A short-term weakening of the upper level heat ridge will result in a few days of slightly ‘less hot’ temperatures before the weekend. Once the work week ends the high pressure overhead reintensifies and temperatures increase a few degrees again. Honestly the temperature difference from today compared to a few days ago or a few days from now won’t be too noticeable. Today will be hot, tomorrow will be hot, the weekend will be hot, and next week will be hot. Anything different in July either means a hurricane is making landfall, a major flooding event is underway, or a once in a few year event is allowing temperatures to be comparatively cool. None of those look remotely likely over the next week.
Temperatures this afternoon will climb into the 90s across all of Texas. If you by chance don’t stay in the 90s you’ll be climbing into the triple digits. Those most likely to see temperatures over 100 degrees today are in the Permian Basin, Big Country/Concho Valley, and Deep South Texas. By the weekend I believe we’ll see triple digit temperatures return to more of Texas. Heat index values of 100 to 105 degrees are expected today along and east of Interstate 35 where humidity values will be higher. So even with temperatures ‘only’ in the upper 90s in North and East Texas its going to feel plenty hot.
Scattered thunderstorms will be possible in the Permian Basin today. Isolated thunderstorms will also be possible in West Texas, the Texas Panhandle, Northeast Texas, and in Southeast Texas along the coast. Stronger storms may briefly produce small hail and gusty winds. Severe weather is not expected to become an issue today. As always any thunderstorm is capable of producing dangerous lightning which is a direct threat to those outdoors.
For tonight temperatures will fall back into the 70s statewide. The Panhandle may see a few upper 60s and the Davis/Alpine mountains will cool into the mid 60s. Rural parts of Texas will fall into the mid 70s. Larger cities will fall into the upper 70s. Parts of the D/FW Metroplex could struggle to drop below 80 degrees tonight which is concerning for those without air conditioning or the elderly.
