Lubbock, Post, Plainview, Tulia, Childress, Haskell, Wichita Falls, Graham, and Mineral Wells are a few towns included.

Our first thunderstorms of the afternoon have developed across the western Texas Panhandle from near Romero southeast to Hereford to Plainview to Crosbyton. Most storms are moving southeast at 30 to 35 MPH. Intensification is anticipated with these storms and we should have a few of them becoming severe by 5 PM. Semi-discrete supercells will continue through the early evening. Those storms will make their way into West-central Texas and into Northwest Texas. Additional storms may develop around 8-9PM across Northwest Texas. A small complex of thunderstorms will organize and move southeast into western North Texas late this evening. The strongest storms in that complex may be capable of producing damaging straight-line winds, hail, and heavy rainfall. Storms will be weakening as they approach Interstate 35 in North Texas around or after midnight.
