DISCUSSION
 
 
THE COMBINATION OF A WEAK COLD FRONT TO THE NORTHWEST AND A VERY  
MOIST ATMOSPHERE WILL BRING THE POTENTIAL FOR SCATTERED TO PERHAPS  
NUMEROUS SHOWERS AND STORMS EACH AFTERNOON. GOOD WETTING RAINS ARE  
POSSIBLE FOR AREAS THAT DO SEE PRECIPITATION. THE HIGH DEWPOINTS WILL  
KEEP MIN RH VALUES AROUND 60-65 PERCENT EACH AFTERNOON. MIXING HEIGHTS  
AROUND 7-8 KFT SUNDAY AND 4-5 KFT MONDAY AND TUESDAY, ALONG WITH  
SOUTHERLY TRANSPORT WINDS OF 10-15 MPH WILL CREATE GENERALLY GOOD  
TO FAIR DISPERSION VALUES EACH DAY.  
 
FOG POTENTIAL OVER THE NEXT FEW DAYS: PATCHY FOG WILL BE POSSIBLE LATE TONIGHT  
INTO EARLY SUNDAY MORNING  
 
POTENTIAL FOR RED FLAG CONDITIONS: NONE AT THIS TIME.
