...DISCUSSION FROM PHXFWFPSR...



AFTER ANOTHER WARM AND DRY DAY TODAY, A MOSTLY DRY WEATHER SYSTEM

WILL DROP TEMPERATURES TO WELL BELOW NORMAL FOR FRIDAY AND INTO 

THE WEEKEND. WITH MINRHS BETWEEN 15-20% TODAY, WINDS WILL BECOME 

BREEZY AREAWIDE BY THE AFTERNOON WITH GUSTS MAINLY BETWEEN 20-25 

MPH. ACROSS SOUTHEAST CALIFORNIA, EXPECT LOCALLY WINDY CONDITIONS 

LASTING INTO TONIGHT WITH GUSTS AS HIGHS AS 35-45 MPH. BREEZY TO 

WINDY CONDITIONS WILL AGAIN IMPACT THE AREA ON FRIDAY WITH THE 

STRONGEST GUSTS TO AROUND 40 MPH ACROSS THE ARIZONA HIGH TERRAIN 

AND ACROSS IMPERIAL CO. MINRHS WILL IMPROVE STARTING FRIDAY, 

DIPPING TO BETWEEN 20-30% BEFORE LOWING BACK INTO THE TEENS OVER 

THE WEEKEND. THERE WILL ALSO BE A 20-30% CHANCE OF WETTING RAINS 

ACROSS THE ARIZONA HIGH TERRAIN LATE FRIDAY AND FRIDAY NIGHT.
