SWFEs follow a lower ratio?

Generally yes. You have warmer air overrunning the lower cold dome so that 850-700 layer typically quickly climbs above the -12 to -18C max DGZ. Sometimes you can start with initial decent ratios, but eventually the 9-10:1 piles on top of it. There’s other caveats like secondary lows and if it’s a very cold SWFE (think snow starting with temps near 0F in our area) so that there’s a longer period of overrunning lift in the DGZ. But generally it’s a 9-12:1 ratio snow before any possible sleet moves in.

If it is a swfe redeveloper we can start taking this seriously tomorrow nights runs Tuesday morning 

I think Wednesday at the earliest we take it seriously.  There’s a strong pressing trend.  It would seem unlikely to have it go too far south but we’ve seen that before especially during 2003-04.

I’ll believe it when I see the snow falling. This keeps happening, the models show big snows a week out and then the rug pull happens in the short range. Can’t even trust it even 1 day out, the gfs and euro had me getting a fairly significant storm last time and I only got a minor snowfall.
