Area Forecast Discussion National Weather Service Fort Worth TX 120 PM CDT Tue Sep 8 2020 .SHORT TERM... /NEW/ /This afternoon through Wednesday/ This afternoon will be warm and muggy across the region with breezy south and southeast winds. Isolated to scattered rain and thunderstorms will continue to move north through the moisture- rich environment, aided by a shortwave moving through southwest flow aloft. Severe storms are still not expected due to weak deep layer wind shear, but stronger storms may produce gusty winds reaching 40-50 mph. For the afternoon hours, have increased PoPs across most of the region accounting for radar trends the past few hours, and for showers and storms developing across the region within the past hour. Afternoon convection should diminish this evening with the loss of daytime heating, and a few hours lull in rain/storm activity is expected before it picks up again early Wednesday morning. This next increase in convection will occur as additional shortwaves move over the region. Most of the overnight/early morning rain will be west of Interstate 35/35W with more isolated activity possible east of I-35. This activity will again be cruising north along southerly flow in the lower to mid levels of the atmosphere. Severe storms are not expected but brief heavy rainfall will be possible. Overnight conditions will be muggy with low temperatures in the 70s across most of the region. As the sun starts to crest the horizon Wednesday morning, the much anticipated cold front will be sneaking its way into our northwestern counties. In this area, temperatures will likely drop in the 60s before the time period of minimum recorded temperature ends at 10 am. Then, temperatures will likely be falling for much of the morning hours in our northwestern counties, remaining in the 50s most of the day. The front will continue to ease east all day, finally reaching the I-35 corridor late in the day. Ahead of the front, afternoon highs will reach the mid and upper 80s with humid conditions. For frontal timing, temperature and dewpoint trends, and high temperatures, have continued to side with the NAM or a NAM-Superblend model blend. Rain will continue across mainly the western half of the region during the day on Wednesday, and it will be most expansive behind the front. Severe weather is not expected but heavy rainfall resulting in flooding will be possible, mainly behind the front. The front will continue an eastward progress Wednesday night into Thursday. JLDunn && .LONG TERM... /Issued 313 AM CDT Tue Sep 8 2020/ /Late Week Through Next Monday/ An unsettled, early Fall-like pattern will continue through the weekend with temperatures generally below seasonal normals. Similar to the short-term forecast, stuck with a big lean toward the more progressive NAM12 through Thursday, which was handling the initial shallow colder airmass better across particularly the western and central counties. This makes meteorological sense considering the abundant cloud cover and convective rain chances combined with the low level CAA across those areas. These forecasts are always tricky considering we're still in early September, but with the cut off mid level low over the Four Corners/Central Rockies and subsequent mid level impulses moving southwest to northeast, mostly cloudy and showery conditions will continue across the region. Though a strong storm or two Thursday afternoon can't be ruled out, we do not expected severe weather or any major impacts outside of heavy downpours and occasional lightning strikes. Temperatures across the board will be cooler than what is normally seen this time of year (lows around 70 and highs around 90). The cut off low and lower than normal height anomalies to our northwest look to finally get picked up and lifted east across the Plains as we enter the weekend. This change within the medium range ensembles will be due to height falls occurring across the Northern Rockies into Western Canada Friday into Saturday. Mid level flow over our area and the Southern Plains thus becomes less amplified with slight height rises these two days with likely our warmest days of the coming week, but really not too bad. With partly sunny skies returning, look for highs primarily in the 80s, though a few areas across eastern Central Texas may push to around 90 degrees. A weakness aloft will remain to keep subsidence to a minimum, thus low chances of showers and non-severe thunderstorms will continue each day. Column moisture will remain above the 90th percentile per model forecast PWAT values, so can't rule out some brief heavy downpours and even spotty minor flooding considering soils remain fairly moist to near saturation. If you don't mind the occasionally wet and cooler-than-normal weather conditions, then I have more good news for you! The now open Plains/Upper Midwest trough moves east over the Mississippi/Ohio Valleys and Great Lakes region Sunday into the early part of next week. There will be enough mid level support from the northwest flow aloft in wake of this week's system to provide a reinforcing push of cooler air into the area. In addition, a semi-detached shortwave trough will accompany this front to provide scattered to broken cloud cover and low rain chances across much of the area. It appears the better chances will occur across Central Texas, where richer PWAT values in excess of 1.5 inches will persist. With recent rainfall already received and the forecast rain chances off and on the next 7-10 days, this should help to improve the lingering and spotty moderate to severe drought conditions that remain across western Central Texas. Meanwhile, impacts on temperatures will continue with lows ranging from the mid 60s to lower 70s, while highs average in the lower to mid 80s. Continue to stay on top of our future forecasts, as weather trends become more clear in the coming days. 05/ && .AVIATION... /NEW/ /18Z TAFs/ Concerns...Convective potential this afternoon and Wednesday. Return of MVFR cigs Wednesday morning. VFR cigs between 3-5 kft are being reported at all the TAF sites at this hour, and VFR cigs are expected to prevail through tonight. However, showers and storms are developing across the region, and these will cause an impact to aviation operations through about 01-02Z. Severe weather is not expected but gusty winds are possible in the stronger storms. Southeast winds are expected to prevail between 10-15 kts with gusts nearing 20 kts, but outflow boundaries and/or storms themselves at an area airport may cause sudden wind shifts. There should be a lull in the convective activity overnight, but showers and storms return to the region early Wednesday morning, impacting KACT first and gradually spreading north into the DFW Metroplex. Severe weather is not expected but lighting and heavy rainfall causing reduced visibilities will be the main hazards to aviation. This rain activity will continue for much of the day on Wednesday, but could remain mainly west of the TAF sites until late in the day and/or Wednesday night. MVFR cigs between 1-3 kft will also move into the I-35 corridor Wednesday morning and remain until about midday. Finally, a cold front will approach the TAF sites around 00Z Wednesday causing a wind shift that is just beyond the scope of this TAF period. JLDunn && .PRELIMINARY POINT TEMPS/POPS... Dallas-Ft.
