SPC 1200Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1217 AM CDT Sun Mar 27 2022 Valid 271200Z - 281200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... A few thunderstorms are possible across the Cascade Range. ...Cascade Range... Latest model guidance suggests a strong mid-level jet will approach the central CA Coast Sunday night with the associated trough not expected to advance inland until later in the day2 period. High-level difluent flow aloft will be noted across the Cascade Range and weak buoyancy is forecast to develop primarily during the latter half of the period. Forecast soundings across the higher terrain suggest ample instability will develop for scattered convection across the Cascades, especially across Oregon. NAM forecast sounding southeast of SLE at 28/03z actually exhibits around 500 J/kg SBCAPE with strong vertical shear supporting organized updrafts. However, weak low-level flow and instability will preclude any severe risk with this activity. Primary risk for lightning will be after 00z. ..Darrow/Bentley.. 03/27/2022 Read more CHECK UPDATE ZOOM GRAPHIC
