DAY1SVR: Day 1 Convective Outlook

ACUS01 KWNS 050045
SWODY1
SPC AC 050043

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0743 PM CDT WED MAY 04 2011

VALID 050100Z - 051200Z

...NO SVR TSTM AREAS FORECAST...

LIGHTNING REMAINS SPARSE ACROSS THIS CONUS THIS EVENING DUE
PRIMARILY TO MEAGER INSTABILITY WHERE LARGE SCALE FORCING WOULD
OTHERWISE SUPPORT DEEP-MOIST CONVECTION. ISOLATED THUNDERSTORMS
ACROSS THE CNTRL/SRN FL PENINSULA SHOULD GRADUALLY WANE IN INTENSITY
WITH LOSS OF DAYTIME HEATING AS CONVECTION MEANDERS ABOUT WITHIN A
WEAKENING ZONE OF CONVERGENCE.

ELSEWHERE...ELEVATED CONVECTION MAY YET PRODUCE AN ISOLATED
LIGHTNING STRIKE NEAR THE NEW ENGLAND COAST...OTHERWISE INTERIOR
CONVECTION ACROSS THE CNTRL PLAINS MAY OCCASIONALLY GROW TO DEPTHS
DEEP ENOUGH FOR LIGHTNING DISCHARGE.

..DARROW.. 05/05/2011
