...SYNOPSIS/FORECAST...
A STABLE CP AIR MASS HAS SPREAD OVER MOST OF THE COUNTRY DURING THE
PAST COUPLE OF DAYS.  A COLDER SURGE OF ARCTIC AIR MOVING INTO THE
SRN PLAINS WILL CONTINUE SWD INTO CNTRL TX BY EARLY THU AS A STRONG
UPPER IMPULSE TURNS EWD FROM THE CNTRL ROCKIES INTO THE CNTRL PLAINS
STATES.  DOWNSTREAM FROM THIS EVOLVING UPPER LOW...A RIDGE WILL
BUILD ACROSS THE SERN STATES...WITH A BROAD ZONE OF WEAK WARM/MOIST
ADVECTION DEVELOPING ALONG THE GULF COAST FROM E TX TO FL.

POLAR FRONTS HAVE RECENTLY PENETRATED WELL S INTO THE GULF OF
MEXICO.  DESPITE A SLIGHT INCREASE IN THE SLY LOW-LEVEL FLOW OVER
THE CNTRL/SRN GULF BASIN AND THE EXPECTED WEAK CYCLOGENESIS IN THE
WRN GULF...ANY MEANINGFUL INSTABILITY WILL REMAIN WELL OFFSHORE. 
THIS WILL PRECLUDE TSTM PROBABILITIES OVER THE ADJACENT COASTAL
AREAS THROUGH THE DAY 1 PERIOD.
