MD 1019 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR PORTIONS OF CENTRAL TEXAS
Mesoscale Discussion 1019 NWS Storm Prediction Center Norman OK 0404 PM CDT Tue Jun 13 2023 Areas affected...portions of central Texas Concerning...Severe potential...Watch possible Valid 132104Z - 132230Z Probability of Watch Issuance...40 percent SUMMARY...A conditional severe threat may ultimately materialize across portions of central Texas before sunset, though convective initiation is uncertain. If storms can develop and mature, supercells are likely, with large hail greater than 2 inches in diameter likely. Convective trends are being monitored for the need of a WW. DISCUSSION...Widespread cloud cover has been giving way to relatively greater insolation over the past few hours, resulting in temperatures warming into the 90s F. 7-8 C/km mid-level lapse rates, overspreading surface dewpoints in the lower 70s F, are contributing to extreme instability, with SBCAPE/MLCAPE exceeding 5500/4500 J/kg (per 20Z mesoanalysis). With effective bulk shear values exceeding 65 kts (driven by strong speed shear and resultant elongated hodographs), the ambient environment is highly supportive of intense splitting supercells capable of producing significant severe hail. However, overall forcing for ascent is expected to be modest at best as a weak mid-level perturbation overspreads the region. Furthermore, some capping/cloud cover remains across the warm sector, further reducing the confidence of convective initiation, at least in the short term. A small area of agitated cumulus has developed just west of the moist axis in the Irion/Tom Green County area and these cumulus are being monitored as a possible source of convective initiation. If confidence increases in initiation, a WW issuance may eventually be issued. ..Squitieri/Thompson.. 06/13/2023 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...FWD...EWX...SJT...

SPC 2000Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0300 PM CDT Tue Jun 13 2023 Valid 132000Z - 141200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS NORTH-CENTRAL TX... ...SUMMARY... Severe thunderstorms are still expected this afternoon into tonight from parts of the southern High Plains to the Southeast, with large hail and damaging winds possible. Highest severe thunderstorm coverage is expected over north Texas. ...20Z Update... ...Southern Plains into the Southeast today into tonight... Warm, moist, and strongly unstable air mass remain in place from the southern Plains through the Southeast. Numerous strong to severe thunderstorms are already ongoing, with 4 Severe Thunderstorm Watches (280, 281, and 282) currently in place. The stronger shear is expected to stay over western portions of the region, with mesoanalysis currently estimating effective bulk shear around 60 kt from north/central TX across LA. Recent VAD from FWS sampled 63 kt of effective bulk shear. Robust buoyancy exists over this region as well, and the overall environment appears favorable for splitting supercells. Very large hail will remain the primary severe risk through the evening. Farther east, thunderstorms have trended towards more linear structures across southern AL and southern GA. This trend is expected to continue, with some additional ascent provided by the convectively enhanced vorticity maximum moving through the region. As such, the severe threat is expected to continue across the region and into adjacent parts of the FL Panhandle/northern FL. ...Southern High Plains into Oklahoma this afternoon and evening... Thunderstorms are expected to continue maturing across southeast CO/northwest NM, eventually bringing these storms into the TX/OK Panhandle. Moderate buoyancy and shear will support some strong to severe storms, and Severe Thunderstorm Watch 283 was recently issued to cover this threat. These storms may persist into the evening hours, with some potential to remain strong to severe as far east as central OK by 06Z. These storms should gradually become elevated over time, trending towards mainly a hail risk. ..Mosier.. 06/13/2023 .PREV DISCUSSION... /ISSUED 1135 AM CDT Tue Jun 13 2023/ ...Synopsis... Scattered to widespread thunderstorms are in progress along the immediate cool side of an west-to-east oriented baroclinic zone located across portions of central TX and extending eastward across parts of central MS/AL. These storms persist within a warm-air advection regime driven by a veering and gradually weakening low-level jet overspreading the Mid South. With time, the upper ridge across the southern Plains will subside to a degree, with mid-level westerly flow increasing in magnitude. During the mid to late afternoon hours, a mid-level impulse embedded in the broader westerly flow will eject from the southern Rockies, initiating newer rounds of strong to severe thunderstorms along the southern High Plains, and across central Texas. ...Arklatex