#Snowpack news: Good snowfall forecast

From The Longmont Times-Call (Charlie Brennan):

Coming in just under the wire, Boulder County could see its first measurable snow for the month of March on its last day. But maybe not.

March is typically the snowiest month of the year in the Boulder area, but snow has been a no-show this month, which has been far drier and more mild than average.

It’s going to change as the final hours of the month tick down, with up to 8 inches of snow possible in the area through Saturday.

A Pacific storm system already affecting the Great Basin and heading into the Four Corners region will be making its presence felt along the Front Range early Friday morning with a chance of showers developing after midnight.

The chance of rain increases to 70 percent during the day Friday, with the day’s high topping out around 44 degrees.

After rush hour Friday evening, the rain should be mixed with snow, and changing entirely to snow by the early morning hours, with Friday’s overnight low to be 30 degrees.

In his weather blog, Boulder meteorologist Matt Kelsch said “the changeover to snow in lower elevations is likely to occur around the time of the most steady and heavy precipitation late Friday afternoon and evening. A small shift by a few hours can have a big impact on snow amounts.”

All of eastern Colorado should get significant precipitation, Kelsch said, although a potential shift in the storm’s heaviest impact toward the south of Colorado Springs — and the timing of such a shift — could affect the outcome, in terms of how much falls and where.

The snow will make a bigger impact above 7,500 feet, where 10 to 20 inches could fall, with some portions of the Front Range seeing more than 2 feet.

In Boulder County, new snow accumulation of 4 to 8 wet and slushy inches is possible, but it is uncertain how much of that will be credited to March, and how much will fall after record keepers have flipped the calendar to April Fools’ Day.

That, Kelsch said, is because for official record-keeping purposes, the books will be closed on March at 6 p.m. Friday. Snow that falls at 6:01 p.m. Friday or later will be credited to April’s totals…

It is rare, but not unheard of, for Boulder to see no measurable snow in March. Kelsch said Boulder was shut out for measurable March snow most recently in 2012. With only a trace amount of rain that month, it remains Boulder’s most arid March on record.
