Friday Update:

Astonishingly long stretch of quiet weather and above normal temperatures.  Hoping for more snow in Thanksgiving week!

End Friday update.

Sunday update:

The models are coming more into agreement for the Wednesday/Thursday cool down and chance of precipitation (Figure 1 update). The cold front arrives around 2pm on Tuesday.  This doesn't look, at this time, to be a very wet or very cold storm. Some snowfall is possible at night.  More later!

The Longer Range Forecast:

A trough finally approaches the state mid-week (Figure 2). The GFS has snow/rain chances looking very spotty at this time (Figure 3). Over the next 5 days, the precipitation remains in the mountains, and very light (Figure 4). That falls as light snow amounts (Figure 5). There is a hint of more mountain snows over the next 10 days, but overall, things are very quiet.  Enjoy a warm late-fall.
