Area Forecast Discussion National Weather Service Fort Worth TX 151 PM CDT Fri Jun 19 2020 .SHORT TERM... /Issued 132 PM CDT Fri Jun 19 2020/ /Through Saturday Afternoon/ Abundant moisture has now worked its way into North and Central Texas, evident by GOES-16 derived PWAT values. West of I-35, PW values range from around 1.5-1.7”, with slightly lower amounts east of I-35. A strong low-level jet was in place earlier today, allowing for a complex of storms to gradually build southward. This complex of storms is expected to continue to back-build through the afternoon hours, potentially impacting the northwestern counties of North Texas. There remains uncertainty just how far south storms will back-build given models have been struggling to correctly depict the ongoing convection. This is likely due to the weakening of the low-level jet reducing the amount of ascent and moisture moving atop the remnant outflow boundary. Given the thermodynamic environment and mesoscale features in place just northwest of our region, additional thunderstorms are expected to develop as we approach peak-heating. This is likely to reinvigorate the outflow boundary, potentially pushing it farther south into northwestern portions of North Texas. Instability will likely be around 2500 J/kg, with about 20 kts of effective bulk shear. A strong storm or two can’t be ruled out, with small hail and strong winds the main threats this afternoon. For tonight, we’ll have to watch the dryline convection expected to become linear as it moves eastward. Given the best kinematics are expected to stay west of I-35, as the line approaches the I-35 corridor, a gradual weakening is expected. The main hazard overnight will be strong winds and lightning. Storms are expected to gradually dissipate during the early Saturday morning hours. A rather unstable atmosphere will remain in place on Saturday as another weak shortwave moves across the region. Currently, guidance is suggesting another round of showers and storms moving across the Red River Valley in the afternoon. Therefore, precipitation will be advertised in the aforementioned area. Elsewhere, confidence in precipitation remains too low to add to the forecast. High temperatures both today and tomorrow will be mostly in the lower 90s, with a few isolated spots remaining in the upper 80s. Hernandez && .LONG TERM... /NEW/ /Saturday night onward/ The long-term period will be more active compared to the last seven days. The 500 mb pattern this morning is characterized by a deep trough over the western CONUS with a ridge stretched across the interior CONUS. This trough will make its way into the central CONUS over the next couple of days, bringing a northwest flow pattern into North and Central Texas. These northwest flow regimes often bring increased thunderstorm chances in the form of nocturnal convective complexes that originate on the High Plains of Colorado, Kansas, and Oklahoma, and make their way southeast towards North Texas. While these patterns typically pose little in the way of a significant severe threat, a low severe threat (in the form of damaging winds) is still possible, as is locally heavy rainfall. Spatially, North Texas, especially close to the Red River, is the favored area for the highest thunderstorm chances and rainfall accumulations during these patterns. The first such convective complex looks to come Saturday night into early Sunday morning. Most of the model guidance, except for the NAM, keeps this complex up in Oklahoma or very near the Red River. The NAM brings the complex through the Metroplex, but appears to be an outlier for now. Sunday afternoon, we may see some diurnally-driven convection east of I-45. This is another theme in these northwest flow patterns: we can sometimes get diurnally-driven convection near remnant outflow boundaries as the larger nocturnal convective complexes dissipate during the morning hours. Trying to determine where these outflow boundaries will set up is difficult to do more than several hours out -- forget several days out. Nevertheless, with this first round on Sunday, higher PoPs would be favored towards the east. The next round of thunderstorms looks to come late Tuesday. The GFS and ECMWF both show QPF across much of North Texas during this timeframe, but vary on the exact timing. Right now, have painted chance PoPs across much of the region, but these will likely need to be increased as confidence improves on the timing/position of the most widespread precipitation. Likely PoPs have already been included in our northeastern counties where confidence is the highest. Some areas could pick up half an inch of rain or more with this round. It is also worth mentioning that because of the thunderstorms and trailing cloud cover, we are likely to see below normal temperatures. The GFS MOS actually has highs in the low 80s on Tuesday. This would be wonderful for late June, but is on the cooler end of the guidance. Still, highs will probably stay in the 80s for many locations. Wednesday should see another round of diurnally-driven convection near a remnant outflow boundary which will likely be somewhere east of I-45. Again, forecasting the position of this boundary and the resultant convection is very difficult. The good news is, this type of convection does not typically result in an all-day washout. Be prepared for some rain and lightning, but it should not last long at any particular location. Towards the end of the week, the northwest flow will weaken somewhat, but with the ridge remaining displaced to the southwest and atmospheric moisture remaining elevated, we should see continued chances for afternoon showers/thunderstorms across parts of the area. Godwin && .AVIATION... /Issued 132 PM CDT Fri Jun 19 2020/ /18 TAFs/ VFR is currently ongoing across the region as southerly breezy winds persist. There is a complex of thunderstorms currently impacting Central OK and northwestern TX. This complex is expected to attempt to build southward, potentially impacting the Bowie corner post later this afternoon. At this time, thunderstorm probability remains low given storms are expected to weaken before reaching the Dallas/Fort Worth Metroplex. Our attention will then turn to the west, across the Texas Panhandle, as another line of storms develops. This convection is expected to migrate eastward through the afternoon/evening, reaching the Dallas/Fort Worth Metroplex by around 06Z. A TEMPO group has been added as confidence in thunderstorm probability has increased. A brief wind shift will be possible as the storms move across, but should return to southerly winds shortly after. An MVFR deck will build northward out of the coastal region through the night, likely impacting KACT early Saturday morning. Southerly winds will remain in place through the night and into tomorrow morning. As mixing of the lower levels occurs, cig heights are expected to gradually increase and scatter out. For Waco, VFR looks likely once again tomorrow afternoon. Hernandez && .PRELIMINARY POINT TEMPS/POPS... Dallas-Ft.
