December 2016 Observations and Discussion

Only made it to 32F today with a heavy overcast which helped mitigate any snow melt.  The snow pack has settled and become denser over the past couple days.  If we can add some snow on top of this snow cover with the Fri/Fri night system, I think there is a chance some in our region could spare a brown Christmas???

GEM lollipops Chicago with 4" Friday.

 

 

 

I'm not from the Midwest (visiting Chicago from Seattle) but this seems like a very odd system.

 

Models tend to have a very difficult time forecasting open waves like this, so I wouldn't expect to be too confident in the outcome till Friday morning. Even after that, there will be a lot of radar/thermometer watching to see where any bands may setup and if any mixing occurs through the column.

 

Looks pretty good for a solid 1-3" system over a relatively large area, but there is definitely potential to bust in either direction if surface temps remain just above freezing or some decent banding sets up.

Sure was.

 

That thing was insane. We got 4" of solid sleet at my aunt and uncle's house in Evanston. Perfect timing during the day too. I was worried the winds off the lake would cause mixing issues, but we hung at 31-32 all day.

 

I shovelled their place and their neighbor's and I swear that stuff had the density of the sun.

DMX regarding Friday event:

Each run continues to latch on to more

available moisture which is troublesome because if the moisture

syncs well enough with the forcing and dendritic growth zone(DGZ),

this could become a headline event for snowfall. right now have

general 1 to 3 inch amounts mainly focused over the northeast half

of the forecast area.
