Felipe F Posted April 10, 2020 at 02:27 PM Author Share Posted April 10, 2020 at 02:27 PM (edited) Para deixar registrado: Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0244 AM CDT Fri Apr 10 2020 Valid 121200Z - 131200Z ...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS FOR CENTRAL/NORTHERN LOUISIANA...SOUTHEAST ARKANSAS...MISSISSIPPI...WESTERN/CENTRAL ALABAMA... ...SUMMARY... An outbreak of severe thunderstorms appears likely Sunday into Sunday night, with the greatest threat expected from Louisiana east-northeastward through much of the Southeast and Tennessee Valley. Strong, long-tracked tornadoes and potentially widespread damaging wind are possible. ...Synopsis... The ejecting shortwave trough initially over the southern High Plains Sunday morning is forecast to move quickly eastward and then northeastward through the period, as it moves around the periphery of a deepening longwave trough over the central CONUS. As this occurs, a surface low will move eastward to the Mississippi Valley by Sunday afternoon, and then rapidly deepen and move northeastward into the lower Great Lakes by Monday morning. Very strong mass response will draw rich low-level moisture northward into portions of the Southeast. ...East Texas into the Southeast... Ingredients for a potential severe thunderstorm outbreak still appear likely to come together Sunday. Moderate to locally strong destabilization in conjunction with an 80-100 kt midlevel jet and 50-60 kt low-level jet will result in a very favorable environment for organized convection. Ongoing storms across east TX Sunday morning will likely spread northeastward with time and become increasingly surface based as they encounter rapidly increasing low-level moisture, with additional development possible further south near the lower MS River valley by late morning. As the downstream airmass heats and destabilizes, long-track supercells may evolve out of the morning convection and track northeastward into portions of MS/AL, with a corresponding risk of strong tornadoes, large hail, and damaging wind gusts. Some upscale growth is possible with time, which would result in a corresponding widespread damaging wind risk, given extremely strong wind fields. Some threat of damaging wind and a few tornadoes will likely reach portions of the Carolinas by 12Z Monday. ...Mid MS Valley into the OH Valley... Destabilization in the vicinity of the primary surface low into the mid MS Valley/OH Valley is more uncertain, given the potential for disruptive convection further south. However, favorable wind profiles and closer proximity to the ejecting shortwave will support some severe thunderstorm threat in this region as well, with a conditional risk of all hazards given sufficient destabilization. ..Dean/Dial.. 04/10/2020 Edited April 10, 2020 at 02:29 PM by Felipe F 3 Link to comment Share on other sites More sharing options...

O tornado foi classificado como F3, mas algumas fontes dizem que pode ter chegado a F4. Por sorte, casas de concreto são mais comuns no México que nos EUA, e mesmo assim houve mais de 10 mortes.

Felipe F Posted April 12, 2020 at 03:28 PM Author Share Posted April 12, 2020 at 03:28 PM Mesoscale Discussion 0350 NWS Storm Prediction Center Norman OK 1024 AM CDT Sun Apr 12 2020 Areas affected...Portions of northeastern LA...northern/central MS...and far southeastern AR Concerning...Severe potential...Tornado Watch likely Valid 121524Z - 121700Z Probability of Watch Issuance...95 percent SUMMARY...The severe threat will markedly increase by this afternoon, with strong tornadoes, numerous damaging winds, and large hail all likely. A tornado watch will be required across northern/central MS and northeastern LA shortly. DISCUSSION...The airmass across northeastern LA into central MS downstream of a QLCS in northern LA is rapidly destabilizing. A warm advection wing of elevated convection has developed across this area as a marine warm front continues to lift northward. Surface dewpoints are expected to quickly increase into the upper 60s to lower 70s along/south of the northward-advancing warm front as a strong low-level mass response occurs over the ArkLaTex region this afternoon. With continued diurnal heating, MLCAPE should increase into the 1500-3000 J/kg range by peak afternoon heating. Very strong shear is forecast to be present from low through mid levels, which will support robust storm organization both with the ongoing QLCS and with any cells that can form farther south/east across the open warm sector. Latest VWP from KDGX (Jackson, MS) shows substantial low-level hodograph curvature, with 0-1 km shear approaching 50 kt, and 0-1 SRH around 500 m2/s2. Strong tornadoes may occur given the strength of the low-level flow, along with numerous damaging winds if the storm mode remains mostly linear. There is still some uncertainty regarding supercell potential across northern/central MS this afternoon. If any storms can form farther south/east of the ongoing QLCS, they will encounter a strongly unstable and sheared environment favorable for all severe hazards. ..Gleason/Grams.. 04/12/2020 1 Link to comment Share on other sites More sharing options...
