.DISCUSSION...

AN UPPER-LEVEL TROUGH IS MOVING ACROSS THE REGION THIS MORNING
WITH HIGH CLOUDS THAT HAVE CAUSED SURFACE TEMPERATURES TO HOLD
FAIRLY STEADY FOR THE PAST SEVERAL HOURS. THE ATMOSPHERE REMAINS
EXTREMELY DRY BELOW THESE CLOUDS AS INDICATED BY VIRGA ON THE
OUTER EDGE OF THE RADAR VIEW. TEMPERATURES THIS AFTERNOON SHOULD
RISE WELL INTO THE 70S FOR MUCH OF THE CWA WITH MILD NORTHERLY
LOW-LEVEL FLOW IN PLACE.

MID TO UPPER-LEVEL HEIGHTS WILL BEGIN TO RISE ON SATURDAY AS A
RIDGE STRENGTHENS TO OUR WEST. THIS WILL LEAD TO A WARMING TREND
WITH WIDESPREAD LOW TO MID 80S FOR HIGHS BEGINNING ON SUNDAY.
TEMPERATURES ARE EXPECTED TO CLIMB TO JUST A FEW DEGREES SHORT OF
RECORD LEVELS FOR MONDAY AS THE RIDGE AXIS SHIFTS EASTWARD.
SOUTHWESTERLY FLOW SHOULD CAUSE MOISTURE TO INCREASE BY TUESDAY
AND WEDNESDAY AS A FRONT APPROACHES FROM THE NORTHWEST. WITHOUT
MUCH IN THE WAY OF A FORCING MECHANISM...THE FRONT WILL SLOW ITS
FORWARD PROGRESSION. WITH FORWARD SPEED AND PLACEMENT OF THE FRONT
IN QUESTION...WILL CONTINUE TO SHOW BROADBRUSHED 20 POPS ACROSS
THE CWA FOR BOTH WEDNESDAY AND THURSDAY.
