DISCUSSION
UPPER LEVEL RIDGING WILL CONTINUE TO PROMOTE A PROLONGED WARMING AND
DRYING TREND THROUGHOUT THE WEEKEND AND INTO NEXT WEEK. HIGH

80 DEGREE SPOTS IN THE DEEPER BASIN, AROUND 10 DEGREES WARMER THAN
NORMAL FOR THIS TIME OF YEAR. LOW TEMPERATURES WILL ALSO REMAIN
NEARLY 10 DEGREES WARMER THEN NORMAL. STARTING SUNDAY AND CONTINUING
THROUGH MONDAY, THE RIDGE WILL STRENGTHEN, INCREASING TEMPERATURES
BY ANOTHER 4-6 DEGREES WITH HIGHS IN THE HIGH 70S TO LOW 80S. ON
MONDAY, A WEAK DISTURBANCE WILL MOVE THROUGH, FLATTENING THE RIDGE
AND RESULTING IN AFTERNOON WIND GUSTS 10-15 MPH THROUGHOUT THE
REGION WITH LOCALLY HIGHER WIND GUSTS NEAR 20 MPH. THE FLATTENING OF
THE RIDGE WILL ALSO RESULT IN TEMPERATURES DROPPING A FEW DEGREES,
BUT WILL REMAIN AROUND 10 DEGREES HIGHER THAN NORMAL THROUGH
THURSDAY. ON FRIDAY, LONG RANGE MODELS SHOW A COLD FRONT MOVING
THROUGH, BRINGING A CHANCE FOR GUSTY WINDS THROUGHOUT THE BASIN
ALONGSIDE A CHANCE FOR RAIN SHOWERS. SHOULD THIS FRONT MOVE THROUGH,
MODELS DEPICT A NEARLY 10 DEGREE DECREASE IN TEMPERATURES FROM
FRIDAY TO SATURDAY, MUCH CLOSER TO NORMAL FOR THIS TIME OF YEAR.
