Heavy snow with rates in excess of an inch an hour started in earnest around 6am this morning along the urban corridor. Snow will continue through the day Sunday, with 6 - 12" possible by Sunday night. Locally higher amounts are certainly possible with this storm. Radar shows northeast Colorado completely socked in at this hour.

Images will be added to the live stream throughout the day, as well as updates on all the very latest as needed. Here is some footage I took from around Denver this morning, showing snow accumulating rapidly! More video and photos to come!

Enjoy the snow!

NWS issues Winter Storm Watch ahead of rapidly developing winter storm
Totals forecast from Matt Makens 7NewsA winter storm headed for Colorado over the next 12 to 36 hours has the potential to bring significant snow to the Front Range urban corridor -- in fact, quite possibly, the heaviest snow thus far this season. Model spread over the last 12 hours has been anywhere from about 4 inches in the city to over a foot. With that said, our snowfall forecast has been upped to 5 to 10 inches of snow for Denver, with the potential for higher totals, especially to our south and east. These numbers are subject to change as the day wears on, and given current trends, they could change up. Double digit snowfall totals certainly not out of the question, but let's not get ahead of ourselves.

Snow is expected to start around midnight tonight, then become heavy at times through Sunday morning. Best chance for the heaviest snow, where rates could exceed an inch an hour, will be during the very early morning hours Sunday.

The other story we are monitoring with this system is the wind. A Blizzard Watch remains in effect for communities along the Palmer Divide, where sustained winds could cause poor visibility and dangerous driving conditions for a prolonged period of time. In Denver, wind will also cause blowing snow and at times poor visibility, especially during periods of heavier snow.

Snow should gradually diminish late in the day Sunday, before coming to an end Sunday night. In its wake, below normal temperatures will stay with us, and last through at least the middle of next week. With fresh snow cover, single digit lows are likely again by Monday/Tuesday.

This is a rapidly evolving situation that should be monitored closely as the day wears on. Expect updates as necessary over the next 12 to 36 hours, with any adjustments to snow totals and the latest winter weather advisories.

Another winter storm takes aim at Colorado
ECM snow totals through Sunday With this week's snow all wrapped up, it's time to start looking ahead to our next set of disturbances headed for Colorado. The first will be this afternoon when a fast moving disturbance could bring a quick snow shower or flurry to northeast Colorado. Little to no accumulation is expected, but temperatures will remain chilly, with breezy conditions possible.

Our next shot at snow comes late Saturday into Sunday. Consensus between the models at this point is actually quite good. Each model has the best chance for heaviest snow totals south and east of the city, across the Palmer Divide. A Blizzard Watch has already gone into effect for these areas where snow and blowing snow looks quite likely, with upwards of 6 inches possible by Sunday night. In Denver we are a bit more on the fence with regard to heavier snow totals. For now, 2 - 5 inches looks completely reasonable for the city, but if we can harness some better upslope then these numbers could be higher. No watches or advisories have been issued for Denver at this time.

It is worth pointing out that there are some pretty gung-ho model solutions out there, which if they verify, would bring a nice wallop to Denver. On the flip side, everyone's concern (if you are hoping for heavy snow that is) should be if a more southern track takes shape. This would greatly reduce snowfall potential in the city.

A long way to go, a lot more data to crunch. Stay tuned for the latest on this developing winter storm!

Difference of a few miles could mean difference of inches
We are all set to get some snow in Denver tonight, and with any luck at all it will be the most many of us have seen from a single storm in a year. Models have been pretty consistent in bringing between 3 - 8" of snow to Denver, with the heaviest totals south and east of the central city. The image to the right shows the 12z GFS snowfall forecast. Two takeaways from this. . . One, this particular model has been pretty insistent on bringing some pretty heavy snow to the eastern and southern suburbs. The second, is that the cutoff for the higher totals is quite dramatic as soon as you get west of I - 25.

All models are in general agreement with higher totals south and east of the city, but hopefully it will not be nearly as extreme as the GFS shows. Here is the forecast map from the National Weather Service in Boulder. This scenario paints 4 - 6 inches for central Denver. Good chance a lot of us end up on the low side of that, but please note the potential for significant snowfall around the greater metro area.

I am interested to see how this afternoon's models differ from this morning's. I suspect not too much, but it would be reassuring to see some bring a bit more snow west of I-25.

Radar already showing some echoes southwest of Denver at this hour, with snow becoming widespread as we head into the evening hours. Snow will diminish through the day Thursday.
