As a big March snowstorm approaches Colorado, many people on the Front Range should expect to see snow totals in the range of 20 to 40 inches. That being said, multiple forecasters have mentioned possible totals above seven feet in some smaller pockets of the state.

Included in OpenSnow's daily report, the American Global Forecast System mapping shows that a small pocket of Colorado could get between 60 and 90 inches of snow from Thursday night through Monday. Forecaster Joel Gratz calls this an outlier that's unlikely, but also acknowledges that outlier storms can result in outlier totals. (See an up-to-date daily snow report from OpenSnow here).
The pocket of Colorado that could get hit with this more intense snowfall, based on the American GFS report, includes the area surrounding Eldora Mountain Resort in Boulder County, stretching north to the Wyoming state line.
Forecast mapping from KDVR also shows a possibility of similar totals, with 91 inches in the forecast for Estes Park throughout the entirety of the storm.
According to most forecast models, the heaviest widespread snow during the weekend storm is expected to fall along the I-25 corridor from Colorado Springs to Fort Collins, with the highest accumulation totals in the mountains directly west of this interstate. The portion of Colorado west of the Continental Divide is expected to get notable snow, but no where near the multiple feet that are expected on the Front Range.
The National Weather Service has posted a 'hazardous weather outlook' that warns of between one to three feet of snow along the urban corridor, with the potential for more in the northern foothills. They expect the storm to cause travel in impacted areas to become 'nearly impossible'.

The Colorado Department of Transportation has already warned drivers against traveling around much of Colorado this weekend, including sections of I-25 and I-70. Drivers that are traveling have been instructed to get to their destination before the storm starts to ramp up Friday night into Saturday morning.
Winter weather of this nature poses many hazards. It's crucial that Coloradans stay up-to-date with the most current forecast. Find information from the National Weather Service on their website and check out the OpenSnow.com daily report for more info.
