..no severe thunderstorm areas forecast...
a few thunderstorms are possible across parts of California into the
Great Basin on Thursday. Severe weather is unlikely.
A shortwave trough will dig southeastward toward the Great Basin
with substantial cooling aloft and lift resulting in widespread
precipitation. Minimal instability will exist across California during the
day and developing into the Great Basin, due to steepening lapse
rates aloft. Sporadic lightning strikes will be possible from California
into Nevada and Utah as a cold front progresses eastward. A few strong
wind gusts may occur as a result of downward mixing of strong winds
aloft, but severe weather is unlikely.
Elsewhere, a fast moving shortwave trough will move east from the
mid MS valley early in the day to the mid Atlantic coast by late
evening. Cold air aloft may support minimum elevated instability
across Kentucky and TN, but the overall thunderstorm threat is quite low.
