DISCUSSION
ISOLATED SHOWERS AND THUNDERSTORMS ARE EXPECTED THIS AFTERNOON AND EVENING,
WITH RAIN CHANCES DIMINISHING AFTER SUNSET TONIGHT. MOST SHOWERS AND STORMS
SHOULD PRODUCE BRIEF HEAVY RAINFALL AND LIGHTNING, WITH A FEW STRONGER STORMS
PRODUCING WINDS OF 40 TO 50 MPH AND SMALL HAIL, THOUGH THAT CHANCE IS LESS THAN
10% AT THE FORECAST SITE. OTHERWISE, SOUTHWEST WINDS SHOULD GRADUALLY DECREASE
THIS EVENING AND BACK TOWARD THE SOUTHEAST AFTER SUNSET. OUTSIDE OF STORMS,
MIXING SHOULD BE SUFFICIENT FOR GOOD DISPERSION VALUES, WITH DISPERSION VALUES
DECREASING LATER THIS EVENING AS A TYPICAL NIGHTTIME STABLE LAYER SETS UP.
TOMORROW, BREEZY SOUTH-SOUTHWEST WINDS ARE EXPECTED ONCE AGAIN WITH MIXING
BEING SUFFICIENT FOR GOOD TO EXCELLENT SMOKE DISPERSION. RELATIVE HUMIDITY VALUES
ARE EXPECTED TO FALL INTO THE LOW-TO-MID 40S IN THE AFTERNOON, THOUGH THIS IS
SOMEWHAT UNCERTAIN AS DEEPER MIXING MAY BE ABLE TO MIX DOWN SOME DRY AIR.
