"Stop" is probably the wrong word...but rather it could moderate enough above freezing by the time it reaches kevin. If the euro was showing that 18z solution tomorrow night, I'd forecast ZR for him though. Models are probably going to be too warm at the sfc...the question though is whether we trend warmer for a couple runs before go time. If we got a solution a few degrees warmer by tomorrow night, then the ice maybe only makes it to ORH. Expand Wouldn’t it have to be at least a couple of degrees colder due to latent heat release. That near 32 is very shallow too. Euro is almost as warm as GFS now. Link to comment Share on other sites More sharing options...

If they were to take 95 to 128, would that allow them to miss the ice threat or is that still a bad time to be on the road? Expand Major roads like those I hope are going to be well treated.

Expand No. Latent heat release is an issue in a lot of events because we don't have advection of fresh lower dews...that is definitely not an issue in this event. There is a steady feed of low dewpoint Arctic air from the northeast. That's why some areas could actually get several hours of 34-35F rain and actually fall below freezing during the event and change to ZR. This isn't an antecedent airmass trying to hold on...it's actually bullying it's way in from the northeast. Link to comment Share on other sites More sharing options...

I have no idea how accurate these are but here is the Weatherbell freezing rain product. 1" of ice would definately cause huge problems Expand Correct me if I'm wrong......accumulation is not accretion. This is the total rainfall that would occur with surface temps below freezing. It is not the amount one is going to find on trees and wires.

Expand This is also why the hilltops look to get a lot more ice than the valleys and lowlands. The cold drains in at low levels, but off the deck. So 1500ft could drop to, say 27F, while down at 400ft is at a marginal 32F and not really accreting (meanwhile 5000ft could be 40F).

Ginx snewx Posted December 29, 2019 Share Posted December 29, 2019 Veterans know that Kevin has called for at least 75 damaging ice storms over the years at his house. Actual number 0.

Expand Yeah active drain scenarios almost always favor the elevations which is why it seems the higher end threats seem to have an elevation component. Basically anytime we have a stubborn high in Quebec. The in-situ (esp on SE flow) is where the valleys seem hang on the longest. Link to comment Share on other sites More sharing options...
