SPC 1630Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1026 AM CST Sun Nov 07 2021 Valid 071630Z - 081200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected across the contiguous U.S. today. ...Pacific Northwest... Isolated low-topped thunderstorms will remain a possibility today along coastal portions of Washington and Oregon. This scenario is supported by modest moisture and steep mid-level lapse rates coincident with low-amplitude cyclonic upper flow. Buoyancy will be quite limited overall, but somewhat more stout updrafts, including the possibility of small hail, may occur through early/mid-afternoon along the Washington coast. Thunderstorm potential is likely to diminish into this evening/overnight as upper heights begin to build and mid-level temperatures warm. ..Guyer/Squitieri.. 11/07/2021 Read more LIVE: spc.noaa.gov
