FIRE WEATHER PLANNING FORECAST FOR SW VA...SE WV AND NW NC
NATIONAL WEATHER SERVICE BLACKSBURG VA
349 PM EDT THU MAY 28 2015

.DISCUSSION...
A WEAK FRONTAL BOUNDARY WILL APPROACH THE AREA FROM THE NORTHWEST...
BUT IT WILL BE UNABLE TO DISLODGE THE WARM AND HUMID AIR
ENTRENCHED ACROSS THE REGION. THIS WILL KEEP SHOWERS AND
THUNDERSTORMS IN OUR FORECAST THROUGH THE END OF THE WEEK. HIGH
PRESSURE WILL BRIEFLY BUILD IN AND GIVE THE AREA A MOSTLY DRY
SATURDAY...BEFORE ANOTHER FRONTAL SYSTEM BRINGS SHOWERS AND
THUNDERSTORMS BACK TO OUR FORECAST FOR SUNDAY. COOLER AND SOMEWHAT
DRIER CONDITIONS WILL THEN BUILD IN FROM THE NORTH THROUGH THE
FIRST PART OF NEXT WEEK. MINIMUM RH VALUES ARE EXPECTED TO REMAIN 
ABOVE 50 PERCENT THROUGH THE PERIOD. MIXING HEIGHTS WILL REMAIN 
FAVORABLE BUT RELATIVELY LIGHT TRANSPORT WINDS WILL HINDER VENTILATION
RATES.
