NWS STORM PREDICTION CENTER NORMAN OK
1252 AM CDT MON MAR 24 2014

VALID 241200Z - 251200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
CONTINUED/GRADUAL AMPLIFICATION OF THE UPPER PATTERN ACROSS THE U.S.
IS FORECAST TO CONTINUE MONDAY/MONDAY NIGHT...AS ERN U.S. TROUGHING
STRENGTHENS WITH TIME IN RESPONSE TO SHORT-WAVE ENERGY DIGGING
RAPIDLY SEWD OUT OF CENTRAL CANADA ACROSS THE PLAINS AND EVENTUALLY
INTO THE MIDWEST/OH VALLEY. MEANWHILE...UPSTREAM RIDGING -- ALIGNED
ALONG THE W COAST EARLY -- IS FORECAST TO SHIFT INLAND WITH
TIME...AS AN UPPER LOW APPROACHES THE PAC NW COAST THROUGH THE
SECOND HALF OF THE PERIOD.

AT THE SURFACE...A COLD FRONT IS PROGGED TO LIE ACROSS THE GULF OF
MEXICO AND EWD INTO THE FL KEYS VICINITY EARLY IN THE
PERIOD...THOUGH WEAK CYCLOGENESIS INVOF THE FL PENINSULA MAY ALLOW
SOME MINOR NWD RETREAT OF THE BOUNDARY DURING THE AFTERNOON. DURING
THE SECOND HALF OF THE PERIOD...THIS FL LOW IS FORECAST SHIFT NEWD
AWAY FROM THE FL COAST AND DEEPEN AS IT MOVES ATOP THE GULF STREAM
THROUGH THE OVERNIGHT HOURS.

THE COLD FRONT -- AND LATER THE DEEPENING LOW -- WILL SUPPORT FAIRLY
WIDESPREAD CONVECTION...INITIALLY ACROSS FL DURING THE DAY AND THEN
LATER SPREADING NEWD ACROSS THE GA AND CAROLINA COASTAL REGIONS AND
ADJACENT WRN ATLANTIC. MEANWHILE FARTHER W...ELEVATED SHOWERS AND A
FEW THUNDERSTORMS ARE EXPECTED ACROSS PARTS OF S TX AS WELL AS THE
TX/LA COASTAL AREAS...AND EWD ACROSS THE GULF NEAR AND N OF THE
FRONT. IN ALL INLAND AREAS...CAPE/SHEAR COMBINATION SHOULD REMAIN
INSUFFICIENT FOR SEVERE CONVECTION THROUGH THE PERIOD.