into the Southeast today into tonight... Strong to potentially severe storms are ongoing within the warm-air advection regime. Surface temperatures warming into the 80s F amid near 70 F dewpoints will contribute to 3000 J/kg of thin MLCAPE (given mediocre mid-level lapse rates). The stronger mid-level flow overspreading the region will support elongated hodographs, with multicells and short line segments the expected storm modes. Large hail will be possible with the stronger cells and a few damaging gusts may also occur with storms on the warm side of the baroclinic zone, where steeper low-level lapse rates will reside. Later tonight, as the low-level jet increases in intensity, warm-air advection will encourage elevated thunderstorm development atop a stable boundary layer across the Arklatex into the Southeast. Large hail will be the main threat with these storms. ...Central into northeast Texas this afternoon and evening... In the wake of earlier storms, a warm/moist boundary layer is expected to develop through the afternoon. As mid-level flow intensifies over TX, steep mid-level lapse rates will overspread the deepening boundary layer, contributing to strong to extreme instability (i.e. 4000+ J/kg of wide CAPE, especially above 700 mb). Mainly straight but elongated hodographs will support splitting supercell structures later this afternoon. Given the depth of buoyancy above the freezing level and 50+ kts of effective bulk shear/elongated hodographs, very large hail is likely with the more established supercells. Later into the evening/overnight hours, elevated supercell structures should persist as they approach the Arklatex vicinity, with a continued threat for large hail. ...Southern High Plains into Oklahoma this afternoon and evening... Upslope flow and the passage of the aforementioned mid-level impulse will result in convective initiation along the lee of the southern Rockies. The eastward advection of 8-9 C/km lapse rates will support at least moderate instability amid elongated hodographs, supporting supercell structures capable of producing large hail (a couple stones of which may exceed 2 inches in diameter). These storms may persist into the evening hours, with some guidance member suggesting storms may remain strong to severe as far east as central OK by 06Z. By evening, these storms should gradually become elevated, producing large hail and perhaps a severe gust. Read more

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1247 PM CDT Tue Jun 13 2023 Valid 141200Z - 151200Z The previous forecast (see below) remains on track, and only minor adjustments were made with this update. ..Weinman.. 06/13/2023 .PREV DISCUSSION... /ISSUED 0229 AM CDT Tue Jun 13 2023/ ...Synopsis... Mid-level westerly flow on Wednesday will be weaker than it has been the last several days and on Day 1/Tuesday. However, it will remain around 30 to 35 knots which will provide enough momentum atop a deeply mixed boundary layer for some enhanced low-level flow across eastern Arizona, southern New Mexico, and far West Texas. This region will remain very dry with single digit relative humidity. Some dry and breezy conditions are expected across eastern Oregon on Wednesday as a mid-level trough shifts east across the Northwest. However, it is early in the season and fuels remain moist across the region. Therefore, no Elevated area is needed. ...Please see www.spc.noaa.gov/fire for graphic product... Read more

SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1230 PM CDT Tue Jun 13 2023 Valid 141200Z - 151200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS FROM NORTHEAST LA ACROSS CENTRAL MS AND AL AND INTO SOUTHWEST GA... ...SUMMARY... Thunderstorms capable of producing all severe hazards, including very large hail and tornadoes, are possible across much of the Lower Mississippi Valley and Southeast States on Wednesday. ...Synopsis... Upper pattern is forecast to feature a trough/ridge/trough pattern within the northern stream over the northern CONUS and southern Canada. This pattern is expected to remain largely unchanged throughout the period, with only a modest eastward shift anticipated. Anomalously strong mid-level flow will persist throughout the southern stream, with 50 kt at 500-mb stretching from the southern Plains across the Southeast and into the western Atlantic Ocean. A series of convectively augmented shortwave troughs are forecast to progress through this corridor of enhanced westerlies. As such, the evolution of preceding convection will play a large role in determining the strength and location of these shortwaves. Primary surface features influencing the severe potential on Wednesday will be the convectively reinforced boundary extending from west to east from northeast TX across the central portions of the Southeast. Precise location of this boundary is in question, given the likelihood its position will be modulated by thunderstorm