DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0143 PM CST FRI JAN 30 2009

VALID 302000Z - 311200Z

...NO TSTM AREAS FORECAST...

...FAR SRN FL...
19Z SURFACE ANALYSIS/SATELLITE IMAGERY SHOWED A FRONT MOVING THROUGH
FAR SRN FL AND THE KEYS...WITH A CONVECTIVE CLOUD BAND/EMBEDDED
SHOWERS LOCATED ALONG AND WITHIN THE POST-FRONTAL ENVIRONMENT OVER
SRN FL. THE LACK OF STRONGER LOW LEVEL CONVERGENCE ALONG THE FRONT
DUE TO VEERED WINDS AND WEAK MID LEVEL LAPSE RATES/INSTABILITY WILL
CONTINUE TO LIMIT THE POTENTIAL FOR UPDRAFTS OVER LAND TO BECOME
DEEP ENOUGH FOR CHARGE SEPARATION. THEREFORE...THIS OUTLOOK WILL
MAINTAIN A LESS THAN 10% PROBABILITY FOR LIGHTNING ACROSS FAR SRN
PENINSULA/KEYS.
