snowmagnet Posted January 18, 2019 Share Posted January 18, 2019 The NWS forecast for Fairfax is snow with rain and snow on Saturday, changing to rain Saturday night, with a high of 41 before dropping through the day on Sunday. That is significantly colder than the 50’s that was forecasted earlier in the week. My concern is the icing Sunday and Monday, even in this area, from the rain plus the melted snow. I would think there would be more advisories on Sunday for our area. Link to comment Share on other sites More sharing options...
WEATHER53 Posted January 18, 2019 Share Posted January 18, 2019 Models having hard time with lurking arctic blast, snow cover, and assertive cold high pressures in general perhaps we spike in next two hours but forecasts yesterday for this afternoon were highs in upper 40’s and were in upper 30’s so far. This is not garden variety cold lurking and really any high pressure that we have had for these events has been suppressive. There have definitely been stone cold cutters but we are not in that kind of pattern now. Link to comment Share on other sites More sharing options...

Expand Not really buying that. I get the idea that any CAD would scour out more quickly (or never exist at all) at 3200 feet, but we're not talking about CAD with the snow scenario, and even if sea level at that latitude is in the 40s, it seems unlikely that the huge different in elevation would result in so much less accumulation in Tucker than in Garrett. In the vast majority of scenarios, Canaan sees more accumulation than Garrett (though there are certainly some exceptions). Link to comment Share on other sites More sharing options...

Steve25 Posted January 18, 2019 Share Posted January 18, 2019 I'd rather be in Baltimore than NYC for this storm. At least I know well in advance that this is mostly a rain threat down here. They're on the edge of their seats up there. Honestly based on the models, no matter what they get on the front end, it looks like it'll change to a HEAVY rain and that sounds nasty. Boston looks like they're right on the edge of either a monster snowstorm or changing to heavy rain. Link to comment Share on other sites More sharing options...

Expand Currently 37/32 here. The 1.2"-1.5" that fell overnight has long melted away, but we still have about 2/3 of the snowpack from last weekend on the ground here, which means ~2"-3" where it still exists. Interesting that forecast called for temps in low-mid 40s today, but we're just not getting there...probably has no impact on what happens tomorrow/Sunday (especially here in NoVA), but...interesting. So, @mappy, just what DO you have on the ground at home in terms of snow? I've caught spotty updates in several topics over past 1-2 days, but still don't have a clear picture on what white stuff (if any) is actually on the ground in your area, on over to @psuhoffman-land after last weekend and last evening.
