- QUIET WEATHER THIS WEEK
THE SURFACE HIGH THAT HAS DOMINATED THE WEATHER THE PAST FEW DAYS
SLOWLY MOVES EAST AND ALLOWS SOME MOISTURE RETURN IN SOUTHEAST
LOW LEVEL FLOW TODAY. WE WILL SEE ISOLATED AFTERNOON SHOWERS OR
THUNDERSTORMS AGAIN TODAY BUT THESE WILL ONCE AGAIN BE VERY
LIMITED WITH COVERAGE LESS THAN 10 PERCENT OF THE FORECAST AREA.
DEEP MOISTURE CONTINUES TO GRADUALLY INCREASE AS THE FLOW GOES
SOUTHERLY INTO THE WEEKEND. SHOWERS AND STORMS ALONG A WEAK
SURFACE TROUGH ARE POSSIBLE THURSDAY INTO FRIDAY, BUT UPPER
RIDGING SHOULD LIMIT COVERAGE OF ANY POTENTIAL CONVECTION.
MORE WIDESPREAD SHOWERS COULD BE IN THE OFFING FOR EARLY NEXT
WEEK AS A SHORTWAVE TROUGH FLATTENS THE HEAT RIDGE AND DRIVES A
COLD FRONT/SFC TROUGH THROUGH THE GREAT LAKES BY TUESDAY.
AVIATION /12Z TAFS THROUGH 12Z THURSDAY/
ISSUED AT 724 AM EDT WED AUG 6 2025

SOUTHEAST TO AROUND 10 KNOTS BY AFTERNOON.
MARINE
ISSUED AT 150 AM EDT WED AUG 6 2025
OFFSHORE WINDS WILL CONTINUE THROUGH TONIGHT WHICH WILL LIMIT

THE WEEKEND WITH WAVES SLOWLY INCREASING AS WELL.
