MD 2287 CONCERNING TORNADO WATCH 715... FOR LOUISIANA
Mesoscale Discussion 2287 NWS Storm Prediction Center Norman OK 0457 PM CST Thu Dec 26 2024 Areas affected...Louisiana Concerning...Tornado Watch 715... Valid 262257Z - 270000Z The severe weather threat for Tornado Watch 715 continues. SUMMARY...Severe threat is expected to spread into central and southern Louisiana this evening. New tornado watch appears warranted. DISCUSSION...Strong, negative-tilt short-wave trough is ejecting across east TX early this evening. 500mb speed max is forecast to translate across northern LA which will encourage LLJ to shift north across the lower MS over the next 3-6hr. As this occurs, warm sector will recover a bit across LA, especially southwestern LA where surface dew points are rising through the mid 60s. This will contribute to near-surface based buoyancy, that appears adequate, for maintaining ongoing, upstream supercell activity. Latest radar data depicts several longer-lived supercells over southeast TX that will track northeast into a strongly sheared air mass, just east of ww715. This evolving risk likely warrants a new tornado watch immediately downstream. ..Darrow.. 12/26/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...JAN...LCH...SHV...

MD 2286 CONCERNING TORNADO WATCH 715... FOR SOUTHEAST TEXAS
Mesoscale Discussion 2286 NWS Storm Prediction Center Norman OK 0326 PM CST Thu Dec 26 2024 Areas affected...Southeast Texas Concerning...Tornado Watch 715... Valid 262126Z - 262330Z The severe weather threat for Tornado Watch 715 continues. SUMMARY...The severe threat continues across southeast TX as a broken line of storms approaches the upper TX Gulf coast and the lower Sabine River. DISCUSSION...Thunderstorms within a broken convective line continue to undulate in intensity with periodic, somewhat well-organized, low-level mesocyclones across the TX Coastal Plain. Despite relatively transient periods of storm organization/intensity, a recent tornado report from the El Campo, TX area indicates that the current convective environment is sufficient for at least brief tornadoes. The KHGX VWP continues to show slowly strengthening low-level winds with 0-1 km SRH oscillating between 150-250 m2/s2, and this trend is expected to continue through early evening as the surface low to the north continues to deepen. Organized precipitation distribution evident in shallow convection in/around the Houston metro area confirms a favorable low-level wind environment is in place, and is contributing to STP values between 2-3. As such, the tornado threat is expected to persist well into the late afternoon/early evening hours as storms push east towards the coast and the lower Sabine River. Recent high-res guidance suggests the tornado threat may peak during the 22-02 UTC period to the east/northeast of the Houston metro towards the Sabine River when the temporal overlap of buoyancy and strong low-level shear will be greatest. Watch issuance east of the river may be needed later this afternoon/evening based on convective trends over the next few hours. ..Moore.. 12/26/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 2284 CONCERNING SEVERE THUNDERSTORM WATCH 714... FOR NORTHEAST TEXAS INTO THE ARKLATEX VICINITY
Mesoscale Discussion 2284 NWS Storm Prediction Center Norman OK 0112 PM CST Thu Dec 26 2024 Areas affected...northeast Texas into the ArkLaTex vicinity Concerning...Severe Thunderstorm Watch 714... Valid 261912Z - 262115Z The severe weather threat for Severe Thunderstorm Watch 714 continues. SUMMARY...The risk for severe wind and hail continues across northeast Texas and the ArkLaTex vicinity. Potential may increase by 21-00z/3-6 pm CST. DISCUSSION...Strong thunderstorms will continue to track northeast across the region through late afternoon. While strong vertical shear is resulting in some organized line segments and more semi-discrete cells, convection has struggled to maintain intensity given the weak thermodynamic environment. Nevertheless, some additional destabilization may occur over the next couple of hours while the low-level jet increases with eastward extent. Isolated large hail to 1.75 inch diameter and gusts to 65 mph still remains possible with elevated convection into early evening. ..Leitman/Thompson.. 12/26/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 2285 CONCERNING TORNADO WATCH 715... FOR SOUTHEASTERN TEXAS
Mesoscale Discussion 2285 NWS Storm Prediction Center Norman OK 0114 PM CST Thu Dec 26 2024 Areas affected...Southeastern Texas Concerning...Tornado Watch 715... Valid 261914Z - 262115Z The severe weather threat for Tornado Watch 715 continues. SUMMARY...The severe threat continues across much of southeast Texas as storms intensify across the region. DISCUSSION...Storm intensification across southeast TX has been gradual over the past several hours with most storms struggling to maintain intensity, possibly owing to numerous destructive storm interactions/colliding outflows. Despite this, the overall trend has been towards more intense updrafts as evidence by colder cloud-top temperatures in GOES IR imagery with the stronger pulses. Additionally, KHGX velocity data has shown a few weak, but persistent, low/mid-level mesocyclones with some of the stronger storms. Environmentally, temperatures continue to warm into the upper 60s to mid 70s ahead of a broken line of storms (delineating the primary surface trough) along the TX coast, and KHGX VWP observations have sampled strengthening winds through the 1-3 km layer over the past 2 hours with 0-1 km SRH between 150-200 m2/s2. Further east into far southeast TX, cooler temperatures are yielding less buoyancy compared to areas further southwest along the coast, but southeasterly winds are supporting effective SRH on the order of 200-250 m2/s2 based on latest RAP mesoanalysis estimates. Latest high-res guidance suggests that the environment will continue to become more favorable for well-organized convection as the surface low deepens to the north, and given the aforementioned convective trends, further intensification appears probable through late afternoon. In the short term, the greatest severe/tornado risk will likely be associated with the stronger cells within the line approaching the Houston area and in far southeast TX where low-level mesocyclones associated with persistent supercells have been noted. ..Moore.. 12/26/2024 ...Please see www.spc.noaa.gov for graphic product...
