The first model run of the day the 12z NAM which is a bit out of it's range has temperatures here at the surface staying below freezing all day Wednesday and through around 8 or 9am on Thursday. While that is happening warmer air will be moving in above us at around 5k feet. Meaning by about 4am on Thursday morning temperatures will be well above freezing where snow is made. This means whatever falls after that time will be some form of non-snow meaning sleet or freezing rain. Then it will be a race to see how we get the surface to warm for plain rain.image.thumb.png.f7fab72e20a5c4c9ec336d72cd06cd59.pngimage.thumb.png.903f76d41409c6ebcb3f39864b05bac8.pngimage.thumb.png.197b3c69254537b05d58bc21c21cc166.png

The latest GFS runs has 4 winter events with all but this weekend's event having snow accumulation as part of the mix. This weekend on the model looks like mainly freezing rain changing to rain. Below are the 3 individual model snow events with 2 day totals over the next couple weeks. NOT A FORECAST! The first snow event is this Thursday. #2 is next Wednesday/Thursday and #3 is the weekend of the 14th-15th.

If the last 2 storms happen, when are we going to have our parade for the Eagles Super Bowl victory?

The snowfall maps for the GFS are cracked out because they are showing a lot of sleet accumulation.  Conditions for a couple of those events don't support a moderate snowfall solution.  In other words, they can't really be trusted right now.

The longer term pattern looks more interesting, but there's a chance of an all-snow event next week prior to or around Valentine's Day.

The GFS has several discrete events over a few days, but I think that might consolidate down into two - mid-week and then a weekend something.  The Euro is keying more around the 12th/13th and then there's less consensus for a weekend event.

Either we're about to experience one of the better patterns around here in years OR we're on the verge of one of the biggest head fakes/rug pulls of all time. Place your bets!

I dont think it's a head fake wrt the hemispheric pattern and favorable teleconnections, though I could see us getting screwed with sleet and rain right before the cha ge, then suppression with the actual pattern in place, and lastly missing archambault event when it all breaks down circa march 2001. 

Yep, I said it.
