A change in the weather on the way...

While we're still dealing with the heat and humidity, change is on the way. A cold front will slide through Virginia on Tuesday and a pleasant air mass with lower humidity will build over the Mid-Atlantic Wednesday and Thursday. Then another front will come through late Friday night and early Saturday. This will bring a taste of fall for the weekend, with afternoon highs in the upper 70s and overnight lows in the 50s Sunday and Monday.

Maybe another surge of cool air later next week...

The trend is definitely toward cooler weather. Our longer range data suggests another cool air mass sliding into the East next Thursday and Friday, with a digging upper trough. However, there are signs that the flow could quickly flatten again by the following weekend (September 22-23).

More action in the tropics?

While we are saying goodbye to Gabrielle, a rather large area of showers and thunderstorms located midway between the Windward Islands and the Cape Verde Islands is being watched closely for development. It is getting better organized and could become a tropical depression within the next couple of days as it moves to the west-northwest. One other area over the western Gulf of Mexico has some potential for development as it moves to the west.
