DISCUSSION
DRY WEATHER WILL CONTINUE TODAY, BUT LOW TO MEDIUM CHANCES
(20-40%) OF RAIN RETURNS LATE TONIGHT THROUGH SUNDAY AS A COLD
FRONT SWEEPS THROUGH THE REGION. MINIMUM RELATIVE HUMIDITY VALUES
ARE EXPECTED TO DIP INTO THE 30S FOR MOST AREAS THIS AFTERNOON.
THIS, IN ADDITION TO SUSTAINED SOUTHERLY WINDS AROUND 10 MPH
THROUGH THE AFTERNOON, MAY BE SOMETHING TO KEEP AN EYE ON; BUT,
FORTUNATELY, THIS DOES NOT MEET RED FLAG CRITERIA. WITH THE RETURN
OF RAIN CHANCES TONIGHT INTO SUNDAY, MINIMUM RH VALUES WILL THEN
INCREASE TO BE WELL ABOVE ANY CRITICAL THRESHOLDS. MIXING HEIGHTS
ARE EXPECTED TO REACH BETWEEN 1400-2800 FEET THIS AFTERNOON AND
1600-3900 FEET SUNDAY AFTERNOON. FURTHERMORE, SOUTHERLY TRANSPORT
WINDS WILL GENERALLY BE BETWEEN 15-20 MPH TODAY BUT SHIFT TO BE
NORTHEASTERLY AND RANGE BETWEEN 10-15 MPH ON SUNDAY. LASTLY,
GENERALLY GOOD DAYTIME DISPERSIONS TODAY ARE FORECAST TO BECOME
FAIR TO GENERALLY GOOD ON SUNDAY.
FOG POTENTIAL OVER THE NEXT FEW DAYS: NONE AT THIS TIME.
POTENTIAL FOR RED FLAG CONDITIONS: NONE AT THIS TIME.
