KEY MESSAGES
UPDATED AT 736 PM EDT MON AUG 3 2026
- SHOWER AND STORM CHANCES WILL CONTINUE EACH DAY THIS WEEK,
ESPECIALLY DURING THE AFTERNOON HOURS. A FEW LOCATIONS MAY SEE
VERY HEAVY RAINFALL WHICH COULD LEAD TO LOCALIZED FLOODING WITH
THESE SHOWERS AND STORMS.
- TEMPERATURES NEAR NORMAL TOMORROW AND ONWARD. NOT MUCH

DISCUSSION
ISSUED AT 235 PM EDT MON AUG 3 2026
OUR AREA FOR THE NEXT COUPLE OF DAYS WILL BE WEDGED BETWEEN
SURFACE HIGH PRESSURE TO THE NORTH AND WEST AND A STATIONARY FRONT
TO THE SOUTH AND EAST. BEHIND THE DEPARTING TROUGH OVER THE
NORTHEAST, A WEAK CUT-OFF LOW WILL CYCLE WHILE REMAINING TRAPPED
IN PLACE, WITH UPPER RIDGING TO THE WEST AND BROAD TROUGHING
ENCOMPASSING THE NORTHERN TIER OF THE COUNTRY.
DURING THE AFTERNOON AND EVENING HOURS, SHOWERS AND THUNDERSTORM
CHANCES WILL INCREASE ACROSS THE AREA, WITH THE HIGHEST
PROBABILITY OVER THE SOUTHERN APPALACHIANS. THE MAIN POSSIBLE
HAZARD IN PLACES IMPACTED WILL BE, LOCALIZED FLOODING UNDER A
HEAVIER STORM OR TRAINING AND WIND GUSTS. A MARGINAL RISK FOR
SEVERE STORMS WILL PRIMARILY BE EAST OF THE FORECAST AREA OVER
THE CAROLINAS TOMORROW. FORCING NEAR THE FRONT/LOW, PAIRED WITH A
VERY MOIST AND UNSTABLE AIRMASS WITH STEEPENING LAPSE RATES, MAY
LEAD TO WET MICROBURST POTENTIAL. THIS COULD BE POSSIBLE HERE
ALONG AND CLOSEST TO OUR EASTERN BORDER.
WEDNESDAY MAY BRING MORE WIDESPREAD CHANCES OF SHOWERS AND
THUNDERSTORMS ACROSS THE REGION, WHEN THE WEAK UPPER LOW IS
FORECAST TO BE ABSORBED BY THE AFOREMENTIONED BROAD TROUGH.
FOLLOWING THAT, MOSTLY UNCHANGED CONDITIONS THE REST OF THE WEEK
AND INTO THE WEEKEND WITHIN WEAK FLOW/STEERING, DIURNAL SHOWERS
AND THUNDERSTORMS, HUMID DAYS, AND NOT SO MUCH FLUCTUATING OF
TEMPERATURES.
