IR satellite shows the high cloud tops associated with it (I'm kidding but maybe not. Full weenie mode tonight) I like to see the mix line taking on more a SW to NE v W t E trajectory. That’s more a winning scenario for along and west of 95 3 Link to comment Share on other sites More sharing options...
clskinsfan Posted February 18, 2021 Share Posted February 18, 2021 0z HRRR is much better for my area. Comes in hot and heavy. Less sleety for the District I think. 1 Link to comment Share on other sites More sharing options...

Cobalt Posted February 18, 2021 Share Posted February 18, 2021 Not sure if this has been posted yet (and if so I can delete it, my apologies), but here's DT's final call. Seems pretty within the bounds of reason for most. 29/14 here. Hope everyone gets their fair share of snow! This stretch has had a lot of ups and downs, but it's nice that we willed a rainstorm our way for once 4 1 3 Link to comment Share on other sites More sharing options...
Roger Smith Posted February 18, 2021 Share Posted February 18, 2021 DT looks fairly solid to me, would loop that 1" line around western Lake Ontario and put a 3" lolly in there, get some clients in Hamilton, football capital of Canada. A town near there has had 3 feet of snow in the last week mostly from lake effect in east winds. 1 1 Link to comment Share on other sites More sharing options...

osfan24 Posted February 18, 2021 Share Posted February 18, 2021 NAM actually looks interesting to me. Snow/mix line trajectory seems more NE/SW than E/W. It's still too far west, but it seemed to try to stay all snow for 95 and west. Didn't get it done but was interesting to see that change. Link to comment Share on other sites More sharing options...
