NWS STORM PREDICTION CENTER NORMAN OK
1224 AM CDT TUE MAR 10 2009
VALID 111200Z - 121200Z
...NO SVR TSTM AREAS FORECAST...
...SYNOPSIS...
BROAD UPPER TROUGH/STRONG UPPER JET WILL QUICKLY OVERSPREAD EASTERN
CANADA AND THE NORTHEAST STATES ON WEDNESDAY. WITH A SOUTHERN STREAM
UPPER LOW ADVANCING ALONG THE CA COAST...LOW AMPLITUDE
WEST-SOUTHERLY FLOW ALOFT WILL PREVAIL DOWNSTREAM ACROSS THE
SOUTHERN STATES AS AN EXTENSIVE COLD FRONT STEADILY SPREADS
SOUTH-SOUTHEASTWARD ACROSS TX AND THE LOWER MISSISSIPPI VALLEY.
...SOUTH CENTRAL TX/RIO GRANDE VICINITY...
SHOWERS/TSTMS WILL BE COMMON ALONG AND BEHIND/NORTH OF THE ADVANCING
SHALLOW COLD FRONT ACROSS TX...WHILE A CAP WILL LIKELY LIMIT
DEVELOPMENT IN THE PREFRONTAL WARM SECTOR. SUFFICIENT
SHEAR/INSTABILITY ALONG THE IMMEDIATE FRONTAL ZONE MAY SUPPORT AN
ISOLATED SEVERE HAIL THREAT ACROSS SOUTH CENTRAL TX/RIO GRANDE
VICINITY. HOWEVER...A SEEMINGLY LOW POTENTIAL AND UNCERTAINTY
REGARDING THE DIURNAL TIMING/MOVEMENT OF THE SHALLOW FRONT PRECLUDES
ANY SEVERE PROBABILITIES AT THIS TIME.
