What the forecast actually says

Area Forecast Discussions are the real forecasts, written 3 to 4 times daily by NWS meteorologists reading the models and interpreting what they mean for your area. They offer far deeper insight than any weather app, but they're written in dense meteorological shorthand. Plaincast uses Anthropic's Claude to summarize them into plain English, side by side with the annotated original.

A Heat Advisory remains in effect through 8PM Tuesday evening across much of North and Central Texas where heat index readings could reach up to 109.
Hot and rain-free weather will persist through the work week with little relief in sight, and additional Heat Advisories or possibly Extreme Heat Warnings may be needed.
(Today and tonight) Issued at 120 AM CDT Tue Jul 28 2026
Ridging aloft will dominate the weather pattern over the next several days keeping hot and dry conditions over North and Central Texas through the short-term forecast period and much of the work week. Expect highs in the mid 90s to lower 100s Tuesday afternoon with heat index values peaking in the 105-109 degree range across much of the region. Several Central Texas counties, including Bell and McLennan, were added to the Heat Advisory that is in effect through 8PM Tuesday evening. Make sure you are taking the necessary precautions to keep you and your loved ones safe from heat-related illnesses. More efficient mixing will keep heat index values in our Big Country counties along and west of Hwy 281 near the ambient air temperature. Still hot! But not meeting Heat Advisory criteria. Expect Tuesday night lows in the mid 70s to low 80s.
(Wednesday through Monday) Issued at 120 AM CDT Tue Jul 28 2026
Hot, dry, and mostly sunny conditions will persist through the end of the work week. Afternoon highs may actually start to creep up two to three degrees Thursday-Friday as upper ridging strengthens and spins back toward the Texas Panhandle. Increasing moisture ahead of a weak frontal boundary may also tick heat index values above 110 degrees across parts of North Texas late in the work week, potentially requiring the eventual issuance of an Extreme Heat Warning.
Latest model guidance continues to highlight a rather strong upper low pushing southeastward across the Upper Mississippi River Valley over the weekend shunting the upper ridge west toward the Four Corners and allowing for a weak frontal boundary to slide into North Texas early in the weekend. This may allow for slightly "cooler" temperatures Saturday and Sunday, however the main difference that will be felt is a subtle drop in humidity keeping heat index values mostly below 105 degrees. There will be some moisture to work with along and ahead of the front, so the weakness in the heights aloft along with subtle forcing along the front may be enough to initiate a few showers and storms over the weekend across parts of North and Central Texas. This activity will likely remain very isolated and most locations will continue to experience dry weather conditions. Wind speeds will remain relatively light through at least the next 7 days, but persistent dry and hot conditions and emerging dry, fine vegetation/fuels may lead to an environment supportive of new fire starts as we head further into the week.
