1153 PM CDT Sat Mar 18 2023
Valid 191200Z - 201200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not expected on today.
...Discussion...
As an upper low crosses Quebec and shifts into the Canadian
Maritimes today, remnant troughing extending southwestward across
the eastern U.S. will weaken/advance slowly through the period.
Upstream, ridging will generally prevail over the West, though
short-wave troughing over the West Coast states early will be
replaced by a stronger short-wave trough that should approach/reach
the Pacific Northwest Coast overnight.
At the surface, a cold front is forecast to continue moving
southward across Florida early in the period, clearing the southern
coast/Keys by early afternoon. Meanwhile, in the wake of the front,
high pressure will shift eastward across the south-central and into
the southeastern U.S. through the period.
Little lightning potential is evident onshore through Monday
morning. A few flashes may occur across southern Florida or the
Keys early, as the front progresses southward. A couple of flashes
will also be possible over portions of the Sierra of
central/northern California. No severe weather is expected.
