AFTERNOON AND CONTINUING INTO MONDAY NIGHT AS A STORM SYSTEM LIFTS
THROUGH. SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS WILL BE A
GOOD BET DURING THIS PERIOD. THE POTENTIAL EXISTS FOR A FEW TENTHS
OF AN INCH OF PRECIPITATION LATER TODAY AND MONDAY IN THE EVENT A
SHOWER PARKS OVER THE BURN SITE. TEMPERATURES WILL BE COOLER AND
HUMIDITIES HIGHER...WHICH WILL BE A RESULT OF THICKER CLOUD-COVER.

STORM SYSTEM LOOKS TO COME BACK INTO THE AREA FOR NEXT WEEKEND.
