SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1200 AM CST Fri Nov 27 2020 Valid 281200Z - 291200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Organized severe thunderstorms appear unlikely across the contiguous United States on Saturday. ...Synopsis and Discussion... A closed upper low initially over the southern High Plains should move slowly eastward across TX/OK on Saturday. A weak surface low is forecast to form over the western Gulf of Mexico ahead of this feature, eventually reaching the coastal LA vicinity by early Sunday morning. Large-scale lift ahead of the upper low and weak low-level warm advection will likely support numerous to widespread showers and thunderstorms across central/east TX Saturday morning, which should limit instability. The majority of this convection is expected to remain elevated, as a surface front should generally move off the middle/upper TX Coast through the day. As the surface low develops northeastward over the western Gulf of Mexico, increasing low-level moisture will begin to approach the LA Coast late Saturday night into early Sunday morning as a marine warm front develops slowly northward. At this point, it appears that the potential for surface-based thunderstorms will probably remain offshore from the LA Coast through the end of the period. Accordingly, severe probabilities have not been included. ..Gleason.. 11/27/2020
