After thunderstorms brought large hail and damaging winds to portions of the southern Plains Wednesday, the threat for severe storms will continue Thursday.
Severe thunderstorms could impact Dallas, Texas, Tulsa and Oklahoma City, Okla., and St. Louis, Mo., during the afternoon and evening hours.
Showers and thunderstorms leftover from the overnight hours will persist into the morning hours Thursday, but the storms should remain under severe limits.
Additional thunderstorms will develop mostly during the afternoon and evening, which is when the best ingredients for severe weather will be in place. A developing storm system over West Texas will draw up warm, moist air from the south. A slow-moving front sitting off to the west will help to trigger the storms.
The main threats with these storms will be large hail and damaging winds. Just like on Wednesday, baseball-sized hail will accompany some storms from southern Oklahoma down into north-central Texas.
"The weather pattern this week does not favor tornado development," AccuWeather.com Expert Senior Meteorologist Henry Margusity said. While some of the strongest storms Thursday could produce an isolated tornado, these storms will be the exception. This continues the trend of the year so far, where the cooler spring has produced well-below average tornadoes across the country.
As Thursday night progresses, heavy rain will become a bigger threat than severe weather as the thunderstorms shift eastward into eastern Texas, Arkansas and Louisiana.
The threat for severe thunderstorms will diminish a bit Friday, but a few strong thunderstorms may impact Houston and San Antonio, Texas, and Shreveport, La. Heavy downpours and localized flooding will likely be the bigger impact from these storms.
