...SYNOPSIS...
AN AMPLIFIED UPPER TROUGH WILL MOVE QUICKLY EWD ACROSS THE GREAT
LAKES DURING THE DAY WITH A COLD FRONT SITUATED ACROSS CNTRL NY AND
PA AT 00Z. WHILE A FEW WEAK STORMS WILL BE POSSIBLE...MOISTURE AND
INSTABILITY WILL BE LIMITED DUE TO HIGH PRESSURE ACROSS MUCH OF THE
CNTRL AND SERN STATES...AND SEVERE WEATHER IS UNLIKELY.

ELSEWHERE...A WEAK UPPER TROUGH AXIS WILL EXIST FROM SRN AZ/NM INTO
PORTIONS OF THE SRN PLAINS...WITH AREAS OF RAIN. SOME RELATIVELY
HIGHER INSTABILITY LEVELS WILL EXIST FROM ERN TX INTO AR AND LA DUE
TO POCKETS OF MID 60S F DEWPOINTS...BUT LACK OF FORCING AND WEAK
FLOW SHOULD ONLY RESULT IN WEAK STORMS.
