SCATTERED RAIN SHOWERS MOVING THROUGH THIS MORNING, BECOMING MORE
ISOLATED IN THE AFTERNOON. CAN'T RULE OUT AN EMBEDDED STORM THIS
MORNING, BUT POTENTIAL IS 10% OR LESS. THERE IS POTENTIAL (20%
CHANCE) FOR A FEW NON-SEVERE STORMS TO DEVELOP FROM MID-AFTERNOON
THROUGH EARLY EVENING, WHICH COULD PRODUCE SMALL HAIL, LOCALLY
HEAVY RAIN RATES, AND ERRATIC WINDS IF THEY MOVE DIRECTLY OVER
THE FIRE AREA. FORECAST RAINFALL AMOUNTS ARE GENERALLY LESS THAN
0.25", BUT COULD BE LOCALLY 0.5-0.75" IF THUNDERSTORMS MOVE
DIRECTLY OVER THE FIRE AREA. GIVEN CLOUD COVER AND RAIN CHANCES

GUSTS OF 15-20 MPH THROUGHOUT THE DAY.

THE POTENTIAL IS ONLY 10-30%. ALSO EXPECT SOME FOG DEVELOPMENT
