SHORT TERM /THROUGH THURSDAY/
ISSUED AT 421 PM EDT WED MAR 18 2026
AN UPPER TROUGH AXIS CONTINUES TO SIT ALONG THE EAST COAST, KEEPING
NORTHWEST FLOW OVER THE LOWER OHIO VALLEY. A SHORTWAVE IN THIS FLOW
CONTINUES TO PUSH THROUGH SOUTHERN INDIANA AND CENTRAL KENTUCKY AND
HAS CLEARED SKIES WEST OF INTERSTATE 65. EAST OF 65, DRY AIR IN THE
LOW LEVELS CONTINUES TO LIMIT MOST OF THE RAIN FROM REACHING THE
SURFACE. THROUGH THE REST OF THE AFTERNOON/EVENING, THIS CLEARING
AND SHOWERS WILL CONTINUE TO QUICKLY PUSH OFF TO THE EAST AS WINDS
BECOME LESS GUSTY.
TONIGHT, WITH SURFACE HIGH PRESSURE TO OUR SOUTHEAST AND LOW
PRESSURE TO OUR NORTHWEST, LIGHT SOUTH WINDS WILL LIMIT FALLING
TEMPERATURES TO THE MID 30S TO LOW 40S. MOST AREAS ARE EXPECTED TO
REMAIN ABOVE FREEZING.
TOMORROW, WITH THE OVERALL PATTERN REMAINING THE SAME, NORTHWEST
FLOW WILL PUSH ANOTHER SHORTWAVE THROUGH THE CWA DURING THE EARLY
AFTERNOON. THE FORECAST HAS TRENDED DRIER WITH THIS QUICK MOVING
SYSTEM. A SPRINKLE COULD BE POSSIBLE, BUT MANY WILL LIKELY NOT SEE
ANYTHING BESIDE SOME CLOUD COVER THAT IS EXPECTED TO CLEAR BEHIND
THE WAVE. WAA WITH CLEARING SKIES WILL HELP PUSH TEMPERATURES TO THE
MID 60S TO LOW 70S.
LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/
ISSUED AT 421 PM EDT WED MAR 18 2026
FRIDAY, A SURFACE LOW WILL GET PUSHED SOUTHEAST THROUGH THE
GREAT LAKES. THIS WILL PRODUCE A WEAK WEST-SOUTHWEST TO EAST-
NORTHEAST ORIENTED COLD FRONT WHICH WILL DROP SOUTH THROUGH THE
LOWER OHIO VALLEY. RAIN SHOWERS ARE EXPECTED EAST OF OUR AREA,
TOWARDS THE SURFACE LOW, BUT THIS COULD BRING SOME ADDITIONAL
CHANCES FOR LIGHT PRECIPITATION TO OUR EASTERN COUNTIES. WAA WILL
PUSH HIGHS INTO THE 70S WITH SOME UPPER 60S POSSIBLE IN THE
BLUEGRASS.
BY THE WEEKEND, HIGH SURFACE PRESSURE WILL CAUSE WINDS TO LIGHT AND
SOMEWHAT VARIABLE WITH BETTER CHANCES FOR EXTRA SUNSHINE.
TEMPERATURES CLIMB INTO THE 70S TO MID 80S.
SUNDAY NIGHT INTO MONDAY MORNING, A COLD FRONT IS EXPECTED TO DROP
SOUTH THROUGH THE REGION, DROPPING HIGHS BACK INTO THE LOW 50S TO
MID 60S EARLY NEXT WEEK. MULTIPLE MODELS SHOW A ROBUST STABLE LAYER
NEAR THE SURFACE, BUT SOME GUIDANCE HAS SOME ELEVATE INSTABILITY.
WITH THE BULK OF PRECIPITATION REMAINING TO OUR EAST, THIS FRONT
DOESN'T LOOK TOO CONCERNING. SOME ELEVATE INSTABILITY COULD LEAD TO
SOME HAIL, BUT THE WIND THREAT LOOKS LOW WITH A CHANCE WE CONTINUE
TO TREND DRIER.
AVIATION /18Z TAFS THROUGH 00Z FRIDAY/
ISSUED AT 210 PM EDT WED MAR 18 2026
AS A SHORTWAVE DROPS TO THE SOUTHEAST THROUGH THE LOWER OHIO VALLEY,
DRY AIR IN THE LOW LEVELS ARE CONTINUING TO KEEP AREA TAF SITES
MOSTLY DRY. CLEAR SKIES ARE QUICKLY PUSHING IN FROM THE WEST AND
HAVE ALREADY CLEARED HNB AND ARE NEARING SDF AND BWG. IN THE COMING
HOURS, CLEARING WILL CONTINUE AS WIND GUSTS EASE THIS EVENING. VFR
CONDITIONS ARE EXPECTED THROUGH THE REST OF THE PERIOD.
