Southern storms set to make for a thunderous end to 2020

Thunderstorms are much more likely to be strong or severe on Thursday. Flash flooding will remain a concern, along with damaging wind gusts. It is not out of the question for an isolated tornado, especially along the immediate Gulf Coast.

A dynamic storm system that is set to deliver snow and ice to parts of the Plains and Midwest will bring a different type of disruptive weather farther south and east.

As a cold front marches southeastward through Texas on Wednesday, warm and moist air will be drawn northward from the Gulf of Mexico. Thunderstorms are expected to develop in eastern Texas and western Louisiana. Although the main threat will be heavy rain, some of the stronger storms could contain locally damaging winds.

"It is possible that a brief fire hose effect develops over eastern Texas and advances eastward across the Deep South with a period of blinding, torrential rain that can lead to flash flooding," according to AccuWeather Senior Meteorologist Alex Sosnowski.

Anyone along interstates 10, 20 and 45 will need to heed caution on Wednesday and Wednesday night. Houston and San Antonio, Texas; and Shreveport, Louisiana, are just a few of the locations that could be impacted.

Thunderstorms are forecast to kick it up a notch on New Year's Eve, and could pack more of a punch in terms of wind.

"The year will end with a bang across a portion of the Gulf Coast states, specifically from far southeast Texas through Louisiana and into Mississippi and Alabama where severe thunderstorms are forecast to erupt," said AccuWeather Meteorologist Renee Duff. "Mother Nature will be creating fireworks of her own as 2021 begins."
