I’ll mainly work with the scattered snow showers today. We will have two periods of instability/lift over the state, one in the morning and another in the afternoon. With reinforced cold air, we’ll be cold enough for snow. Even if it is only snow flurries in the air. The favorable mountain slopes may see up to 4″ of snow, but nothing measurable should build up on the Plains or along I-25. It will be cold and blustery though, with less sun than we saw on Wednesday.
Figure 1 shows that there will be scattered showers all across the northern mountains and NE plains. Anyone around might see a few periods of light snow.
Figure 2 is the GFS take. The gap along I-25 seems to be the snow-depressing effect of down-slope flow, but snow flurries are still possible in Longmont. Figure 3 hints that a coating is possible IF everything went right for snow for us.
The Longer Range Forecast:
The ridge will build in from the west – which will give California a break from the destructive Santa Ana winds, and will warm us nicely for a beautiful weekend. More on that later!
