Forecast Discussion:
Sunday AM Update:
Figure 4 is the snowfall reports map from CoCoRaHS. I drew some quick and dirty isohyets (line of equal precipitation - snowfall in this case). The 2 inch line cut Longmont in half. Parts of Boulder reached 5 inches of snow (Figure 4).
Ft Collins received 1.5-2 inches of snow. Berthoud about 1.5 inches. Estes Park only 1-1.5 inches (in the reports submitted by midday; Figure 5). North Denver was also low in the 1-2 inch area while the southern side of the Metro picked up a much nicer 3-5 inches (Figure 6).
Previous Forecast:
The current storm is underway, so this discussion will be brief. I'll upload Sunday morning snowfall report maps as an update midday Sunday.
Figure 1 shows that the models are still expecting one more burst of snow in the early evening before skies clear Saturday night. From my latest look at the radar - I don't see this band of snow upstream anywhere. Figure 2 is the rapid update model HRRR and snow through Sunday morning. Longmont is on the edge of 0 to 1/2 inch more. The main activity has shifted south.
The longer range forecast:
Figure 1 shows the weather 10 days out... there are low chances of precipitation Monday, but temperatures go quite low for a day. We see chances of snow/rain Thursday into Friday and again Sunday into Monday. Only the most distant storm looks significant (and we know what usually happens- this year- to good looking model-storms). Figure 3 reflects that idea by giving us a total of about 8 inches of snow over the next 10 days. I would be really surprised to see that much occur out of these next three unsettled periods. (Nice snow in the mountains though!).
