A cold front is pushing through Virginia on this Thursday evening, but it won’t be all that cold as highs punch back into the 60s to near 70 on Friday and Saturday, two truly nice days of weather for outdoor activities in Southwest Virginia. Genuine cold air is on the way, though, as we’ve been noting, beginning with a sharper but likely dry cold front arriving by late Saturday. By Sunday, highs may not get out of the 50s for most in our region, and by Monday morning, many low temperatures could be in the upper 20s to mid 30s. Expect some frost and freeze advisories to go up for that. Yet another even deeper push of Arctic air arrives around the middle of next week, and the late week period may see a couple of days with highs in the 40s and lows in the 20s, especially west of Roanoke. (The map at left is a 6-10-day European model output of cumulative temperatures, with shades of blue representing intensity of cold relative to normal). These fronts pushing from the northwest will not be digging into much moisture, so rain chances look very limited into the foreseeable future. It would not be surprising, though, if upslope snow showers developed behind some of the cold fronts in the middle to latter part of next of week and beyond, as cold northwest winds lift moisture crossing the Appalachians. Warmth lifting far to the north in the Pacific to Alaska –partly connected to the remnants of Typhoon Wipha that hit Japan — is dislodging frigid Arctic air southward and southeastward into central and eastern North America. This general pattern may have 2-3 weeks staying power, so expect periodic cold air shots through that period.
