172 FXUS61 KRLX 040711 AFDRLXAREA FORECAST DISCUSSION National Weather Service Charleston WV 311 AM EDT Sat Oct 4 2025
.SYNOPSIS... Tranquil weather prevails into the start of next week courtesy of high pressure. A cold front slated to arrive on Tuesday brings the next chance of rain.
&&
.NEAR TERM /THROUGH TONIGHT/... As of 310 AM Saturday...
River valley fog has been forming across portions of the area and will continue to expand in coverage prior to sunrise. Fog should then erode from the area by mid-morning.
Another warm, dry day will materialize as high pressure remains in control of the Mid- Atlantic region beneath a staunch upper level ridge. After a cool morning, temperatures will rise above normal during the day with highs projected to reach mid 60s to low 80s in the mountains and upper 70s to mid 80s in the lowlands. Temperatures cool back down into the 40s to 50s overnight, with calm, clear conditions paving the way for more fog to develop in the river valleys before sunrise on Sunday.
&&
.SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/... As of 310 AM Saturday...
Quiet and dry weather is expected to continue through the beginning of the work week despite a gradual eastward shift of upper level ridging. Moisture then starts to increase as high pressure recedes from the area late Monday into Monday night.
Temperatures remain warmer than normal for this time of year with daily highs expected to be in the 80s in the lowlands and upper 60s to low 80s in the mountains. Overnight lows should range from near to above normal during the short term forecast period, with 40s to 50s expected for Sunday night and then 50s to low 60s Monday night.
&&
.LONG TERM /TUESDAY THROUGH FRIDAY/... As of 310 AM Saturday...
Precipitation chances spread into the area as moisture continues to increase ahead of a cold front Tuesday morning, then persist as the front passes across the area Tuesday night into Wednesday. Thunderstorms are also likely to occur in conjunction with the frontal passage, with activity quickly tapering off in its wake.
Drier conditions return with high pressure passing to the north on Thursday; thereafter, the forecast becomes less certain as some models remain dry while others suggest the arrival of a shortwave at the end of the work week.
Temperatures return to normal following the departure of the front and then remain seasonable through the end of the week.
&&
.AVIATION /06Z SATURDAY THROUGH WEDNESDAY/... As of 120 AM Saturday...
VFR conditions are expected to deteriorate as fog develops in the river valleys overnight, with EKN, CRW, and PKB being the most likely terminals to experience IFR or worse CIGs/VIS before sunrise. Conditions will gradually improve as fog lifts between 12-14Z. High pressure will then sustain VFR conditions for the rest of the TAF period.
Winds will be calm to light and variable for most of the TAF period.
FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 06Z SUNDAY...
