VALID 211200Z - 221200Z
..NO THUNDERSTORM AREAS FORECAST
..SUMMARY
THUNDERSTORMS ARE NOT EXPECTED ON FRIDAY.
..SYNOPSIS
ON FRIDAY A SPLIT-FLOW REGIME WILL EXIST WITH NORTHWEST FLOW FROM
THE NORTHERN PLAINS INTO THE GREAT LAKES, AND A STRONGER BELT OF
WESTERLY FLOW FROM THE SOUTHWEST INTO THE SOUTHEAST. THE OVERARCHING
THEME WILL CONTINUE TO BE STABLE CONDITIONS DUE TO HIGH PRESSURE
OVER THE CENTRAL AND EASTERN STATES, THOUGH SURFACE WINDS WILL
BECOME EASTERLY FROM THE BAHAMAS WESTWARD ACROSS THE GULF OF
AMERICA.
WHILE AN UPPER LOW IS FORECAST TO MOVE ACROSS AZ AND NM LATE IN THE
PERIOD, LITTLE INSTABILITY IS FORECAST WITH THIS SYSTEM AS IT DROPS
SOUTHEAST OUT OF THE FOUR CORNERS OVERNIGHT. GIVEN NOCTURNAL TIMING,
LACK OF HEATING AND MINIMAL DESTABILIZATION SUGGEST THUNDERSTORMS
WILL REMAIN UNLIKELY.
