UPDATE 9 AM, 8/4: Keeping an eye on Ernesto as stagnant, sticky summer weather continues for SW Virginia
UPDATE 9AM, 8/4: An upper-level disturbance over the Appalachians today will enhance shower and thunderstorm chances on this Saturday, with slow-moving, heavy-rain-dumping storms possible in some locations. Not an all-day rain, but more folks will get wet than Friday, especially in the Roanoke and New River valleys, which stayed mostly dry except for a small area in and around Blacksburg. Light southerly winds will continue to bring moisture into the region, and storms will increase with daytime heating. There are already showers occurring along the Interstate 77 corridor. You can follow the latest on Radar / Future Cast. Also note changes in previous update regarding depression in eastern Atlantic become Tropical Storm Florence. END UPDATE
UPDATE 12:05 AM, 8/4: We’ll keep on keeping on both with watching Ernesto churn west-northwest and with more sticky weather this weekend locally, with scattered thunderstorms, enhanced by upper-level impulses and an approaching cold front by Sunday. There are actually three tropical systems to watch — Ernesto in the Caribbean, a new tropical depression (upgraded to Tropical Storm Florence on Saturday morning) way out in the Atlantic not far west of Africa and an area of disturbed weather just east of Florida. Ernesto may well be in the Gulf of Mexico as a hurricane mid to late next week. The disturbance off Florida probably won’t organize much, and the
depression Florence is many days away, if it survives its trip across the ocean. END UPDATE
Just few quick notes in a stagnant dog-days weather pattern:
* Wednesday’s hailstorm did quite a bit of damage to a some car dealerships in the western part of Roanoke and in Salem (article linked here). 200 cars with $4,000 to $5,000 at one lot — that’s about a million bucks.
* Tropical Storm Ernesto (left) developed Thursday and will track into the Caribbean today. By the middle part of next week, Ernesto is projected to be a hurricane posisbly threatening to move into the Gulf of Mexico. Certainly worth watching.
* We are between heat dome high pressure in the south-central U.S. (110+ readings in Oklahoma and Texas again Thursday) and a large summer Bermuda high over the Atlantic. So we’re not really in the core of either the dry, desert-like heat from the west or the humid, sticky heat from the south and east. So our weather will continue to be very warm to hot, but not extremely hot — 80s and low 90s highs — and pretty humid (60s dew points, mostly) with scattered afternoon showers and storms. Being between these high pressure cores may allow some weak disturbances and cold fronts to enhance storms from time to time.