activity. The airmass in the vicinity of this boundary will be very moist, with dewpoints likely in the low 70s, and warm, with temperatures south of the boundary reaching the likely reaching the low 90s by the early afternoon. This warm and moist air mass will exist beneath a stout elevated mixed-layer, contributing to strong/extreme buoyancy and the potential for severe thunderstorms. ...Northeast TX into Lower MS Valley and Southeast... A confluence of unusually strong westerlies, steep mid-level lapse rates, and ample low-level moisture/buoyancy will result in severe potential across much of the Lower MS Valley and Southeast on Wednesday. As mentioned in the synopsis, the general expectation is for convectively reinforced boundary to extend from northeast TX across the central portions of the Southeast. Given the overall environmental conditions, severe thunderstorms will be possible on both sides of this boundary. High-resolution guidance offers varying solutions on how thunderstorms evolve across this region, all of which are largely dependent on how each model handles the preceding and/or early period development. Even so, similarities within the guidance allow for some insight towards potential convective evolution. A general east-to-west timing is favored, with the earlier development anticipated over southern AL and GA and the later development anticipated during the early evening from northeast TX into the Mid-South. The early thunderstorms across southern AL and GA will likely trend towards a more clustered/multicellular storm mode, but robust updrafts capable of damaging gust and large hail are still possible. The next round of storms is anticipated from the middle TN/northern MS/northern AL vicinity, likely forced by a convectively augmented shortwave trough moving through. These storms will likely be north of the surface boundary, but environmental conditions will still be very supportive of severe thunderstorms. Given the forcing, a more multicellular/cluster storm mode is expected here as well. Even so, steep mid-level lapse rates could still support the potential for updrafts capable of very large hail. A trend towards more upscale growth/linear organization is possible with these storms overtime, with an attendant threat for damaging gusts as the resulting line moves downstream. Later afternoon/early evening storms are then forecast farther west, from northeast TX into central MS/AL, along the outflow from earlier storms. A more discrete mode is possible here, with supercells capable of all severe hazards, including very large hail and tornadoes, likely. As with other areas farther east, cold pool amalgamation and a trend towards more linear structure is anticipated after a few hours of a more discrete/cellular mode. ...Northern Mid-Atlantic into southern New England... Modest air mass destabilization is expected across the region ahead of an upper low drifting eastward/southeastward. One or more north-south orientated convective lines are expected as ascent attendant to this cyclone moves through. Buoyancy will be modest, mitigated by weak lapse rates, but a few stronger gusts are possible as these lines move northeastward. ..Mosier.. 06/13/2023 Read more

MD 1004 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR SOUTHERN OK INTO NORTH TEXAS
Mesoscale Discussion 1004 NWS Storm Prediction Center Norman OK 0447 PM CDT Mon Jun 12 2023 Areas affected...southern OK into north Texas Concerning...Severe potential...Watch possible Valid 122147Z - 122315Z Probability of Watch Issuance...40 percent SUMMARY...A cluster of storms near the Red River in south-central Oklahoma may pose a strong gust and large risk the next couple of hours. Additional storms may develop southward across north Texas the next few hours, but this remains uncertain. DISCUSSION...A cluster of storms across south-central OK will continue to track east/southeast the next couple of hours. An Oklahoma Mesonet site at Walters measured a gust to 42 mph in the past hour and MRMS MESH indicate hail to 1.5-1.75 inches possible. This activity is elevated behind a front/convective outflow, though MUCAPE around 1000 J/kg. Additionally, modest midlevel lapse rates and elongated hodographs suggest strong storms may continue near the Red River in the short term. To the south, a gradient of strong instability exists across north TX. While this area also remains behind the convectively reinforced outflow to the south across central TX, strong vertical shear is present amid temperatures in the mid/upper 80s and dewpoints in the mid/upper 60s. Additional, elevated storms may develop in this environment, posing mainly a large hail risk. Given the conditional nature of the threat, and uncertainty in timing/coverage of any additional storm development, the need for a watch remains possible but uncertain. ..Leitman/Hart.. 06/12/2023 ...Please see www.spc.noaa.gov for graphic product...
