ANOTHER CHILLY MORNING THIS MORNING, BUT WITH SLIGHT IMPROVEMENT IN
READINGS BY A COUPLE OF DEGREES OR SO. DRY AIR AND CALM CONDITIONS
WILL ALLOW AREAS OF FROST FOR PARTS OF THE MOUNTAINS, PLATEAU, AND
NORTHEAST TN INTO SOUTHWEST VA AGAIN.
FOR THE WEEK AHEAD, LONGWAVE TROUGHING WILL REMAIN WELL INTO CANADA
WITH RIDGING POKING NORTH BETWEEN A CLOSED UPPER LOW OFF OF THE MID-
ATLANTIC AND ANOTHER CLOSED LOW OFF OF THE WEST COAST. THE WESTERN
LOW EVENTUALLY PHASES WITH THE MEAN FLOW, MEANWHILE THE ATLANTIC ONE
THAT WILL BRING COASTAL ISSUES TO PARTS OF THE EASTERN SEABOARD DUE
TO HARDLY ANY MOVEMENT, WILL BECOME ENVELOPED AND SHUNTED EAST
TOWARDS THE END OF THE WEEK. NO IMPACTS HERE EXCEPT PERSISTENT UPPER
LEVEL RIDGING AND SURFACE HIGH PRESSURE.
HIGHS BREAKING 70 RETURN FOR MUCH OF THE VALLEY LATER THIS
AFTERNOON. HIGHS WILL THEN REMAIN IN THE LOW TO MID 70S RANGE THE
REST OF THE FORECAST PERIOD INTO NEXT WEEKEND. A GENERAL
WASH/RINSE/REPEAT EACH DAY WITH LIGHT WINDS, MOSTLY SUNNY/CLEAR
SKIES, LOW HUMIDITY, AND NO PRECIPITATION FOR AT LEAST THE
FORESEEABLE FUTURE.

(18Z TAFS)
ISSUED AT 131 PM EDT MON OCT 19 2026
VFR CONDITIONS AND LIGHT WINDS PREVAIL AS HIGH PRESSURE DOMINATES
THE REGION. SOME PATCHY VALLEY FOG IS POSSIBLE IN THE MORNING,
HOWEVER, CONFIDENCE IN TERMINAL IMPACTS IS MUCH TOO LOW TO
INCLUDE ANY MENTION AT THIS TIME.
