Tropical moisture associated with the former T.D. 7 may be drawn into the southwest Gulf of Mexico this weekend, which could lead to the development of a new system.
Our meteorologists continue to monitor the remnants of former Tropical Depression Seven which was ripped apart over the central Atlantic last weekend.
AccuWeather.com Tropical Expert Dan Kottlowski states that "This wave is still moving rapidly westward at about 20 mph over the western Caribbean. Given this speed a good part of the wave will move inland over eastern Nicaragua and eastern Honduras by Thursday morning."
However, this isn't the end of the problems that this feature could cause for the U.S. or Mexico.
The Gulf of Mexico and much of the Caribbean are being dominated by an elongated area of high pressure which has two centers, one over the northern Bahamas and another over the Southwest.
A southeasterly flow of air around this high could send some of that remnant tropical moisture into the southwestern Gulf by Friday or Saturday.
This moisture could then be drawn up into northeastern Mexico and southern Texas sometime over the weekend or early next week, bringing a threat for tropical downpours to Brownsville, McAllen, Harlingen and perhaps Corpus Christi.
Most of this area is suffering from a severe to extreme drought according to the U.S. Drought Monitor.
Rainfall has been highly variable across southern Texas this month with Brownsville receiving almost 3.5 inches of rain while McAllen has picked up just a trace. Harlingen has only received 0.17 of an inch thus far in August.
Therefore, any rainfall will be welcomed with open arms especially after McAllen has been above 100 degrees 12 of the 13 days this month!
What About Tropical Development??
AccuWeather.com meteorologists are also concerned about the potential for tropical development in association with the remnant moisture of T.D. 7 once it gets into the southwestern Gulf.
AccuWeather.com Meteorologist Andrew Mussoline stated that "The chance for tropical development appears low; however, we can certainly see some beneficial rains being pulled northward into southern Texas."
Conditions over the weekend will be somewhat favorable to sustain a tropical entity over the southwest Gulf with relatively light winds aloft and high pressure in place overhead.
Along with that, sea surface temperatures over the Gulf are very warm, averaging between 28-30 degrees Celsius which is more than warm enough to sustain tropical features.
The bottom line is that there are a lot of factors to watch over the next few days in terms of how this moisture gets drawn northward and what track it takes.

While prospects for a white Christmas are grim along the I-95 corridor, many communities from the Great Lakes to the Rockies should enjoy the desired snowy scene for the holiday.
The first substantial snowstorm of the season, which totaled nearly 5 inches of snow in some areas, was responsible for widespread slide-offs and accidents in Kansas City during the commuting hours.
After natural disasters, it’s not uncommon to see pop-up charities appear, particularly around the holiday season.
A storm bearing strong winds, heavy snow, torrential rain, thunderstorms and fog will converge on the Northeast and Midwest on Christmas Eve and will likely create ground and flight delays.
As millions of people prepare to travel for the winter holidays, wet weather in the Northeast may make some travels problematic.
As the train of storms from the Pacific Ocean continues, rounds of rain and mountain snow will affect areas from the Northwest to the Intermountain West and Rockies through Christmas Day.
