WW 94 TORNADO TX 091440Z - 092200Z
URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 94 NWS Storm Prediction Center Norman OK 940 AM CDT Tue Apr 9 2024 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Central Texas * Effective this Tuesday morning and afternoon from 940 AM until 500 PM CDT. * Primary threats include... A few tornadoes possible Scattered large hail and isolated very large hail events to 2.5 inches in diameter likely Scattered damaging wind gusts to 70 mph possible SUMMARY...Several thunderstorm clusters, including a mix of supercells and bowing line segments, are expected along a stalled front across central Texas through the afternoon. More isolated supercell development will be possible later this morning into early this afternoon into the I-35 corridor closer to Austin. The storm environment will support the potential for large hail up to 2.5 inches in diameter, damaging gusts of 60-70 mph, and potentially a few tornadoes. The tornado watch area is approximately along and 40 statute miles north and south of a line from 50 miles west of Austin TX to 140 miles east northeast of Temple TX. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU4). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Tornado Watch means conditions are favorable for tornadoes and severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. && AVIATION...Tornadoes and a few severe thunderstorms with hail surface and aloft to 2.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 550. Mean storm motion vector 25025. ...Thompson Read more

SPC 2000Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0258 PM CDT Tue Apr 09 2024 Valid 092000Z - 101200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS OVER MUCH OF CENTRAL AND EASTERN TEXAS INTO LOUISIANA... ...SUMMARY... Scattered severe thunderstorms are likely through tonight across much of Texas into the lower Mississippi River Valley. A few tornadoes and an isolated strong tornado or two, large to very large hail up to 2.5 inches in diameter, and severe gusts of 60-75 mph will be possible. ...TX into LA... A very moist and unstable air mass exists south of an east-west oriented front across central TX. An MCS will likely produce severe weather as it moves from northeast TX into northern LA, along the instability gradient and where shear remains favorable. Farther south, continued heating as well as convergence near the boundary will likely lead to additional development this afternoon, with large hail and expected. Overnight, as cooling aloft with the shortwave trough spreads across central TX, an associated cold front is expected to support additional storms which would travel quickly northeastward across the unstable air mass. Such an overnight scenario would likely yield damaging winds as well as hail. ..Jewell.. 04/09/2024 .PREV DISCUSSION... /ISSUED 1130 AM CDT Tue Apr 09 2024/ ...TX/LA through tonight... A midlevel low over northern Mexico will move eastward toward west TX later today into tonight, with exit regions of embedded jet streaks persisting over central/east TX through tonight. Only weak surface cyclogenesis is expected across central/east TX along a stalled front through tonight, while widespread ongoing convection will persist through the period from central TX eastward into LA. Regional 12z soundings revealed a broad area with rich low-level moisture (boundary-layer dewpoints in the low 70s) beneath a elevated mixed layer with midlevel lapse rates greater than 8 C/km. As a result, MLCAPE of 2000-3500 J/kg will continue along and south of the rain-reinforced front through tonight from central into east TX, with slightly lower buoyancy farther to the east in LA. Low-level mass response will not be particularly large given only weak cyclogenesis in TX, though there could be some increase in low-level shear later this evening into tonight from east TX into LA. Widespread convection and resultant messy convective modes will be the main concern through the period. Observed and forecast hodographs will favor embedded supercells capable of producing a few tornadoes, isolated very large hail up to 2.5 inches in diameter, and damaging gusts of 60-75 mph. Longer/straighter hodographs and closer proximity to the steep lapse rate plume suggest that the hail threat will be greatest across central TX with the more isolated/cellular storm mode. The wind threat will be greater this evening into tonight from east TX into LA, based largely on upscale growth of storms into bowing segments along the stalled front. There will also be some potential for additional storm development tonight across south central TX along the west edge of the richer low-level moisture and with the ejecting midlevel trough, with a conditional threat for very large hail and damaging winds. ...Northern OH area this afternoon/evening... The glancing influence of a midlevel trough moving over Lower MI and a surface cold front could focus isolated thunderstorm development this afternoon/evening across northern OH. Surface heating, a modest increase in low-level moisture and wind profiles with mainly straight hodographs will support some potential for isolated large hail/wind damage for a few hours later this afternoon/evening.
