A slow-moving cold front could be the focus for some heavy rain Thursday and Friday across parts of the desert Southwest and the Southern Plains.
The Weather Prediction Center has issued a slight risk of excessive rainfall Thursday for northern New Mexico and most of west-central Texas. A flash flood watch has also been issued for northern New Mexico.
Forecasters said widespread showers and thunderstorms are expected to develop. Some could back-build leading to extended periods of very heavy rain and flash flooding.
The threat shifts east for Friday. The WPC has issued a slight risk for excessive rainfall for southern Oklahoma and all of central Texas. No watches have been issued for the region yet.
More back-building thunderstorms are forecast Friday, which could again lead to flash flooding.
Between 2 and 3 inches of rain is forecast across a large swath of Texas, Oklahoma and Arkansas through the weekend. Some places could see as much as 4 inches of rain.
The rain appears it will miss areas where it is badly needed. Much of Kansas and the Oklahoma and Texas panhandles are experiencing the first stages of drought.
