  1. Slight risk added for the 13th as of today, with a large expansion of the risk area + hatching added for the 14th. Below is the discussion for the latter SPC AC 120731 Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0231 AM CDT Tue Mar 12 2024 Valid 141200Z - 151200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM THE MIDDLE MISSISSIPPI VALLEY INTO EASTERN OKLAHOMA...EAST TEXAS...AND THE LOWER MISSISSIPPI VALLEY... ...SUMMARY... Strong to severe thunderstorms are possible across a large area from the Middle Mississippi Valley into eastern Oklahoma, East Texas, and the Lower Mississippi Valley on Thursday. ...Synopsis... A surface low is forecast to be over the NE/IA/MO border vicinity early Thursday morning, with a cold front extending southwestward from this low across eastern KS and central OK into the TX Hill Country. An expansive warm sector is expected to be in place east of this cold front, from the Mid MS Valley into the southern Plains and Lower MS Valley early Thursday morning, supported by the previous days' return flow. Showers and thunderstorms may be ongoing in the vicinity of a warm front extending north-northeastward from the surface low, but much of the warm sector is currently expected to be free from any early period storms. This broad warm sector is expected to destabilize throughout the day with two primary corridors of severe thunderstorms potential, one near the surface low from southern IA/northern MO into west-central IL and another farther south from eastern OK and east TX into LA and AR. ...Southern IA/Northern MO/West-Central IL... Upper 50s dewpoints are expected south of the warm front throughout the period. Despite this somewhat modest low-level moisture, moderate to strong buoyancy is still anticipated early in the afternoon as surface temperatures climb into the low 70s, supported by cold mid-level temperatures and resulting steep mid-level lapse rates. Low-level convergence near the surface low and warm front will likely result in convective initiation amid vertical wind profiles that support supercells. There may be a tendency for storms to move north of the warm front over time, but enough residence in the warm sector is anticipated for some storms to reach maturity. Any mature supercells would be capable of all severe hazards, including tornadoes, strong gusts, and very large hail. ...Eastern OK and East TX into LA and AR... Weak surface troughing will likely interact with an increasingly unstable airmass across the region during the afternoon, with convective initiation anticipated around 18Z across southeast OK and northeast TX. Given robust buoyancy and moderate vertical shear, initial development will likely be supercellular and capable of all severe hazards, including very large hail. How the convection evolves after the initial more discrete storms remains uncertain, with some potential for development into more linear structures given the front-parallel deep-layer vertical shear. If upscale growth is realized, the resulting convective line would then push eastward into AR and LA, with some potential for damaging gusts. ..Mosier.. 03/12/2024

  3. SPC highlighting a multi-day severe event running from March 7th through the 9th. 15% contours have already been introduced for D4 into D5 with less certainty re: D6 ZCZC SPCSWOD48 ALL ACUS48 KWNS 041000 SPC AC 041000 Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0400 AM CST Mon Mar 04 2024 Valid 071200Z - 121200Z ...DISCUSSION... A multi-day severe event appears increasingly probable for the latter portion of this week into the early weekend. For Day 4/Thursday, a 15% severe area has been introduced across parts of TX into the lower MS Valley for mainly a large hail threat Thursday night into early Friday morning. A southern-stream upper trough is forecast to eject across the Southwest/northern Mexico into the southern Plains in this time frame. Steep mid-level lapse rates should overspread the gradually destabilizing warm sector, with the ECMWF and its ensemble in particular suggesting that ample MUCAPE will be available Thursday night across parts of north-central into east TX. Any thunderstorms that can initiate in the strengthening low-level warm advection regime across this region should pose a threat for large hail given ample cloud-bearing shear to support elevated supercells. Some of this activity could become near-surface-based towards 12Z Friday morning across the lower MS Valley as surface dewpoints quickly increase into the mid/upper 60s. The severe threat will likely continue into Day 5/Friday, where a 15% severe area has been introduced from east TX into the lower MS Valley and parts of the central Gulf Coast states. There is still some uncertainty in guidance regarding the ejection of the upper trough and placement of related surface features. Regardless, there is enough agreement that rich low-level moisture will advance inland across these areas to support a threat for surface-based convection ahead of whatever activity develops across north-central TX late Thursday night into early Friday morning. Forecast soundings from both the GFS and ECMWF show strong effective bulk shear that will support the potential for supercells producing large hail, damaging winds, and tornadoes. Convection may also grow upscale into bowing line segments while continuing to pose a threat for severe/damaging winds and a few tornadoes. The main uncertainty remains how far inland/north the warm sector will be able to advance, particularly across MS/AL. For now, have opted to remain conservative with the northward extent of the 15% severe area by highlighting where at least mid 60s surface dewpoints appear probable. Some severe risk may persist into Day 6/Saturday across parts of the Southeast towards the Carolinas. However, model guidance shows substantial spread in the evolution of the upper trough at this extended time frame. Convection may also have a tendency to outpace the developing warm sector with time. While parts of FL/GA/SC/NC will be monitored for possible inclusion in a 15% severe area in later outlooks, predictability for early this weekend remains too low at this time. ..Gleason.. 03/04/2024

