Forecast Discussion:

7PM Update for Storm Snow Totals (2 days)

I conducted an eyeball estimate adding the values from the first day of the storm (pictured) to the smaller totals seen before 7am this morning and wrote them in large blue numbers.  This is just to get a feel for some of our surrounding communities (there was some melting, sublimation, and compaction, of course). Figure 1 update, Figure 2 update, Figure 3 update.

This storm over produced compared to my prediction, and that of some of the models.

Figure 1 update: CoCoRaHS new snow totals as of 7am Sunday with eyeballed additional snow by city through 7am Monday. Boulder County.

Figure 2 update: CoCoRaHS new snow totals as of 7am Sunday with eyeballed additional snow by city through 7am Monday. Larimer County.

Figure 3 update: CoCoRaHS new snow totals as of 7am Sunday with eyeballed additional snow by city through 7am Monday. Denver Metro.

End 7pm Update

I'll update this post in the AM when the storm pulls out with snow totals. In the meantime, we return to normal temperatures and dry weather very quickly for most of the next week (Figure 1).

Quiet and pleasant (a bit of a chill with a dry cold front next Saturday).
