SPC Nov 15, 2021 0600 UTC Day 1 Convective Outlook

SPC 1200Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1127 PM CST Sun Nov 14 2021 Valid 151200Z - 161200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not forecast across the contiguous United States today. ...Synopsis... A stable pattern will continue today as a large upper trough slowly moves across the Northeast. Meanwhile, an upper ridge will move from the Rockies into the Plains, as another upper trough dives into the Pacific Northwest. Cool temperatures aloft may yield very weak instability over parts of WA, but the bulk of this precipitation will be without lightning. High pressure will remain situated over the Southeast, maintaining dry conditions there. Shallow low-level moisture return will begin over TX late in the day, but little if any appreciable instability will develop. As such, thunderstorms are not expected across the CONUS today. ..Jewell.. 11/15/2021 Read more LIVE:
