air...

Pancake flakes and nice breakers going on down there (plus it's a New Moon so some generally higher tides).

Well the soon-to-be-coastal hasn't "coastaled" itself yet but once the low gets out there, there could be some wrap-around bands that pivot up here. Currently holding more at 31 now with dp 24.

Virga has evaporated here and it is overcast with temp bopping between 31 and 32 with dp 25. Far south Jersey and coastal DE looks to be getting rocked. The Carolina low is inching towards the coast but doesn't seem to be moving that fast.

LOL @ Mt. Holly effusive AFD - Latest from Mt. Holly on forecast - It is a pretty presentation. Still have virga and temp is now down to 32 with dp 25.

I think everyone was waiting for your check-in.

Virga here so far with temp 33 and dp 26.

Currently 33 with dp down to 27 so conditions are ripe for something (although the ground is warm). Looks like Salem County and Newark, DE area under some heavier returns.

If the eyes blend in with any flakage, then I'll SOL with finding a target.

Getting a temp/dp drop and now down to 46 with dp 41. Here is what WPC posted about an hour ago -

I was looking at -30F temps in the upper midwest this morning so that cold blob means some serious business. How far it oozes down with the jet and how dry it is, will make a difference where the gradient sets up. I wouldn't be surprised if there is some convection with it too in the southern parts of the CWA.
