DISCUSSION
BROAD HIGH PRESSURE WILL CONTINUE TO STRENGTHEN WHILE PUSHING
FURTHER OFFSHORE THROUGH MONDAY. SPOTTY SHOWERS AND THUNDERSTORMS
REMAIN POSSIBLE, ESPECIALLY WEST OF THE BLUE RIDGE THIS AFTERNOON
AND AGAIN FOR THE START OF THE WORKWEEK AS MULTIPLE PIECES OF
ENERGY PIVOT THROUGH. A STRONG COLD FRONT WILL BRING MORE
WIDESPREAD SHOWERS AND STRONG THUNDERSTORMS TO THE AREA WEDNESDAY
INTO WEDNESDAY NIGHT. BEHIND THIS SYSTEM, TEMPERATURES COOL WITH
CONTINUED RAIN CHANCES INTO THE WEEKEND AS THE FRONT STALLS
NEARBY.
MINIMUM RELATIVE HUMIDITY VALUES WILL FALL INTO THE 25 TO 35
PERCENT RANGE DURING THE AFTERNOON HOURS EARLY NEXT WEEK, ALONG
WITH HIGH TEMPERATURES WELL INTO THE 90S. THIS WILL BE ACCOMPANIED
BY 15 TO 20 MPH SOUTHERLY WINDS EACH AFTERNOON.
RAINFALL AMOUNTS THROUGH TUESDAY WILL REMAIN LESS THAN A TENTH OF AN
INCH FOR MOST, BUT ANY SPOT THAT MANAGES TO GET A STORM WOULD
LIKELY SEE MORE.
