While the greatest threat for severe weather and greatest risk for widespread heavy rain will pass well northwest of our region, a cluster of showers and storms with some heavy rain has developed along the I-77 and I-81 corridors in Southwest Virginia and is moving northeast through the New River Valley this evening. The heaviest activity is likely to be primarily west of I-81, but some of it may slip eastward into the areas along the Blue Ridge and into the Roanoke Valley as well. This is being caused by an upper-level impulse slipping northeastward through West Virginia. We’re catching the southern fringe of its influence, but that could be enough for some localized flooding with heavier downpours this evening. A localized severe wind gust can’t be ruled out entirely, either. There could be additional rounds of showers and storms overnight and into Saturday before a cold front clears the region by evening. Sunday still looks to be somewhat cool (60s highs, 40s lows) but mostly clear day for Mother’s Day, and we could be dealing with some frost and possibly freezing temperatures, especially west of Roanoke, by Monday and Tuesday mornings. And then it could be 80 again by Wednesday afternoon. Jump on the spring roller-coaster, with a few rumbles and some splashes along the track this evening.
