Thanks to everyone who entered our “First Snow” contest. We briefly review the entries, which surprisingly follow closely with Boulder’s climatology of late October.

In the announcement post for this contest, we offered a little insight by providing a few of Boulder’s “first snow” statistics. 87 of you came up with “educated” guesses for the timing and amount of Boulder’s first snow of the 2017-2018 winter season.  The entries are contained in the calendar below:

  • Mean amount: 3.0″ | Median amount: 2.2″
  • The most popular day selected was Wednesday, October 25th. Three people even chose the exact same amount: 2.5″. Is this foreshadow?

March concludes as one of Boulder's snowiest, and an April outlook

SUMMARY OF SCORING:

Those who come closest to the actual date of Boulder’s first MEASURABLE SNOW (defined as snow at or above 0.1″) win! For verification, we’ll go off the official Boulder climate station located at the NIST building in south Boulder.

In the event that multiple entries end-up the same amount of days from the verification date, snowfall amount will be used as the tie-breaker.

QUICK FORECAST:

Alongside the cold temperatures this upcoming weekend, some snow could fall in the Foothills Sunday or Monday, but it looks like any precipitation would be a chilly rain on the Plains. Beyond that, long-range forecast guidance suggests another ridge and warmer temperatures returning by the middle of next week taking us into early October. No prospects for snow just yet!


Prizes and recognition will be awarded in the days following our first dumping of snow, BIG or SMALL. Let’s hope it’s one to remember!
