...FIRE WEATHER WATCH IN EFFECT THURSDAY AFTERNOON...

.DISCUSSION...
IT WILL BE RELATIVELY MILD OVERNIGHT AS THE RELATIVE HUMIDITY ONLY
EXPERIENCES POOR RECOVERY. WINDS FOR THE REST OF TONIGHT WILL BE
DRIVEN BY LOCAL DRAINAGE PATTERNS. HOWEVER...SOME GUSTY WINDS MAY
SURFACE OVERNIGHT AS THE INVERSION IS SHALLOW AND STRONG WINDS
EXIST AT THE BASE OF THE INVERSION. A COLD FRONT WILL APPROACH
AFTER MIDNIGHT...AND THIS WILL SWITCH WINDS TO THE NORTHWEST
BETWEEN 300 AND 400 AM THURSDAY. THE COMBINATION OF THE GUSTY
NORTHWEST WINDS...LOW RELATIVE HUMIDITY...AND DRY FUELS HAS
PROMPTED A FIRE WEATHER WATCH FOR THURSDAY AFTERNOON.
