Forecast Discussion and Longer Range Forecast:

2:30pm Update:

Though temperatures remained above freezing and we didn't get much snow north of Denver, we did get good and welcome moisture.  Longmont got 1/3rd to 1/2 inch of water. Boulder received around 3/4th inch of water (Figure 1 update).  For snowfall, Longmont got a trace to around 1/2 inch (that was washed away by rainfall).  Boulder got about 1-4 inches of snow. The foothills to the west of Boulder received up to 9 inches (Figure 2 update)!

Denver saw 2-5 inches on the eastern side while the western foothills picked up 7-12 inches of snow (as did the Palmer Divide). Berthoud to Ft. Collins only saw a trace to 1/4th inch of snow.  Here's to hoping for more next time!

End 2:30pm Update.

The storm is ending tonight.  I'll add precipitation reports here in the later afternoon once most of the reports are in.  Obviously, temperatures around Longmont to Ft. Collins were way too warm for anything more than snow in the air and a brief build up of almost 1 inch (that washed away with a return of the rain).

We needed the water though!

Figure 1 shows the storm ending rapidly Friday night.  Temperatures are not expected to get into the 50'sF this week now. Is that another storm next week that may matter???

More tomorrow!
