KEY MESSAGES
* WIDESPREAD FREEZING TEMPERATURES ARE EXPECTED AGAIN THIS
MORNING ACROSS THE REGION.

BRINGING WELL ABOVE AVERAGE AFTERNOON TEMPERATURES.
* COOLER TEMPERATURES AND UNSETTLED WEATHER, INCLUDING VALLEY
RAIN, MOUNTAIN SNOW AND GUSTY WINDS, RETURN BY MID-WEEK NEXT
WEEK.
DISCUSSION
DRY CONDITIONS, CLEAR SKIES AND GENERALLY LIGHT WINDS CONTINUE
EARLY THIS MORNING, WHICH WILL CONTINUE TO ALLOW RADIATIONAL
COOLING TO BRING TEMPERATURES DOWN TO THE FREEZING POINT AGAIN
THIS MORNING. SOME GUSTY WINDS REMAIN IN THE SIERRA CREST THIS
MORNING, BUT UP TO 30 MPH.
THE UPPER RIDGE REMAINS OVERHEAD WHICH IS THE MAIN FEATURE
ALLOWING FOR THESE COLD MORNINGS, BUT AS THE AXIS APPROACHES THE
GREAT BASIN, TEMPERATURES WILL START TO WARM UP. WELL ABOVE
AVERAGE TEMPERATURES (BETWEEN 10-20 DEGREES ABOVE NORMAL) ARE
EXPECTED BY SUNDAY THROUGH AT LEAST TUESDAY. THE EFFECTS OF THE
UPPER RIDGE START TO WANE BY WEDNESDAY AS ZONAL FLOW DEVELOPS
AHEAD OF AN UPPER TROUGH AND CLOSED-LOW TOWARDS THE WEST COAST.
MODEL SOLUTIONS ARE STARTING TO HAVE BETTER AGREEMENT ABOUT THE
WEDNESDAY INTO FRIDAY TIMEFRAME WITH AN UPPER TROUGH IN THE PACNW
AND A CLOSED-LOW OFF THE CA COAST, WITH OUR REGION IN THE
DEFORMATION ZONE BETWEEN THESE TWO SYSTEMS. THIS WOULD RESULT IN
AN INCREASE OF OUR RAIN AND HIGH ELEVATION MOUNTAIN SNOW CHANCES.
THERE IS STILL SOME UNCERTAINTY WITH THE TIMING AND PLACEMENT OF
THIS UPPER LOW. THEREFORE, ANY FURTHER DETAILS ARE TO BE
DETERMINED. AS WE LOOK INTO NEXT WEEKEND, THE CLOSED-LOW APPEARS
TO WOBBLE SOMEWHERE BETWEEN SOCAL AND THE EAST PACIFIC. THEREFORE,
WE COULD STILL OBSERVE CHANCES FOR VALLEY RAIN AND MOUNTAIN, BUT
CHANCES ARE QUITE LOW AT 10-30%.
