...DISCUSSION...
SEVERE WEATHER IS NOT EXPECTED THROUGH FRI/D8.

AT THE BEGINNING OF THE PERIOD...AN UPPER TROUGH WILL BE SITUATED
OVER THE ERN STATES WITH GENERALLY DRY WEATHER. A DISTINCT SHORTWAVE
TROUGH IS FORECAST BY SEVERAL MODELS TO MOVE ACROSS THE SERN STATES
ON TUE/D5...WITH A COLD FRONT MOVING ACROSS FL DURING THE DAY.
ALTHOUGH SOME STORMS MAY OCCUR...THEY SHOULD BE WEAK WITH LITTLE
INSTABILITY.

IN THE WAKE OF THIS TROUGH...HIGH PRESSURE WILL RESULT IN OFFSHORE
FLOW ACROSS THE GULF OF MEXICO AND THE ATLANTIC...WITH LITTLE THREAT
OF STORMS.

BY FRI/D8...MODELS INDICATE A LARGE TROUGH AMPLIFYING ACROSS THE WRN
STATES. THIS WILL CREATE LOW PRESSURE ACROSS THE PLAINS...AND HELP
DRAW LOW LEVEL MOISTURE NWD. WHILE SEVERE WEATHER IS NOT EXPECTED
THROUGH D8...THE EVOLUTION OF THIS TROUGH WILL CONTINUE TO BE
MONITORED IN LATER OUTLOOKS.
