DISCUSSION
LIGHT SHOWERS CONTINUE OVER CENTRAL CALIFORNIA THIS EVENING IN
CONJUNCTION WITH LINGERING MOISTURE FROM THE FINAL WAVE OF THIS
WEEK'S WINTER SYSTEM. AS THE SYSTEM TRACKS EASTWARD OVER THE
GREAT BASIN IN THE COMING HOURS, STRONG MID-LEVEL WINDS UPWARDS
OF 60 KNOTS WILL TRACK COLDER AIR INTO THE REGION FROM THE
NORTHWEST. THIS COLDER AIR RESULTS IN A 50 TO 60 PERCENT
PROBABILITY FOR FREEZING TEMPERATURES FRIDAY MORNING FOR NON-
URBAN AREAS OF THE SAN JOAQUIN VALLEY WHICH WILL CONTINUE INTO
SATURDAY AND CAUSE A 70 TO 80 PERCENT PROBABILITY. EVEN COLDER
TEMPERATURES ARE EXPECTED FOR THE SIERRA NEVADA, WITH MINIMUMS
10 TO 20 DEGREES BELOW 6,000 FEET AND ZERO TO 10 DEGREES ABOVE
6,000 FEET.
THE STRONGER MID-LEVEL WINDS EXPECTED FOR THURSDAY NIGHT AND
FRIDAY MORNING WILL DESCEND TO THE SURFACE IN THE MOJAVE SLOPES
AS THE WINDS INTERACT WITH THE TEHACHAPI MOUNTAIN RANGE. SURFACE
GUSTS 40 TO 50 MPH REMAIN VIABLE OVER THIS TIME PERIOD, AND AS
SUCH, A WIND ADVISORY REMAINS IN EFFECT FOR THESE AREAS UNTIL 4
AM (INDIAN WELLS VALLEY, MOJAVE DESERT) AND UNTIL 10 AM (MOJAVE
SLOPES).
OVER THE WEEKEND AND INTO EARLY NEXT WEEK, A WARMING TREND WILL
TAKE HOLD WITH AFTERNOON TEMPERATURES NEARING SEASON NORMALS BY
MONDAY. THESE TEMPERATURES WILL HOLD THROUGH THE WEEK AS THE
NEXT SYSTEM MOVES INTO THE REGION. LATE MONDAY INTO TUESDAY, AN
AREA OF LOW PRESSURE WILL TRACK INTO THE PACIFIC NORTHWEST, WITH
A TROUGH EXTENDING SOUTHWARD FROM THE CENTER LOW. UPPER LEVEL
FLOW OVER CENTRAL CALIFORNIA WILL BE FROM THE SOUTHWEST AS A
RESULT, WITH ADDITIONAL PRECIPITATION EXPECTED FOR THE AREA.
HOWEVER, WITH WARMER AIR FROM THE SOUTHWEST, SNOW LEVELS HAVE
BEEN TRENDING UPWARD, NOW UPWARDS OF 9,000 FEET TUESDAY
AFTERNOON. THIS WILL RAISE CONCERNS FOR RUNOFF AND SNOW MELTING
BELOW THESE LEVELS.
