Here we go! Lots to talk about today.

The pattern is changing and it looks like it’ll stay a little more active through the next 10 days!
any pow lovers will like (not love – but definitely like) this forecast.

Here’s what’s happening:

There’s a nice little trough of low pressure impacting the Great Lakes and Northeast on this Tuesday PM (this was the big blizzard that halted travel back on Sunday). That storm is moving out which means Colorado is on the rebound in terms or temps and moisture chances.

HOWEVER – this big blizzard paved a pathway for more storms to ride along. Those deets are below.

We are in a NW flow thanks to a ridge to our west. This NW flow is funneling some moisture into the state. Moisture, moderate to strong winds and a mountainous terrain have subsequently allowed a mountain wave to form keeping our temps a little cooler today. Tonight, the clouds will act as a blanket keeping our temperatures slightly warmer than what we woke up to Tuesday AM. Most areas in the mountains and the plains will stay dry – but with the flow coming from the Pacific – moisture will creep into the state into the overnight hours.

Wednesday morning – the NW flow turns more westerly or zonal which keeps a steady stream of moisture aimed at the Western Slope of OC – the northern and central mountains will likely wake up to some isolated to scattered snow showers. This won’t amount to much but some places (mainly higher elevations) could see 1-2″ of snow on Wednesday.

The aforementioned zonal flow is a pattern that will continue for Thursday and Friday until a stronger and developing low forms. Flow from the due west will allow snow to accumulate for all of the CO mountains! Totals for Thursday to Friday are looking to be in the range of 3-6″ for most mountains. Favored slopes and highest peaks may get 6-10″ of accumulation by Friday PM.

Now the fun starts. A weak trough with decent moisture and will develop over the Four Corners and allow for more significant snow to form. This trough has enough moisture and has a decent motion across the state to produce snow for almost everyone in CO for this weekend.
This storm is slightly trickier. Several models are thinking that there will be ample moisture, others think otherwise. So, until we see this little chunk of energy begin to develop (which looks to be towards Friday PM – we may not have an amazing handle on how much snow will fall and who will get what. For now, just prepare for the possibility of accumulating snow across the Centennial State.

Thanks to this active pattern – temperatures will also be falling through the week. Expected highs to dip into the 30s/40s by this weekend for the Plains. 20s/30s for the mountains. Overnight lows will fall into the 10s/20s for the plains by the weekend. 0s/10/s for the mountains.

Look for more info about this weekend coming up.
