March 5-8 storm discussion

I never knew you were so into rain and flooding. Makes sense now..I just put all the pieces together

i've never really seen a flood so can't say i'm into it or not.

it doesn't happen down here. coastal flooding does obviously but other than urban area/street/basement type flooding the combo of sandy soil and no rivers makes flooding pretty much non-existent here.

This upcoming event looks very different from those past 3 in terms of the presence of a very strong, cold high over Quebec, as you noted. A pattern like that would tend to support more widespread ice, while a pattern with poor high placement and little cold air damming (as we saw in the Feb 5, 25 and 28 events) only supports icing in climo-favored areas.

Feb 5- no high

Feb 25 - 1035 mb high over the northern Rockies with arctic front oozing in toward end of event

Feb 28 - ~1027 mb high retreating toward Newfoundland

Three times in February alone...this past event you flipped to a 34F rain for hours and hours while it was 30-31F up in this area. Feb 25th event we iced all afternoon while you were mid 30s and rain, and then the Feb 5-6 event...marginal ice while it was all rain S of the pike.

I think it will just depend on how well the LL cold can get transported. Dec 11, 2008 had a 1033-ish well placed high over Quebec and the cold never really got S of the pike except in NW CT hills well over 1000 feet.

If the sfc low stays decently SE, then it should be able to drag the cold pretty far SE too. Though in that case, it might mean more snow for the NW interior areas and maybe a stripe of icing further SE.

From the trend on the models and the research energy peak on March 7th, I believe that a major snowstorm is almost a lock now, the question being what parts of New England and upstate NY get into the snow. Would say at this point the chances look best for w MA and nw CT as well as upstate NY, e ON, s QC, VT, n NH and inland Maine.

Chances for eastern MA, RI and most of CT, LI, NYC seem to depend on storm becoming more intense without track shifting north. This is still plausible given the large-scale features.

This could in fact be one of those events that looks fairly good at five days and then really good at 2-3 days, locking into an obvious "blizzard" scenario with model consensus. Keep your fingers crossed (unless you're one of those normal people who don't want a disruptive weather bomb).

Are there climo factors at play here? Off-hand I don't recall too many severe icing events in CNE after March 1. Not saying its impossible obviously, just wondering what the track record has been

I wonder if this storm will finally melt my invincible snow pack.. I expected it would be all gone after I got back after this weekend.. but I still have a solid 4-5" in middle of open fields. 2 months of snowpack on the shore in SE CT .. who would of thought.

We're still clinging to some snow on north-facing lawns and wooded areas...not solid coverage but not just piles either. It should stick around until the weekend's rain, been an incredible run for snowpack for those who live near the coast, the likes of which we may never see again.

Real question is: can we add a few more snow cover days with the bomb the ECM shows in the LR? Cut-off season FTW.

I approve this message. ;)

And a lovely afternoon out here now ..down to 21F and windy.

I was down in Queens yesterday and pretty much gone all over the NYC area... I didn't see much solid cover on the west side of the river until I got above Newburgh. Some scattered in the woods yes. But the east side of the Hudson was catching those storms more being on the border of NE.

Lots left here of course ...but Sunday won't help.

Neither the ALY nor BOX AFD's are saying much about wintry with the upcoming systems. They ahve the front end snow in areas but seem to be talking mostly rain with lackluster comments re: wintry on the back end. Hmmmm

I could go for a big blizzard to keep me from haivng to fly to IA on Tuesday.......

27.6/11
