492 FXUS64 KFWD 111043 AFDFWD Area Forecast Discussion National Weather Service Fort Worth TX 543 AM CDT Tue Aug 11 2026 ...New AVIATION... .KEY MESSAGES... - Increasing southerly winds, seasonably hot temperatures, and low humidity will support an increasing threat for wildfires across North and Central TX through the week. && .SHORT TERM... (Tonight through Wednesday) Issued at 1212 AM CDT Tue Aug 11 2026 Mid level ridging will continue to promote seasonably hot afternoons through the middle of the week with little chance for rainfall. Some passing high clouds can be expected overnight tonight into Tuesday morning. Otherwise, low level moisture has pooled along the TX coast into the Hill Country where PW values have climbed to near 2 inches. This additional moisture may lead to some low clouds that will try to spread into the Brazos Valley through the morning. Otherwise, skies will be mostly sunny on Tuesday and Wednesday with highs near 100 degrees both days. Low level moisture will be a touch higher today despite modest boundary layer mixing. Some of the moisture currently in Central and Southeast TX will spread north through the afternoon and dewpoints will likely tick upward a few degrees. This should result in some heat index values between 104-107 degrees across our northern counties where temperatures will be a few degrees warmer. The current heat advisory configuration addresses this potential and no additional changes are required at this time. A deepening surface low over eastern Colorado will help tighten the pressure gradient through the middle of the week and we`ll see southwesterly winds increase in response. This should promote deeper mixing on Wednesday afternoon and high res guidance shows dewpoints falling back into the upper 50s and lower 60s which should preclude the need for an additional Heat Advisory on Wednesday. The increased winds will also result in cooler WBGT values with readings in the 86-88 degree range Wednesday afternoon. We`ll also be monitoring an increasing threat for wildfire activity through the week. Shortwave IR imagery shows the 3000 acre Bufford Creek fire in northern Stephens County at this hour. Increasing winds and low humidity will continue to support wildfire activity across the region through the week. Dunn && .LONG TERM... (Wednesday night through next Monday) Issued at 1212 AM CDT Tue Aug 11 2026 Little change in the pattern is expected into the upcoming weekend with hot and dry conditions expected to continue as mid level ridging expands eastward. A weak mid level disturbance will round the western periphery of this ridge axis on Friday and Saturday spreading into Deep South Texas and eventually into the Hill Country. While it`s unlikely that we`ll see any significant precipitation associated with this disturbance, we may see a slight increase in sea breeze convection across southeast TX which may eventually spread into some of our southeast counties Friday and Saturday afternoons. Otherwise, mid level heights will continue to increase into the weekend with temperatures expected to respond upward. We`ll likely see highs in the 101-105 degree range by Sunday and Monday. Concerning the fire potential, Thursday looks like the day when we`ll see the strongest winds with minimum RH values as low as 20% across parts of our western counties. Current median peak wind gusts for Thursday are right around 30 kt which would certainly raise the concern for any ongoing and potentially new fire activity. Dunn && .AVIATION... (12Z TAFS) Issued at 536 AM CDT Tue Aug 11 2026 A fairly decent patch of MVFR cigs has expanded out of southeast TX into the region this morning and intermittent MVFR cigs are expected at Waco for another hour or so. These clouds have pushed into the far southeastern parts of the D10 airspace, but no airport impacts are expected at this time. VFR should prevail through the period with southerly flow around 15 kt.
