DISCUSSION
ISSUED AT 127 PM EDT THU OCT 22 2026
A LARGELY STAGNANT SYNOPTIC PATTERN WILL ALLOW FOR MILD AND DRY
CONDITIONS TO CONTINUE LIKELY THROUGH THE END OF OCTOBER. UPPER
AIR OBSERVATIONS REVEAL A LARGE UPPER LEVEL RIDGE BUILDING OVER
THE CENTRAL CONUS THIS MORNING; AS IT GRADUALLY CONTINUES TO
BUILD, THE RIDGE WILL SHIFT EASTWARD IN THE COMING DAYS. AN
OMEGA BLOCK PATTERN IS LIKELY TO SETUP WITH SINKING AIR
UNDERNEATH THE RIDGE YIELDING LOTS OF SUN, MILD TEMPERATURES,
AND LIGHT WINDS. WITH AN EXPANSIVE AREA OF SURFACE HIGH PRESSURE
ALSO EXPECTED TO ANCHOR OVER THE EASTERN US, THIS PATTERN WILL
LIKELY REMAIN THROUGH THE WEEKEND INTO EARLY NEXT WEEK. EXPECT
SEVERAL DAYS OF RINSE AND REPEAT WEATHER WITH HIGHS IN THE UPPER
60S TO LOW 70S AND LOWS IN THE LOW TO MID 40S EACH DAY.
VERY FEW CHANGES WERE MADE TO THE FORECAST TODAY AS A PERSISTENCE
FORECAST WAS LARGELY UTILIZED THROUGH EARLY NEXT WEEK. NO RAINFALL
IS EXPECTED OVER THE NEXT 7 DAYS; IT IS STARTING TO BECOME EVIDENT
THAT WHILE A COLD FRONT MAY MOVE THROUGH AROUND NEXT TUESDAY, THERE
WILL NOT BE SUFFICIENT FORCING AND MOISTURE AVAILABLE FOR ANY
RAINFALL WITH IT. TOWARDS THE MIDDLE OF NEXT WEEK, TEMPERATURE
GENERALLY TREND TOWARDS NORMAL WITH HIGHS AROUND 60 DEGREES AS
THE AFOREMENTIONED SYNOPTIC PATTERN BREAKS DOWN.
WITH THE STAGNANT PATTERN LOCKED IN PLACE, CLEAR SKIES, AND LIGHT
FLOW WILL LIKELY YIELD SOME PATCHY DENSE FOG OVERNIGHT INTO EARLY
FRIDAY MORNING. BEST CHANCES FOR FOG WILL LIKELY BE NORTHEAST OF
FORT WAYNE, IN. MUCH LIKE THE PAST FEW NIGHTS, THE BEST TIMEFRAME
FOR DENSE FOG WILL BE BETWEEN 3 AM TO 10 AM EDT FRIDAY, WITH THE
LOWEST VISIBILITIES AROUND DAYBREAK. A SPS OR DENSE FOG ADVISORY MAY
BE NEEDED OVERNIGHT DEPENDING ON TRENDS AND WHERE ANY FOG
DEVELOPS.
