THE SLOW MOVING UPR LOW THAT TRAVERSED THE REGION EARLY THIS WEEK
HAS FINALLY MOVED OFF DOWNSTREAM OF THE AREA...WHILE ALSO LEAVING AN
A PIECE OF THIS DISTURBANCE IN A COMPACT UPR LOW OVER NORTHWEST
MEXICO. AT THE SAME TIME AN UPR RIDGE HAS BUILT JUST OFF THE WEST

THE WEST COAST...BRINGING DRY CONDITIONS AND WARMING TEMPERATURES. A
WEAK DISTURBANCE WILL BRIEFLY FLATTEN THE UPR RIDGE ON FRIDAY AS IT
MOVES ACROSS THE PACIFIC NORTHWEST...BUT THIS FEATURE IS EXPECTED TO
HAVE LITTLE IMPACT ON CONDITIONS ACROSS CA AND NV.
THE PEAK OF THE UPCOMING UPR RIDGE WILL BE ON MONDAY OR TUESDAY AS
AFTERNOON HIGH TEMPERATURES ARE EXPECTED TO PEAK ANYWHERE FROM PLUS
10- TO PLUS 20-DEGF OVER SEASONAL NORMALS...WITH A FEW LOCATIONS
OVER THE NORTHERN SIERRA AND NORTHWEST NV REACHING AN ANOMALY OF
PLUS 25-DEGF.
FREEZING LEVELS CURRENTLY BETWEEN 10500- AND 12500-FEET...GREATEST
