...SYNOPSIS...
A MID LEVEL SHORTWAVE TROUGH NOW OVER NW MEXICO...ALONG WITH THE
REMNANTS OF THE MID LEVEL LOW OVER NW TX...WILL MOVE EWD OVER THE
NRN GULF OF MEXICO/FL BY EARLY AFTERNOON TOMORROW.  THIS SYSTEM WILL
CONTINUE TO LOSE AMPLITUDE IN A CONFLUENT FLOW REGIME OVER THE
ATLANTIC COAST.  AT THE SURFACE...A COLD FRONT WILL ALSO MOVE SEWD
ACROSS THE FL PENINSULA.  A FEW THUNDERSTORMS WILL BE POSSIBLE
DURING THE DAY ACROSS S FL IN THE RESIDUAL WARM/MOIST SECTOR. 
DESPITE STRONG MID-UPPER WIND FIELDS WITH THE EJECTING TROUGH...
POOR MID LEVEL LAPSE RATES WILL LIMIT INSTABILITY AND THE THREAT FOR
SEVERE STORMS.

ANOTHER MID-UPPER TROUGH IS FORECAST TO GRADUALLY AMPLIFY OVER THE
SWRN STATES...THOUGH MOISTURE/LAPSE RATES SHOULD REMAIN INSUFFICIENT
FOR DEEP CONVECTION THIS AREA THROUGH TOMORROW.  OTHERWISE...A
CONTINENTAL POLAR AIR MASS WILL COVER THE CONUS E OF THE ROCKIES AND
PRECLUDE DEEP CONVECTION.
