A couple of strong tornadoes will be possible this evening into tonight across north-central Texas and southeast Oklahoma. Elsewhere, very large hail will be possible late tonight across west Texas as additional thunderstorms develop. .... 01Z Update ... The major change to this update is to introduce an enhanced risk (Level 3 of 5) for tornadoes across north-central Texas into southeast Oklahoma. Here, surface dewpoints into the mid 60sF along, southeast surface winds, and an increasing low-level jet will yield an increasingly favorable environment for a couple of strong tornadoes through the evening and into the overnight hours. The observed 00Z RAOB from Dallas/Fort Worth is indicative of this kind of environment with MLCAPE around 1500 J/kg and 0-3km SRH of 380 m2/s2. Additional thunderstorms capable of producing very large hail and damaging wind threat should redevelop/continue into tonight across portions of west Texas as the main upper-level low begins to eject into the Plains. ...Marsh.. 04/20/2025 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
