CHARLESTON, W.Va. (WCHS/WVAH) — Some brief downpours with thunder crossed through our area today but they moved quickly and rainfall amounts were manageable on this Sunday. Unfortunately that will likely not be the case later this week or weekend. An active, fast-flowing jetstream pattern will lead to several waves of low pressure crossing through our area by the middle of the week and again for the weekend. The waves are weak but that means they won't cut as far north and west of us, leading to an extended period of heavy rain.
Scattered flurries/snow showers are likely Monday with afternoon temperatures mainly in the 30s. Most of Tuesday is likely ok during the day as well, but things will quickly get active Tuesday night as a warm front lifts north with a band of precipitation. Temperatures will be marginally cold enough at the onset that many of us could see a burst of wet snow develop around midnight Wednesday. Near and south of US 33 that should quickly transition to rain but farther north and especially in Southeast Ohio several inches of wet snow may accumulate into Wednesday morning's commute before changing to rain. Another area to watch for snow/sleet and freezing rain will be in eastern West Virginia.
Once we've gone to rain the focus will be on flooding as rainfall amounts of 1.5 to 3" appear likely Wednesday. Unlike the last few amounts where the highest amounts were in Ohio, this time around it appears West Virginia and Kentucky will see the higher totals and likely stream and creek flooding. Precipitation will taper but rivers like the Guyandotte, Kanawha, Coal and New will be on the rise through the end of the week. While we get a brief break it appears another wave will move in Saturday to Sunday with another round of heavy rainfall that will only exacerbate an already saturated ground. This could lead to even more widespread flood concerns for the weekend and possibly beyond.
Expect to see many Flood Watches issued in the coming days and eventually some inevitable Warnings. We'll be following the situation all week and will keep you updated with the latest information and safety reminders.
