Severe thunderstorms are unlikely through tonight. ...Western OR and northern CA... A strong upper trough is approaching the coast of northern CA and southwest OR, with the associated surface cold front moving ashore in the next couple of hours. Strong onshore flow, lift in vicinity of the front, and cold temperatures aloft may result in isolated lightning flashes this afternoon along the coastal ranges and interior mountains of northern CA/western OR. Present indications are that this activity will be quite sparse. ...ID/MT... Later tonight, the aforementioned shortwave trough will track inland and affect portions of ID/MT. Steep mid-level lapse rates and continued strong large scale lift will result in convective showers over the mountains of central ID into western MT. Profiles will be quite cold, but pockets of weak instability may be sufficient for a few lightning flashes - mainly after midnight. ..Hart/Lyons.. 12/06/2023 Read more View the full article Quote Link to comment Share on other sites More sharing options...
