664 FXUS64 KFWD 060925 AFDFWD Area Forecast Discussion National Weather Service Fort Worth TX 425 AM CDT Sat Jul 6 2024 ...New Long Term... .SHORT TERM... /Issued 155 AM CDT Sat Jul 6 2024/ /Today and Tonight/ This morning will start on the cool side of average for most in the wake of yesterday`s cold front. Parts of western North Texas will start the day 7-10 degrees below average with lows in the mid 60s while the rest of the area starts in the low to mid 70s. Yesterday`s cold front was able to move as far south as the Hill Country, but it will start to mix out this afternoon, then fully wash out tonight/early Sunday morning. Unfortunately, this means we`ll return to near seasonal norms this afternoon with highs topping out in the low 90s. Meager mid-level ascent around 700 mb should develop a few showers across the area early this morning. Limited instability should keep the threat of lightning low. Scattered showers and storms are expected to develop this afternoon across Central Texas, mainly in the vicinity of the surface front. All storms should end with the loss of heating this evening. South flow will return tonight and start to draw warm, moist air north in advance of our next weather-maker expected to move into the area Sunday night into Monday. Bonnette && .LONG TERM... /NEW/ Key Messages: - Quick warm-up should push heat index values back into the triple digits on Sunday. - An MCS capable of producing strong wind gusts will move into North Texas Sunday night into Monday morning. - There is an increasing threat for heavy rainfall and flooding over portions of North and Central Texas associated with the landfall of Tropical Cyclone Beryl on Monday. Details: Southerly surface winds will begin to increase on Sunday in response to pressure falls in the lee of the Rockies. This will allow for a quick warm-up with afternoon temperatures climbing into the mid and upper 90s. Diurnal heating of the moistening boundary layer (bolstered by the tropical moisture associated with Tropical Storm Beryl) will result in triple digit heat index values. Though some locations are likely to flirt with Heat Advisory criteria during peak heating, the occurrence of these conditions is expected to be isolated and brief enough to preclude the need for heat headlines. The convection that will likely be ongoing across southern Kansas and northern Oklahoma at the start of the period may only make it as far as central Oklahoma before weakening and pushing east. This will generally leave North and Central Texas precipitation-free until the afternoon when the outer bands of Beryl begin moving up from the coast. By the early evening, thunderstorms will quickly develop along the southeastward surging cold front in Oklahoma and the Texas Panhandle. Upscale growth is expected as these storms progress east/southeast into North Texas overnight and early Monday. Strong wind gusts and heavy rainfall will be the main concerns with this activity. Early Monday, the focus will be on the northwestern Gulf as Beryl reaches the coast. The latest NHC forecast calls for Tropical Storm Beryl to re-strengthen into a hurricane before making landfall somewhere along the middle Texas coast. As the system moves onshore, the current track arcs Beryl across the eastern half of our domain. Initially, the greatest threat for heavy rainfall will be east of the circulation, impacting Southeast and eastern Central Texas. However, as Beryl progresses further north/northeast (and becomes increasingly extratropical), the axis of heaviest rainfall will likely begin to wrap around the northern flank of the circulation. This will shift the flood threat further north and west across our area. We also cannot rule out the emergence of a localized tornado threat associated with the rain bands moving onshore. Rain/storm chances will persist through the end of the week as ridging over the Intermountain West and the southern Appalachians/Southeast maintains the position of the weakening trough over the central CONUS. The lingering tropical moisture should support daily chances for showers and storms. This extended rainy period should also keep temperature seasonable or slightly below climatological normals with highs in the upper 80s to mid 90s and lows in the upper 60s to mid 70s. 12 && .AVIATION... /Issued 155 AM CDT Sat Jul 6 2024/ /06Z TAFs/ VFR and light north flow will prevail for most of the day. A SCT to BKN cloud deck around 10-15 kft will develop a few showers early this morning with most of this activity remaining south/west of D10. These showers should brush by ACT near/after sunrise this morning. A few hour lull in precip activity is expected until scattered storms develop this afternoon near the cold front south and east of ACT (and D10). The chance of a storm impacting ACT is around 10%, so VCTS was not included in the TAF. Light south flow will return to the D10 terminals this afternoon, and this evening at ACT.
