...SCATTERED SHOWERS AND STORMS TODAY...

.DISCUSSION...
AN UPPER LEVEL LOW TO THE SOUTH IS STILL SUPPLYING SUFFICIENT
MOISTURE AND INSTABILITY FOR SCATTERED SHOWERS AND THUNDERSTORMS
TODAY...SOME WILL BE STRONG WITH GUSTY WINDS...SMALL HAIL...AND BRIEF
HEAVY RAIN. WINDS WILL BE HIGHLY VARIABLE...BUT GENERALLY A
COMBINATION OF NORTHEAST PREVAILING FLOW ALONG WITH UPSLOPE. AS THE
LOW MOVES EAST TONIGHT AND THEN NORTHEAST TOMORROW...THE STRENGTH OF
THE STORMS WILL DIMINISH BUT THE COVERAGE OF SHOWERS WILL BE ABOUT THE
SAME AS TODAY. THIS MEANS IF YOU GET A SHOWER TOMORROW IT WILL BE
SHORTER-LASTING AND LESS INTENSE COMPARED TO TODAY. TODAY SHOWERS AND
STORMS ARE EXPECTED TO BE ONGOING IN THE BURN AREA AT IGNITION
TIME...THEN BECOME STRONGER AS WE MOVE INTO THE AFTERNOON.
