The Forecast Discussion and longer range forecast:

10pm Update:

The storm started out with cold rain overnight - then a period of freezing rain/drizzle (my airplane was ice coated on the north side at our 10am takeoff. Then there was real snow.

Unlike the last storm (that overproduced on most forecasts) - this one spent a lot of its water content in that earlier rain and freezing rain.  Snowfall totals were at the low end.

Longmont received about 1/3rd to 1 inch of snow 7am yesterday to 7am today (Figure 1 update).

Figure 1 update: The CoCoRaHS snowfall total 7am Saturday to 7am Sunday. for Boulder, CO.

End 10pm Update.

The drizzle, ice, and snow continues as I write, so I'll update later day with storm reports.

This fades out by the time this post goes live (and I'm traveling for Thanksgiving currently). We are mild and dry UNTIL next weekend when another snow storm has appeared.  It is always best to look at the NEXT storm after the NEXT storm is done.

Enjoy this nice work week, at least!
