763 FXUS64 KFWD 131740 AFDFWD Area Forecast Discussion National Weather Service Fort Worth TX 1240 PM CDT Sun Sep 13 2026 ...New SHORT TERM, LONG TERM, AVIATION... .KEY MESSAGES... - A Heat Advisory is in effect for portions of North and Central Texas through 8 PM Monday. - Hot and dry conditions will continue through the upcoming work week. && .SHORT TERM... (This afternoon through Monday) Issued at 1146 AM CDT Sun Sep 13 2026 As ridging builds over much of the southern and southeastern CONUS, synoptic scale subsidence and surface high pressure will allow dry conditions and above normal temperatures to persist today into tomorrow. Despite strong diurnal mixing throughout the afternoon, surface dew points in the 60s and low 70s along with afternoon highs in the upper-90s and lower-100s will result in peak heat indices ranging from 100-107 degrees. As such, a Heat Advisory is in effect across much of North and Central Texas today. Tomorrow, the Heat Advisory is confined to the I-35 corridor and eastward. This area will see richer boundary layer moisture and higher heat indices (105-107 degrees) compared to west of the I-35 corridor (100-104 degrees) where strong mixing and gusty southwesterly winds will help afternoon dew points drop into the upper-50s and lower-60s. The abundant boundary layer moisture and a weakness in heights over the Gulf Coast will promote very isolated rain showers across portions of Central and East Texas (~10% chance) Sunday and Monday afternoons. Any shower that is able to develop will likely be brief in nature due to the entrainment of very dry air above the boundary layer. && .LONG TERM... (Monday night through next Saturday) Issued at 1146 AM CDT Sun Sep 13 2026 Stubborn ridging aloft and the lack of any surface boundaries across the region will result in the monotonous hot and dry weather pattern across the region to continue through the work week. Medium range guidance that resolved a potential weekend cold front continues to shift it later into the following week with the most recent model runs diminishing the potential for any cooler airmasses to work south into the area by the end of this forecast period. However, troughing over the western CONUS looks to deepen this upcoming weekend, shunting the strong ridge currently overhead to the east and bring in southwesterly flow aloft. This flow regime change may favor the return of low rain chances around or just after the end of this forecast period. && .AVIATION... (18Z TAFS) Issued at 1146 AM CDT Sun Sep 13 2026 MVFR cigs (BKN010-020) are expected to develop across portions of Central Texas 10Z-15Z. There is a low chance (10-20%) these clouds may develop north enough to bring brief reduced cigs to KACT, however this scenario is too unlikely to include in TAFs at this time. As such, expect VFR conditions and southerly flow at 9-15 knots to prevail at all TAF sites through the duration of this forecast period. && .SPOTTER INFORMATION STATEMENT... Spotter activation is not expected at this time. && .PRELIMINARY POINT TEMPS/POPS... Dallas-Ft.
