526 FXUS64 KFWD 152341 AFDFWD Area Forecast Discussion National Weather Service Fort Worth TX 641 PM CDT Sat Jun 15 2024 ...New Short Term, Aviation... .SHORT TERM... /NEW/ /Through Sunday/ No appreciable changes from the short-term forecast issued earlier today. Through Sunday, the forecast area will remain in a broad col region between two upper level high pressure centers over Northern Mexico and the Southeast U.S. An absence of deep moisture and instability will preclude any significant cloud cover or convective development, apart from a few early morning stratus in the southern zones, and a blossoming of afternoon fair weather cumulus elsewhere. With limited subsidence in play, our afternoon highs Sunday should remain near seasonal norms - lower 90s areawide. Bradshaw && .LONG TERM... /Issued 232 PM CDT Sat Jun 15 2024/ /Sunday Night Onward/ After several days of quiet weather, an unsettled pattern is expected throughout this upcoming week. A shortwave disturbance is currently moving across the Southern Plains today and has shunted the upper ridge into Dixie Alley. To our northwest, an upper level longwave trough is moving onshore the Pacific Northwest. With the ridge to our east and trough to our west, moisture advection will be on the increase early this week in response to the south/southeast low-level flow atop the region. Guidance continues to highlight a weakness in the ridge, spanning from the Gulf of Mexico to the Southern Plains over the first half of this upcoming week. This weakness, coupled with the ample moisture and inherent instability, will allow for isolated showers and storms across our east/southeast zones both Monday and Tuesday. Lightning and heavy rain will be the main hazards. Over mid-late week, coverage of rain chances will be on the increase as a tropical disturbance in the Bay of Campeche moves over Mexico and South Texas. While rain chances will be higher to our south, isolated-scattered chances for showers and storms are expected during this time as the northern extent of the inverted shortwave trough will move across the region. Severe weather is not expected, however heavy rain and lightning will interrupt outdoor plans. Currently, forecast sounding storm motions of 30-40 kts will promote progressive movement and preclude a higher-end flood threat. Current most-likely 72 hour rainfall accumulations (Wed AM - Sat AM) show up to 1-1.5" across Central Texas with lower amounts further north. Thanks to those rain chances and cloudy skies, afternoon temperatures will peak in the 80s both Wednesday and Thursday. These temperatures are up to around 10 degrees below normal for this time of year. One particular point of interest will be Wednesday. Over the last three runs, the GFS has been consistent in the formation of a surface low in the Gulf that will move onshore and track westward across southern Central Texas during the day. If this solution were to occur, rainfall totals would increase across Central Texas and the ramp up the flooding threat. 15% of total ensemble guidance members are showing the northern inverted trough, with the majority of those solutions made up of GEFS and GEPS ensemble members. In short: while there is still uncertainty in what exactly will happen on Wednesday, we`ll need to keep a close eye in the coming days as mid- and short-range models begin to cover it. Prater && .AVIATION... /NEW/ /00Z TAFs/ VFR conditions will persist at all TAF sites through 00z Monday. Some patchy stratus may advect northward into the KACT area around 12z Sunday on the heels of good southerly low level flow, but am not confident at this point that coverage will be significant enough to include MVFR conditions at this site. Scattered fair weather cumulus clouds will develop at all TAF sites from 16z onward. A decent pressure gradient between a trough in eastern New Mexico and a high centered over the Lower Mississippi Valley will yield southerly winds sustained at 10-14 knots Sunday, with a few gusts to near 20 knots possible from midday onward.
