VALID 271630Z - 281200Z
..NO SVR TSTM AREAS FORECAST...
THE UPPER LOW THAT HAD BEEN MEANDERING AROUND THE SCENTRAL U.S. MUCH
OF THIS PAST WEEK IS RAPIDLY BEING ABSORBED BACK INTO THE WESTERLIES
AS AN OPEN TROUGH. FROM ITS PRESENT POSITION OVER THE ERN OH/TN
VLYS IT WILL ACCELERATE NEWD ACROSS NEW ENGLAND EARLY TONIGHT. UPPER
TROUGH AND THE SFC COLD FRONT CURRENTLY LOCATED FROM ERN NY TO
DELMARVA IS PRECEEDED BY A STRONG SLY FLOW OF DEEP MOISTURE.
WHILE STRONG WIND FIELDS WOULD SUPPORT SOME SEVERE POTENTIAL AHEAD
OF THE COLD FRONT TODAY...THE WIDESPREAD CLOUDINESS/PCPN COUPLED
WITH WEAK LAPSE RATES PRECLUDES ANY THREAT. GIVEN MLCAPES EXPECTED
TO BE VERY LIMITED...GENERALLY LESS THAN 100 J/KG...EVEN ANY THUNDER
SHOULD MOSTLY BE CONFINED TO OFFSHORE WATERS WHERE MORE INSTABILITY
IS PRESENT.
