Unimpressive Showers

A front moves across the Southern Appalachians around midday. Rain with the front has been unimpressive; however, we must account for a lingering isolated shower this afternoon. Thursday and Friday, high pressure centered in the Great Lakes will produce pleasant weather. The weekend has more clouds with spotty light rain possible because of a moist, easterly fetch off the Atlantic.

Forecast Discussion

A front is barreling across the Southern Appalachians and into the foothills this afternoon. It's a quick mover and poorly timed to produce much rain; however, a straggling afternoon shower is possible. Temperatures will be several degrees lower than the last few days.

Thursday and Friday look terrific. The front will be well to our south and east, and high pressure centered in the Great Lakes takes charge of our weather.

This weekend, the high to our north produces a moist, easterly flow off the Atlantic. Add clouds, subtract 5-6 degrees, and spotty light rain or drizzle will be possible both days. Monday and Tuesday look somewhat drier but a stray shower cannot be ruled out.

The remnants of Tropical Storm Harvey starts making news. It's in the Bay of Campeche, and will restrengthen potentially into a hurricane before reaching the Texas Coast this weekend. Harvey will stall near the Texas Coast then slowly move northeast into Louisiana. Eventually it will move up the Mississippi and Tennessee River Valleys; however, timing is impossible at this point. Harvey's moisture will reach us, but probably not until the second half of next week.

A second tropical disturbance currently in the Bahamas may strengthen as it lurks east of the Atlantic Coast early next week. It will have no direct effect on our weather.
