Record highs for March 22 and 23 are likely to be challenged at Roanoke and Blacksburg. We are likely to see more sunshine than Wednesday as a weak upper-level disturbance shifts southeast and high pressure becomes more entrenched. Those records for Roanoke are 84 on March 22 (set in 1938, probably will stand on Thursday), 82 on March 23 (set in 2007, good chance to be tied or broken Friday); for Blacksburg, they are 80 both days, set in 1968 for March 22 and 1966 for March 23 (upper 70s to near 80 are projected each day). Scattered showers and thunderstorms are still possible each day (though likely to be less numerous than Tuesday), so it’s still possible a random storm or outflow or clouds from one nearby could stymie the warming at either site or elsewhere in Southwest Virginia.
More showers and storms are likely over the weekend as a slow-moving cold front pushes into the warmth. The cold front will bring only slightly cooler weather for a day or two after its passing — 60s highs, 40s lows, perhaps — with the warm overall pattern continuing afterward over the central and eastern U.S. There are a few signals that the pattern may start eroding somewhat, allowing a few more cold fronts into our region the next week or two, but any erosion will be slow.
