Severe Weather Thread - New England

Yes... nothing to organize & sustain t-storms; these are pure pulse / air mass cells.  Weakening is not related to any sea breeze influence; air feeding into the cluster is upper 80's with +70 dp.  Would not be surprised by a sneaky outflow boundary or two allowing a couple of additional cells to pop...

Boom?

. A number of convective permitting models
simulate initial storms around early to mid afternoon across central
NY, merging quickly into a line of storms with bowing segments
depicted moving eastward into eastern NY, western and central MA
into northern CT between ~22-02z (5-10 PM). Did coordinate with SPC
and neighboring WFOs about raising the severe risk to Slight
Risk/15% into our western and central counties and a more
conditional Marginal risk to the eastern MA coast. While the most
evident severe risk lies in NY, some will likely bleed over into
Southern New England. Despite weak wind fields, this is a still a
favorable parameter space for severe storms. It`s difficult to
really message the scope of the risk given the uncertainties in the
timing. While gusty to locally damaging winds and heavy rain are the
main risks, given the depictions in the higher res models and the
level of instability that is forecast, it is not out of the realm of
possibility that corridors of enhanced wind damage could ensue into
our western-central MA/CT counties, especially if storms develop
earlier than anticipated. Pl

Seabreeze stable marine layer killed the storms

In these type of airmasses the seabreeze would actually help as they provide enough enhanced low-level convergence to spark convection. The only seabreezes kill convection is if the seabreeze has moved ahead of convection and if the airmass behind it is very stable. 

In these type of airmasses and this time of year the seabreeze isn't really going to act as a killer. 

Yesterday was a product of no forcing and no shear.

The problem is there is very little forcing. We are capped and Kevin is right...cap will erode through the afternoon as the convective temp is reached. Mesoscale features will help with storm development and maybe a cluster can organize. Despite the weak shear aloft any storms that do form will become quite intense briefly.

robability of Watch Issuance...60 percent

   SUMMARY...A small severe thunderstorm watch is being considered for
   the areas east of an ongoing cluster near the VT/MA/NY border.  This
   activity is expected to move to the I-95 corridor.  Isolated strong
   to severe gusts are possible.

   DISCUSSION...Radar mosaic shows a cluster of storms near the
   VT/MA/NY border as of 345pm.  This activity is located to the east
   of an eastward-moving MCV currently located over central NY.  The
   Albany, NY ASOS recently observed a gust of 39 kt.  The airmass over
   southern New England has warmed into the lower 90s with dewpoints
   generally in the lower 70s.  It appears at least an isolated risk
   for strong to locally severe gusts will materialize east of severe
   thunderstorm watch 432.  The overall coverage of damaging gusts is
   still in question but some risk appears to be increasing through the
   early evening.
