General Discussion: Temperatures will be close to normal today through the weekend for most locations, but a bit below normal in the Coast and South zones. Rain chances will be limited to far eastern, southern, and western portions today. Some scattered showers are expected during the weekend along and near the Coast. ERCOT system temperatures will trend hotter next Monday into Tuesday. Dallas will have a good opportunity to record 100 on each of those days. Houston will see a hotter, drier period. Above 100 Monday and Tuesday in Central Texas. 100 degrees will also be common across most of West Texas early next week. The heat will continue for most of the state Wednesday and Thursday, but rain chances will increase in the Coast zone limiting the daytime heating in Houston.
Today: Plenty of sunshine and dry for the vast majority of the state today. Dry this morning, but a few showers and thunderstorms will develop this afternoon in Far East Texas as well as the Rio Grande Valley. Scattered thunderstorms will pop over portions of the Panhandle and Far West Texas (north of Midland, near Lubbock) late afternoon into evening. Most locations will see afternoon high temperatures within a degree of yesterday’s with upper 90s most common. Around 100 again in Central Texas. Not as hot in the Valley with mid-90s highs.
This Weekend: Continued hot and dry conditions between Dallas and San Antonio this weekend. Upper 90s in Dallas. Upper 90s to 102 in Central Texas. Scattered showers possible both days in or near Houston limiting temperatures to the low 90s for highs. Upper 90s in West Texas both days. Mid-90s common in the Lower Rio Grande Valley with a few upper 90s possible by Sunday.
