KEY MESSAGES
UPDATED AT 235 PM EDT MON OCT 19 2026
- DRY WEATHER DOMINATES THE FORECAST PERIOD, WITH COOL MORNINGS
AND PLEASANT AFTERNOONS EACH DAY. AFTERNOON RELATIVE HUMIDITY
WILL REMAIN ON THE LOWER SIDE AS WELL.
DISCUSSION
ISSUED AT 235 PM EDT MON OCT 19 2026
WE WILL REMAIN ON THE EASTERN PERIPHERY OF AN ANOMALOUS UPPER LEVEL
RIDGE CENTERED ACROSS THE CENTRAL CONUS THROUGH THE PERIOD. A TROUGH
WILL ALSO TRANSLATE ATOP THE NORTHERN GREAT LAKES AND INTO THE NEW
ENGLAND REGION MID/LATE WEEK TO ASSIST IN MODERATING TEMPS TO ONLY
A FEW DEGREES ABOVE NORMAL LOCALLY. THE ASSOCIATED HIGH PRESSURE
AND SUBSIDENCE ALOFT WILL ALSO PROMOTE CLEAR SKIES AND DRIER AIR.
THESE DRY/CLEAR CONDITIONS WILL ALLOW FOR COOL MORNINGS BUT VERY
PLEASANT AFTERNOONS. THE FAVORABLE RADIATIONAL COOLING MAY ALSO
ALLOW FOR SOME PATCHY VALLEY FOG, AND PERHAPS ISOLATED FROST IN
SHELTERED VALLEYS ACROSS FAR NE TN/SW VA AND THE HIGHER TERRAIN
EACH MORNING AS WELL. OVERALL, A VERY COMFORTABLE WEATHER PATTERN
LACKING SIGNIFICANT IMPACTS FOR THE FORESEEABLE FUTURE.
AVIATION
(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.
