The Front Range Forecast: Small storm now, larger storm later

In Brief:

A small storm moves by Sunday/Monday followed by another warm-up.  Much better snows possible Thanksgiving night.

Forecast Discussion:

A quick moving, weakening system, is sweeping the state Sunday night and Monday morning.  There are very low chances of rain (overnight flurry?) along I-25 (Figure 1).

Showers will be scattered and mainly found in the mountains (Figure 2). The GFS does not give areas north of Denver any measurable snow (Figure 3) or rain (Figure 4). We warm up again through Wednesday (Figure 1).

The Longer Range Forecast:

The next series of cold fronts begin to hit Thursday/Thanksgiving and Friday dropping temperatures to freezing levels for highs (Figure 1). This is a slower and larger system than the current one (Figure 6) powered by a deep upper air Low (Figure 5). It looks like mountain locations get 4-12 inches in spots while areas along I-25 may see a 3-6 inch storm.  I'll keep you updated with a Snowfall Roundup later in the week.
