946 FXUS64 KFWD 170752 AFDFWD Area Forecast Discussion National Weather Service Fort Worth TX 252 AM CDT Mon Jun 17 2024 ...New Long Term... .SHORT TERM... /Issued 1248 AM CDT Mon Jun 17 2024/ /Through Tuesday/ Tropical moisture from the Gulf will be funneled northward within strengthening southeasterly low-level flow through the first half of the week, with PW values progressively increasing. This will contribute to morning stratus intrusions, followed by scattered shower and thunderstorm development during the afternoon. Rain chances both today and Tuesday will be highest across the southeast, tapering off to near zero farther to the northwest. Given the rather robust southeasterly low-level flow of as much as 30-40 kts, a fairly active seabreeze feature could become established. In this case, convection could certainly spread as far north as the DFW Metroplex by late afternoon. Showers and storms will cease with loss of heating with tranquil weather overnight. While this activity would be incapable of producing severe weather, brief heavy downpours and some gusty winds are certainly possible. Thanks to increased moisture content, cloud cover, and the presence of some rain-cooled air, high temperatures will only reach the low to mid 90s across most of the area both today and tomorrow. -Stalley && .LONG TERM... /NEW/ /Tuesday Night Onward/ Rain showers will be on the increase across Central Texas late Tuesday night as a plume of deep tropical moisture surges northwest into the area. The tropical disturbance responsible for the precipitation will be in the process of moving inland across South Texas, placing North and Central Texas within a zone of strong warm/moist air advection. Showers will spread northwest through the forecast area during the day Wednesday, with occasional thunderstorms possible in the afternoon as surface instability is attained. The latest model guidance indicates that the axis of exceptionally high moisture content will be along and southwest of a line from roughly Wichita Falls to Palestine, where 2.25" PWATs are a good possibility (around 150% of normal). This would include pretty much all of Central Texas and western portions of the DFW Metroplex, and would be the most likely area where training showers and storms could produce a threat for flooding. It is possible that a southeast to northwest rain band could set up and continue into the night, enhancing the flood threat on a local scale. It is too soon to bank on any one scenario, but good to keep in mind that locally higher amounts (above the generally 1 to 3 inches forecast) of rain are possible somewhere southwest of the aforementioned geographical line. Rainfall totals (and the threat for flooding) northeast of this line would be significantly less. The exact location of the moist axis could also shift one way or another, either decreasing or increasing the threat for locally heavy rain. Unfortunately the bust potential is also quite high, because if the system were to wrap up over the Gulf and become more intense than currently forecast, precipitation might become more confined to South Texas while North/Central Texas becomes displaced too far north in the subsident zone. We should be able to refine these and other details over the next 48 hours. Whatever the case, Wednesday night precipitation will exit from east to west on Thursday as the tropical system progresses west across Mexico. A mid level ridge will re-strengthen overhead in its wake, ending rain chances and bringing typical summer weather in time for the weekend. Another easterly wave will create at least a slight chance of rain during the early to middle part of next week. 30 && .AVIATION... /Issued 1248 AM CDT Mon Jun 17 2024/ /06z TAFs/ An intrusion of MVFR stratus is likely to affect some of the airports this morning, although the coverage and longevity of these low cigs is still uncertain at this time. After scattering to VFR occurs by this afternoon, isolated shower and thunderstorm activity will spread northwestward into parts of East and Central Texas, perhaps affecting the Waco TAF site and even parts of D10 through the late afternoon hours. The potential for convection at the DFW Metroplex TAF sites is too low to currently mention in the TAFs, but there is a small chance that a consolidated seabreeze could allow for convection to spread into the TAF sites prior to dissipating this evening. Otherwise, a persistent southeast breeze of 10-15 kts with gusts near 25 kts will prevail through the period. -Stalley && .PRELIMINARY POINT TEMPS/POPS... Dallas-Ft.
