=====FOGGY, WITH SPOTTY SHOWERS AND STORMS THIS AFTERNOON=====
A GAME OF CAT AND MOUSE IS ONGOING BETWEEN DEPARTING CLOUDS TO THE
EAST, AND APPROACHING LOW TO MID LEVEL CLOUDS FROM THE WEST. IN
AREAS THAT HAVE SEEN A FEW HOURS OF CLEARING, DENSE FOG IS FORMING.
TIMING AND FORECASTING HOW THICK THE FOG SETTLES IN IS TRICKY
BECAUSE FOG IS HARD TO FORM WITH ANY CLOUD COVER. BE THAT AS IT MAY.
A DENSE FOG ADVISORY WILL LIKELY BE ISSUED VERY SHORTLY TO ACCOUNT
FOR THE OBSERVED DENSE FOG IN SOME AREAS THAT AREN'T IN THE TYPICAL
VALLEY LOCATIONS, FAVORED IN AREAS FROM NEAR BOWLING GREEN TOWARDS
LEXINGTON AND PLACES NW FROM THERE, INCLUDING THE LOUISVILLE METRO.
THOUGH FOG MAY NOT BE QUITE AS PREVALENT AS A FEW NIGHTS AGO, IT
WILL NONETHELESS CAUSE CONCERN FOR DRIVERS IN THE MORNING.
BEYOND FOG, WINDS ARE LIGHT AS A COLD FRONT HAS NEARLY BISECTED OUR
CWA. NEARLY CALM WINDS ARE PRESENT ACROSS THE CWA, WITH GENERALLY
SOUTHERLY FLOW SOUTH OF AN EAST-TO-WEST LINE FROM JUST NORTH OF LAKE
CUMBERLAND TO JUST NORTH OF BWG. SPOTTY SHOWERS ARE BEGINNING TO
BUBBLE UP AND MOVE INTO OUR WESTERN CWA AS WELL. SPOTTY SHOWERS
CAN'T BE RULED OUT FOR THE REST OF THE MORNING. THIS SIGNIFIES THE
RETURN TO SW FLOW LATER THIS MORNING AND AFTERNOON AS A WARM FRONT
LIFTS THROUGH THE OHIO VALLEY TODAY. WARM MINIMUM TEMPERATURE
RECORDS MAY BE BROKEN LATER THIS MORNING CONSIDERING HOW SATURATED
WE ARE (I'D IMAGINE THE WHOLE CWA ONLY HAS THE CHANCE TO COOL BY
ANOTHER DEGREE OR TWO).
EVENTUALLY, AS THE WARM FRONT LIFTS THROUGH OUR AREA, IT WILL SLOWLY
RAISE CLOUD CEILINGS, SCOUR OUT FOG, AND GENERALLY PUSH LOWER POPS
TO OUR NORTH. SW FLOW MAY BE ENHANCED DUE TO THE CLOSE PRESENCE OF A
DEVELOPING LOW MOVING TOWARDS THE GREAT LAKES REGION. WHEN THE WARM
FRONT ASSOCIATED WITH THIS LOW PASSES TO THE NORTH, THERE MAY BE
ENOUGH INSTABILITY FOR STORMS TO FIRE AS IT PASSES SOMETIME AFTER 12
NOON EDT. FOR NOW, SINCE MOISTURE IS SO HIGH, AT LEAST IN THE LOWER
LEVELS, CLOUDS WILL BE RATHER SLOW TO CLEAR FOR PURE SUNSHINE BEFORE
STORMS FIRE. IN BETWEEN CLOUDS THOUGH, ENOUGH INSTABILITY COULD
PRESENT STRONG TO SEVERE WIND GUSTS. THE BEST WIND SHEAR WILL AVOID
US TO THE NW, AND AS A RESULT, THE TORNADO THREAT WILL LIKELY
COMPLETELY MISS OUR AREA. HIGHS WITH THIS ENHANCED SW FLOW BEHIND
THE FRONT WILL BE QUICK TO WARM THOUGH DESPITE THE MORNING CLOUD
COVER. THERE IS STILL A QUESTION OF HOW MUCH CLOUD COVER WILL STICK
AROUND THIS AFTERNOON BUT FOR NOW, HIGH TEMPERATURES SHOULD BE
WARMEST IN THE SOUTH (SOUTH OF I-64) IN THE MID TO UPPER 80S. NORTH
OF THE INTERSTATE, CLOUDS AND RAIN WILL TAKE THE LONGEST TO CLEAR
WITH HIGHS IN THE LOWER 80S TO UPPER 70S.
