Area forecast discussion, Sep 20, 2:28 AM EDT, 2 hours 10 minutes before
Area Forecast Discussion National Weather Service Charleston WV 228 AM EDT Sun Sep 20 2026 .WHAT HAS CHANGED... No significant changes were made from the previous forecast package. && .KEY MESSAGES... 1) Unsettled through mid week amid a cooling trend with improving conditions for the end of the week and the weekend. && .DISCUSSION... KEY MESSAGE 1... Active weather will persist through today and past mid week. A frontal boundary will drape across the region and will meander through Monday while pushing slowly south and finally exiting by mid day Monday. This feature will provide chances for shower and storm activity and where a few storms could be strong to severe which should be isolated in nature. The main threat will be damaging wind. Much of the activity will be confined to the northern parts of our Country Warning Area where higher probabilities of precipitation exist. Another aspect is the area will be under an excessive rainfall outlook and the threat of heavy downpours amid thunderstorm activity will likely cause some instances of flash flooding to flood prone or low lying areas if hit repeatedly. This will be supported by anomalously high PWATs for this time of year. Once the feature exits a low pressure system digging and strengthening across the Great Lakes will come into the region and promote synoptic scale ascent to broaden the unsettled weather across our entire area. For much of Monday and Tuesday and even Wednesday will be under the influence of broad low pressure and chances for shower and thunderstorms. This is especially for Tuesday and Wednesday with high probabilities of precipitation especially during the daytime. This activity along with weak cold air advection will promote temperatures below seasonable starting Tuesday and continuing into the weekend promoting comfortable weather amid drier conditions as strong high pressure builds in for the the end of the work week and for the weekend. && .AVIATION /06Z SUNDAY THROUGH THURSDAY/... A very active morning with shower and thunderstorm activity possible at all sites. With calming flow at the surface some sites may endure fog development such as CRW through the morning. Enough cloud coverage, surface flow and convection should depress much development elsewhere, however there may be times at which a site decouples and fog may form temporarily or stay until 13/14Z. Or the other scenario is that shower activity will lower VIS and it may take a short while before lifting back to VFR. Thereafter, any low stratus will lift a few hours after the fog dissipates and VFR should prevail the rest of the TAF period. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 06Z MONDAY... FORECAST CONFIDENCE: Medium. ALTERNATE SCENARIOS: Restrictions and timing associated with fog will likely vary.Timing of showers/storms may vary from the forecast.

...STRONG THUNDERSTORMS WILL IMPACT GALLIA...JACKSON...LAWRENCE AND
NORTH CENTRAL CABELL COUNTIES THROUGH 515 AM EDT...
At 410 AM EDT, Doppler radar was tracking strong thunderstorms along
a line extending from 7 miles west of Jackson to near Franklin
Furnace. Movement was east at 25 mph.
HAZARD...Wind gusts up to 40 mph.
SOURCE...Radar indicated.
IMPACT...Gusty winds could knock down tree limbs and blow around
unsecured objects.
Locations impacted include...
Ironton, Jackson, Oak Hill, Rio Grande, Proctorville, Lake Vesuvius,
Barboursville, Gallia, Vernon, Waterloo, Aid, Crown City, Athalia,
Vinton, Hanging Rock, Adamsville, Mabee, Scottown, Pea Ridge, and
Petersburg.
This includes Interstate 64 in West Virginia between mile markers 16

PRECAUTIONARY/PREPAREDNESS ACTIONS...
If outdoors, consider seeking shelter inside a building.
Torrential rainfall is also occurring with these storms and may lead
to localized flooding. Do not drive your vehicle through flooded
roadways.
In hilly terrain there are hundreds of low water crossings which are
potentially dangerous in heavy rain. Do not attempt to travel across
flooded roads. Find alternate routes. It takes only a few inches of
swiftly flowing water to carry vehicles away.
