George BM Posted April 30, 2021 Author Share Posted April 30, 2021 6 minutes ago, high risk said: One thing to watch is a secondary cold front that will move through in the very late afternoon. NAM Nest is most aggressive is actually generating a line of very gusty showers on the front. The frontal passage itself will likely enhance the winds even further. Just the person I was looking for. Yeah I've been looking at that as well. I'd think it could be interesting with >9C/km 0-3km lapse rates and a bit of inverted-v signatures showing up in soundings should a line or line segments form along the front. 1 Link to comment Share on other sites More sharing options...

When we get effective sunshine during these high wind events it makes the process of mixing down the winds aloft very efficient. Going to be interesting to see what later this afternoon looks like.

PrinceFrederickWx Posted April 30, 2021 Share Posted April 30, 2021 We do wind really well in this region (along with heatwaves and heavy rains). We certainly don’t do anything else good though. 1 Link to comment Share on other sites More sharing options...

WEATHER53 Posted April 30, 2021 Share Posted April 30, 2021 Peak gust 52 and I think winds will increase a bit from 7-10pm. Stay out of the woods warning in my forecast this evening and after feeling like 95 in the direct sun a few days ago by 10pm tonight it will feel like 35-40.

Kmlwx Posted April 30, 2021 Share Posted April 30, 2021 Velocity scans look pretty impressive on that radar activity coming over the mountains now. We will start to battle less mixing from the sun going down - but my guess is there's a good surge of wind damage with that precip. Link to comment Share on other sites More sharing options...
