411 PM EST TUE MAR 3 2009

FORECAST IS BASED ON IGNITION TIME OF 1000 EST ON MARCH 04.
IF CONDITIONS BECOME UNREPRESENTATIVE, CONTACT THE NATIONAL WEATHER
SERVICE.

.DISCUSSION...

A HIGH PRESSURE RIDGE AXIS WILL MOVE EAST OF THE AREA TONIGHT AND
ALLOW SOME SOUTHERLY FLOW TO RETURN TO THE AREA. THIS WILL ALLOW FOR
MUCH WARMER TEMPERATURES. THE BIG QUESTION IS HOW QUICKLY WILL THE
DEWPOINTS RECOVER WITH THE SOUTHERLY FLOW. IF THE CLOUDS DO NOT COME
IN AT ALL...THEN THE MIN RH WILL BE CLOSER TO 20 TO 25 PERCENT. BASED
ON THE EXPECTED CLOUD AND DEWPOINTS...THE MOST LIKELY MIN RH WILL BE 25
PERCENT.
