The complex and winter-like storm will consist of three waves of energy, bringing unseasonably cold air to the area by late Tuesday. The first weak wave grazes the northern portion of Colorado tonight, bringing light to moderate precipitation to the area by Monday morning.
After a break early in the day Monday, light precipitation will begin again by the late afternoon and grow heavier as upward motion from the main part of the storm still situated to our west begins to affect the area.
While earlier forecasts had forecast a split tin the wave, current models indicate the wave moving bodily through mid-day Tuesday. As a result, the bulk of the precipitation will fall overnight and snowfall will be decreasing during the day. Temperatures should fall to the coldest levels of the season as skies clear behind the main part of the departing storm.
Wednesday will be cold with our area susceptible to showers in the cold, but rapidly drying northwest flow as a trailing wave moves over the area.
A building ridge should produce a beautiful Thursday. The storm for next weekend looks to be weakening and accelerating so that only light showers are expected on Friday. Seasonal temperatures and dry weather is forecast for the weekend.
Departing storm leads to a beautiful weekend before another significant storm approaches Sunday night

After another 3” fell overnight here on my front deck near the base of the Steamboat Ski Area, drier condition should overspread the area by tonight, although showers will persist at least this morning in favorable, but drying northwest flow.
A beautiful weekend with seasonal temperatures looks to be sandwiched between the currently departing storm and next very significant one forecast to impact the entire Rocky Mountain region for the next work week.
This next complex storm will consist of three waves of energy, with the last bringing unseasonably cold air. The first weak wave will pass over southern California early in the weekend and be over our state by Sunday. Light precipitation may occur over the southern-most areas, but the north will remain dry until the second wave preceding the main event approaches Sunday night.
As this weak wave passes over the area, light precipitation will continue in cool but seasonable temperatures during the day Monday. Meanwhile, the bulk of the storm will continue to develop to our west as the unseasonably cold air associated with the third wave strengthens the storm.
A split develops in the storm as the storm is stretched between the departing second wave and approaching third wave. The third wave looks strong enough to form a closed low that moves over the state on Tuesday. Very strong forcing looks to create precipitation bands which are difficult to localize but will produce moderate to heavy snowfall rates.
The last wave should be east of the Divide by late Tuesday and will finally drag the coldest air of the season over the state, producing significant and likely impressive snow amounts. Wednesday will be cold with our area susceptible to showers in the cold, but rapidly drying northwest flow.
A building ridge should produce warmer than average temperatures by the end of the work week and most of Saturday before yet another storm affects us by Sunday.
