784 FXUS61 KRLX 231651 AFDRLXAREA FORECAST DISCUSSION National Weather Service Charleston WV 1251 PM EDT Tue Sep 23 2025
.SYNOPSIS... The chance for showers and thunderstorms continue through the work week as multiple disturbances affect the area. Conditions look to dry out some to end the week.
&&
.NEAR TERM /THROUGH WEDNESDAY/... As of 1220 PM Tuesday...
Most shower activity is now in the northeastern quadrant of the CWA, slowly continuing off to the north and east. Elsewhere, mostly overcast skies are noted, with some patchy breaks in the clouds, and overall more clouds than sun are expected over the CWA the rest of today. Shower activity will remain possible, but generally be subdued this afternoon and into the overnight hours. We collaborated with some neighbors to put in patchy fog across much of the area tonight. There is ample low-level moisture with the recent rains, but we could see it become more low stratus instead.
Heading into Wednesday, WPC does still have us under Slight risk (level 2 of 4) for the excessive rainfall outlook, though models still remain somewhat in flux on the timing and amount of rainfall we can expect. One thing that does seem a bit consistent across the near-term hi-res guidance is a signal of one slug of moisture that moves across the CWA in the morning. This is associated with the warm front pushing NE across the area as the surface low tracks over Ohio. Afternoon and evening showers are still expected across the area, but coverage and thunderstorm potential are more of a question mark as the morning activity may put a damper on further convection. However, if we can get some recovery in instability for the PM hours, SPC does have us under a Marginal risk (level 1 of 5) for severe weather, with damaging winds possible in any stronger thunderstorm cells.

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/... As of 1230 AM Tuesday...
An upper level low to our northwest will continue to push moisture and a frontal boundary into the area for Wednesday and Wednesday night. This will once again lead to numerous showers and thunderstorms. The front could act as a focusing mechanism for precipitation and with some areas already receiving rainfall and more expected today, there is some concern for flash flooding.
Models vary on where the cold front will stall Wednesday night into Thursday, but our region seems to be a prime target. The upper level low to our northwest will eventually evolve into a deep trough and start pushing eastward. This will push the cold front further eastward and east of our area Thursday or Thursday night.
The upper trough will push through the area on Friday, allowing for some showers behind the front.
&&
.LONG TERM /FRIDAY NIGHT THROUGH MONDAY/... As of 1230 AM Tuesday...
Models show that as the upper trough pulls away from the region, it leaves behind a cut off low over the southeast United States. Models vary on how far south of us the low is, with the Canadian being furtherest north and possibly affecting southern portions of our region. Some other models also leave some moisture over our mountains, which could lead to some showers. This leads to a lower confidence in the forecast for the weekend, especially for the southern and eastern portions of the forecast area.
&&
.AVIATION /18Z TUESDAY THROUGH SUNDAY/... As of 600 AM Tuesday...
Isolated to scattered showers/storms are expected today with a lull this evening going into Wednesday morning. Some brief restrictions to VIS under heavier shower activity is expected but should rebound quickly. CIGs may drop to MVFR during the late morning and through the afternoon, however will lift and scatter out slightly for the late afternoon and into the evening. MVFR CIGs will come back to the area early Wednesday morning.
Southwesterly flow will dominate and we could see gusty conditons during the afternoon at all sites, but nothing higher than 20kts, unless any site takes a direct hit from a storm.
FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z WEDNESDAY...
