Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
1011 AM CST Sat Jan 28 2017
Valid 281630Z - 291200Z
...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorms are not expected in the contiguous U.S.
...Discussion...
A persistent continental-polar air mass over the northern Gulf will
preclude appreciable thunderstorm potential through tonight.
Low-level warm-air advection will increase across south Florida late
tonight and a few elevated showers may develop towards 12Z. Elevated
instability and buoyancy are likely to remain too meager to foster
charge separation.
