DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0655 AM CST SAT FEB 12 2011
VALID 121300Z - 131200Z
...NO TSTM AREAS FORECAST...
...SYNOPSIS...
A DRY CONTINENTAL AIR MASS WILL PRECLUDE DEEP CONVECTION ACROSS THE
MAJORITY OF THE CONUS. ONE POSSIBLE EXCEPTION IS ACROSS THE FL KEYS
WHERE THE 12Z EYW SOUNDING REVEALED WEAK INSTABILITY ROOTED NEAR 700
MB TO THE N OF A COLD FRONT IN THE NW CARIBBEAN. HOWEVER...THERE IS
LITTLE LARGE SCALE SUPPORT FOR ASCENT OVER S FL AND THE KEYS...AND
GRADUAL MIDLEVEL DRYING FROM THE W/NW WILL END ANY POTENTIAL FOR
WEAK CONVECTION TODAY.
