Before we look at our very small chance of snow Saturday night, let’s look at the season snowfall to date (Figure 1). My home, in NE Longmont, has received 45.2 inches of snow since September (that is amazing to me too). That matches the purple shade for Longmont in this figure. Places in the mountains have received tremendous amounts of snow. Overall, the state is at 111% of normal as snow fall goes. Good news.
Today (Saturday) temperatures return to just somewhat below normal for the date – Figure 2 (about 48°F for today). The cool front passes around 3 pm.
The longer range forecast:
Figure 3 is the upper-air pattern for Sunday showing a trough passing and a deeper one approaching from the west. The problem is there is little moisture expected to be available to the system east of the Rockies. The mountains will keep getting shot after shot of new snow. The surface map for Sunday am (Figure 4) shows precipitation remaining over the western slopes and higher mountains and northern Colorado Rockies. We ‘may’ see some snow sneak off, but it won’t be much. Figure 5 is the GFS take on snowfall over the next 5 days. We have a coating to 1 inch touching the eastern side of the town and just down the road in Boulder.
After this weekend, we bounce around in the 30’s F and 40’s F with our next chance of snow coming Thursday. More on that later!
