Has 0.30-0.35" up to ORH now...but still a bit diffuse with the precip shield...max isn't much more than that...maybe 0,40-.0.45" into N CT.

SW Berkshires/Litchfield county/TOL/southern ORH hills look like the best spots on the Euro.

Awesome! So do you think a 2-3" prediction looks reasonable in this area?

OT but best thunderstorm i've seen in a few years. Managed to get the severe out about 15 minutes in advance. Quite the light show and we had a 10-min sustained wind of 35 kt with a gust to 47 kt. Pressure kicked 2mb with the squall line meso high and the temp dropped from 68 to 59 in a minute or two.

In Bermuda? That's pretty cool. Sounds like you almost verified severe with that wind gust but if you registered 47 knots, its likely someone nearby was able to muster 50 knots.

Yeah I think its getting quite likly that at least N CT elevations will see 2-4"...perhaps some lollis higher. Berkshires and at least the southern ORH hills may cash in too. Litchfield county near Norfolk looks the best right now.

03z RPM smoked Berkshires and ORH hills...pretty far north. We'll see what happens with the SREFs and 06z NAM in 90 minutes...I'll probably be up for that sadly.

That would be perfect... it's exciting to see the Euro finally come north along with the other models.

Tolland just might be in the perfect spot for this one....of course that will make for mind numbing posts from Kevin, lol. But it looks pretty good for N CT....still have to reconcile the precip intensity, but the bulk falls between 06z and 15z which is good timing so that will help even if the snow has trouble getting more intense than moderate.

BTW, I was assuming that Bermuda hadthe same severe tstorm criteria as the US...but I probably shouldn't have assumed that. Is it the same? (50 kt wind gust and/or 3/4" hail and/or any funnel cloud/tornado)

yeah we basically decided on the same criteria. However, there is a caveat in their for squall (sudden increase of 22 kt or more)

I know the US jumped to 1" hail, but we still have 3/4"...hail is about the least likely severe weather here, anyway.

This is the same front that gave hail to E NY/W NE.

Oh jeez, I'm out of the loop on that....when did that occur? Didn't even know that. I don;t necessarily disagree with it as damage from 3/4" hail is pretty minor if not non-existent. I seem to recall very vaguely about that change now that you mentioned it, but don't remember any specifics.

i think it was by region...I think the northeast went to 1" hail around 2009? Not sure on the specific date or year.

BOX not buying anything really more than inch....

AT THIS POINT...LIKE THE IDEA OF LOWER BOUNDARY LAYER TEMPERATURES

WITH A HIGH PRESSURE TO THE NORTH. HOWEVER...THINK THE NAM IS

GENERATING TOO MUCH PRECIPITATION FOR A LOW PRESSURE TRACKING

SOUTH OF 40N. SIDED MORE WITH THE GFS/ECMWF PRECIPITATION AMOUNTS.

THE DENDRITIC SNOW GROWTH IS PROJECTED TO BE VERY HIGH ACROSS

SOUTHERN NEW ENGLAND...SOMEWHERE BETWEEN 600-500 MB /NEARLY

18000 FT UP/. THERMAL PROFILES WILL ALSO BE TRICKY...WITH

TEMPERATURES GENERALLY BELOW FREEZING EXCEPT FOR THE CRITICAL

BOUNDARY LAYER.

SINCE IT IS NOW THE END OF MARCH...THIS IS NOT AN IDEAL SETUP TO

ACCUMULATE SIGNIFICANT SNOWFALL. EXPECTING ACCUMULATIONS UP TO 1

INCH OR SO...BUT EVEN THEN MAINLY AT THE HIGHER ELEVATIONS.

I think its wrong to go less than inch if they really think that 0.35-0.40" qpf will be generated like the ECMWF...higher terrain will definitely see more than an inch of snow from that if that QPF verifies. I can see going for an inch or less if it is believed that the qpf will not be more than 0.20" or so. But I think their reasoning is poor IMHO.

The posts from Kevin are going to be vomit worthy.

Pretty remarkable jump in models, but I guess it goes back to the point about models struggling when you have a diffuse s/w embedded in fast flow. I brought this up about 2 days ago. Models always seem to struggle a bit when it's diffuse vorticity embedded in fast flow. It definitely jumped a little further north than I thought. Euro is laying an egg here. Maybe it isn't done?

The trend is good....with still over 24h to go...it might not be bad.

You would think it's done, but maybe not? I'll be surprised if it goes north again at 06z and 12z...especially when you think of where it was yesterday. That's a pretty remarkable change in sensible wx on the euro from yesterday, but it did look a little weird. I think we both mentioned how weird it was keeping a strung out mess for some reason.

SREF probs went way up

Looks like the precip max has shifted south once again to where it once was..

Close to 1" qpf for these parts.

I think you are about 25-30 miles too far south to get much snow in this...NNJ and your area may get the qpf jackpot but not the snow jackpot....snow jackpot looks like catskills to somewhere in NW CT right now.

I just looked at everything. If that weenie band comes through nrn CT or even near you, I think the DGZ is lower and decent rates can occur.. especially at 1000ft. I agree, that reasoning seems a little flawed.
