Next Storm/Next Snow Forecast Discussion from the Cherrywood Observatory – March 4, 2019

Forecast Discussion:

I think I need to recover from all that forecasting excitement, so tonight we'll look back on what did happen. For the three reporting graphics below, add about 1 inch in your mind to make up for compression of the snow over this long event. (I've spot added the two-day totals and 1 inch added to the totals below seems to do well to 'correct' the data.)

For Boulder county (Figure 1), Longmont received about 5 to 5.5 inches while Boulder received about 6 to 6.5 inches of snow. In Denver proper (Figure 2), spots in western Denver seem to have approached 6-8 inches while areas around DIA pulled about 4 inches. Up in Larimer county (Figure 3), Ft. Collins was graced with 7-8 inches and Estes Park pulled a whopping 12-15 inches. RMNP must be impressively buried (Figure 3).

We are very cold today lingering in the lower 20's F with a near zero morning (it is already -1 in Longmont as I type). We'll briefly climb to freezing tomorrow in spite of sunny skies.

The longer range forecast:

We return to near normal temperatures (highs around 50°F this time of year) by Thursday with very small chances of snow flurries Wednesday PM and Friday PM (Figure 4). There is nothing big on the long range models at this time. Be careful shoveling or sweeping this powder away.
