Here’s a surprising little statistic that seems to swim upstream against the fact that the March-April-May period was the warmest spring on record for Roanoke — it still has not hit 90 degrees on any single day (high was 89 of 4 different days). And it won’t get close to that today, because of what is known as an “in-situ” wedge of cooler air. The wedge is created by persistent showery weather creating a pool of cooler air east of the spine of the Applaachians, rather then more familiar wedge pushed in by high pressure from the northeast (what we would call “cold-air damming” in winter). Most areas won’t get out of the 60s today.
So, whenever it finally makes 90 (possibly the weekend), it will be Roanoke’s latest date for its 1st 90-degree high since at least 2004 (June 11) and if it delays much later, since 2003 (June 20).
I’m back home and recovering from an unusual and intense Virginia Tech storm chase trip. More on that later.
