Oak Hill, WV (WOAY-TV): A moisture surge ahead of an approaching cold front will promote pockets of flooding Monday and Tuesday.
Each morning on Monday and Tuesday will begin with a few peaks of sun and only a small handful of light to briefly moderate showers from Route 19 to Route 219. During the afternoon and evening, additional showers will develop and under the core of these showers, expect rainfall rates of 1.5 inches per hour for a period of about an hour. This will result in flash flooding.
The increased moisture content is a result of Idalia’s moisture being pulled north (from the Gulf of Mexico) in the mid-levels of the atmosphere. If Idalia’s moisture was being pulled into southern West Virginia from the surface to the mid-levels, widespread flooding would be the result, but instead, we only expect scattered reports of flooding.
The best chance for flash flooding is the Greenbrier Valley, although a few heavier showers will create ponding of water on roads along the I-64 & 77, Route 19 and 460 corridors. Have the StormWatch 4 Weather App on hand in case a Flash Flood Warning is issued for your area.
Dense fog is likely each night through Wednesday morning.
Arthritis sufferers can expect moderate joint pain Tuesday into Wednesday before the pressure rises as Canadian high pressure moves into our region. A cold front promises a return to a cooler, drier air mass Tuesday night.
The western extent of the steady, heavy rain associated with Idalia will be focused across central North Carolina. Idalia will not have any direct impacts in southern West Virginia.
