VALID 291200Z - 301200Z
...SYNOPSIS...
EAST COAST UPPER TROUGH IS EXPECTED TO MOVE TO THE WRN ATLANTIC
BASIN ON FRIDAY WITH THE ATTENDANT COLD FRONT MOVING THROUGH FL AND
THE GULF OF MEXICO. A FEW DIURNALLY-ENHANCED THUNDERSTORMS MAY
ACCOMPANY THIS FRONT IN FL. BUT...LAPSE RATES WILL REMAIN POOR AND
VERTICAL SHEAR WEAK AND SEVERE WEATHER IS NOT ANTICIPATED.
MEANWHILE...TO THE W...THE NEXT STORM SYSTEM WILL DIG TOWARD THE CA
COAST FRIDAY NIGHT. 00Z/27 ECMWF TIMING IS DECIDEDLY FASTER WITH
THIS SYSTEM COMPARED TO THE 00Z/27 GFS. THERE IS SOME CONCERN THAT
A BAND OF GUSTY THUNDERSTORMS MAY ACCOMPANY THE ARRIVAL OF THIS
IMPULSE ACROSS COASTAL CA AS SYSTEM TAPS 0.75+ INCH PWATS AND 80-90+
KT H5 JET APPROACHES THE REGION. HOWEVER...MODEL DIFFERENCES WILL
PRECLUDE THE ADDITION OF ANY SEVERE PROBABILITIES AT THIS TIME.
