2/19 5:00pm Update: Next Storm/Next Snow Forecast Discussion from the Cherrywood Observatory – February...

With a quasi-stationary trough in the west and variable amounts of up slope flow on the Plains, we'll have rain showers when it is warm and snow showers when it is colder through Thursday early morning. The best shot of snow comes Wednesday PM, but total snow amounts should remain +/- 1 inch. We see 'warmth' at the end of the week and weekend with another shot of showers possible Sunday AM.

Update 2/21 2:30pm: Next Storm/Next Snow Forecast Discussion from the Cherrywood Observatory – February...

Mild quiet weather moves in Friday and Saturday with temperatures quite a bit above normal. Then- much uncertainty awaits us on Sunday. There is tremendous disagreement on the path of the upper level and surface lows Sunday with some models giving Longmont a coating and other models giving us over 8 inches of snow. Some snow chances linger on through Tuesday then we warm up again for quite a while.

Update 2/23 10:30am: Next Storm/Next Snow Forecast Discussion from the Cherrywood Observatory – February...

A storm is moving into Colorado Sunday. That is all we know for sure. How much snow this means for the state...? Oh boy. You can find a model that will tell you whatever you want to hear. We also see a cold front hit Tuesday with TV stations and some models bringing in more snow - other models only see cold dry air for a day. Beyond that we warm up nicely. Oh the confusion.

Update 2/3 10am: Next Storm/Next Snow Forecast Discussion from the Cherrywood Observatory – February...

A winter storm warning is in place for much of Colorado (see text in the discussion). Amazing heat over the weekend will be replaced by amazing cold in just 36-48 hours. We will drop maybe as much as 70F (highs to lows) with strong north winds at times. Wind chills will be dangerous. Freezing drizzle will form (falling on warm ground at first) pre-dawn Monday. Eventually snow will begin falling later Monday into Tuesday with 5-10 inches possible. Once this storm leaves, we remain cold and more snow comes later in the week.

Update 2/10 8:30am: Next Storm/Next Snow Forecast Discussion from the Cherrywood Observatory – February...

As this post goes live, a front is slipping down the front range with a burst of rain/snow associated with it. Temperatures in the 50'sF are getting cut off as cold air flows. Weak up slope flow on Sunday will mean light snow totaling to a coating to maybe in inch in depth by Sunday night. The mountains will still get snow (on top of the many feet they received this week. Additional small snow chances hit Monday night, Wednesday night, Thursday night and next Saturday morning. We remain below normal as temperatures go for the entire next 10 days.

Update 2/13 1:30pm: Next Storm/Next Snow Forecast Discussion from the Cherrywood Observatory – February...

Light snow dusted the Front Range Monday night - now we look out at three more small chances for more snow Wednesday PM, Saturday AM, and Monday/Tuesday next week. Temperatures remain below normal (except for Friday and Sunday when they are back to near normal in town). Conditions are going to go back towards "quiet weather" again.

Update 2/7 10:30am: Next Storm/Next Snow Forecast Discussion from the Cherrywood Observatory – February...

Northwest flow aloft will bring in a LOT of moisture and snow to the northern and central Colorado mountains through the weekend. The drive up there Friday will be ROUGH! On the Plains, a widespread 3-6 inches of snow is expected with jet-stream created banding taking snow totals up to 10"+ for some locations. An overall change in the jet stream pattern will bring on and off snow events for the next 10 days. Temperatures will continue to drop overall through the next 10 days.

Update 9:30am 1/30: Next Storm/Next Snow Forecast Discussion from the Cherrywood Observatory – January...

A couple of weak cold fronts will keep snow going in the mountains the next day or two and finally bring a dusting (maybe an inch in a few spots?) of snow along I-25 overnight Wednesday and again Thursday late afternoon. A serious return of heat takes us into the upper 60'sF for the weekend before a (now looking more significant) possible major winter storm hits Monday and Tuesday next week.

Update 1/27 9am: Next Storm/Next Snow Forecast Discussion from the Cherrywood Observatory – January...

A fast moving upper air trough will begin snowfall in the mountains late Sunday night and keep snow falling through much of Monday. Light rain showers and snow flurries in the air are possible down along I-25 and on the Plains. The ground is too warm and dry for snowfall accumulation. Tuesday is warm and dry before a brief, somewhat stronger, system hits Wednesday night for a chance of a coating of snow. Then we really heat up with possible 70'sF next Sunday! What kind of winter is this anyway?

Update 2/16 9pm: Next Storm/Next Snow Forecast Discussion from the Cherrywood Observatory – February...

With hit after hit of snow past us now, we have a quiet and warm (overall) weekend ahead of us. Our next stormy period runs from Monday morning to Wednesday morning when we may pick up an couple inches or a bit more of snow. Then we return to quiet conditions again beyond that!
