VALID 281200Z - 291200Z
..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
A FEW STRONG STORMS MAY OCCUR OVER PARTS OF THE CAROLINAS, AND
PERHAPS FROM WESTERN MONTANA INTO EASTERN WASHINGTON.
..SYNOPSIS
AN UPPER LOW WILL GRADUALLY WEAKEN AS IT MOVES VERY SLOWLY FROM CA
INTO NV ON THURSDAY, WITH A BELT OF STRONGER MID TO HIGH LEVEL WINDS
FROM UT INTO ID, WA AND OR, WHERE MINOR HEIGHT FALLS ARE EXPECTED
LATE. TO THE EAST, WEAK UPPER RIDGING WILL REMAIN OVER THE PLAINS,
WITH WEAK WINDS ALOFT. MEANWHILE, AN UPPER TROUGH WILL MOVE OUT OF
THE MID ATLANTIC, WITH WEAKENING NORTHWEST FLOW OVER THE CAROLINAS.
AT THE SURFACE, MOISTURE WILL REMAIN ABUNDANT FROM TX INTO THE
SOUTHEAST, SOUTH OF A COLD FRONT EXTENDING ROUGHLY FROM PARTS OF THE
MID/UPPER MS VALLEY TO SC. THIS BOUNDARY WILL PROVIDE A FOCUS FOR
AFTERNOON THUNDERSTORMS FROM NC INTO SC, BUT BOTH SHEAR AND
INSTABILITY ARE FORECAST TO REMAIN MARGINAL.
TO THE WEST, WEAK LOW PRESSURE WILL DEVELOP DURING THE DAY FROM
EASTERN WA INTO MT WITH STRONG HEATING. FORECAST INSTABILITY IS A
BIT UNCERTAIN THIS FAR OUT GIVEN THE PATTERN, THOUGH SOME MODELS
INDICATE HAIL POTENTIAL SHOULD SUFFICIENT MOISTURE DEVELOP INTO THE
REGION. DEEP LAYER SHEAR WILL BE FAVORABLE FOR CELLULAR DEVELOPMENT,
BUT PERHAPS A BIT SOUTH OF WHERE THE GREATER THUNDERSTORM
PROBABILITIES ARE. GIVEN THESE UNCERTAINTIES, WILL DEFER TO LATER
OUTLOOK UPDATES REGARDING ANY MARGINAL RISK POTENTIAL IN THE EASTERN
WA, NORTHERN ID, AND WESTERN MT AREA.
