FWIW... The RAP really stalls the front out over CT/RI later.

Mesoscale boundary interactions will likely lead to a messy day of convection in southern areas with sea breeze fronts and terrain producing all sorts of crap lol.

Yeah maybe a south coast convective day?

The threat locally for something truly interesting today looks to be confined to a very small area, basically southern CT into the NYC metro, in an equally small temporal window from mid afternoon until dark, which is maybe why SPC is ignoring it. Could be a nice surprise supercell or two, maybe, if a couple of models are to be believed. Low level shear isn't really sufficient, so it would probably require a sea-breeze or other boundary in just the right place and time... One can hope, anyway. Be nice if this happens.

Agreed. Models have outlined this area for the last 36 hours really.

Deep layer shear does increase a bit this afternoon across CT and the Hudson Valley. So we do approach 30 knots of 0-6km of deep layer shear which isn't awful especially given >2000 j/kg of MLCAPE.

MCD...watch unlikely

Actually, it is almost certain. Dueling MCDs, never really seen that before... New MD text:

PROBABILITY OF WATCH ISSUANCE...95 PERCENT

SUMMARY...POTENTIAL FOR STRONG TO SEVERE STORMS MOVING INTO THE NYC

METROPOLITAN AREA THROUGH THE LATE AFTERNOON ON A HOLIDAY WEEKEND

SUGGEST THAT A WATCH IS WARRANTED.

DISCUSSION...ENVIRONMENTAL CONDITIONS HAVE BECOME FAVORABLE FOR

Bizarre. As is the text in the second MCD. They seem to have issued it because of the holiday weekend and the threat being in NYC metro lol.

Yep, bizarre is the word. They took that second MCD down pretty fast, blink and you missed it, and the watch that was eventually issued doesn't even mention it, there's no "related MCD" link like there usually is. I think they're a little ashamed of it.

I'm interested to see what happens when the sea breeze front interacts with the cold front. Front is between HFD and BDL. So it will be soon that we start to see some interaction. May be the needed lift to break through the minimal remaining CIN.

Think this part of ct is in the game?
