VALID 281200Z - 291200Z

...SYNOPSIS...
CYCLONIC FLOW ALOFT WILL CONTINUE TO PREVAIL ACROSS THE U.S. THIS
PERIOD...THOUGH SOME EWD PROGRESSION OF THE UPPER PATTERN WILL ALLOW
LARGE-SCALE RIDGING TO SLIDE INTO THE WRN U.S. WITH TIME.

AT THE SURFACE...THE DAY 2 COLD FRONT WILL BE WELL OFFSHORE OVER THE
WRN ATLANTIC BY THE START OF THE PERIOD...LINGERING ONLY ACROSS FAR
S FL AND THE KEYS. WITH HIGH PRESSURE IN THE WAKE OF THE FRONT
USHERING COOL/DRY CONTINENTAL AIR SWD ACROSS THE ERN 2/3 OF THE
COUNTRY/EAST OF THE ROCKIES...THUNDER POTENTIAL IS VIRTUALLY NIL
WITH THE EXCEPTION OF S FL AND THE KEYS. EVEN HERE...WEAK LAPSE
RATES AND MODEST LOW-LEVEL FLOW PRECLUDE APPRECIABLE SEVERE
POTENTIAL THROUGH THE PERIOD.
