SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1105 AM CST Mon Nov 29 2021 Valid 301200Z - 011200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... The risk of thunderstorms appears negligible across the U.S. Tuesday through Tuesday night. ...Synopsis... A broad swath of northwesterly mid/upper level flow will stretch from the Pacific Northwest through the eastern U.S. A series of midlevel shortwave troughs will pivot northeast across New England and the Canadian Maritimes while another embedded shortwave trough tracks from the northern/central Plains to the Midwest by Wednesday morning. Surface high pressure will persist over the Southeast, though southeasterly low-level flow will allow for at least some shallow moisture return across western portions of the Gulf Coast vicinity. Onshore flow also will allow for increasing boundary-layer moisture across western WA/OR. While some weak destabilization is possible amid modest midlevel lapse rates, relatively warm midlevel temperatures will preclude thunderstorm activity. ..Leitman.. 11/29/2021 Read more LIVE: spc.noaa.gov
