SPC 1630Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1029 AM CST Sat Dec 28 2024 Valid 281630Z - 291200Z ...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND TONIGHT ACROSS PORTIONS OF EAST TEXAS...LOUISIANA...CENTRAL AND SOUTHERN MISSISSIPPI...AND SOUTHWESTERN ALABAMA.... ...SUMMARY... Tornadoes (some strong with at least EF2 damage possible), severe gusts and hail are expected today into tonight. The threat area will shift eastward from parts of north and central Texas early, across east Texas and the lower Mississippi Valley today, then over the Tennessee Valley, parts of Georgia, and the central Gulf Coast tonight. ...East TX to AL/GA... A powerful mid-level shortwave trough and associated 80-90 knot jet max will rotate quickly eastward across TX today and become negatively-tilted as it tracks into the lower MS Valley this evening. Ample low-level moisture (dewpoints in the mid 60s to lower 70s) is in place ahead of this system across east TX, much of LA, and central/southern MS. Morning convection is slowly weakening across the warm sector, and low-clouds will continue to erode. This will help to develop a corridor of moderate instability with MLCAPE values of 1500-2000 J/kg. This will set the stage for a significant severe weather event through the evening as supercells and bowing structures form over east TX and race eastward across LA into MS. The co-location of the mid-level jet, strengthening winds in the low-levels, surface cyclogenesis, and ample moisture provide a synoptically-evident setup for all severe hazards through the evening. The corridor of greatest concern will be late afternoon through the evening from central LA into central MS. Considered an upgrade to HIGH for this area, but will maintain the ongoing MDT after consultation with local WFOs. Strong and long-tracked tornadoes and widespread damaging winds are possible in this region, with the primary uncertainty regarding storm-mode and linear forcing mechanisms. Activity will spread across AL overnight, where slightly less low-level moisture will somewhat decrease the overall severe threat. Nevertheless, an active squall line with damaging wind potential and embedded rotating storms/tornado threat will likely persist. ..Hart/Lyons.. 12/28/2024 Read more

WW 717 SEVERE TSTM AR OK TX 281125Z - 281800Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 717 NWS Storm Prediction Center Norman OK 525 AM CST Sat Dec 28 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Southwestern Arkansas Extreme southeastern Oklahoma North-central and northeast Texas * Effective this Saturday morning from 525 AM until NOON CST. * Primary threats include... Scattered large hail and isolated very large hail events to 2 inches in diameter possible SUMMARY...Increasing coverage and intensity of elevated thunderstorms, with potential for large hail, are expected through the remainder of the morning, with activity spreading from the DFW Metroplex vicinity into the Arklatex. A separate tornado threat may evolve later this morning in or near the southern/eastern parts of this watch, and would be addressed then and separately. The severe thunderstorm watch area is approximately along and 50 statute miles north and south of a line from 25 miles north northwest of Stephenville TX to 10 miles north northeast of Texarkana AR. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU7). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Severe Thunderstorm Watch means conditions are favorable for 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. Severe thunderstorms can and occasionally do produce tornadoes. && AVIATION...A few severe thunderstorms with hail surface and aloft to 2 inches. Extreme turbulence and surface wind gusts to 50 knots. A few cumulonimbi with maximum tops to 450. Mean storm motion vector 25030. ...Edwards Read more

MD 2297 CONCERNING SEVERE POTENTIAL...WATCH LIKELY FOR PORTIONS OF CENTRAL TEXAS
Mesoscale Discussion 2297 NWS Storm Prediction Center Norman OK 0838 AM CST Sat Dec 28 2024 Areas affected...portions of central Texas Concerning...Severe potential...Watch likely Valid 281438Z - 281615Z Probability of Watch Issuance...80 percent SUMMARY...The severe threat is increasing across central portions of Texas. Severe wind and hail appear to be the predominant threats with the stronger storms that develop, though a tornado or two cannot be ruled out. A WW issuance may be needed in the next couple of hours. DISCUSSION...The boundary layer is expected to gradually warm through the morning (given diurnal heating), where upper 60s F surface dewpoints are in place. 7 C/km mid-level lapse rates and deep-layer ascent are overspreading central TX in tandem with the mid-level trough and associated 70-90 kt upper-level jet streak. As such, thunderstorms are already developing along a Bosque-Kendall County line ahead of the cold front, and they should continue to gradually organize/intensify further throughout the morning. 50+ kt effective bulk shear is already present over the warm sector, and shear (as well as boundary-layer based buoyancy) should only increase with time. Supercells are possible within this developing band of storms, as well as with any storms that can develop and mature ahead of the line, as suggested by high-resolution model guidance. Given relatively steep lapse rates amid curved and elongated hodographs, severe hail and wind are likely with the stronger storms. Low-level hodographs are not particularly large (evident via the GRK VAD). However, given rich low-level moisture and strong deep-layer forcing/shear, a tornado or two cannot be ruled out, especially with any sustained supercell preceding the main line of storms. A WW issuance will likely be needed over the next hour or so. ..Squitieri/Hart.. 12/28/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...HGX...FWD...EWX...
