865 FXUS64 KFWD 031047 AFDFWD Area Forecast Discussion National Weather Service Fort Worth TX 547 AM CDT Wed Jul 3 2024 ...New Aviation, Short Term... .SHORT TERM... /NEW/ Update: The previous forecast remains largely unchanged. Minor adjustments were made to the wind speed forecast as well as expected daytime temperatures. The heat will continue through the 4th of July, posing a hazard to those celebrating outdoors. The Heat Advisory will continue through sunset tomorrow. Ensure you take the necessary precautions to avoid heat-related illnesses. Hernandez Previous Discussion: /Through Thursday/ The mid-level ridge across North and Central Texas continues to deflect any prospects for rain away from the region. Instead, we`ll continue to experience above normal temperatures with even warmer heat index values. Today, temperatures across North Texas will mostly range between 100-104 degrees with heat index values between 106 to 108. In Central Texas, highs will remain in the mid to upper 90s, however, given better moisture, heat index values will also range between 106 to 109. Not much overnight recovery is expected tonight with temperatures in the upper 70s to lower 80s. 4th of July will be another hot one with temperatures reaching the triple digit mark across much of the region. With heat index values above 105 degrees, plan now on ways to mitigate the risk of heat related illnesses if you`ll be celebrating outdoors. Bring plenty of water, seek shade, and wear lightweight and light- colored clothing! Hernandez && .LONG TERM... /Issued 301 AM CDT Wed Jul 3 2024/ /Thursday Night Onward/ The eastward shift and breakdown of the mid-level ridge overhead will open the door for returning convection and relief from the ongoing oppressive heat through the extended forecast period. As 4th of July outdoor activities wind down Thursday evening, our focus will be on the cold front sliding through southern Oklahoma and West Texas. The front is projected to move into North Texas Friday morning, with a gradual slowing of its southward progress later in the day in response to the departing upper trough. While large-scale forcing for ascent will largely be displaced to the north/northeast, frontogenetical lift from the surface boundary should be sufficient for isolated to scattered showers and thunderstorms in the vicinity of the front. The risk for severe weather generally appears low however, given the unfavorable timing of this initial convection...during the overnight/pre-dawn hours when instability is at a minimum...and weak vertical wind shear. There is likely to be a moderate spread in afternoon temperatures on Friday between areas under the influence of increased cloud cover/rain-cooled air and the sunny prefrontal warm sector. The result will be high temperatures in the upper 80s to lower 90s along and behind the front and the mid/upper 90s ahead of the front. Depending on where the boundary settles, the combination of strong diurnal heating (ahead of the front) and ample available moisture is likely to allow for some airmass destabilization and the potential for a few strong storms during peak heating on Friday. The main area to watch looks to be near and south of I-20 and east of I-35 where moderately strong instability may be realized. Though the front is expected to stall or maybe even retreat northward on Saturday, rain chances and increased cloud cover should keep temperatures near or below climatological normals across the entire region on Saturday. Morning lows will be in the 70s and afternoon highs will be in the lower 90s. North and Central Texas will remain situated between ridges late weekend and into next week with broad troughing to the north. Shortwaves passing through the resultant weak northwest flow aloft will maintain an unsettled pattern complete with lingering rain chances and relatively mild (near-average) temperatures before upper ridging builds east of the Rockies mid to late week. Hurricane Beryl, currently a CAT 4 Hurricane in the Central Caribbean, is expected to emerge over the Bay of Campeche Friday evening as a tropical storm. The weakness or col over the south- central U.S. may encourage Beryl to take a more north/northwestward turn into the Western Gulf of Mexico this weekend. Uncertainty remains in how the land interaction along the Yucatan Peninsula will weaken the system, the shear profile over the Western Gulf, and how the position/strength of the col/ridge pattern over the central U.S. will affect the track. This uncertainty could affect the extended forecast for areas spanning from Tampico, Mexico to Lake Charles, Louisiana and points inland. For North and Central Texas, the evolution of Beryl is worth watching for potential direct or indirect impacts. 12 && .AVIATION... /NEW/ /12Z TAFs/ No significant weather is expected within North or Central Texas. VFR and southerly winds will persist through the duration of this TAF cycle. Hernandez && .PRELIMINARY POINT TEMPS/POPS... Dallas-Ft.
