URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 712 NWS Storm Prediction Center Norman OK 350 PM CST Mon Nov 20 2023 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Southeastern Louisiana Southern and Central Mississippi * Effective this Monday afternoon and evening from 350 PM until 1100 PM CST. * Primary threats include... A few tornadoes likely with a couple intense tornadoes possible Scattered damaging wind gusts to 70 mph likely Isolated large hail events to 1.5 inches in diameter possible SUMMARY...Thunderstorms will move eastward this afternoon and evening while posing a threat for tornadoes, damaging winds, and isolated hail. The threat for strong tornadoes will likely persist with any sustained supercell. The tornado watch area is approximately along and 90 statute miles north and south of a line from 30 miles north northwest of Natchez MS to 45 miles north northeast of Pine Belt MS. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU2). 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 711... AVIATION...Tornadoes and 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.

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0656 PM CST Mon Nov 20 2023 Valid 210100Z - 211200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF THE LOWER MISSISSIPPI VALLEY... ...SUMMARY... Tornadoes, a couple of which may be strong, scattered damaging thunderstorm winds, and isolated large hail remain possible tonight across portions of the lower Mississippi Valley. ...01z Update... Primary change to 20z outlook is to lower severe probabilities along the cool side of the progressive cold front. Upper low centered over southeast KS continues its slow eastward progression toward southern MO. As a result, high-level diffluent flow has strengthened over the Gulf States. This appears partly responsible for a corridor of severe deep convection that currently extends from eastern LA into central MS. Within this corridor, scattered supercells are observed, at least a few of these are potentially tornadic. 00z sounding from JAN exhibited modest MLCAPE (~800 J/kg) with very strong surface-6km shear (70kt), and 0-3km SRH around 350 m2/s2. Some additional air mass recovery is expected immediately downstream of this activity into western AL as primary surface low lifts northeast into the OH Valley. While the primary dynamic forcing will gradually shift north, southern portions of a strong LLJ will shift east overnight which should allow the aforementioned corridor of severe to advance across MS into western AL. ..Darrow.. 11/21/2023 Read more

MD 2278 CONCERNING TORNADO WATCH 712... FOR MUCH OF CENTRAL MISSISSIPPI
Mesoscale Discussion 2278 NWS Storm Prediction Center Norman OK 0603 PM CST Mon Nov 20 2023 Areas affected...much of central Mississippi Concerning...Tornado Watch 712... Valid 210003Z - 210130Z The severe weather threat for Tornado Watch 712 continues. SUMMARY...The risk for tornadoes appears highest over the next couple hours over south-central Mississippi. DISCUSSION...Large clusters of storms including supercells continue to rapidly move east into central MS, with the strongest supercell over southwest MS. This area has the most favorable environment for a strong tornado, with dewpoints rising to near 70 F, and 0-1 SRH > 200 m2/s2. Indeed, surface winds ahead of this particular supercell cluster remain backed with strong gusts, indicating increased pressure falls and potential strengthening with these storms. Gusting winds also indicate the boundary layer is favorably unstable, which will allow supercells to utilize the full low-level shear available. ..Jewell.. 11/21/2023 ...Please see www.spc.noaa.gov for graphic product...

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...Thunderstorms will continue to intensify this afternoon and evening, while posing a threat for large hail, damaging winds, and tornadoes. There is also a threat for strong tornadoes through this evening with any supercells that can be sustained. The tornado watch area is approximately along and 85 statute miles north and south of a line from 40 miles west of Lufkin TX to 40 miles southeast of Monroe LA.

Mesoscale Discussion 2277 NWS Storm Prediction Center Norman OK 0523 PM CST Mon Nov 20 2023 Areas affected...portions of central and eastern Louisiana Concerning...Tornado Watch 711... Valid 202323Z - 210100Z The severe weather threat for Tornado Watch 711 continues. SUMMARY...Ongoing severe storms will continue to pose a risk for a few tornadoes across WW711 this evening. DISCUSSION...Across parts of central LA, a band of convection has shown slow maturation with a couple of supercells becoming established from the broader convection over the last couple of hour. Ongoing within a moist, and unstable environment, conditions look favorable for these storms to maintain intensity this evening. Strong mid and upper-level shear will continue to favor organized storms including supercells and short line segments. While surface winds have veered slightly this afternoon, low-level hodographs remain long and supportive of strong low-level mesocyclones. Low-level shear should increase to the east beneath a southwesterly low-level jet. As storms mature they should remain capable of a few tornadoes and damaging gusts across central and eastern LA this evening. ..Lyons.. 11/20/2023 ...Please see www.spc.noaa.gov for graphic product...
