WEDNESDAY: Today is a FIRST ALERT WEATHER DAY because of the flash flooding potential heading into Wednesday evening. Breezy with occasional gusty winds into the evening. Warm and very humid, feeling tropical before sunset. As the cold front crosses this evening this will drive the strongest line of rain and storms. Temperatures will be cooling quickly from southwest (after 6/7pm) to northeast (after 8/9 pm).

With any storm there will be torrential rain and gusty winds.

There is a severe threat but it’s a low threat. This would be for the early evening hours. An isolated instance of damaging winds is possible and there is enough wind shear in place for a possible brief tornado. The much bigger threat is flash flooding.

Because of the long duration of the rain the flooding threat will be limited. However there can still be a few instances of localized flooding especially in flood prone spots or near smaller creeks. Also in addition to where the heaviest bands of rain set up, where we have persistent storms. Rainfall from Tuesday through tonight is expected to be widespread 1-3″ with a few locally higher amounts especially in any storms. These localized higher amounts can top 4-5″.

With such a strong system, high moisture content and the fact that terrain can enhance rainfall amounts, it’s possible that along the mountains (Shenandoah, Great North, Blue Ridge mountains) rainfall may be around or surpassing 6″. This can lead to a greater risk of flash flooding because that water drains into smaller creeks and the rivers. Use extreme caution while driving Wednesday night. Flash flooding is much more dangerous at night when you may not be able to see. If you encounter water on the road, do not drive into it. You would be risking your life. Most flooding related deaths happen in vehicles.

Rain and thunderstorms will continue into the evening and overnight. Storms will drop torrential rain in some areas. Temperatures staying in the 60s for most of the night.

Rain tapers off as soon as the front pushes east of the Blue Ridge. This may be as early as 3/4 am Thursday morning, drying from west to east. As late as 7-9 am. Showers Thursday morning are dependant on how fast the front can push though.

By Thursday morning temperatures will be in the upper 50s for our West Virginia locations. Low 60s for the Valley.

THURSDAY: A pleasant morning with temperatures rising into the 60s. Rain early Thursday is dependant on how fast the front can clear, drying out from west to east. Skies clearing for the afternoon. Very comfortable as humidity drops. Highs in the mid to upper 60s for our West Virginia locations. Around 70/low 70s for the Valley. Smaller creeks will still be running high even after the rain stops and the ground will be quite muddy. Overall a nice afternoon as we dry out.
