...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not expected tonight.
...01z Update...
Strong upper trough is approaching the CA coast early this evening.
High-level diffluent flow is overspreading much of this region and
weak convection is gradually deepening, per isolated lightning flash
over the Sierra Nevada. As midlevels cool, steepening lapse rates
should aid further destabilization along with the risk for isolated
thunderstorms.
Isolated thunderstorms have spread a bit farther downstream into
south central TX in association with the upper trough ejecting
across northeast Mexico. This activity should wane over the next few
hours.
Across the OH/TN Valleys, isolated thunderstorms are expected
along/ahead of the cold front that will advance southeast across
this region. A few lightning flashes have recently been noted across
WV, immediately ahead of the front. 00z soundings across this region
do not exhibit appreciably buoyancy, but further destabilization is
possible and this should aid a bit more coverage later this evening.
