DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0723 AM CDT SUN APR 13 2008
VALID 131300Z - 141200Z
..NO SVR TSTM AREAS FORECAST...
..SYNOPSIS...
DEEP TROUGH ALOFT WILL BE CARVED OUT OVER THE ERN U.S. DURING THE
PERIOD AS A PAIR OF STRONG MID LEVEL VORT MAXIMA ROTATE SEWD ACROSS
THE MID WEST/LOWER MS RIVER VALLEY. THIS WILL DRIVE SURFACE COLD
FRONT SEWD OFF FL COAST DURING THE DAY. ALTHOUGH A FAIRLY
WARM/MOIST BOUNDARY LAYER WILL PERSIST OVER SERN FL AHEAD OF THE
FRONT...THERMODYNAMIC PROFILES WILL ONLY BE MARGINAL FOR DEEP MOIST
CONVECTION WITH WARM NOSE AROUND H7 WEAKENING CAPE.
REGARDLESS...APPEARS SUFFICIENT CAPE WILL BE PRESENT FOR A FEW
DEEPER CONVECTIVE UPDRAFTS AND THE POTENTIAL FOR ISOLATED
THUNDERSTORMS ACROSS SRN FL PRIOR TO FRONTAL PASSAGE.
ELSEWHERE...STRONG MID/UPPER LEVEL SYSTEM WILL CONTINUE EWD INTO THE
PAC NW AND FORCE RIDGE AXIS EWD ACROSS THE NRN PLAINS TONIGHT. AS
THIS OCCURS A STRONG SURFACE COLD FRONT WILL SHIFT QUICKLY EWD INTO
THE NRN ROCKIES AND BRING SHALLOW MOIST CONVECTION EWD AWAY FROM THE
PAC NW. HOWEVER...FORECAST SOUNDINGS INDICATE THUNDERSTORM
POTENTIAL WILL BE LIMITED.
