Area Forecast Discussion National Weather Service Fort Worth TX 342 PM CDT Thu Aug 27 2020 .SHORT TERM... /Issued 212 PM CDT Thu Aug 27 2020/ /Through Friday/ While most of the region has remained in the subsidence part of the now Tropical Storm Laura, we have seen a slight uptick in the radar echoes showing some light precip mainly along the Red River. We will continue to see scattered showers and storms through the afternoon and early evening with enough instability and lift in place. Still, overall coverage should remain around 20-30%. PoPs decrease tonight as the atmosphere stabilizes and the remnants of Laura moves further away. The only exception will be across the far eastern/southeastern counties, where lingering showers/storms may develop overnight and again Friday afternoon. Overnight temperatures will stay again in the 70s. Friday will be much hotter for us, as much drier and warmer airmass travel across the southern plains. Highs in the upper 90s to near 104 degrees and heat indices between 104-109 degrees. A Heat Advisory will be in effect starting Friday afternoon across all North and Central TX. Sanchez && .LONG TERM... /NEW/ /Saturday Onward/ Unpleasant heat will continue into the weekend. Highs on Saturday will be similar to those on Friday, but dewpoints aren't expected to mix out as much. This means heat index values will be a few degrees higher, and some isolated spots could even briefly touch Excessive Heat Warning criteria with heat index values exceeding 110. Late Saturday afternoon, a weak front is expected to approach the Red River which will likely stall just to our north. This boundary should be capable of initiating convection, some of which may move into our north/northwestern zones Saturday evening or night. Heights aloft will be a bit lower on Sunday as the upper ridge flattens, and resultant temperatures could be a few degrees cooler as a result. Some areas may still experience borderline Heat Advisory again Sunday afternoon with heat index readings near 105. Additional isolated convection will be possible in the afternoon hours on Sunday in the vicinity of the old frontal boundary. Faster zonal flow aloft will become established by Monday, with a few disturbances rippling through during the first half of the week. Latest guidance has come into better agreement regarding the potential for a slightly stronger front to move into the forecast area during the day 5-7 time period. There is still a wide envelope of ensemble solutions despite recent operational model runs suggesting this front will make it into our forecast area. It is worth noting that some ensemble members keep this boundary completely north of the area. When (if) this boundary does arrive, it should result in some decent rain chances given ample moisture and instability in place. In fact, with the stronger flow aloft, a couple organized strong or severe storms wouldn't be out of the question. However, this potential remains quite uncertain given it's still several days into the forecast period. Otherwise, this front would have the potential to cool off parts of North Texas by several degrees. With much uncertainty in the front's timing/placement, have not advertised a significant decrease in forecast high temperatures just yet. It is possible however, that parts of North Texas could experience highs in the mid or upper 80s behind this boundary, especially if convection or cloud cover exists through the peak heating hours. This scenario would be just a brief respite from summer with highs returning to the upper 90s by the end of the week. -Stalley && .AVIATION... /Issued 212 PM CDT Thu Aug 27 2020/ /18z TAFs/ Concerns...Isolated to scattered thunderstorms this afternoon. North/northeasterly winds becoming south Friday night. Tropical Storm Laura continues to move northward near the Louisiana and Arkansas border as of this afternoon. We can't rule a few showers and storms across parts of North and Central TX where the atmosphere remains fairly unstable/uncapped. Coverage is expected to be fairly isolated/scattered and diminish around 00-01Z. Opted to keep the mention of VCTS across all TAF sites between 20-01Z. Any activity should dissipate this evening as Laura continues to track northward across Arkansas. Tonight and tomorrow...VFR cigs with some high clouds. Winds will eventually shift to the south after midnight at around 5-10kts. Sanchez && .PRELIMINARY POINT TEMPS/POPS... Dallas-Ft.
