clskinsfan Posted January 23 Share Posted January 23 The precip in the middle of the country certainly looks more robust than any model I have seen at initialization. Tons of juice out there. 4 Link to comment Share on other sites More sharing options...

Not as extreme as at 12z. But still there. So not sure how much to trust either the 12z or 18z snow map. Link to comment Share on other sites More sharing options...
jayyy Posted January 23 Share Posted January 23 Internal model snow ratio map is even better than Kuchera. It’s very hefty with the front end thump. Wish it wasn’t at range, but something we’ll be monitoring is the QPF distribution on guidance to the lead up. If they stay juiced, that will be a major plus for snowfall and beating back the mixing line due to evaporative cooling in the layer between 850-700mb. It’s output makes sense given what it does over the next 24 hours out west… but boy, is it on an island… let’s see a RAP run like this tomorrow and we’ll maybe be onto something. It has a wicked front end thump 1 Link to comment Share on other sites More sharing options...

T. August Posted January 23 Share Posted January 23 Honestly doesn’t really matter too much but GEFS is a slight improvement for southern areas. Link to comment Share on other sites More sharing options...

WxUSAF Posted January 23 Share Posted January 23 I feel like we’re just windshield wipering a bit now. With 12z we thought maybe we were inching in a better direction and now 18 has been mixed. Seems like mostly it will come down to how thumpy things are and when we precisely change to sleet. 4 3 Link to comment Share on other sites More sharing options...
jayyy Posted January 23 Share Posted January 23 Feeling pretty good about 10-12”+ in my backyard. Call me crazy but I still think the Columbia and EC area has a SHOT at a foot if the RAP is onto something with the mega thump to kick things off. 1 Link to comment Share on other sites More sharing options...
clskinsfan Posted January 23 Share Posted January 23 GEFS snow depth mean is still nuts. It definitely decreased from 12Z though. Link to comment Share on other sites More sharing options...

Call me crazy but I still think the Columbia and EC area has a SHOT at a foot if the RAP is onto something with the mega thump to kick things off. 6-12 is the forecast for here. I will expect closer to 6, but if precip comes in hot and heavy as some runs have shown, upside might be better. 1 Link to comment Share on other sites More sharing options...
RDM Posted January 23 Share Posted January 23 Been working outside all day at home. The front went through a while ago with a burst of wind from near dead calm conditions. The gust was clearly cooler than the ambient air it was replacing.. How much I don't know - but it was a pretty cool experience we don't get much around here.. 2 Link to comment Share on other sites More sharing options...

Almost a cold feedback cycle. I'm so glad to see this. I've always thought or assumed that snowpack positively impacts ground temps (or negatively depending on how one would view it) so seeing this confirms an idea I've never been able to confirm as gospel... so, thank for this, frd! 1 Link to comment Share on other sites More sharing options...

Call me crazy but I still think the Columbia and EC area has a SHOT at a foot if the RAP is onto something with the mega thump to kick things off. I think 12” is pretty unlikely unless we hold onto good ratios for awhile or something early. For eastern HoCo, I think 6-8” of snow and 1-3” of sleet. So I think double digit accumulations are certainly possible. Max snow DEPTH might never much exceed 6-7” though. Once the pingers start, we’ll compact a lot 3 Link to comment Share on other sites More sharing options...
