Valid 251630Z - 261200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Isolated thunderstorms will be possible along the Pacific Coast.
...West Coast...
Quiet convective weather is expected over most of the nation today,
with the exception of the West Coast. Strong onshore flow ahead of
an approaching upper trough will promote isolated thunderstorms in
coastal areas of WA/OR into northern and central CA. A few of the
thunderstorms may spread into the CA central valley this
afternoon/evening, where small hail may accompany the stronger
cells. No organized severe storms are anticipated.
...Ohio Valley...
Isolated thunderstorms have been occurring over the OH valley this
morning. This risk of further lightning flashes will diminish
rapidly early this afternoon as the associated shortwave trough
moves eastward and away from the region. Will leave a small area of
10% coverage for a few more hours.
