KEY MESSAGES

CORRIDOR AND INTO NORTHWEST OHIO.
DISCUSSION
ISSUED AT 155 PM EDT SAT OCT 24 2026
STRONG UPPER-LEVEL RIDGING PERSISTS THIS AFTERNOON WITH SURFACE
HIGH PRESSURED NOTED OVER THE NORTHEAST. AS A RESULT, STATUS-
QUO ON THE FORECAST OVERALL INCLUDING CRUISE-CONTROL
TEMPERATURES WITHIN A COUPLE OF DEGREES THESE NEXT TWO DAYS.
WE'LL BE MONITORING FOR FOG TONIGHT INTO EARLY MONDAY MORNING.
GUIDANCE APPEARS MOST KEEN ON THE I-69 CORRIDOR INCLUDING
NORTHWEST OHIO, YET LIGHT SURFACE WIND FROM THE SOUTH MAY LIMIT
ANY LAKE ERIE MOISTURE ADVECTION, WHILE RADIATIONAL COOLING
APPEARS TO BE SUFFICIENT.
LOW PRESSURE OVER MANITOBA THIS AFTERNOON FEATURES A COLD FRONT
DRAPED ACROSS THE CENTRAL AND NORTHERN PLAINS. THIS FRONT ATTEMPTS TO
SEEP OVER OUR AREA TUESDAY AS IT GETS HUNG-UP ATOP OUR PERSISTENT
UPPER-LEVEL RIDGE. THIS WILL KNOCK TEMPERATURES DOWN A FEW DEGREES
TUESDAY, YET TEMPERATURES WILL STILL BE WELL ABOVE NORMAL (NORMAL
HIGH/LOW 60/40). OTHERWISE, REMAINING VERY MILD AND DRY THIS WEEK
WITH OUR NEXT CHANCE FOR ANY RAIN NOT ARRIVING UNTIL PERHAPS
THURSDAY AFTERNOON (20% CHANCE) AS ANOTHER FRONT ATTEMPTS TO CROSS
OUR RIDGE. THE ABUNDANCE OF DRY AIR AND OVERALL ABSENCE OF FORCING
LEAVES ME UNIMPRESSED. INSTEAD, LATE NEXT WEEKEND INTO EARLY
NOVEMBER LOOKS TO BE THE BETTER OPPORTUNITY TO END OUR DRY SPELL
WITH LOW PRESSURE EMERGING FROM THE SOUTHERN/CENTRAL PLAINS.
AVIATION /18Z TAFS THROUGH 18Z SUNDAY/
ISSUED AT 116 PM EDT SAT OCT 24 2026
ESSENTIALLY A BROKEN RECORD FOR THE FORECAST OVER THE NEXT 24
HOURS OR SO WITH THE MAJORITY OF THE PERIOD SEEING VFR
CONDITIONS AND THE ONLY SMALL WINDOW OF CHALLENGES FALLING
OVERNIGHT INTO SUNDAY MORNING. KFWA REMAINS THE SITE TO WATCH
FOR FOG AND/OR STRATUS CONCERNS. SIGNALS SUGGEST AT LEAST SOME
POSSIBLE MVFR VSBYS WITH SOME CHANCES FOR IFR/LIFR VSBYS AND
POSSIBLY CIGS 8 TO 14Z SUN. ONLY REAL CHANGE WAS TO ADD A TEMPO
FOR 3/4SM BR AND LET LATER SHIFTS FINE TUNE THE FORECAST. ANY
FOG/STRATUS HAS NOT BEEN BURNING OFF TILL 16Z-ISH SO WILL LEAVE
THE 3SM BR RUN THROUGH 18Z ALTHOUGH IT MAY VERY WELL BE OVERKILL
IN THOSE LAST HOURS.
