Forecast Discussion:

There isn't much to cover this weekend.  A minor trough will pass over Colorado Sunday/Monday (Figure 1) kicking off a rain/snow mix in the central and southern mountains and western slopes of Colorado Sunday (Figure 2).  A bit more snow falls in the mountains Monday (Figure 3) but the Plains remain mostly dry (maybe some sprinkles??).

The Longer Range Forecast:

Temperatures for the next week bounce around the upper 50s (close to normal) to the mid 70s along I-25.  The mountains and Palmer Divide get some moisture, but snowfall will be confined to the higher elevations.  Enjoy Spring as it begins!
