DAY 3 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0157 AM CST FRI MAR 07 2014
VALID 091200Z - 101200Z
...NO SVR TSTM AREAS FORECAST...
...SOUTH TEXAS...
NAM APPEARS TO BE THE OUTLIER REGARDING THE EVOLUTION OF UPPER
TROUGH AS IT DIGS SEWD ACROSS THE ROCKIES INTO THE GULF STATES.
LATEST GFS/ECMWF LAG CENTER OF UPPER LOW CONSIDERABLY WEST ACROSS
NRN MEXICO RATHER THAN AN OPEN POSITIVE TILTED TROUGH INTO LA/MS/AL
AT 84HR PER THE NAM. FOR THIS REASON IT APPEARS WEAK WARM ADVECTION
SHOULD LINGER ACROSS SOUTH TX AS A SFC WAVE IS INDUCED ACROSS THE
WRN GULF BASIN. WHILE ELEVATED BUOYANCY IS NOT EXPECTED TO BE THAT
GREAT...A FEW HUNDRED J/KG MUCAPE SHOULD RESIDE NEAR THE LOWER TX
COAST SUCH THAT LIGHTNING MAY ACCOMPANY THE STRONGEST ELEVATED
CONVECTION. SLOW MOVEMENT OF UPPER TROUGH SUGGESTS CONVECTIVE
THREAT MAY LINGER NEAR THE COAST BEYOND 84HR.
