What?! I just put snowfall totals up in Sunday’s forecast discussion from our last storm and ANOTHER front and storm is moving in for Monday (today). Figure 1 is the (long ignored here) water vapor satellite image showing our next storm, circled in green, rolling towards us.
The trough driving that will be over the Great Basin by this morning (the big red line -Monday AM – Figure 2). The front will be through late Sunday night and temperatures drop into the 20’sF for a high today. Very similar to our last storm, we’ll see up slope flow and periods of freezing fog and freezing drizzle again. Figure 3 shows the front past Longmont Monday morning and a good amount of snow on the Western Slopes. Figure 4, Monday evening, shows ice and snow snow spreading out onto the Plains of NE Colorado.
Figure 5 is the GFS’s take on snowfall. Some choice spots in the West and high mountains will get a foot. Ft. Collins might see 1/2-1 inch, but Longmont is in the dusting to coating area. Denver might see a coating to an inch of snow while Estes Park might get a couple of inches. This is also not a big storm.
The longer range forecast:
Our next storm comes in with a trough pushing in Wednesday giving what “looks” like a 1-3″ storm on Thursday.