  5. Big D1 ENH stretching from SE TX to the Alabama border with a sigtor hatch to match. Already having a storm ongoing in TX that's been tornado warned for quite some time SPC AC 111627 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1027 AM CST Sun Feb 11 2024 Valid 111630Z - 121200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON INTO EARLY TONIGHT FROM SOUTHEAST TX TO CENTRAL LA/MS... ...SUMMARY... A few tornadoes, some of which could be strong, very large hail to the size of baseballs, and isolated wind damage are all expected through tonight from southeast Texas into central parts of Louisiana and Mississippi. More isolated severe storms will be possible into Alabama and western Georgia. ...Southeast TX today to central LA/MS/AL through tonight... A midlevel shortwave trough over west TX will continue eastward over TX/OK through tonight. Associated surface cyclogenesis is expected today along a baroclinic zone across southeast TX, and the wave cyclone will subsequently move east-northeastward into MS tonight. Ongoing/elevated supercells may persist across northern LA through midday/early afternoon along the northeast edge of the steeper midlevel lapse rates and larger buoyancy, with large hail/damaging winds possible. The primary severe threat should evolve from the ongoing southeast TX supercells, and with additional storm development near the warm front through the afternoon/evening into LA/MS. A moist/unstable warm sector with upper 60s dewpoints and temperatures warming into the 70s is already established along and south of the baroclinic zone across southeast TX into southern LA/MS. The boundary should move a little northward today as a warm front and provide a focus for additional severe storms through tonight as far east as MS/AL. The steep midlevel lapse rates (7.5-8.5 C/km) in 12z observed soundings and long hodographs will favor isolated very large hail up to 2.5-2.75" diameter with the more intense supercells today from southeast TX into central LA, and by this evening into central MS. Low-level shear/hodograph curvature will be sufficient for tornadic supercells, with some potential for a couple of strong tornadoes in this same corridor. ..Thompson/Wendt.. 02/11/2024 CLICK TO GET WUUS01 PTSDY1 PRODUCT NOTE: THE NEXT DAY 1 OUTLOOK IS SCHEDULED BY 2000Z CURRENT UTC TIME: 1648Z (10:48AM), RELOAD THIS PAGE TO UPDATE THE TIME

  7. Per WFAA DFW mamaged 1.3 inches for the event, which is roughly the seasonal average. Not bad at all for a lake effect event here!
  8. Surprised to see a D1 hatched ENH centered on the ArkLaTex this morning. Then I saw it was Broyles and it made more sense. Still worth watching I guess... SPC AC 110558 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1158 PM CST Wed Jan 10 2024 Valid 111200Z - 121200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE ARK-LA-TEX... ...SUMMARY... Severe thunderstorms, associated with tornadoes, wind damage and isolated large hail, are likely to develop across parts of the Ark-La-Tex this evening into the overnight. A severe threat is also expected to develop further south across parts of east Texas and Louisiana. ...Ark-La-Tex... An impressive upper-level system will translate quickly eastward through the Desert Southwest today, reaching the southern Plains this evening. Within the base of the trough, a 100 to 120 knot mid-level jet will move through west Texas this evening, as the nose of the jet overspreads the Ark-La-Tex. Ahead of the system, moisture will return northward across east Texas and Louisiana, with the nose of the moist sector reaching southern Arkansas by early evening. In response, a pocket of instability is forecast to develop across southeast Oklahoma, southwest Arkansas and northeast Texas, where convective initiation is expected during the mid evening. Thunderstorms are likely to rapidly increase in coverage during the late evening. Most hi-resolution models develop a line of strong to severe storms and move the line slowly eastward across southwest Arkansas and far northeast Texas during the early overnight period. As lift and shear increase due to the approach the mid-level jet, conditions are expected to become favorable for severe storms. Model forecast soundings across the Ark-La-Tex by 06Z have surface dewpoints near 60 F as far north as the Louisiana and Arkansas state line. Even so, MLCAPE should reach the 500 to 1000 J/kg range at the northern edge of the moist sector by late evening. Very strong lift associated with the exit region of the mid-level jet combined with low LCL heights and strong low-level shear should be favorable for supercells embedded in the line, and with the more discrete cells that develop ahead of the line. Some forecast soundings suggest that 700-500 mb lapse rates will approach 8 C/km across the northern part of the warm sector. Although the large-hail threat should remain isolated, the steep mid-level lapse rates should be sufficient for a significant-hail threat. Hailstones of greater than 2 inches in diameter will be possible a few hours after cells initiation, as the storms mature. In addition, 0-3 km storm-relative helicity is forecast to peak near 400 m2/s2 in and just north of the Shreveport vicinity. This is also expected to support a tornado threat with the more intense supercells. Any supercell that can persist and become dominant may be able to produce a significant tornado or two. A wind-damage threat will also likely develop along the line of storms, with the greatest potential located across Ark-La-Tex, where an Enhanced risk has been introduced. ...East Texas/Louisiana... Further south into east Texas and Louisiana, storm coverage is expected to be more isolated from the late evening into the overnight period. In this area, to the south of the mid-level jet axis, instability is not expected to be as strong. Also, lift may not be quite as concentrated. For this reason, supercell development is expected to remain more isolated. Any cell that can become organized and sustained could produce isolated large hail, wind damage and a tornado or two. The severe threat should more isolated with southward extent, with only a marginal severe threat expected near in the coastal sections of southeast Texas and southern Louisiana. ..Broyles/Lyons.. 01/11/2024 CLICK TO GET WUUS01 PTSDY1 PRODUCT NOTE: THE NEXT DAY 1 OUTLOOK IS SCHEDULED BY 1300Z CURRENT UTC TIME: 1111Z (5:11AM), RELOAD THIS PAGE TO UPDATE THE TIME

  16. Huge expansion of the ENH with the latest update
  17. Oh and here is my album from today's storm chase! That storm tried hard (and has been trying still) to put down a tornado. Lots of spin
  18. Gotta say I'm a little confused as to why most of northern Dallas county is under a severe tstorm warning, at least from the radar
  19. Got some shots of the OK mega-cell's tornado-warned southern portion. Will need to upload when home but man was it pretty!
  20. Heading in the direction of Wichita Falls. Depending on how things shake out may end up doubling back to DFW if the "tail end charlie" ends up down here
