Next Monday-Tues frontal passage


free_man

Recommended Posts

BUFKIT is actually a little more impressive tomorrow for BAF and ORE. Showing @ or > that 1,000 SBCAPE and brief spike in helicity to 120 around 7pm, at which time llv cap is temporarily desolved - abused by evaporating towers at dusk. I could see an isolate interesting cell or two late tomorrow.

As for Tuesday, it looks like we CINH ahead of the fropa - could just be the one run but the lower troposphere wind at both locations backs wnw and it's over by 1pm... I'm wondering if there's a prefrontal trough that acts like a dry line and then whips out to sea. I have seen impressive set ups get robbed away to anitclimax results because of the idiosyncrasy of New England's home grown "dry line"

watched NECN and Tim Kelley tonight...he expressed the same concerns...

I really would not be surprised to see a FROPA actually past 0z which would still be great, especially for northern sections. This would certainly allow for sufficient heating/destabilization and shear actually increases even more late in the evening and helicity even spikes a bit.

NAM looks decent on the 00z run. It looks like it has a pre-frontal feature go through late aftn, with the actual cold front coming through early evening. Maybe a few storms along that as well.

I would actually prefer for the storms to be associated with the pre-frontal trough, especially if you want discrete development, however, it all depends on the wind direction too, if BL winds are veering (such as what the NAM kind of hints at) more to the west that is not good at all. If those BL winds and sfc winds can be more S/SW it would be much more beneficial.

It's impossible to pinpoint something like that though this far out.

0z GFS did slow down a bit...6z NAM slower as well and highly unstable, even though those dews are high they may be pretty close to verifying as some really juicy air gets pumped in. Still dealing with the same issues basically; mainly with what the winds do in the BL and at the sfc...if they do veer west at all it will really dry things out and perhaps mix out the dews lowering the svr threat; if they can stay SW or even S that will keep the dry air from mixing down and it will increase convergence either along the pre-frontal trough or cold front and enhance svr threat.

Damaging winds look to be the main threat along with torrential rains/flash flooding...can't rule out some hail though, especially in the really strong updrafts or any discrete storms.

I think we (someone) gets destroyed before the cool, dry airmass punches in, personally. That probably deserves a few buns, :snowman: I'm liking the setup despite a few negatives still lingering. Watch, we get a dry cf passage now.

I'll be in Waltham in the morning and then Boston after lunch all day tomorrow for the kick off to our fiscal year..Doing some sort of fun/secret actvity. Hopefully Eastern mass won't disappoint me for severe tomorrow

that is like someone from the Monads traveling to NYC and hoping winter doesn't disappoint them.

Where's the best SVR threat as of now?

Moderate risk for lower lakes/ upper OV . GOOD sign

And SPC earlier today

...NEW ENGLAND...

MODEST DESTABILIZATION AHEAD OF THE PASSING COLD FRONT WILL ALLOW

STORMS -- POSSIBLY ONGOING OVER PARTS OF THE AREA EARLY...TO EXPAND

IN COVERAGE AND INTENSITY WHILE SPREADING EWD ACROSS THE AREA.

AIDED BY MODERATELY STRONG/ROUGHLY UNIDIRECTIONAL WLYS THROUGH A

DEEP TROPOSPHERIC LAYER...ORGANIZED STORMS -- LIKELY EVOLVING INTO

LINEAR CLUSTERS -- SHOULD MOVE QUICKLY...ACCOMPANIED BY THREAT FOR

LOCALLY DAMAGING WINDS. STORMS SHOULD WEAKEN/MOVE OFFSHORE BY

EVENING.

Is that for today of tomorrow?

What are we looking at for timing wise?

I guess something after 1pm. Maybe 4-5 for BOS on se. It's really close for MHT since the pre frontal trough might already have passed by at that point. If that's the case, then you have to hope some stuff fires along the actual CF, which may be more hard to do.

That might mean CT is too far west tomorrow which would just destroy Wiz

Thanks.. so we want a slow down of the front today? Hopefully that's the case. Could use some rain today

ha.

SnowNH, Looks like Wednesday (after all) will be the best chance of storms for S NH....with the colder upper level airmass and less downsloping. We always do better with a NW to N mean wind, or SW to S...but never west. That also can apply to winter. Not to turn this into a SNH thread, just to keep snowNH from bombarding with the IMBY posts.
