Snow and cold
Snowfall up, temperatures down
During a February that has seen temperatures running far below normal, snowfall in Minot is well above normal. Not even sub-zero temperatures are a guarantee that snow will stay away.
“It is possible to snow when temperatures are really frigid,” said Tyler Kranz, National Weather Service meteorologist in Bismarck. “It certainly can snow if you have enough moisture, even 10 or 20 below may have some snow associated with it.”
Recently Williston bottomed out with a record of minus 43 degrees. Conditions included clear skies, light wind and no snow.
“It was a scenario in which they were experiencing radiational cooling. That’s when temperatures plummet the most. With clear skies you won’t see snow,” said Kranz.
There’s no certainty that it won’t snow when temperatures are extremely cold, just less likely. Minot has had an abundance of very cold weather so far this month but has also easily surpassed average snowfall for the month which is not quite at the halfway point. As of Monday morning the snowfall total at the Minot International Airport for February was 13.2 inches and more snow was falling. The monthly average for February is 5.9 inches.
Minot is not alone in experiencing very cold temperatures and an increase in snowfall.
“In Bismarck we’ve received 7.1 inches in February. That’s 4.6 inches above normal for this point in the month,” said Kranz Monday afternoon. “We are certainly running above normal for snowfall this month. As we all know, the story has been the cold and the snow. We’re not getting any pushes of warm air coming up from the south to give us any relief.”
The Jet Stream has been consistently running well south of North Dakota, which has allowed frigid Arctic air to descend upon the region. According to the Climate Prediction Center the trend is likely to continue for at least the next two weeks.
“We’re kind of stuck in this pattern where we keep getting system after system,” explained Kranz. “Not huge snowstorms with really high snow amounts, but frequent light snow events and these disturbances keep swinging through North Dakota.”
