WW 18 TORNADO TX 111500Z - 112100Z
URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 18 NWS Storm Prediction Center Norman OK 900 AM CST Sun Feb 11 2024 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Southeast Texas * Effective this Sunday morning and afternoon from 900 AM until 300 PM CST. * Primary threats include... A couple tornadoes possible Scattered large hail and isolated very large hail events to 2.5 inches in diameter possible Scattered damaging wind gusts to 70 mph possible SUMMARY...A few supercells are expected to spread eastward across southeast Texas through early afternoon along a surface cold front. The storm environment will favor isolated very large hail (up to 2.5 inches in diameter), damaging winds to 70 mph, and a couple of tornadoes with these storms. The tornado watch area is approximately along and 35 statute miles north and south of a line from 35 miles south southwest of College Station TX to 110 miles east of Huntsville TX. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU8). 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 16...WW 17... 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 500.

MD 0129 CONCERNING TORNADO WATCH 18... FOR SOUTHEAST TEXAS INTO FAR WEST-CENTRAL LOUISIANA
Mesoscale Discussion 0129 NWS Storm Prediction Center Norman OK 1124 AM CST Sun Feb 11 2024 Areas affected...Southeast Texas into far west-central Louisiana Concerning...Tornado Watch 18... Valid 111724Z - 111900Z The severe weather threat for Tornado Watch 18 continues. SUMMARY...A supercell south of Lufkin will pose a the greatest risk of a tornado as long as it continues to interact favorably with the warm front. Development elsewhere in WW 18 is possible, but uncertain. DISCUSSION...The tornado threat in WW 18 will remain focused ahead of supercell currently south of Lufkin, TX. This storm is roughly parallel with the warm front which would be the region of greatest concern for a tornado. Away from the warm front, low-level shear is less impressive. Additional storm development is possible southwest of the primary supercell as well as within slowly deepening cumulus within the Sabine Valley vicinity. However, this development, or at least the timing of it, is not certain. ..Wendt.. 02/11/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...LCH...SHV...HGX...

MD 0128 CONCERNING SEVERE POTENTIAL...TORNADO WATCH LIKELY FOR PARTS OF CENTRAL/SOUTHERN LOUISIANA INTO SOUTHERN MISSISSIPPI
Mesoscale Discussion 0128 NWS Storm Prediction Center Norman OK 1104 AM CST Sun Feb 11 2024 Areas affected...Parts of central/southern Louisiana into southern Mississippi Concerning...Severe potential...Tornado Watch likely Valid 111704Z - 111900Z Probability of Watch Issuance...95 percent SUMMARY...A threat for tornadoes, possibly strong, and very large hail will develop this afternoon along the warm front in central LA into southern MS. A tornado watch is likely for parts of these areas. DISCUSSION...Upper 60s F dewpoints are present south of the slowly lifting warm front across central LA/southern MS. A cirrus plume associated with the subtropical jet has generally shifted east allowing at least broken surface heating into the low 70s F. With time, additional heating should promote 1000-1500 J/kg MLCAPE by the afternoon. Deep-layer shear is more than adequate for supercells, which are already ongoing in southeast Texas moving roughly parallel to the warm front. Supercell storms that can remain near the boundary will take advantage of enhanced low-level shear/SRH. There are signs of modestly deepening boundary-layer rolls in the vicinity of central LA/southwest MS. This is a potential area for additional storm development later today, which has also been hinted at by recent HRRR runs. Mid-level ascent is currently weak so it may take more time for any potential development to occur. Given the environment, tornadoes, some potentially strong, and very large hail (1.75-2.75 in.) are possible. A tornado watch will likely be needed within the next 2 hours, unless storms develop along the warm front sooner than anticipated. ..Wendt/Thompson.. 02/11/2024 ...Please see www.spc.noaa.gov for graphic product...

WW 17 SEVERE TSTM AR LA TX 111350Z - 111900Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 17 NWS Storm Prediction Center Norman OK 750 AM CST Sun Feb 11 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Far Southern Arkansas Northern Louisiana Far East Texas * Effective this Sunday morning and afternoon from 750 AM until 100 PM CST. * Primary threats include... Scattered large hail and isolated very large hail events to 2 inches in diameter possible Isolated damaging wind gusts to 60 mph possible SUMMARY...Strong to severe thunderstorms may continue east-northeastward this morning into western/northern Louisiana and far southern Arkansas, with the strongest storms capable of large hail and possibly strong wind gusts. The severe thunderstorm watch area is approximately along and 55 statute miles north and south of a line from 25 miles south southwest of Shreveport LA to 65 miles northeast of Natchitoches LA. 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. && OTHER WATCH INFORMATION...CONTINUE...WW 16... 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 25035. ...Guyer Read more

MD 0126 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR PORTIONS OF NORTHEAST LA...FAR SOUTHEAST AR...AND CENTRAL MS
Mesoscale Discussion 0126 NWS Storm Prediction Center Norman OK 1025 AM CST Sun Feb 11 2024 Areas affected...Portions of northeast LA...far southeast AR...and central MS Concerning...Severe potential...Watch possible Valid 111625Z - 111800Z Probability of Watch Issuance...40 percent SUMMARY...The persistence of elevated supercells capable of producing large hail remains uncertain into Mississippi. Downstream watch issuance is possible, but will remain dependent on convective trends. DISCUSSION...An elevated supercell across northern LA produced numerous reports of large hail around 1.5 - 2.5 inches in diameter as it moved across Shreveport LA earlier this morning. This activity has since weakened slightly and become more linear, as it may be outpacing the better mid-level lapse rates plume and greater MUCAPE available across east TX into central LA. Still, ample deep-layer shear of 50-60 kt will support continued updraft organization with any convection that can strengthen and persist along/north of a surface front draped across central LA/MS. So long as these thunderstorms remain clearly elevated, large hail would remain the primary severe risk. Given that MUCAPE is only slowly increasing along/north of the boundary into central MS, it remains unclear whether the threat for large hail will become sufficient enough to justify Severe Thunderstorm Watch issuance with elevated supercells. Greater tornado potential is expected to remain along/south of the front, and will be addressed in a separate Mesoscale Discussion later. ..Gleason/Thompson.. 02/11/2024 ...Please see www.spc.noaa.gov for graphic product...
