A bit of needed rain falling over Southwest Virginia
I wrote a little about how May was following the trend of most months the last two years in this morning's Weather Journal update in the Roanoke Times. Well, we are getting a pretty widespread rainfall this morning, as an upper-level disturbance moving across Tennessee throws some Gulf of Mexico moisture up over slightly cooler air near the surface. This is called "overrunning" and is common in some of our cooler months, but a little less frequent from late spring through summer. Don't expect a lot of rain, but a few tenths of an inch to maybe locally a half-inch to three-quarters of an inch will be welcome, especially falling slowly as it is. We trail our normal rainfall for the year by nearly 6 inches, so we still have some ground to make up.
