SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0800 PM CDT Sun Oct 25 2020 Valid 260100Z - 261200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Organized severe thunderstorms are not expected through tonight. ...Discussion... Primary areas of thunderstorm development tonight will be the southern Rockies vicinity in association with ascent and steep lapse rates downstream from a shortwave trough, as well as farther east across the southern Plains region. Storms across the southern Plains will likely develop later tonight as a southerly low-level jet strengthens, augmenting isentropic ascent and theta-e advection in vicinity of a southwest-northeast oriented baroclinic zone. Activity will remain elevated above a stable surface layer. While some hail cannot be ruled out with storms over western TX where steep mid level lapse rates and somewhat greater instability will reside, activity is generally expected to remain below the severe threshold. ..Dial.. 10/26/2020
