FIRE WEATHER PLANNING FORECAST FOR SW VA...SE WV AND NW NC
NATIONAL WEATHER SERVICE BLACKSBURG VA
328 PM EDT TUE MAY 26 2015

.DISCUSSION...

HIGH PRESSURE OFF THE SOUTHEAST COAST WILL MAINTAIN A BROAD
SOUTHERLY FLOW OF DEEP MOISTURE INTO THE REGION THROUGH MUCH OF
THIS WEEK. AN UPPER LEVEL TROUGH OF LOW PRESSURE TO THE NORTHWEST
WILL GRADUALLY SLIDE EAST AND INTERACT WITH THIS MOISTURE ACROSS
THE AREA. THIS WILL RESULT IN PERIODIC ROUNDS OF SHOWERS AND
STORMS OVER THE NEXT FEW DAYS. INCREASING MOISTURE WILL ALSO
PROMOTE HIGHER HUMIDITY MINIMUMS COMPARED TO THE LAST SEVERAL DAYS
AND GREATER POTENTIAL FOR DEW FORMATION AT NIGHT.
