Baltimorewx Posted January 23, 2021 Share Posted January 23, 2021 Now that it’s coming in range I think 3K NAM is the way to go with this one...I just don’t see the onset being snow with the timing mid afternoon and the low that far west. 3K starts as sleet/ice for cities then goes to rain after a few hours. Definitely could be a fairly significant ice situation for the usual spots with this one though but I just don’t buy the couple inches of snow that some modeling has spit out with this one Link to comment Share on other sites More sharing options...

You are basically in a totally different climate zone from these people. Greatest ice storm of all time. My young family and I were skiing at Waterville valley in New Hampshire. The night before the storm hit Philly the temperature hit minus 32 degrees at Waterville. The next morning it was 20 degrees in Philly. And poring rain. We drove home two days later and the freezing line with ice was brutal. We lost several trees north and west of Philly. Everyone lost trees. The second greatest ice storm happened around 2011-2012. A little north of us. Closed 78 and Lehigh university. A bunch of my daughters Sorority sisters came to stay with us. That was not to bad. lol Link to comment Share on other sites More sharing options...
CAPE Posted January 23, 2021 Share Posted January 23, 2021 The trend for drier continues, esp the further north you go. The wave is moving into lots of dry air and high pressure, and looks to dampen. This is what i thought would be the most likely outcome a couple days ago, but the models trended the other way. Now trending back towards weak/de-amplified. This has been the case with nearly every wave attempting to move eastward in this current pattern. Link to comment Share on other sites More sharing options...

Yea but what good does it do anyone if the level of suppression it takes to stay cold also squashes everything to your south. Look at the axis of qpf. Guidance nailed that from day 10. But that band over northern VA was supposed to be snow and historically it SHOULD be! This is about the 5th storm this cold season that lacked any appreciable snow shield to the north of it at our latitude because the cold and precip never touched!

These boundaries, even now, are lacking the potential energy they should have with a greater temperature gradient. It’s a little better now. At least the waves aren’t squashed to LA lol. But it’s still not enough to get them to amplify much given a suppressed flow. Link to comment Share on other sites More sharing options...

Strongly agree. 250mb winds are ripping as well and aiding in the shred process. The trend has been for sheared and weak, fast flow. Link to comment Share on other sites More sharing options...

Baltimorewx Posted January 23, 2021 Share Posted January 23, 2021 GFS keeps the theme of this being mostly an ice situation. My bar with this is a couple sleet pellets and a glaze of ice on tree branches over here by the bay lol Link to comment Share on other sites More sharing options...

Do I want a north trend? But since the precip is WAA driven if that shifts north the thermals shift north and I literally don’t have any room to give.

Failure. I think this one was always destined for failure, no matter what. That is, if one was hoping for any significant snow. Me?

Hurricanegiants Posted January 23, 2021 Share Posted January 23, 2021 Scratching my head trying to understand this. 40 plus years here. And here we go again with the average of 50 degrees after this week as we roll into February. Frustrating. Holding on for a few inches this week.
