Area Forecast Discussion National Weather Service Fort Worth TX 357 PM CDT FRI AUG 12 2016 .DISCUSSION... North Texas is REALLY finishing up its August heat wave in style, with many spots enduring heat indices in the 110-115 range this afternoon. This has unambiguously been the hottest day of the summer for much of the region. Fortunately, our long-awaited cold front, while by no means arctic in nature, has now reached the northern fringes of our area, and promises to deliver relief to all of North and Central Texas by the end of the weekend. The generally "troughy" nature of the upper level flow pattern evolving over the Southern Plains should promote convection across most of the area this weekend, and to a lesser extent next week. Moisture will be abundant, yet there remains uncertainty as to whether the rainfall will be heavy enough and persistent enough in any one given area to produce more than incidental, localized flooding. This is the key forecast concern for the period. For tonight, we expect the cold front (and pre-frontal trough and outflow boundaries) to continue working south of I-20, with a shift to northerly winds everywhere by morning. The coverage of thunderstorms, which is currently extending from a Hamilton to Paris line, should shift southward this evening/overnight, coincident with the low level convergence afforded by the front/boundaries. We may have gone a bit too low on PoPs in the far southern counties tonight, especially if the convection starts to line out and become more progressive than expected. This will need to be monitored. Elsewhere, scattered PoPs should suffice. The thinking on Saturday's/early Sunday's PoP forecast has changed a bit, mainly due to the strong southward push of the front. With the convergence associated with this boundary now focused farther south in the central counties of Texas, we've backed off on the PoPs a bit from the I-20 corridor northward. Even so, weak isentropic lift well north of the front may warrant 40-50% chance pops. Lacking a strong focusing mechanism, we're not terribly worried about flash flood potential Saturday, though any individual cells may produce brief heavy rainfall and localized ponding/runoff concerns. The forecast picture gets pretty uncertain as we move into the latter part of the weekend, and that's due to the lack of true clarity on the track of the Louisiana upper low. Without a doubt the favored areas for rainfall from Sunday into Monday will be over our eastern counties, in closer proximity to the slow moving upper low. Assuming this warm-core vort center stays east of our area, we think the threat of flash flooding will not be that great through Monday. However, any westward deviation of this low up through the I-35 corridor could rapidly increase the threat. For now, we've held off on a Flash Flood Watch, owing to these uncertainties in location and timing. As we progress from Monday into the middle/latter portions of the week, the large scale weakness in the height field should gradually shift eastward toward the Lower Mississippi Valley. This transition looks like it will be slow to unfold, however, and thus we'll continue with scattered PoPs for most of North and Central Texas right on through the week - highest in the eastern counties. With thicknesses remaining in check, coupled with clouds and scattered rain, we can expect daytime readings to remain below seasonal norms through the week. Bradshaw && .AVIATION... /ISSUED 1254 PM CDT FRI AUG 12 2016/ /18Z TAFs/ Concerns...Convective potential and wind shift. A front is making its way towards North and Central Texas but the winds ahead of the front are shifting to the west with a pre-frontal trough. The DFW area airports should see west winds at 10 kts or less by 19Z and KACT will take a few more hours to veer to the west. The winds will become more northerly this evening and tonight as the true front arrives and north winds will prevail through this valid TAF period. With temperatures already in the upper 90s and around 100 degrees, isolated to scattered showers and thunderstorms are expected to increase in numbers as the afternoon continues on and into the evening hours. Will continue with VCTS from 20-21Z through 05Z at all the TAF sites, and then keep a mention of VCSH through 09Z. Confidence in convection trends after 02Z is lower than the afternoon hours and adjustments to trends may be required for late evening and overnight hours. The front will likely stall just south of KACT on Saturday where a better focus for convection may be Saturday afternoon. Will have no mention of convection in the extended portion of the KDFW TAF at this time but reassess new model guidance for isolated storms developing in the afternoon hours near the DFW area. May need to include VCTS for KACT Saturday afternoon as that time frame comes into the TAF period. Any storms this afternoon and Saturday afternoon will have a threat for damaging downburst winds and localized heavy rainfall that would impact airport operations.
