Fall Preview

We are going to get a taste of Fall beginning today through the rest of the week. A cold front moves through the area later today bringing an end to the showers. Cool dry air will settle into the southern Appalachians and hang out through the weekend. Thursday and Friday look great for outdoor activities. The weekend does not look as nice with the possibility of low clouds and cool temperatures.

Forecast Discussion

A cold front moves through today. Showers this morning will gradually end by late afternoon as cooler and drier works its way in. The weather for Thursday and Friday will be almost perfect with mostly sunny skies and pleasant temperatures and humidity.

High pressure at the surface will get locked in over New England by the weekend and wedge down the Appalachians. The low level flow around the High will be from the northeast and east grabbing some moisture from the Atlantic. This moist flow of air moving up into the Appalachians typically produces low clouds and occasional drizzle and light rain for the southern Appalachians. Unfortunately, the weekend does not look as nice as Thursday and Friday but it will not be a washout by any means. Temperatures will be cool with the clouds and fall like air mass in place.

The Atlantic tropical season is becoming active. The remnants of Tropical Storm Harvey are moving into a favorable environment for development in the Bay of Campeche. The system should regain its name of Harvey as it develops into a tropical storm once again by Friday. Harvey will likely affect southeast TX beginning Friday and into the weekend.

There is a tropical disturbance over south Florida which has a small chance of developing into a tropical storm as it moves over the Atlantic north of the Bahamas in the next few days. This system will likely remain offshore of the southeast and mid Atlantic coasts.
