Storm Recap: A misplaced convective snow squall was the wrench in Wednesday’s forecast

February 13, 2020 / BoulderCAST Team

Our low-confidence snowfall forecast ended up turning out okay in most areas on Wednesday. This is despite a huge convective snow squall throwing a wrench into things late in the afternoon. Read on as we discuss what happened and review the totals from the snowfall event, which by the way was our fifth in just the last ten days.

With the conclusion of last night’s quick-hitting snow event, our fourth in just the last eight days, Boulder has now officially eclipsed the typical amount of snow that falls in an entire season, and we’re not even half way through the month of February! We take a look at how this fits into Boulder’s history, what it might tell us about the potential for snow the rest of the winter, and give a quick and dirty forecast for our next chance of snow coming on Wednesday.

Winter Weather Update: Watch out for intermittent heavy snow bands Thursday evening through Friday evening!

Following hot on the heels of the snowstorm earlier this week, another round of winter weather is expected Thursday evening into Friday evening across the Front Range. This one however will be a different beast, defined almost exclusively by a long window of scattered jet-forced heavy snow bands. Extreme uncertainty in the exact location and timing of the banding means potential snowfall amounts are not quite known. We discuss the setup and give our thoughts on what is sure to be a difficult forecast to end to the work-week.
