Forecast Discussion:

3pm Update.

There was a coating of snow in the evening in Longmont while Boulder, that normally gets hit, saw nothing.  The nearby foothills only pulled 1-2 inches.  It turned out to be pretty minor overall.

Denver saw a trace to about 2 inches (down in the SE).

Estes Park stayed below an inch. Berthoud received a trace of snow.  Ft. Collins saw a trace to 1/2 inch of snow in spots.

End 3pm Update.

The storm is underway, and I drove through some lowered visibilities in blowing dust, snow, and tumbleweeds. Crazy! My forecast is a bit tarnished by a trace of snow building up in places as of 10 p.m. We'll see if more happens overnight. I'll update this post with snow totals later today.

The short range GFS and HRRR models still show no notable snow in Longmont (Figures 1 and 2) but heavy squalls can still make it to the ground. More tomorrow!

Figure 1: The forecast accumulated snow map from the GFS and weather5280.com for Colorado for the next 1 days, through Sunday evening. Longmont is the pink dot, as always.
