TROPICS: Tropical Depression 17 Forms in Gulf of Mexico


The lower clouds arrive tonight.

Windy, cold weather should dominate the rest of next week with off & on shortwaves & cold fronts bringing mostly cloudy skies & spotty rain & snow showers.

The thunderstorm activity is becoming better organised, the agency reports, and if this trend continues a tropical or subtropical cyclone could form later on Friday. Heavier bands of rain dumped up to six inches on areas west of New Orleans. Instability will be limited and lapse rates rather weak, so for now we are not expecting organized severe storms.

A general 3-6 inches of rain is forecast to fall from the central Gulf coast to southern IL and southern IN with an AccuWeather Local StormMax™ of 8 inches IN parts of Mississippi, Louisiana, eastern Arkansas, western Alabama and Tennessee.

There could be a tropical depression in the Gulf today. Most of Saturday is looking flawless, cooler, and breezy with a mix of sun & clouds. Highs for Sunday will be in the mid to upper 80s.

NEXT WEEK: A decent part of the week will be dry, but models are showing mixed signals concerning precipitation along a cold front at midweek.

Tropical Storm Pablo became a hurricane on Sunday morning as it moved quickly over the northeastern Atlantic. Olga is expected to merge with the cold front and become a post-tropical low with gale-force winds during the next few hours before the center reaches the Gulf coast.

Low overcast Sunday morning will begin to clear & the winds will diminish. Temperatures stay chilly as well so we get a double whammy of a chill in the air combined with the rain.

Rain sticks around for much of the afternoon with a light to moderate rainfall for southwest Louisiana. It appears that the spotty rain & snow Thursday may taper off by 6 p.m.
