...DISCUSSION FROM RNOFWFVEF...

A LARGE AREA OF LOW PRESSURE WILL REMAIN OVER THE  PACIFIC NORTHWEST
THROUGH THE COMING WEEKEND WITH A DRY SOUTHWEST FLOW OVER THE
SOUTHERN GREAT BASIN AND MOJAVE DESERT. THIS WILL LEAD TO MOSTLY
CLEAR SKIES AND LOCALLY BREEZY CONDITIONS EACH AFTERNOON WITH
TEMPERATURES CLOSE TO NORMAL. WEDNESDAY WILL BE THE WINDIEST DAY
WITH GUSTS OVER 40 MPH EXPECTED OVER MUCH OF SAN BERNARDINO AND
MOHAVE COUNTIES. RELATIVE HUMIDITY VALUES WILL DROP TO THE SINGLE
DIGITS IN MOST AREAS EACH AFTERNOON.

 AFTERNOON AND EVENING IN THE MOUNTAINS AND DESERTS.  THIS TROUGH
WILL REMAIN IN PLACE THROUGH EARLY NEXT WEEK...WITH ONLY MINOR
