FARGO — The Fargo-Moorhead area is expected to see an overnight low temperature Friday night, Jan. 10, of about minus 20 degrees, but after that temps are expected to moderate a bit.

That is until Tuesday night, when a second and much more substantial blast of arctic air is forecast to settle over the region, bringing overnight lows in the minus teens and 20s and daytime highs that will likely stay below zero, according to Daniel Robinson, a meteorologist with the National Weather Service in Grand Forks.

Robinson said the cold that will hit the area by midweek could stick around for at least six to 10 days and it's possible some low temps could sink to the minus 30s.

If there's a bright side to the weather outlook, Robinson said no major storm systems are expected in the near term. Though, he said the current weather pattern has included small systems that come through the region and leave behind a dusting or perhaps an inch of snow here and there before disappearing.

Temperatures Sunday and into early next week won't be too bad, with highs expected to be in the teens above zero, Robinson said. But starting around Tuesday night, look out.

Along with the cold, strong winds could create windchill values in the neighborhood of minus 30 degrees. Robinson said once the big cold reaches the region, it could stick around for what remains of January.

"You can get short periods when it warms up a little bit, but don't expect milder temperatures around freezing," Robinson said.

John Wheeler, chief meteorologist for WDAY-TV, said his reading of the forecast leads him to believe that while the cold weather expected next week will be significant, it may not stay consistently cold.

"There will be in-between periods of single digits and teens for highs and probably some nights above zero," Wheeler said.

"Timing of these arctic fronts is difficult, so it may be hard to say which days will be coldest," Wheeler said, adding that the forecast for the coming week also holds the potential for bouts of unsettled weather, including wind and snow.
