Additional Heat Advisories have been place in effect today across southeast and south central Texas where some areas could see heat indices between 108 and 110 this afternoon. Most of these will remain in effect through Monday. Widespread highs in the low 100s is expected again today. The coolest spots in the state will be across the central to northern panhandle as a weak frontal boundary has pushed into the area. Western Texas, especially in the mountain regions, will also see cooler highs only in the 90s. Overnight lows will range in the 70s across most of the rural areas, to upper 70s low 80s for the metro areas. We could see a few 60s in the aforementioned panhandle/western Texas regions overnight, but other than that, quite warm and pretty typical for August.
We are expecting a bit of a pattern change by next weekend as the ridge of high pressure slowly drifts westward during the work week and the weak cold front drops down through north and into central Texas. This will begin to bring some rain chances back into the forecast for additional parts of the state. It won’t be much, so don’t get your hopes very high, but by the middle to end of the week, we could be looking at the return of chances for showers across north and central Texas mainly along and near the stalled frontal boundary. By the weekend, we could be seeing increased chances for scattered rain across central and west central Texas. Way too early to be certain of that, but it’s a hopeful sign in the long-range forecast models. Overall, the preferred area for rain chances will remain across the panhandle and western Texas as it has the past week due to seasonal monsoon moisture. The biggest impact of this week’s weather system will be some cooler temps for north and parts of central Texas.
