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!

He is in his 14th year running this review. He is an astronomer (from the 2nd grade onward) and became a meteorologist (in the 5th grade) when a thunderstorm in Arizona rained on his telescope when the weather service had only forecasted a 10% chance of rain. He has college degrees in physics and astronomy and climatology and a graduate degree in meteorology and earth science. He lectures at the Little Thompson Observatory in Berthoud, the Estes Park Memorial Observatory in Estes Park, and for a number of online universities. He built and runs a backyard observatory near Pace and 17th in northeast Longmont where he has lived for 8 years with his wife, daughter, son, and two cats. Invitations to open house nights at this observatory, LTO, and EPMO will be posted with future discussions when they are scheduled. Forecasting severe weather and snow amounts via text lead to this column. He began texting friends about the weather right after the September 2013 flood. The readers of this column will, hopefully, keep him honest in what he ‘thought’ he had forecasted for ‘the most recent’ storm.
