DAY 3 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0137 AM CST SUN JAN 09 2011
VALID 111200Z - 121200Z
...SYNOPSIS...
MODELS INDICATE THAT A LOW AMPLITUDE UPPER FLOW REGIME WILL PREVAIL
ACROSS THE U.S. DURING THIS FORECAST PERIOD...WITH RIDGING IN THE
WEST AND TROUGHING IN THE EAST. A STRONG AND INTENSIFYING MID/UPPER
JET STREAK IN THE BASE OF THE TROUGH IS PROGGED TO NOSE FROM THE
OZARK PLATEAU/TENNESSEE VALLEY THROUGH THE MID ATLANTIC COAST AND
ADJACENT WESTERN ATLANTIC...SUPPORTING STRONG CYCLOGENESIS NEAR
NORTHERN MID ATLANTIC AND SOUTHERN NEW ENGLAND COASTAL AREAS BY
EARLY WEDNESDAY. AT THE SAME TIME...A LARGE COLD SURFACE RIDGE TO
THE LEE OF THE ROCKIES IS EXPECTED TO CONTINUE TO BUILD SOUTHWARD
ACROSS THE GULF COAST INTO THE NORTHERN GULF OF MEXICO. WHILE WEAK
TO MODERATE BOUNDARY LAYER BASED DESTABILIZATION APPEARS POSSIBLE
TUESDAY AFTERNOON ACROSS THE SOUTHERN FLORIDA PENINSULA PRIOR TO THE
COLD FRONTAL PASSAGE ...WEAK MID/UPPER FORCING FOR UPWARD VERTICAL
MOTION AND LIMITED SHEAR PROBABLY WILL MINIMIZE THE CONVECTIVE
POTENTIAL...INCLUDING THE RISK FOR SEVERE STORMS.
