The cluster of thunderstorms in the northwestern Gulf of Mexico became Tropical Storm Humberto today. This storm will make landfall overnight on the Upper Texas coast and then move inland over Louisiana and Mississippi, bringing significant rainfall amounting to 5 to 10 inches there. The abundant moisture may be some good news here in Virginia, as an approaching cold front will hopefully draw this moisture north into our area on Friday. The front is scheduled to arrive Friday night and I expect some showers and thunderstorms to develop during the afternoon and continue into the night. Potentially this could be some beneficial rain, considering the lack of rain we've had over the last two and a half weeks. By Saturday morning, the front will be exiting our area, with more dry and pleasant weather behind it for the weekend.
Meanwhile, way out in the Atlantic, the other tropical wave we've been watching very closely has become Tropical Depression #8. I expect this to become Tropical Storm Ingrid as it moves west-northwest over the next 24-48 hours. By the way, if you're wondering where the name Ingrid came from, it replaced Iris, which was retired in 2001. In fact, the "I" names were retired in the Atlantic/Caribbean/Gulf four years in a row from 2001-2004. The retired names were Iris (2001), Isidore (2002), Isabel (2003) and Ivan (2004).

The heat gives way...
The cold front that moved through Central Virginia didn't produce a whole lot of rain. In fact, here at CBS 6, we only received .05" from the late afternoon showers. The front will move southward into the Carolinas, and we have some very nice weather to enjoy the next couple of days, with lower humidity and afternoon highs in the low to mid 80s.
Next front arrives Friday night...
The next cold front will approach the region Friday evening. It could spark a few scattered showers and thunderstorms, although I don't expect any significant problems for Friday night high school football games. Behind this front, another "cool" and dry air mass will settle over the area for the weekend. I expect temperatures by Sunday to average in the 70s by day and the 50s by night. A few upper 40s are possible in the coolest rural communities!
The longer range and the tropics...
The longer range data is not showing the additional cool-down I was mentioning yesterday. In fact, temperatures should be at or above average later next week (Sept. 20-23), although that may depend on a potential coastal system showing up in the computer projections.
The cluster of showers and thunderstorms that is a little over 1000 miles east of the Windward Islands is showing some good organization tonight and I wouldn't be surprised if it is declared a tropical depression on Wednesday.

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.
