Texas Weather Warning as Storms Could Cause Heavy Rainfall, Flash Flooding

Flash flooding is possible in parts of Texas today, with severe weather forecast for areas of the Lower Mississippi Valley and Southern Plains.

Although the showers and storms are ending west to east early Tuesday morning, according to the San Antonio National Weather Service office, some isolated showers and storms could redevelop later this afternoon and evening.

As the conditions across south-central Texas improve and rain ends across the San Antonio metro area, brief gusty winds of 40-50 miles per hour are possible.

However, there is currently a slight risk of severe thunderstorms in areas of southwestern Texas, as forecasters say there is a threat of very large hail, locally damaging winds, and possibly a tornado. The threat may also extend into south-central Texas.

The ongoing thunderstorms northwest of Del Rio have the potential to grow into a cluster that could spread southeastward, though the extent of the growth is uncertain.

The National Weather Service says that the slight and marginal risk areas have been expanded slightly eastward to account for any potential threat later tonight. The forecast in south-central Texas remains wet through Saturday, with the risk of heavy rainfall and flooding possible until Sunday.

The National Weather Service has also said that a weak area of low pressure, that is currently located over northeastern Texas, will likely move east-northeast over the next few days, entering the Ohio Valley by Thursday morning.

Meanwhile, showers and thunderstorms are likely to develop as severe weather and flash flooding are a concern across the Lower Mississippi Valley and areas of the Southern Plains today.

The Weather Prediction Center has issued a slight risk of excessive rainfall warning from southern Missouri to Louisiana, where there is a risk of rain resulting in flash flooding.

On Wednesday, showers and thunderstorms are expected to move into the Ohio and Tennessee valleys, though they will also linger over central and southern Texas.

These thunderstorms will be capable of producing damaging wind gusts and isolated tornadoes in northern Mississippi and southwest Ohio. The National Weather Service has also warned of isolated flash floods in these areas, as local rainfall could potentially reach more than two inches.

On Wednesday, there will be a marginal risk of severe thunderstorms over areas of the Southern Plains, as well as the Tennessee and Ohio Valley areas.

There is a possibility of isolated severe thunderstorms, capable of large hail and downburst winds, in eastern New Mexico and west through south Texas tomorrow, with isolated strong to severe gusts possible from the Tennessee Valley into southern areas of the Ohio Valley.
