Multi-Day Severe Weather, Flood Threat for South


It’s that time of year again.

Severe weather and potentially significant flash and river flooding could hamper much of the South this week as a Spring-like weather pattern takes hold of the region.

A slow-moving area of low pressure, part of an active weekend picture across drought-stricken California and Nevada, will nudge eastward on Sunday and into the start of the work week. Coupled with a dry line (separating humid and dry air masses), the ingredients are in place for a multi-day severe weather threat that could feature tornadoes, hail and strong, damaging winds from Texas to Nebraska.

Additionally, flooding will be a big concern, especially by the middle of the week as several days of heavy rainfall take their toll on the Ark-La-Tex region, where over six inches of rain could fall in the next seven days.

The storms are expected to start on Sunday across the Texas and Oklahoma panhandles and into far southwestern Kansas, where damaging hail and strong winds could develop late Sunday evening. But by Monday, the threat zone expands considerably (see map). Areas as far north as Minnesota could see strong storms, but it’s Texas and Oklahoma that could see the strongest storms, with tornadoes an increasing possibility by the start of the work week. Tuesday, however, the threat zone moves slowly eastward into the I-35 corridor of the Lone Star State and into far western Louisiana, with tornadoes, hail and strong winds all possible as well. By Wednesday, it’s Louisiana and southern Mississippi in the threat zone for severe weather.
