SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0651 PM CST Thu Dec 26 2024 Valid 270100Z - 271200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE SABINE AND LOWER MISSISSIPPI VALLEYS... ...SUMMARY... Strong to severe thunderstorms, associated with severe wind gusts, hail and a few tornadoes, will move eastward across far southeast Texas, Louisiana and southern Arkansas this evening. ...Southeast Texas/Louisiana/Southern Arkansas... The latest water vapor imagery shows a mid-level trough moving across east-central Texas. At the surface, a low is in northeast Texas with a cold front moving eastward through east and southeast Texas. Scattered strong to severe storms are ongoing ahead of the front from far southeast Texas into far western Louisiana. Ahead of the front, surface dewpoints range from the mid 50s F in southern Arkansas to the upper 60s F in southwest Louisiana. Along the western edge of the moist corridor, the RAP has low-level lapse rates of 5 to 6 C/km, with MLCAPE in the 500 to 1000 J/kg range, except in the Houston/Galveston area where MLCAPE is near 1500 J/kg. In spite of the relatively poor thermodynamic environment, strong deep-layer shear is present across much of the moist sector. The Fort Polk WSR-88D VWP appears to be sampling the strongest deep-layer shear, with 0-6 km shear near 70 knots. The strong deep-layer shear will continue to support supercell development with cells that remain semi-discrete ahead of the front. Supercells and organized multicell line segments will have the potential to produce severe wind gusts and hail. In addition, a narrow 40 to 50 knot low-level jet is analyzed by the RAP from far southeast Texas to northwest Louisiana. Low-level shear, associated with this feature, should be strong enough to maintain a tornado threat for several more hours this evening. The tornado threat will be the greatest with supercells and quasi-linear convective systems. ..Broyles.. 12/27/2024 Read more

WW 715 TORNADO LA TX CW 261735Z - 270100Z
URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 715 NWS Storm Prediction Center Norman OK 1135 AM CST Thu Dec 26 2024 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Extreme west central Louisiana East central and southeast Texas Coastal Waters * Effective this Thursday morning and evening from 1135 AM until 700 PM CST. * Primary threats include... A few tornadoes likely with a couple intense tornadoes possible Scattered large hail and isolated very large hail events to 2 inches in diameter possible Scattered damaging wind gusts to 70 mph possible SUMMARY...Scattered supercell development is expected across southeast Texas through the afternoon/evening, and storms will spread northeastward into east central Texas. The storm environment will support the potential for several tornadoes, including a strong (EF2+) tornado or two, along with large hail of 1-2 inches in diameter and isolated severe outflow gusts of 60-70 mph. The tornado watch area is approximately along and 85 statute miles east and west of a line from 70 miles north of Lufkin TX to 15 miles west of Houston TX. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU5). 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. && OTHER WATCH INFORMATION...CONTINUE...WW 714... AVIATION...Tornadoes and a few severe thunderstorms with hail surface and aloft to 2 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 23035. ...Thompson Read more

Scattered damaging wind gusts to 70 mph possible Scattered large hail events to 1.5 inches in diameter possible A tornado or two possible SUMMARY...Elevated thunderstorms, some with supercell structure, will pose a threat for large hail (1-1.75 inch diameter) and isolated severe wind gusts (60-70 mph) through the afternoon. By late afternoon/evening, an isolated tornado or two could occur near the southern edge of the watch. The severe thunderstorm watch area is approximately along and 75 statute miles east and west of a line from 70 miles north of Longview TX to 20 miles east southeast of Tyler TX. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU4). 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 1.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 450. Mean storm motion vector 22035. ...Thompson Read more
