Mesoscale Discussion 1038
NWS Storm Prediction Center Norman OK
0308 PM CDT Sun Jun 28 2020
Areas affected...Southern New England Vicinity
Concerning...Severe Thunderstorm Watch 312...
Valid 282008Z - 282215Z
The severe weather threat for Severe Thunderstorm Watch 312
continues.
SUMMARY...The threat for damaging wind gusts should continue in
remaining portions of WW 312 through the afternoon. A semi-organized
line in southeastern NY would pose the greatest threat, particularly
where it interacts with remaining areas unaffected by convection.
Isolated large hail remains possible in the more discrete storms.
DISCUSSION...A semi-organized line of convection has developed in
southeastern NY. While this line of storms will carry the greatest
threat for damaging wind gusts through the remainder of the
afternoon, the exact spatial extent of the threat will be
conditional on where the downstream airmass has not been affected by
convection. Across central an eastern MA, coastal southeastern NY,
and southwestern CT, convection has been ongoing and cooled surface
temperatures. Portions of northern/eastern CT into RI as well as
northern NJ have temperatures remaining in the mid 80s to low 90s.
The wind gust threat would be maximized in these locations so long
as the airmass stays undisturbed by convection and/or stable marine
air. The threat for large hail should remain more isolated and
associated with more discrete activity.
