Low topped squall line Friday/strong winds

Yes I got that, but hmm.   I almost think that CAA is weak here.   Maybe a little more pronounced out your way where that d-p is steeper, and where the sounding supports some chop.

No argument at all. Like I said didn't really eyeball your neck of the woods too close since not my AOR. Proximity to the delta-p couplet  will be BIG behind front.

Out your way less than for me + you may not be as deep into the dry slot as areas west will.

this is a good example of when you could/should go with the short-lived high wind warning or develop a new product

Was thinking the same thing this morning. We already have an advisory and warning for wind. The only reason this event doesn't qualify is because it lasts about 10 minutes instead of the requisite three hours or whatever it is now. I just had the line blow through here. Some good gusts, but nothing crazy unless I missed it. Trees still mostly foliated despite the wind gusts.

yeah i think i've seen them use the HWW though for small squall lines like this. i'm *pretty sure* that we had one just a few years ago actually

just double checked...you just need the gust, no time requirement for that

 

It's true, but it gets complicated when you are trying to time the line across the CWA. You end up with a HWW out for a much longer period of time than winds actually last, and the public always interprets it as a bust when trees aren't raining down on their house ahead of or behind that line.

 

You could treat it more short fused, and not issue until it's on your doorstep, but then it's a little more time consuming when you're creating/deleting HWW grids instead of drawing polygons. No real easy way to go about it.

yeah makes sense. i'm almost positive a few years back we had an advisory up and had a similar set-up with a thin convective line embedded and BOX opted to upgrade places to the HWW as the line crossed.

Oh yeah, it's definitely an option as far as regs go. My point was that it's more cumbersome to do it in the grids as opposed to drawing polygons with WarnGen. We might luck out up here, where the line it weak enough and the gradient winds behind the front are what does the damage.
