Heads up, there may be fresher snow! Read the latest Colorado Daily Snow

Quick update this afternoon...

The storm is going about as planned. Wolf Creek picked up a quick 6 inches through 3pm and they'll likely see another 4-6" through this evening before the winds shift.

Elsewhere snow showers are falling though the best accumulations will wait for this evening as the atmosphere saturates and the winds shift to the west and northwest.

Updating my forecast from this morning, I don't have any more of a clue as to where the band of snow will set up overnight. Expect a few inches, but really hard to know exactly what will happen. There's a better chance for more widespread snow on Thursday as we get a bit of a stronger wind from the northwest and increase the orographics.

Since I pegged Sunday as a big day, much of my attention will focus on looking for clues that will prove this forecast wrong. Today's European model drops the Saturday night storm down further to the south which is not good for the I-70 areas to see as much snow on Saturday night, but the American GFS and NAM models are holding steady on their northern track, and the GFS has been much steadier than the European which is flip flopping a bit. Also, the UK model and the US Navy model agree with the northern track, while the Canadian model is pushing the storm south. If you're keeping score, that's 4 models in favor of a bigger storm and 2 models in favor of a more southern track. However, the models that have been in favor of the northern track have been steadier in their forecast, so I'm leaning on them a little more. Plus the Canadian model (which is showing a more southerly track) is usually out to lunch (don't tell them I said that).

I'll keep updating you. The last thing I want to do is to be the boy who cried wolf and over promise Sunday and not deliver, so I'll let you know if anything changes. So far, so good:-)
