Record Cold Over the Next 48 Hours
Question is: How Much Snow Falls?

The second Arctic front in as many days will push across the area early this evening, dropping temperatures from their afternoon highs in the 50s quickly to below freezing. With this front comes another opportunity for snow (yesterday's was a bust), and I have reason to believe that most places to the north of downtown Denver will indeed see accumulating snow.

Basically, the further north in Colorado (and closer to Wyoming) you go, the better chance for accumulating snow. So, Boulder has a better shot at seeing accumulating snow than Denver, and Fort Collins has a better shot than Boulder. Honestly, I have a gut feeling that this system will "over-perform" in that snow totals over the northern quarter of the state (including Boulder) will be higher than the National Weather Service's (NWS) current forecasts.

We'll see record lows in the teens (!!!) tonight (record low for this date at DEN is 25 degrees) along with a 70% of light snow -- possibly mixed with freezing drizzle at times.

"GUT FEELING" SNOWFALL ACCUMULATIONS:
  • Denver: little or no accumulation (NWS predicting under 1")
  • Boulder: 2-3" (NWS predicting under 1")
  • Fort Collins: 3-5" (NWS predicting under 2-4")
**Note: Confidence on scale of 1-10 is only about a 4**

It's possible that a few left over snow showers or even pockets of freezing drizzle may linger into the day tomorrow, but the vast majority of any precipitation that falls will be Friday night. (And, note, I would not be shocked if downtown Denver ends up seeing no flakes at all; they may be just a little too far south this time around.)

We'll see record low temperatures again on Saturday; (the record low high temperature for the date in Denver is 34). I'm thinking it's quite possible temperatures won't make it out of the 20s for highs -- and at best may hit freezing (32). Also, we're highly likely to break records Saturday night, with bitterly cold overnight lows from 15-20 degrees (the record low temperature in Denver is 22).

From Sunday on out, however, we'll see moderating temperatures each day, with highs well into the 60s possible by mid next week. In fact, I think the entire rest of the month of October is likely to feature normal to above-normal temperatures. This cold bout is just a tease!
