MD 0297 CONCERNING TORNADO WATCH 54… FOR PORTIONS OF CENTRAL INTO NORTHERN TEXAS
Mesoscale Discussion 0297 NWS Storm Prediction Center Norman OK 0724 PM CDT Mon Mar 21 2022 Areas affected...portions of central into northern Texas Concerning...Tornado Watch 54... Valid 220024Z - 220200Z The severe weather threat for Tornado Watch 54 continues. SUMMARY...The severe threat continues across Tornado Watch 054. A QLCS tornado and damaging-wind threat is expected across the northern portions of the watch, while supercells with tornadoes (some possibly strong) should continue across central parts of the watch for at least a few more hours. DISCUSSION...A QLCS is maturing across northern Texas per latest MRMS mosaic radar imagery. Meanwhile, at least 4 supercells with a history of producing tornadoes are ongoing across central Texas. Storms within both regimes are impinging on the western fringes of the low-level jet and associated strong low-level shear, which is likely supporting the relatively robust tornado production that has been observed over the past few hours. A moist, buoyant thermodynamic profile is accompanying the low-level jet per 23Z mesoanalysis, with over 2000 J/kg MLCAPE residing ahead of both the supercells and QLCS. Damaging winds and isolated tornado potential should continue with the QLCS through the remainder of the evening, including in areas east of the ongoing watch (please see Mesoscale Discussion #0296 for more details). Farther south, supercells are remaining discrete and are continuing in a favorable CAPE/shear environment for continued tornado production. It is possible that the Pacific front/dryline to the immediate west may catch up to the storms. In this case, the supercells may grow upscale into an MCS similar to what has happened farther north. However, Warn-on-Forecast high-resolution ensemble guidance suggests that supercells may remain discrete through 02Z. The best corridor for tornadic supercells may be from Falls/Lee County and points northeast, as storms farther to the south may be struggling due to weaker flow in the 850-700 mb layer. ..Squitieri.. 03/22/2022 ...Please see www.spc.noaa.gov for graphic product...
