Monday Morning Update

If you'll recall our keys to accumulating snow in Denver in yesterday's post, moisture and jet induced banding would be the major factors in snowfall totals across the region. We woke up in Denver to only a dusting in many locations, so where's the snow?

Overnight the strongest jet dynamics stalled well north of the city. While most areas in the metro area have only seen a dusting to an inch, places like Fort Collins have already picked up 2 to 3 inches of snow, with nearly 3 inches being report in Boulder as of 7:30am. Snowfall north and west continues this morning.

We do expect the snow shower activity to gradually slide south during the day, but given we are starting from behind expect totals to be only the low end of our Sunday forecast. The Bust Index has remained quite high since we first issued the forecast for Denver, and see little reason to change that now.

It appears as though the biggest negative impact for accumulation from now through Monday evening will be lack of moisture. Even with increased snowfall activity as we head into later in the day Monday, it could very well be hard to see any appreciable accumulation -- the wildcard of course being a heavier snow band or two. We may end up lowering totals in Denver, but for now I think bust low potential is covered quite well with the high BI.

We will continue to monitor throughout the day, and update as necessary. At the very least, please plan for cold temperatures to linger, with off and on light snow through Monday night.
