Area Forecast Discussion National Weather Service Fort Worth TX 322 PM CDT Fri Sep 20 2019 .LONG TERM... /Saturday night through Friday/ On Saturday evening, the center of the strongest ridging will be over the southeastern U.S., squashed on its western side by a landfalling tropical cyclone over northwest Mexico, and a shortwave trough moving through the Central Plains. A stream of high level moisture and strengthening westerly flow aloft associated with the shortwave will result in an elongated band of ascent across West Texas and into the Plains. Showers and thunderstorms are likely to be ongoing well off to our northwest Saturday night, but as the main shortwave swings eastward into Sunday morning, we may see one or more of these clusters expand into our area. This is most likely to occur through the day Sunday and we'll keep some 20-40% PoPs mainly across the north and northwest counties. With the shortwave departing late in the day Sunday, the upper ridging will spread back westward on Monday and we should see temperatures respond upward. A remnant weak frontal boundary should be draped across central or southern Oklahoma Monday afternoon and may serve as a focus for afternoon showers and thunderstorms. Some of this activity may develop south of the Red River during peak heating and we'll have some low PoPs across the northern half of the region during this time. The middle to latter part of the week will feature a cut off low over the southwest U.S. with ridging nudged a little farther eastward over the northern Gulf of Mexico. This will allow for a fairly robust southerly flow to remain in place keeping it warm and muggy through the end of the week. We'll maintain some low PoPs each afternoon through Thursday. This upper low to the west will likely eject into the Plains sometime on Friday, although at this time it looks like it may well too far to the north for an appreciable increase in rain chances. Dunn && .SHORT TERM... /Issued 1249 PM CDT Fri Sep 20 2019/ /Through Saturday afternoon/ Scattered showers and thunderstorms continue this afternoon near the Red River in the wake of Tropical Storm Imelda's remnant low. This convection is ongoing near where a surface dewpoint axis intersects a weak convergent boundary near the Red River. These cells are moving at a decent clip which should preclude flooding issues (we also have high flash flood guidance values given recent drought conditions), but rain gauge data does show that these cells are very efficient rainfall producers. Because of this, we will have watch for any training of showers/thunderstorms. To the southeast, additional showers and thunderstorms have developed around Palestine. We may see some coverage persist here as well, but the greater coverage should be to the north along the Red River. Convection should diminish after sunset as heating ends, and the boundary layer stabilizes. Tonight will be warm and muggy with lows in the mid 70s. Temperatures will stay up above seasonal normals as abundant Gulf stratus infiltrates the region. A stray shower or two is possible as is often the case in these warm air advection regimes, but coverage and amounts should stay light. Saturday will start off cloudy in the morning, but the sun should come out by afternoon, allowing highs to rise into the lower 90s. A few isolated showers, or perhaps a thunderstorm, will be possible during the afternoon as diurnal heating ramps up, but without any clear surface boundaries, coverage should remain sparse. 37 && .AVIATION... /Issued 1249 PM CDT Fri Sep 20 2019/ /18Z TAFs/ Concerns -- Convective potential at Metroplex TAF sites. Saturday morning MVFR cigs at all TAF sites. SHRA and a few TSRA are ongoing this afternoon near the Red River. A few of these may manage to sneak into the D10 TRACON area...but the greatest coverage should remain outside of the 25nm range rings. While TSRA is not impossible at any TAF sites...potential is too low to explicitly mention in TAFs...thus will only include VCSH with this issuance. While TSRA is not expected at terminals...coverage may increase enough this afternoon through 03Z to the north...resulting in impacts to the Bonham and Bowie arrival gates. Convection should decrease by 03Z. Overnight...another surge of Gulf stratus is expected...and MVFR cigs AOB FL025 are likely at all TAF sites...with cigs AOB FL015 likely at KACT. TEMPO IFR may be possible...especially at KACT...but will defer inclusion in TAFs to later issuances. Cigs should lift to VFR by 21/1800Z. 37 && .PRELIMINARY POINT TEMPS/POPS... Dallas-Ft.
