TODAY SHOULD BE MOSTLY SUNNY WITH SOME CLOUDS BUILDING IN THIS
AFTERNOON. THERE IS A SLIGHT CHANCE FOR SOME SHOWERS AND
THUNDERSTORMS TO DEVELOP THIS AFTERNOON INTO THE EARLY EVENING.
ACTIVITY WILL BE WIDELY SCATTERED AND NOT EVERYWHERE WILL SEE RAIN
FROM THIS POSSIBLE PRECIPITATION, BUT IF A THUNDERSTORM DOES
IMPACT THE SITE DIRECTLY, 0.1-0.25" OF RAIN IN A QUICK DOWNPOUR IS
POSSIBLE. MORE LIKELY ACCUMULATIONS ARE LESS THAN A TENTH OF AN
INCH. WHILE ANY THUNDERSTORMS THAT DEVELOP ARE NOT EXPECTED TO BE
SEVERE, BRIEF GUSTY ERRATIC WINDS, LIGHTNING, AND SMALL HAIL ARE
POSSIBLE HAZARDS. WE SHOULD SEE HUMIDITY SLIGHTLY HIGHER TODAY,
DROPPING TO AN AFTERNOON MINIMUM AROUND 35% WITH AN AFTERNOON HIGH
TEMPERATURE IN THE MID TO HIGH 80S. IF NO THUNDERSTORMS DEVELOP
AND HUMIDITY IS SLOWER TO MOVE IN THAN FORECAST, RH COULD DROP AS
