TORRID UPPER RIDGE WILL AMPLIFY A BIT FURTHER NEAR TERM BEFORE
FLATTENING ACROSS THE GREAT LAKES SOMEWHAT LATE WEEKEND. THIS
IN TURN SHOULD ALLOW FOR COMPOSITE OUTFLOW/COLD FRONTAL ZONE TO
SINK SEWD INTO AT LEAST NORTHWEST PORTIONS OF THE AREA LATER SUNDAY
NIGHT, PROVIDING CHANCES FOR TSTORMS THAT WILL THEN EXTEND
THROUGH MID WEEK TIMED WITH ACTIVE STORM TRACK THROUGH SRN
CANADA. HOTTEST TEMPS EXPECTED SAT - MON BENEATH HEART OF UPPER
RIDGE YET TEMPS EXPECTED TO CONTINUE WELL ABOVE NORMAL THROUGH
THE WEEK WITH REAMPLIFICATION OF UPPER RIDGE LIKELY AGAIN BY
NEXT WEEKEND. IN BETWEEN, PROXIMITY OF STALLED FRONTAL ZONE
IMPLIED ACROSS PARTS OF THE AREA SUPPORTS CHANCE POPS TIED TO
THE DIURNAL CURVE, MAINLY AFTERNOON AND EVENING.
AVIATION /18Z TAFS THROUGH 18Z SATURDAY/
ISSUED AT 123 PM EDT FRI AUG 8 2025
EXPECT PLENTY OF RIDGING ACROSS THE AREA, WHICH IS EXPECTED TO
PROVIDE PREVAILING DRY CONDITIONS. BCFG WAS NOTED AT FWA THIS
MORNING, BUT THEY STAYED MOSTLY IN VFR THROUGH THE MORNING HOURS
TODAY. FOG WILL LIKELY BECOME MORE SHALLOW TO GONE COMPLETELY AS WE
CONTINUE TO REMAIN DRY EACH DAY. AS SUCH, WILL PROVIDE VFR
CONDITIONS THROUGH THE PERIOD FOR BOTH TAFS. GENERALLY, SOUTH WINDS
PREVAIL AND 10 KTS SUSTAINED WILL BE POSSIBLE AT SBN THIS AFTERNOON
AND AGAIN TOMORROW SO ADDITIONAL GROUPS WILL BE USED TO HIGHLIGHT
THAT CHANGE.
