.DISCUSSION...

FEW OR NO FCST PRBLMS FOR TNGT WITH TEMPS DEWPTS AND WNDS LOOKING
REAL GOOD. WNDS WILL BEGIN TO DCRS SLWLY NEAR SUNSET BUT SHUD HOLD A
TOLERABLE BREEZE...NEAR 10 MPH...THRU LATE TNGT. SKIES SHUD STAY
PRETTY CLR AS CONVECTN POTENTL RMNS WELL TO THE N OF FCST AREA.
BETTER CU DVLPMNT FAR ERN PART OF FCST AREA MID AFTN BUT THESE SHUD

VSBYS IN BR BY DAYBREAK SUCH AS THIS MRNG AT SUX. KEEPING HEAT ADVY
THRU PD FOR NIGHTTIME WARMTH AND ALSO RED FLAG OUT W INTO ERY THIS
EVE ARE NO BRAINER DECISIONS. NOT TOO MUCH CAN HAPPEN TNGT OTRW.

PRETTY MUCH STATUS QUO FM PREV FCST WITH MINOR ADJUSTMENTS SUN INTO
EXTD BASED ON LATEST MODEL RUNS. NO PROBLEM WITH HEAT ADVY MAINLY
DUE TO EXTREME AFTN HEAT IN MIXED OUT DESERT WESTERN THIRD OF
CWA...AND HIGH HEAT AND HUMIDITY ERN TWO THIRDS OF CWA ALL THE WAY

MINIMAL CLDS. SLY WINDS SHOULD HOLD UP TEMPS AT NIGHT MAINLY IN
MIXED OUT HIGHER ELEVATIONS OF CWA...AND SOME RECORD HIGH MINS PSBL
THRU SUN NGT...AND SERN CWA MON NGT. OF COURSE MAIN PROBLEM IS
TIMING OF CDFNT SEWD OVER CWA TUE WHICH WILL DETERMINE TEMPS.
