I'm moving back east from Arizona this weekend, and plans are to be in Amarillo Saturday night and central/east Missouri Sunday night. Am I good, or might I see some action?

Quincy Posted May 22 Author Share Posted May 22 Mean troughing across the Northwest will allow several disturbances to rotate around its base over the next few days. Expecte severe threats to continue into the weekend from the Plains into parts of the Midwest/Mid-South. Today: A sagging cold front, convectively reinforced across Oklahoma and vicinity as of midday, will be the focus for severe thunderstorm activity today. Elevated supercells across central Oklahoma earlier this morning will pose the initial severe threat from southeastern Oklahoma into Arkansas. The environment south of the front, across much of Texas toward the Arklatex, is already strongly to extremely unstable. With forcing ahead of the cold front impinging on rich low level moisture in place, widespread convective initiation is likely by early afternoon. Although deep layer shear is more than sufficient for organized severe convection, wind profiles suggest mixed storm modes with numerous cell interactions. A few initial supercells are probable across central Texas, SW toward the Rio Grande, but even these storms should tend to grow upscale fairly quickly. Thursday: Moisture recovery may take a while due to convective overturning from today/tonight. The most likely area for widespread convection during the afternoon will be across the Dakotas into Nebraska, as an upper level disturbance ejects out of the Northern Rockies. A more conditional severe risk may evolve near a dryline from Kansas, southward into western Oklahoma and west-central Texas. Models vary with convective coverage, but at least isolated convective initiation seems possible. As a cold front surges southeast Thursday night, it should overtake the dryline in Kansas and shunt appreciable low level moisture south across the Southern Plains. Friday: A shortwave is progged to eject from the Central Plains toward the Middle Mississippi Valley. This combined with the surging cold front should push the severe threat into parts of the Midwest, southward toward the Arkansas vicinity. Some severe thunderstorms may once again impact parts of Texas, but with several days of convective overturning and moisture getting pushed south, the threat may be limited.

Powerball Posted May 22 Share Posted May 22 The early initiation with the front surging southward faster than expected, as well as the lack of surface heating beforehand (since we were socked in low clouds), kind of did DFW in as far as not realizing the full potential with this setup.But it does seem there were plenty of low-end severe hail reports in the northern suburbs (quarter to half-dollar size) thanks to ample elevated instability and vertical shear. So while underperforming, not a total bust.Also, lightning just struck a transformer here and the power was out for about 15 seconds (it's back on now) Link to comment Share on other sites More sharing options...

Quincy Posted May 23 Author Share Posted May 23 With regards to the Southern Plains severe threat today: Focus is along the dryline, although there are mixed signals about storm coverage and longevity. Large scale forcing is modest, over the NW Oklahoma/Kansas portion of the region, but height falls will be somewhat more than areas to the south, where deep layer flow will be stronger. Midday convection across North Texas complicates the forecast to some degree. The western flank may be a focus for intense high precipitation supercell development later. The middle area, SW Oklahoma into NW Texas may be where the best overlap of ingredients exists. This is where there seems to be the most model agreement, although augmentation of the environment due to downstream convection cannot be overlooked. Over western Kansas, there may be a relative minimum in convective coverage. CAMs are mostly void of convection, although a few NAM/WRF members and occasional HRRR runs suggest at isolated convective initiation, somewhere near Dodge City, perhaps near where an effective warm front intersects the dryline. 2 2 Link to comment Share on other sites More sharing options...

cheese007 Posted May 24 Share Posted May 24 Mesoscale Discussion 0918 NWS Storm Prediction Center Norman OK 0733 PM CDT Thu May 23 2024 Areas affected...Southwestern Oklahoma Concerning...Tornado Watch 295... Valid 240033Z - 240130Z The severe weather threat for Tornado Watch 295 continues. SUMMARY...A dangerous, tornadic supercell is expected to continue slowly moving ESE across Jackson County, and as far south as the Red River over the next hour. DISCUSSION...Recent radar imagery from KFDR indicates VROT has increased to 90-105 kt within an ongoing, confirmed tornado located just west of Olustee, OK (southwest of Altus). The extremely unstable environment downstream of this strong to violent tornado will continue to favor tornadogensis, where SSE sustained surface winds around 20 to 25 kt will enhance localized surface vorticity. ..Barnes.. 05/24/2024 ...Please see www.spc.noaa.gov for graphic product...
