6-12" of Wind-Whipped Snow Thursday
Winds to 50mph, Windchills to Zero Possible

After digesting the most recent model guidance, I'm comfortable with my earlier first call of 6-12" in the general Denver metro area. It's still a little unclear where the highest amounts are likely to be, but if I'd have to guess it would probably be right up along the foothills as well as areas south and east of Denver around the Palmer Divide; (this is subject to change however).

Note that whiteout conditions are possible at times on Thursday with occasional wind gusts to near 50mph and wind chills to ZERO at times!

Here's how I see things unfolding...
  • Showers of rain and wet snow Wednesday evening change to all snow after midnight
  • Periods of moderate snow overnight with dropping temperatures
  • Several inches of snow possible by dawn Thursday
  • Moderate/heavy snow Thursday + falling temps to near 20 by late afternoon
  • Winds gusting to 50mph at times may create whiteout conditions
  • Significant accumulations during the daylight hours Thursday
  • Major ground and air travel disruptions are possible
  • Snow continues moderate to heavy into Thursday evening
  • Snow tapers off (generally) from NW to SE by around midnight
  • Bitterly cold temperatures in the single digits by dawn Friday
Once again, at this time I'm generally expecting 6-12" of snow across the greater Denver metro area. It's possible that some places may see a bit less than this and that others may see more , but 6-12" is my best hunch at the moment.

[[ Current forecast confidence on a scale of ONE (huh?!) to TEN (supremely confident) is a 6.75 ]]

I'll make sure to update the forecast/conditions Wednesday and especially during the day Thursday.

Thanks for the kind words! This snow season (east of the Rockies, at least) has been depressing to say the least, so we're vastly overdue for a major snowfall.

**Fingers crossed** ;)

Dammit, I'm going to squeal like a little girl.
