8/17/2013 Daily Update: Dry Weekend, Flooding Potential in Gulf and Southeast

Good morning everyone!

Similar story with wall-to-wall sunshine and seasonable temperatures. The weekend is going to be great!

TODAY: Sunny with highs in the upper 70s to lower 80s. Light winds from the N-NE.

TONIGHT: Few clouds move in with temps dropping into the lower to mid 50s. Calm winds.

TOMORROW: Sunny turning more cloudy in the afternoon with a system moving south of the area. Highs in the upper 70s to lower 80s. Winds from the SW at 5-10 mph.

A peek at next week - We heat up starting Tuesday with increasing humidity and temperatures rising into the 90s. Still no considerable precipitation in the offing thanks to high pressure not budging.

ATLANTIC TROPICS

• Invest 92L continues to churn in the Gulf of Mexico and there are signs of the system trying to wrap itself around with circulation NW of the Yucatan Peninsula. Even if it doesn't develop, tropical moisture associated with the upper level low brings the potential for flooding in the Gulf Coast and Southeastern states this weekend. NHC gives chances of development at 40% in the next 48 hours.
• After a brief downgrade to a tropical depression yesterday, Tropical Storm Erin regains her form. Anyhow, Erin will only pose a threat for mariners as she is expected to dissipate due to dry air from the Saharan Air Layer (SAL).
• A big tropical wave coming off of Africa behind Erin needs to be watched closely. It should track south of Erin and be in a more favorable environment by taking a track south of the SAL.

• Dry and pleasant in the Northeast and Mid-Atlantic
• Flooding rain potential from upper level low in the Gulf for the Gulf Coast and Southeast
