..no severe thunderstorm areas forecast...
a few thunderstorms are possible across parts of California into the
Great Basin on Thursday. Severe weather is unlikely.
..synopsis and discussion...
A shortwave trough will move southeastward across California and into the
Great Basin with substantial cooling aloft and lift, as well as
strong wind profiles. Instability will be weak across the region,
but strong lift and steepening lapse rates aloft will likely result
in sporadic lightning strikes from California across Nevada and perhaps into
western Utah. Lift will be maximized Thursday morning across the
Sierra with strong upslope flow, and will progress east across the
Great Basin in association with a cold front. A few strong wind
gusts may occur with precipitation along the front, but severe
weather is unlikely.
