Day 1 Convective Outlook

1009 AM CST Sat Nov 11 2023

Valid 111630Z - 121200Z

....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
A few lightning flashes will be possible across northwest Washington
and central Florida today.

....WA...
Relatively dry and stable conditions will preclude thunderstorms
over most of the CONUS today.  However, a few lightning flashes will
be possible over northwest WA as a strong westerly upper jet and
cold temperatures aloft spread across the region.  Lightning has
been observed over Vancouver Island this morning, and further
activity is possible as the strongest forcing moves eastward this
afternoon.

....FL...
Other lightning flashes may also occur over portions of central FL
this afternoon and early evening.  A warm and humid low-level air
mass is present, coupled with marginal CAPE values.  Despite weak
large scale forcing for ascent, diurnal heating and weak sea-breeze
convergence will result in scattered showers and perhaps a
thunderstorm or two later today.
