SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0742 PM CDT Tue Oct 27 2020 Valid 280100Z - 281200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected across the contiguous United States through tonight. ...01z Update... Another spoke of large-scale forcing for ascent is spreading east into the TX south Plains this evening. Lightning has increased in coverage with weak convection along the leading edge of this forcing near the NM/TX border. 00z sounding from MAF exhibits roughly 200 J/kg MUCAPE if lifting a parcel between 700-750mb. This band of convection should spread northeast into western OK tonight where the boundary-layer temperatures remain below freezing. Significant icing appears to be the primary threat with this activity. Scattered thunderstorms that developed across the central/eastern Gulf Coast region are slowly weakening as they advance inland. Some threat remains across this region tonight due to gradually increasing moisture/weak buoyancy ahead of TC Zeta. ..Darrow.. 10/28/2020
