CONCERNS WITH STORMS THROUGH THIS EVENING. SCATTERED
SHOWERS/STORMS WILL REMAIN POSSIBLE TUESDAY AND WEDNESDAY BUT RAIN
CHANCES WILL GRADUALLY SHIFT SOUTH THROUGHOUT THAT TIME. AFTER
WEDNESDAY... FORECAST WILL REMAIN DRY.

TEMPERATURES WILL REMAIN GENERALLY BELOW NORMAL FOR THE NEXT FEW
DAYS AS COOLER AIR BEHIND THE FRONT AND CLOUD COVER CONTINUE TO
AFFECT THE FA. TEMPERATURES WILL WARM SOME OVER THE WEEKEND INTO
NEXT WEEK BUT STILL REMAIN AROUND NORMAL FOR THIS TIME OF YEAR.
