KEY MESSAGES
UPDATED AT 103 PM EDT SAT OCT 24 2026

AND PLEASANT AFTERNOONS EACH DAY. AFTERNOON RELATIVE HUMIDITY

DISCUSSION
ISSUED AT 215 AM EDT SAT OCT 24 2026
PATCHY EARLY MORNING FOG POTENTIAL WILL CONTINUE OVER THE NEXT
SEVERAL DAYS, BUT MAINLY NEAR RIVERS AND LAKES.
WE REMAIN IN A PERSISTENT PATTERN OF A LARGE UPPER RIDGE CENTERED TO
OUR WEST AND SURFACE HIGH PRESSURE EXTENDING INTO OUR AREA FROM THE
NORTH AND NORTHEAST. THE RIDGE AXIS WILL SHIFT GRADUALLY EAST, AND
SHORT WAVE ENERGY MOVING THROUGH THE GREAT LAKES REGION WILL ACT TO
TEMPORARILY SUPPRESS THE RIDGE DURING THE MIDDLE OF NEXT WEEK.
HOWEVER, MODELS CONTINUE TO INDICATE WE WILL REMAIN DRY FOR THE
ENTIRE PERIOD THROUGH NEXT FRIDAY.
FOR THE ENTIRE PERIOD WE CAN EXPECT SEASONABLY COOL NIGHTS AND
PLEASANT AFTERNOONS WITH HIGH TEMPERATURES GENERALLY A LITTLE ABOVE
NORMAL FOR THIS TIME OF YEAR. WE WILL ALSO CONTINUE TO SEE LOW
RELATIVE HUMIDITY VALUES DURING THE AFTERNOON HOURS, BUT LIGHT WINDS
WILL HELP TO MITIGATE NOTABLE FIRE WEATHER CONCERNS.