IT SHOULD BE SAID THAT DESPITE THE CHANCE FOR SEVERE WEATHER,
RAINFALL COVERAGE WILL BE SCATTERED AT BEST AND MOVE FAIRLY
PROGRESSIVELY WITH THE STRONG SW FLOW. ADDITIONAL RAINFALL TOTALS
HAVE A 75% OF REMAINING UNDER 0.5", WITH AN EXTREMELY ISOLATED RISK
OF UP TO 2" OF RAIN SHOULD A HEAVY DOWNPOUR OR TWO TRACK OVER THE
SAME AREAS THIS AFTERNOON. WE ARE NOT EXPECTING ANY FLASH FLOODING
CONCERNS TODAY AS THE BEST SEVERE RISK AND FLOODING RISK REMAIN TOO
FAR NORTH.
=====STRONG INCOMING COLD FRONT AND SEASONABLE WARMTH NEXT WEEK=====
SW FLOW WILL INTENSIFY AS THE IMPENDING COLD BEHIND THE DEPARTING
GREAT LAKES LOW GETS CLOSER AND SWEEPS THROUGH EARLY FRIDAY MORNING.
WINDS WILL INCREASE BY EARLY MORNING AND GROW STRONGER THROUGHOUT
THE DAY. TEMPERATURES WILL FALL INTO THE 60S FOR HIGHS AND COOLING
THROUGHOUT THE AFTERNOON AFTER FRONTAL PASSAGE WITH WIND GUSTS OF 25-
35 MPH.
SATURDAY, LOWS ARE CHILLY IN THE MORNING AS TEMPERATURES REALLY
STRUGGLE TO REACH THE UPPER 50S. THERE IS INCREASING CONFIDENCE IN
WIDESPREAD FROST SATURDAY NIGHT WITH CLEAR SKIES AND LOWS FORECAST
IN THE MID TO LOW 30S. WE WILL LIKELY ISSUE PRODUCTS RELATED TO
THIS WHEN THE TIME COMES.
BEYOND SATURDAY, HIGH TEMPERATURES VERY VERY SLOWLY MODERATE AS
HIGHS SUNDAY REACH THE MID 60S. ISOLATED FROST MAY BE POSSIBLE,
ALTHOUGH THE POSITIONING OF A HIGH PRESSURE MAY ALLOW WEAK SOUTHERLY
FLOW TO MODERATE US JUST ENOUGH TO STAY OUT OF FROST TERRITORY. LONG
RANGE TREND IS DRY, REALLY THROUGH THE REST OF THE WEEK.
TEMPERATURES LOOK TO REMAIN NEAR NORMAL EVENTUALLY SETTLING INTO THE
LOW 70S BY MIDWEEK NEXT WEEK.
AVIATION /06Z TAFS THROUGH 12Z FRIDAY/
ISSUED AT 147 AM EDT THU OCT 15 2026
FOG AND LOW LYING STRATUS BEHIND A COLD FRONT THAT HAS SETTLED JUST
NORTH OF BWG. VLIFR-LOW END MVFR NORTH OF THE FRONT WILL CONTINUE
THROUGH THE OVERNIGHT WITH CALM TO VERY LIGHT SOUTHERLY WINDS.
SHOULD FOG NEVER FORM IN SOME AREAS, LOW-LYING STRATUS WILL KEEP
CEILINGS BELOW MVFR. BWG MAY AVOID THE WORST OF THE CONDITIONS, WITH
SW FLOW REMAINING ALTHOUGH THE THREAT OF LOW-LYING STRATUS AND MVFR
IS STILL POSSIBLE. BY LATE MORNING ON THURSDAY, THE FRONT WILL LIFT
NORTH, SWITCHING WINDS OUT OF THE SW ACROSS ALL TERMINALS, CLEARING
FOG, AND GRADUALLY LIFTING CEILINGS FROM SOUTH TO NORTH. PROB30S
WERE INCLUDED FOR SHOWERS ACROSS TERMINALS, WITH MAYBE A STORM IN
THE AFTERNOON AT HNB. VFR RULES SHOULD RETURN TOMORROW AFTERNOON.
