Yeah, I was mentioning this earlier (I think yesterday) about the QPF aspect. I’d normally want to see at least 2” of qpf for major ice storm concerns unless it’s like 1.25-1.50 protracted out over like 36-48 hours from mostly light intensity stuff.

It’s rare we get 3 state regions to get near over an inch of qpf as zr . Very rare Link to comment Share on other sites More sharing options...

I mean I guess it could always bump up but a quick thump probably doesn't get it done. Also the NWS is now forecasting straight "flat ice" accretion. No more radial. So 0.5" of flat ice accretion is the new warning threshold but you won't start seeing major impacts until at least 0.75" and probably more like 1.0" Radial ice = flat ice * 0.4 1 Link to comment Share on other sites More sharing options...

It’s still a pretty good icing event, but the old ice storm warning was like “whoa, this is pretty serious”. 1 Link to comment Share on other sites More sharing options...

It’s still a pretty good icing event, but the old ice storm warning was like “whoa, this is pretty serious”. For sure. We've had a couple decent events in CT over the last few years where we've been able to fine tune the impacts with certain flat ice amounts thanks to the ASOS I group. Once you get to 0.5" you start seeing some limbs snap and outages and over 0.75" it starts to get more significant. Link to comment Share on other sites More sharing options...

Even if it turns to freezing rain it’s going to be coming down too hard to cause extensive tree and powerline damage. This isn’t 48 hours of freezing drizzle, It’s a fast moving system. Yeah hopefully a little bit of snow and then mostly sleet here at beast. Freezing rain doesn’t scare me though The masses will just rip up the rain Crust 1 Link to comment Share on other sites More sharing options...

Yeah and that matches with my old radial anecdotes....I always noticed around a quarter inch radial is when you’d start seeing the scattered power outages and then at around 1/3 or 3/8ths is when it would start to seem to “ramp up”.

We usually do reviews for larger winter events and I had to remind the group about not just going back and counting the 6hr I group. Link to comment Share on other sites More sharing options...
ice1972 Posted February 14, 2021 Share Posted February 14, 2021 I’m sorry radial vs flat ice? Is that like accretion on a tree limb vs accretion on a sidewalk or something? 2 Link to comment Share on other sites More sharing options...

I'm gathering from what I've been reading that the max strip might be about .5" accretion. So perhaps some issues, nothing epic. It'll be pretty in any case. 2 Link to comment Share on other sites More sharing options...

We see WSW up 24+ hours before events. For most, this will likely be an advisory event so putting those up later today should be ample notice. 1 Link to comment Share on other sites More sharing options...
mahk_webstah Posted February 14, 2021 Share Posted February 14, 2021 Am I understanding that the trend so far at 12Z is colder surface and maybe aloft on the Nam, and warmer surface and maybe aloft on the GFS. Is the other guidance picking a camp yet? Link to comment Share on other sites More sharing options...
CoastalWx Posted February 14, 2021 Share Posted February 14, 2021 Reggie pretty warm. Brings low right over my head. 1 Link to comment Share on other sites More sharing options...
HIPPYVALLEY Posted February 14, 2021 Share Posted February 14, 2021 Temperatures don’t really get above freezing the rest of the week so any ice may stick around until next system moves in late week. Sun angle should help with branches and power lines though. Link to comment Share on other sites More sharing options...

The pack will certainly be solidified in any event and then we see about Thursday-Friday. 12k looked like about 50/50 snow and sleet for CON...3km maybe a little more sleet. You being a little more north helps. Hopefully we stay mostly snow. I hate clearing tons of sleet. 2 Link to comment Share on other sites More sharing options...
