Day 1 Convective Outlook

0150 PM CST Sat Jan 07 2017

Valid 072000Z - 081200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms will affect the South Florida coast and the Upper
Florida Keys this afternoon, while a few thunderstorms are expected
tonight over parts of west-central California.

The convective outlook remains on track, with the only change being
to confine remaining thunderstorms in Florida to the South Florida
Coast and the Upper Florida Keys.  Early to mid afternoon trends in
surface observations, radar imagery and lightning data showed the
effective front moving off the South Florida Coast and through the
Upper Florida Keys.  A more moist and unstable environment south of
the front will remain supportive of thunderstorm development as the
front progresses to the south and southeast, with the thunderstorm
threat likely ending across this part of the convective outlook by
this evening.

...Florida...
A rather strong upper trough is tracking eastward across the
southeast states...pushing a cold front southward across the Florida
peninsula.  Scattered showers and thunderstorms will affect central
and south Florida this afternoon until the front moves offshore. 
While an isolated strong storm capable of gusty/damaging winds or
hail cannot be ruled out, the overall weakening wind fields and
limited convergence should preclude an organized severe risk.

...California...
Later today and tonight, an upper trough will begin to affect parts
of central California.  Cold temperatures aloft may result in a few
thunderstorms...mainly after midnight.
