145 FXUS64 KFWD 201750 AFDFWD Area Forecast Discussion National Weather Service Fort Worth TX 1250 PM CDT Mon Jul 20 2026 ...New SHORT TERM, LONG TERM, AVIATION... .KEY MESSAGES... - Prolonged dry and hot conditions are expected this week with temperatures in the mid 90s to low 100s. - A Heat Advisory remains in effect for much of North and Central Texas this afternoon through 8PM Tuesday for peak heat index values up to 108 degrees. && .SHORT TERM... (This afternoon through Tuesday) Issued at 1236 PM CDT Mon Jul 20 2026 High pressure settles in overhead today, bringing sunshine and hot temperatures. Highs today will be in the upper 90s to low 100s, with warm overnight lows in the mid-70s, with low-80s for the Metroplex. A Heat Advisory is in effect for much of North and Central Texas through 8PM Tuesday evening. Max heat index values up to 108 are expected, with little overnight relief. && .LONG TERM... (Tuesday night through next Sunday) Issued at 1236 PM CDT Mon Jul 20 2026 High pressure parks itself over the Southern Plains for the remainder of the forecast period, keeping skies sunny and temperatures hot. Afternoon highs in the low to mid-100s will be common through the end of the work week, with overnight lows struggling to drop below 80. In some spots, these overnight lows may approach near-record warm values. Heat Advisories are likely to be needed through the rest of the week. There is a low chance of needing an Extreme Heat Warning on Wednesday, as increasing moisture combined with the hottest forecasted temperatures of the week have resulted in forecast heat index values climbing above 110. However, this is the first forecast cycle to show such high and widespread heat index values, contributing to the lower confidence. All the same, make sure to take the necessary steps to keep you and your loved ones safe from heat- related illness this week. The developing Tropical Depression in the eastern Gulf could throw a welcome wrench into this period of prolonged heat. Current guidance has come into alignment that this disturbance will approach the southern or southwestern Texas Coast in the Thursday - Saturday timeframe, which would bring increased cloud cover and rain chances, along with cooler temperatures. That said, uncertainty remains high with the details of this system`s progression, especially the track. It is these details that will determine who sees rain and cooler temperatures, and who doesn`t. So stay tuned. && .AVIATION...
