..DISCUSSION FROM RNOFWFVEF
GUSTY WEST-NORTHWEST WINDS OF 25-35 MPH ARE LIKELY IN THE SOUTHERN
GREAT BASIN, NORTHERN INYO COUNTY, AND WESTERN SAN BERNARDINO
COUNTY TODAY. AFTERNOON RH VALUES ACROSS THE REGION GENERALLY
BETWEEN 20-40 PERCENT THROUGH SATURDAY, WITH OVERNIGHT RECOVERIES
45-70 PERCENT IN THE VALLEYS. MOISTURE INCREASES OVER THE WEEKEND
AS A SYSTEM BRINGS PRECIPITATION CHANCES TO ESMERALDA AND NORTHERN
INYO COUNTIES, BUT THE REST OF THE AREA REMAINS DRY.
..DISCUSSION FROM LAXFWFSGX
STRONGER WEST AND NORTHWEST WINDS THIS AFTERNOON AND EVENING WILL
CONTINUE OVER THE SAN BERNARDINO COUNTY MOUNTAINS AND HIGH DESERT
GUSTING TO 35 TO 45 MPH. HIGH TEMPERATURES WILL PEAK ON THURSDAY
WITH HIGHS 10 TO 20 DEGREES ABOVE NORMAL. THERE WILL BE A FEW
DEGREES OF COOLING WEST OF THE MOUNTAINS WITH MOUNTAINS AND DESERTS
REMAINING VERY WARM INTO FRIDAY. RELATIVE HUMIDITY VALUES WILL LOWER
NEAR 15-20% EACH DAY THROUGH FRIDAY. INCREASING HUMIDITY AND ONSHORE
FLOW WILL OCCUR BY THE WEEKEND INTO NEXT WEEK. AN AREA OF LOW
PRESSURE IS EXPECTED TO BRING WIDESPREAD RAIN CLOSER TO THE
CHRISTMAS HOLIDAY WITH WETTING RAIN CHANCES INCREASING BY LATER ON
TUESDAY INTO WEDNESDAY.
..DISCUSSION FROM PHXFWFPSR
PERSISTENT HIGH PRESSURE ACROSS THE REGION WILL RESULT IN WARM AND
DRY CONDITIONS INTO EARLY NEXT WEEK. HIGHS IN THE MIDDLE 70S TO THE
LOWER 80S WILL BE COMMON ACROSS THE LOWER DESERTS, OR 10 TO
15 DEGREES ABOVE DAILY NORMALS. WINDS WILL FOLLOW DIURNAL
