Whineminster Posted February 5, 2019 Share Posted February 5, 2019 Hopefully this is like 1998 but down in my area. Hopefully a tree falls on my house so i can collect insurance and put it towards a kitchen or something. Link to comment Share on other sites More sharing options...

ORH_wxman Posted February 5, 2019 Author Share Posted February 5, 2019 Too bad we don't have 950mb on the Euro...that's def been the coldest layer on the soundings. But seeing -2s there in MA shows that we're prob at least -3C and maybe -4C a bit below that layer before it warms a little bit near the surface back to 30-31F.

dendrite Posted February 5, 2019 Share Posted February 5, 2019 I think if I stay mostly sleet you guys will do really well down there. If my 950 cold can't overcome the layer of +4C aloft and I remain mostly ZR, it may become more of an elevated issue down there...especially once the low level cold advection wanes.

Yeah the sleet will keep the latent heat aloft and not near the surface....so the dewpoint drain will remain relatively fresh,. Link to comment Share on other sites More sharing options...

Damage In Tolland Posted February 5, 2019 Share Posted February 5, 2019 I guess the question is do all of us in the all /mainly ice areas do we pound down .75-1.0” qpf in 32 or below.. or does it take hours to get down under 32. That could make a difference Link to comment Share on other sites More sharing options...

That could make a difference Watch temps tomorrow afternoon...how much do we warm. While wetbulbing will be fairly quick, any lag could make a difference. If the high is like 35-36F and we're already back to 32F by 00z before the precip arrives, then it's gonna be pretty icy very quickly. Link to comment Share on other sites More sharing options...

It would be nice if we had ECMWF soundings....RGEM is cold too and keeps you mostly sleet. RPM actually has you snow for a while and then sleet. I'm guessing the Euro is closer to the RGEM/RPM combo because it has the 546 thickness over Ray's fanny around 06z....while the NAM has it north of you near MWN.

I just tend to give the NAM a little more credence with its mid-level warmth. I’m curious to see which side, if any, caves a little at 00z. Knock that warm layer to +2C to +3C and I’ll have my helmet ready. Link to comment Share on other sites More sharing options...

The warm layer could be accurate and cold layer underdone too...that is what happened in 1/20....they were getting scalped down in BDL and into N RI despite warm layers of like +6to +7. Granted, I don't think the cold layer will be that prolific this time, but you're also not going to be getting +6 or +7 warm layer either. Even the NAM sounding has well over 1000m cold layer that maxes out around -5C. That's prob sleet and that's the warmest model. I think we will need a warmer trend for mostly ZR up there.

Usually I'm one phase change colder than you guys down there. So if you're seeing good ZR chances are I'm pinging. If I'm getting good ZR it's probably 34F -RA or the icing is relegated mostly to ORH and 1kft. I had quite a bit of sleet in 08 before flipping to some solid ZR, but that system was obviously an extreme example. But yeah, it'll probably verify as mostly PL here and ZR down there. I'm just really cheering against it. Link to comment Share on other sites More sharing options...

Did you look at the Euros qpf timing and surface temps, its colder for Kev at max precip It was 31-32 there. The problem is the antecedent airmass is so so. Reminds me of 08 (not saying magnitude will be that). But being further and further remove from the source region could hurt. This is nothing like 2.5 weeks ago. Sure he could get Siggy ice if we really get the dew drain, but ageo flow to me doesn’t look as impressive as past events. Link to comment Share on other sites More sharing options...

ORH_wxman Posted February 5, 2019 Author Share Posted February 5, 2019 18z NAM is weird...lower thicknesses than 12z run but significantly less CAD near the surface...warms ORH above freezing by 09z Thursday morning. Not sure why it does that...I notice on the isobars when toggling the two runs, the CAD looks better on 12z despite higher thicknesses. That solution verbatim wouldn't be that bad for icing...prob nasty for a few hours and then warms above freezing. But the QPF increase is notable. We'll have to keep watching that...models will tend to erode the sfc cold too fast, but if the QPF bump we're seeing is real, then this could be become a problem.

Typhoon Tip Posted February 5, 2019 Share Posted February 5, 2019 I'd rather not lose power myself... but - anyway, not that we're exactly "riding the NAM" or anything but since we've discussed it .. this 18z run is actually even more QPF loaded with central and E/Ma now approaching 1.25" suggested by the FRH data... The BL looks a tick warmer ... but it's still +1 or + 2 at Logan at the end of 48 hours with moderate fall rates ... The thermal strata is definitely water and not pellets falling ... suspect that's accreting inland though. Link to comment Share on other sites More sharing options...
ineedsnow Posted February 5, 2019 Share Posted February 5, 2019 NAM also moves this in faster.. this run just looks odd to me.. seems the surface should have been colder.. Not expecting much here but some areas north of here could get it pretty good. Link to comment Share on other sites More sharing options...
