...DISCUSSION FROM PHXFWFPSR...



TEMPERATURES WILL REMAIN NEAR THE SEASONAL NORMAL WITH DRY 

CONDITIONS GIVING WAY TO A CHANCE OF THUNDERSTORMS OVER FAR EASTERN

DISTRICTS STARTING TUESDAY. MINIMUM HUMIDITY VALUES WILL  FALL INTO

A 15-30% RANGE FOLLOWING FAIR TO GOOD OVERNIGHT RECOVERY OF 30-70%.

OUTSIDE OF SOME OCCASIONAL LOCALIZED BREEZINESS DUE TO AN

APPROACHING SYSTEM, WINDS SHOULD RETAIN A TYPICAL  UPSLOPE/DRAINAGE

PATTERN OVER THE NEXT FEW DAYS



...THUNDERSTORMS IMPLY GUSTY WINDS...
