DAY 3 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0228 AM CST TUE DEC 01 2009
VALID 031200Z - 041200Z
...SYNOPSIS...
LARGE HIGH AMPLITUDE UPPER TROUGH TO REMAIN FIXED ACROSS MUCH OF THE
CONUS...AS AN UPPER LOW DRIFTS EWD INTO THE UPPER GREAT LAKES
REGION.
AT THE SURFACE...HIGH PRESSURE WILL EXPAND ACROSS MUCH OF THE LOWER
48...AS A COLD FRONT MOVES OFF EWD THE ATLANTIC COAST AND SWD ACROSS
THE GULF OF MEXICO AND THE SRN HALF OF THE FL PENINSULA THROUGH THE
PERIOD.
SHOWERS AND PERHAPS A FEW THUNDERSTORMS MAY LINGER THROUGH THE
MORNING ACROSS COASTAL NC...AND NWD INTO SRN NEW ENGLAND.
HOWEVER...ATTM IT APPEARS THAT APPRECIABLE SEVERE POTENTIAL OVER THE
ATLANTIC COAST REGION WILL HAVE MOVED OFFSHORE BY THE START OF THE
PERIOD.
SHOWERS AND STORMS WILL ALSO LIKELY LINGER ACROSS S FL AS THE FRONT
PUSHES SLOWLY SWD...BUT WITH WEAK LAPSE RATES AND VEERED/MODEST
LOW-LEVEL FLOW AHEAD OF THE BOUNDARY...SEVERE POTENTIAL APPEARS
SUFFICIENTLY LIMITED TO PRECLUDE THE INTRODUCTION OF ANY SEVERE
PROBABILITY ATTM.
