617 FXUS61 KRLX 071719 AFDRLXAREA FORECAST DISCUSSION National Weather Service Charleston WV 119 PM EDT Sun Sep 7 2025
.SYNOPSIS... High pressure rules the roost today into much of the new week, yielding a stretch of dry weather, and gradually warming temperatures.
&&
.NEAR TERM /THROUGH MONDAY/... As of 1238 PM Sunday...
Surface high pressure overhead tonight, with cool and calm conditions, and fog developing overnight, particularly in favored river valleys. After fog burns off Monday morning, looking at a sunny dry day, with high temperatures generally in the 70s across much of the area. With the dry airmass in place, afternoon relative humidities look to dip into the upper 20s to lower 30s. Light surface winds and recent rains should keep any fire weather concerns at bay for the most part.
&&
.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/... As of 1238 PM Sunday...
Surface high pressure shifts east Monday night into Tuesday with continued dry conditions, and a gradual warm up in temperatures during the short term period. Afternoons will continue to be characterized by low RH, but winds look to remain generally light during the period. River valley fog will be possible overnight/early mornings during the period.
&&
.LONG TERM /THURSDAY THROUGH SATURDAY/... As of 1238 PM Sunday...
Dry weather looks to continue in the long term. A weak disturbance passing along our western border Thursday could produce a few sprinkles, but main effect should just be a slight uptick in cloud cover. Otherwise, with upper ridge nudging east into our area as we round out the extended, temperatures will rebound back to seasonal levels.

VFR with light surface winds through 06Z Monday when LIFR/VLIFR river valley fog is expected to develop. Fog will dissipate after 13Z with a return of VFR conditions with light surface winds.
