Concerning...Severe Thunderstorm Watch 469...
Valid 292245Z - 300045Z
The severe weather threat for Severe Thunderstorm Watch 469
continues.
SUMMARY...A primarily damaging wind threat may spread south and east
of the severe thunderstorm watch 469. An additional watch is
possible.
DISCUSSION...A line of storms continues to increase in coverage and
intensity along the cold front, now approaching the ALB area and
extending southwestward in segmented fashion into eastern PA.
Around 1500 J/kg MLCAPE exists ahead of the front, along with
increasing GPS PWAT values up to 2.00" from the Chesapeake to CT.
The moist air mass, combined with lift along the front should
maintain a threat of storms along the front, with a few severe gusts
possible.
