SPC Nov 9, 2021 1630 UTC Day 1 Convective Outlook

SPC 1630Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1024 AM CST Tue Nov 09 2021 Valid 091630Z - 101200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS WESTERN WASHINGTON/FAR NORTHWEST OREGON... ...SUMMARY... A brief tornado or locally damaging wind gust is possible this afternoon, mainly across a portion of western Washington. ...Western Washington/northwest Oregon... A shortwave trough and related cold front will continue to move eastward/inland through the afternoon. Via cloud breaks and a trough-associated pocket of -30C 500 mb temperatures, low/mid-level lapse rates will steadily steepen this afternoon, with a few hundred J/kg SBCAPE expected to be maximized along the Washington Coast. This may be sufficient for some semi-stout/sustained low-topped thunderstorms, with strong deep-layer southwesterly winds potentially supportive of organized clusters and possibly a weak/transient supercell or two. A brief tornado and/or convectively enhanced damaging wind gust will be possible, particularly in near-coastal Washington areas this afternoon. ..Guyer.. 11/09/2021 Read more LIVE:
