General Discussion: Wednesday marked the return of an unsettled, stormy weather pattern that will continue the remainder of this week through most or all of next week. Each day will include rain impacting parts of the ERCOT system. Sunday through Tuesday shows potential for widespread showers and thunderstorms. The increased cloud cover and rain opportunities will limit the afternoon heating across Texas for the remainder of this month. Most locations are unlikely to match the daytime highs from the past three days moving forward through the end of May.

Today: More clouds than sunshine today. Scattered showers and thunderstorms could impact any location with exception to most of Far West Texas. Lingering showers and thunderstorms this morning into early-afternoon across roughly the eastern half of the state, especially South Central and South Texas. Some stronger storms will fire during the mid-to-late afternoon hours over portions of Central, Northeast, and West Texas, in particular. Most locations will be cooler than yesterday; however, parts of North Texas into the Panhandle will be several degrees warmer. 80s for highs will be common. Some hotter 90s in Far West Texas with greater potential for sunshine and much less chance of rain. Upper-80s to lower-90s for the Coast and South Central zones this afternoon.

Tomorrow: A bit less rain coverage on Friday, which will allow many locations to experience afternoon highs a couple of degrees hotter than today. Still, daytime heating will promote scattered showers and thunderstorms to again develop, especially impacting the middle third of the state on a north-south axis. Rain chances will increase during the holiday weekend.
