You’ll wake up to another cool morning in Southwest Virginia on Tuesday, lots of 40s and low 50s, just how cool depending on how clear it stays at your location. The long, cool dry period we’re in may have something of an interruption on Wednesday, as a low tracks just south of our region. While there will be some heavier rain in states to our south, moisture will be running into high pressure and drier air aloft the farther north it goes. Much like a winter overrunning moisture setup, gauging just how far north the thicker moisture gets is difficult. For now, it looks like mostly light rain for our region, generally under a quarter-inch east of I-77 and a little more to the west. But this could change upward if the low is a little more vigorous or somewhat farther north than expected, bringing a richer flow of Gulf of Mexico moisture, or if it is weaker and farther south, or the high and dry air are a little more impenetrable than models show, which would lessen rain amounts. At the least, it appears easterly to southeasterly surface winds between the approaching low and high pressure to our northeast will bringing a cloudy, possibly drizzly day to much of our region on Wednesday, with highs maybe not getting out of the 60s for many. Dry weather returns after this brief interlude, with fall-like temperatures, 60s-70s highs, 40s-50s low, into the weekend, with maybe some chance of showers by Sunday and Monday as the front approaches.
