Some light snow likely Saturday, cold and dry after for a while--

A clipper type system should impact our area Saturday with a period of light snow and flurries now likely late afternoon and evening. I'm only expecting a dusting to an inch accumulation. I've attached a precipitation map from the early morning run of a model called the GFS--it shows about a tenth of an inch liquid, which matches my thoughts.




From there--cold is the word. Some lows in the TEENS and highs struggling to get past the mid 30's a few days.
Some early indicators show potential 10 days out for a storm. 10 days out means very little other then look for future updates.

Last year, it was an El Nino winter and we had plenty of action in the subtropical jet, this year--la nina, (Colder water near the equator relative to normal) sets up a different type pattern and we tend to not have as much energy in the sub tropical jet. Basically, I would not be shocked if we remain cold and dry.
