SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1100 AM CST Sun Nov 07 2021 Valid 081200Z - 091200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected across the contiguous United States on Monday. ...Synopsis and Discussion... An upper trough over the eastern Pacific should amplify as it approaches the West Coast Monday night. A 50-60+ kt mid-level jet associated with an embedded shortwave trough is forecast to move over parts of northern/central CA in this time frame. Strong large-scale ascent preceding the mid-level jet/shortwave trough should overspread this region as temperatures aloft gradually cool. Even though low-level moisture will remain modest, various forecast soundings from the latest NAM/RAP show weak elevated instability developing across coastal and inland portions of northern/central CA from Monday night through early Tuesday morning. This meager buoyancy combined with the pronounced large-scale ascent may be sufficient to support charge separation and isolated lighting flashes with the strongest updrafts. Elsewhere, instability is expected to remain minimal to nil across the rest of the CONUS Monday, with little potential for storms. ..Gleason.. 11/07/2021 Read more LIVE: spc.noaa.gov
