MD 0019 CONCERNING TORNADO WATCH 1... FOR SOUTHEAST TEXAS...SOUTHWEST LOUISIANA Mesoscale Discussion 0019 NWS Storm Prediction Center Norman OK 0305 PM CST Mon Jan 08 2024 Areas affected...Southeast Texas...Southwest Louisiana Concerning...Tornado Watch 1... Valid 082105Z - 082200Z The severe weather threat for Tornado Watch 1 continues. SUMMARY...Strong to severe storms have developed along the warm front over southeast TX. DISCUSSION...Latest surface analysis shows the surface warm front now extends roughly from Trinity/Polk counties of southeast TX into Beauregard and Jefferson Davis Parishes of southwest LA. Multiple small supercells storms have formed in vicinity of the front to the east of CLL, where there have been a few recent tornado reports. It is unclear how much farther northeast these storms can remain surface-based, as they cross the warm front into a more stable low-level environment. Other similar storms may form across WW #1 through the early evening, given the very strong low-level shear profiles and favorable thermodynamics. To the southwest, strong storms have formed along the approaching cold front. This activity will move into the HOU metro area in the next hour or two, with some tornado risk. However, linear forcing mechanisms suggest hail/wind might be the primary threat. ..Hart.. 01/08/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 0018 CONCERNING BLIZZARD FOR WESTERN KANSAS INTO SOUTHERN NEBRASKA Mesoscale Discussion 0018 NWS Storm Prediction Center Norman OK 0248 PM CST Mon Jan 08 2024 Areas affected...Western Kansas into southern Nebraska Concerning...Blizzard Valid 082048Z - 090045Z SUMMARY...Blizzard conditions continue into the evening. DISCUSSION...Winds continue to strengthen across western Kansas with sustained winds as high as 44 knots at KULS with numerous locations reporting blizzard conditions. Winds may still strengthen further over the next few hours as the northerly low-level jet continues to strengthen/broaden on the western periphery of the 850mb low. Strong cold air advection also continues with temperatures in the low 20s now across northwest Kansas. Moderate to heavy snowfall within the deformation band will slowly drift east through the evening as the surface low advances eastward. Blizzard conditions will continue across western Kansas and into southern Nebraska through this period with only slow improvement from west to east. ..Bentley.. 01/08/2024 ...Please see www.spc.noaa.gov for graphic product...

SPC 2000Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0159 PM CST Mon Jan 08 2024 Valid 082000Z - 091200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS FROM PARTS OF SOUTHEAST TEXAS INTO SOUTHERN LOUISIANA/MISSISSIPPI/ALABAMA...AND THE WESTERN FLORIDA PANHANDLE... ...SUMMARY... Severe thunderstorms capable of strong/damaging wind gusts and tornadoes are expected across the Gulf Coast States this afternoon through early Tuesday morning, spanning from southeast Texas and southern Louisiana across southern Mississippi, southern Alabama to the western Florida Panhandle. Strong tornadoes are possible. ...20Z Update... The primary changes to the outlook were to trim probabilities from the northwest to reflect the cold frontal passage, and expand probabilities southward along the cold front into central TX, where recent storm development has been noted within a favorable environment. Otherwise, the previous outlook reasoning remains valid. Parts of southeast TX are being monitored for supercell maturation, with potential for all severe hazards. See MCD 17 and Tornado Watch 1 for more information regarding the short-term threats in this area. An extensive QLCS is still expected to develop this evening and move eastward along the Gulf Coast, with recent HRRR runs suggesting some potential for prefrontal supercell development. Any mature pre-frontal supercells could pose a strong tornado threat late tonight across parts of the central Gulf Coast, with damaging wind and line-embedded tornadoes also possible with the primary QLCS. A Moderate Risk upgrade remains possible with the 01Z update, depending on observational and short-term guidance trends regarding northward advance of the warm front and potential for mature prefrontal supercells overnight. ..Dean.. 01/08/2024 .PREV DISCUSSION... /ISSUED 1028 AM CST Mon Jan 08 2024/ ...Synopsis... A powerful upper cyclone over the southern Plains this morning will eject east-northeastward today, eventually reaching the lower/mid MS Valley by early Tuesday morning. A very strong mid-level jet (around 90-110 kt) associated with this cyclone will translate eastward across TX and the lower MS Valley through tonight. Primary surface low over the TX Panhandle this morning is expected to develop across OK today, and it should reach the mid MS Valley by the end of the period. A secondary surface low should develop across coastal/southeast TX today, and into LA and central MS by late this evening. Low-level mass response and warm/moist advection is already occurring in earnest across coastal TX. This trend is forecast to continue as a surface warm front lifts northward across coastal portions of LA/MS/AL and the FL Panhandle this evening through tonight. A cold front attendant to the secondary surface low will continue to sweep quickly eastward across TX and the lower MS Valley through the period. ...North/Central Texas into ArkLaTex today... A line of elevated convection is ongoing this morning across parts of north/central TX along the cold front. This activity should tend to remain elevated in the short term, but some threat for occasional strong/gusty winds may exist this afternoon and evening as the line moves into a gradually destabilizing airmass. Additional convection that forms ahead of the front in a strong low-level warm advection regime could acquire supercell characteristics given the very strong deep-layer shear. These thunderstorms will probably pose some threat for hail even if they remain elevated as they race east-northeastward. ...Southeast Texas into Southwest Louisiana this afternoon and evening... Mid to upper 60s F surface dewpoints will become increasingly common across southeast Texas/southwest Louisiana as a southerly low-level jet strengthens to 50-65 kt across this area. Persistent cloud cover and ongoing showers/thunderstorms along/north of the warm front should limit solar heating to some extent. But, lingering MLCIN should weaken through the afternoon as deep-layer ascent increases and gradual warming of the boundary layer occurs. In tandem with steeping mid-level lapse rates, 1500-2500 J/kg of MLCAPE appears likely to develop by peak heating later this afternoon. Scattered thunderstorms should gradually evolve/deepen as forcing for ascent increases with the ejecting upper cyclone, coincident with strong low-level and deep-layer shear that will easily supercells and an increasing hail, damaging wind, and tornado risk. A few semi-discrete storms/supercells may develop ahead of more linearly organized storms evolving near the cold front during the afternoon and evening. Given the strength of the low-level flow and ample forecast effective SRH, strong tornadoes appear possible. ...Southeast Louisiana into Southern Mississippi/Alabama and the Florida Panhandle this evening through late tonight... Have held at Enhanced Risk with this update due to uncertainty regarding potential for pre-frontal supercells ahead of the squall line, mainly after 06Z tonight. Latest guidance continues to suggest that rich low-level moisture will attempt to rapidly advect northward in tandem with a marine warm front this evening and tonight as a very strong (60-70+ kt) southerly low-level jet develops over the lower MS Valley and Southeast. Elevated showers and thunderstorms occurring in this low-level warm advection regime may tend to hamper the inland extent of the surface warm sector to areas along/near the coast. Even so, both low-level and deep-layer shear appear very favorable for organized severe convection, including the potential for tornadoes and significant damaging winds. Multiple rounds of severe weather will likely occur from parts of southeast LA into southern MS/AL and the FL Panhandle beginning later this evening, and continuing through tonight into early Tuesday morning. The potential for surface-based supercells ahead of the cold front is still somewhat uncertain. But, if any can form and be sustained in the low-level warm advection regime along/south of the warm front, they would be capable of producing strong tornadoes given effective SRH potentially exceeding 400 m2/s2. Greater potential for scattered to numerous damaging winds, some of which could be significant, is apparent with an intense squall line that will likely consolidate and strengthen as it races eastward across southern LA/MS/AL and parts of the FL Panhandle late tonight. Multiple embedded QLCS tornadoes, some of which could be strong given the very favorable low-level shear, are also a distinct possibility. Observational and guidance trends will be closely monitored across this area for signs of increasing pre-frontal supercell potential, which may necessitate greater tornado probabilities in a later outlook.
