  1. The cell//storm south of Dallas seems to be ramping up more. Looks like the LLJ kicked in there
  2. Looks like Nick might be close to something https://livestormchasing.com/chasers/nick.busby
  3. Looks like the SPC is not out right sold on sig tornadoes with this setup, but is mentioning as more a possibility. Given rich boundary-layer moisture coupled with the large MLCAPE, there is concern for at least conditional significant tornado potential across a portion of north TX into southeast OK. If upscale growth occurs too quickly, this may not be realized, but have highlighted a corridor of enhanced tornado potential in this region. Otherwise, upscale growth will occur at some point this evening rendering a predominant severe wind threat spreading east-northeast towards the Mid-South through tonight.
  4. NWS Fort Worth @NWSFortWorth · 57m The Fort Worth radar (KFWS) is being taken down for a few hours to replace a bearing before the storms develop. It should return to service by 3PM today, if not sooner. #dfwwx #txwx
  5. Pete Delkus is reporting 2 and 1/2 inch hail (for the Dallas storm)
  6. NWS Fort Worth @NWSFortWorth · 3m 8:27 PM - Circulation is near Blue Mound right now but has become less defined. #dfwwx
  7. NWS Fort Worth @NWSFortWorth · 1m Tornado Warning including North Richland Hills TX, Euless TX, Bedford TX until 9:00 PM CDT
  8. Yup. SPC originally had dfw included in the MD discussion and pulled it back. This was the latest from FWD Area Forecast Discussion National Weather Service Fort Worth TX 203 PM CDT Wed Apr 28 2021 ...New Short Term... .SHORT TERM... /NEW/ /This afternoon through Thursday/ Scattered showers and storms continue to move across parts of North TX. While intensity and coverage has decreased over the last couple of hours, there`s still some lightning with some of the storms. This activity will continue to move out of our area....as renewed showers and storms develop later this afternoon and evening. Latest high-res guidance continues to show this development with some of the storms quickly becoming strong or severe. With plenty of low-level moisture, instability, and shear the environment definitely support this activity. Now, one thing that remains uncertain is the influence of the morning convection to the coverage of severe storms. Right now, most areas across the northwest and along the Red River are pretty stable with the deep coverage of clouds. However, we`ve been seeing some clouds clearing to our southwest, just east of the dryline that could result in the first round of re-development later this afternoon. If I were to pick, the first area to monitor will be to our west/southwest (along/south I-20 and west of I-35). As storms develop and continue to move northeastward, they will be capable of producing large hail, isolated damaging wind gusts, and a few tornadoes. A Tornado Watch has been issued for the counties west of the DFW Metroplex until 02Z, and additional watches may be needed this evening. Still, the coverage of severe weather will depend on how much the airmass is able to destabilize. The initial development will likely remain scattered, but as they move eastward this evening they will likely merge into a cluster or line. While the severe potential remains tonight, there will be a transition to a heavy rain flooding threat through the overnight hours for all North and Central TX. We`re still expecting rainfall totals through Thursday around 1-3" over most locations, but there could be isolated instances of 4-6"+ in some areas. A Flash Flood Watch might be needed if confidence in widespread higher precip totals increases. Showers and storms will continue into Thursday as the low level pressure system moves across Central TX. The potential for lightning and strong/severe weather will shift to the east/southeast by Thursday afternoon.
  9. SPC in the latest update showed a major shift to the west
  10. SPC upgraded 4/24 Saturday system to an enhanced with 10% hatched tornado probabilities in the latest outlook
  11. SPC D5 15% highlighted outlook Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0354 AM CDT Mon Apr 19 2021 ..DISCUSSION... A shortwave trough should move eastward across the Southwest on Day 4/Thursday. Low-level moisture return appears likely across parts of the southern Plains into Day 5/Friday, as lee cyclogenesis occurs across the southern High Plains ahead of the approaching upper trough. Run-to-run consistency over the past several runs of the deterministic ECMWF lends confidence that the shortwave trough should eject eastward over the southern Plains on Friday. Increasing low-level moisture to the east of a dryline/cold front and steep mid-level lapse rates should support at least moderate instability in a corridor across parts of OK and TX by Friday afternoon. Strong mid-level flow and related deep-layer shear appear more than sufficient for organized severe storms, including supercells. As mid-level height falls/ascent overspread the warm sector, robust convective development should occur, with at least isolated severe storms potentially spreading eastward towards southeast TX Friday evening/night. Confidence in this scenario occurring has increased enough to include a 15% severe area for Friday.
