Think we will go from like 30-32 at 3pm ish Sunday to 20-25 by 6/7 pm so that will boost ratios and I’m even going to throw out some squalliness as possible
The onset of the cold coincides with the great onslaught if 1994. 8 for a high at DCA and around zero by dark.
1982 and 85 put up impressive numbers same time also
How our arctic express looking ?

it looks like the snow say after 3pm Sunday would fall in rapidly decreasing temps to around 20 before ending Monday. Thats unusually cold so might not 0.2” lq produce 3”+ rather than our more traditional 1-2”
I may now be forever changed. It contains elements I have thought about for years. It may be onto something right now as we are in snow mode until we aren’t. That kind of historical data including even offbeat outcomes will have an effect The joy of me shutting up about models may not be far away.
If that happens I think that would be top 5 coldest snaps since 1990
2018 I think and some I don’t have notes about right now, Feb 2007 I think snd then epic 1994
Finishing this little drive around, It’s still a lot of snow over in most places around Kemp Mill down here in the holler at the head of the crik.
i got a 21 briefly by stables and 23 now in the driveway. That’s 3 degree drop in 45 minutes
