Valid 270100Z - 271200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not forecast through tonight.
...Discussion...
Scattered showers persist this evening from parts of CA into
northern UT, north of the midlevel jet with cool temperatures aloft.
With the loss of heating and in the absence of significant
large-scale ascent, a steady downward trend is expected through late
evening. Given weak instability coupled with a cooling boundary
layer, severe storms are unlikely.
To the east, a midlevel wave continues to move across the Mid
Atlantic, with scattered low-topped showers from WV across the warm
front into PA. The 00Z PIT sounding shows weak elevated instability
sufficient for a few lightning flashes with the larger batch of
precipitation as it pushes east across the remainder of PA, NJ, MD
and DE.
