weatherwiz Posted December 16, 2019 Share Posted December 16, 2019 There is a purpose to this thread...want to start collecting information, thoughts, and ideas for bigger events which can be a tool for research purposes down the road. An extremely unseasonably conducive environment for severe weather (including tornadoes and strong tornadoes) exists across the Gulf coast states. A somewhat uncommon winter-time elevated-mixed layer has advected into the region from the Mexican plateau and is characterized by mlvl lapse rates on order of ~7.5 C/KM. Below the EML exists an extremely moist airmass with sfc dews in the 60's and 70's. This is contributing to MLCAPE values on order of 1500 J/KG with 3km CAPE values greater than 125 J/KG. Couple with with 50+ knots of vertical shear and effective helicity > 300 m2s2 and this is the result... A large and destructive tornado is currently on the ground over Leander, LA. This has been a long-tracked tornado and given the environment may be on the ground for quite a while. Link to comment Share on other sites More sharing options...
