VALID 231200Z - 281200Z
..DISCUSSION
AN ARCTIC AIRMASS WILL SETTLE ACROSS MUCH OF THE CONUS EAST OF THE
ROCKIES ON DAYS 4-5/FRI-SAT. RESULTING STRONG HIGH PRESSURE AND
COLD/DRY/STABLE CONDITIONS WILL PERSIST OVER MUCH OF THE COUNTRY
THROUGHOUT THE PERIOD. HOWEVER, SOME THUNDERSTORM POTENTIAL COULD
DEVELOP ACROSS PORTIONS OF THE GULF COAST STATES/SOUTHEAST ON DAYS
4-6/FRI-SUN AS A SURFACE COLD FRONT PROGRESSES EAST/SOUTHEAST.
MODIFIED GULF MOISTURE WILL BE IN PLACE NEAR THE IMMEDIATE GULF
COAST. WARM ADVECTION IN THE LOW-LEVELS COULD RESULT IN ISOLATED
THUNDERSTORMS NEAR OR JUST TO THE COOL SIDE OF THE COLD FRONT FRIDAY
AFTERNOON ACROSS PARTS OF TX, SPREADING EAST/NORTHEAST ACROSS THE
SOUTHEAST THROUGH SATURDAY AND EARLY SUNDAY. INSTABILITY SHOULD
REMAIN WEAK AS BETTER MOISTURE REMAINS OFFSHORE, AND DUE TO
CONVECTION BECOMING UNDERCUT BY THE COLD FRONT.
