Weather Summary for February 10, 2015
Location:  northeast Minnesota and northwest Wisconsin

A snowy winter day across the Northland.  Low pressure centers of 1012-1014mb were over southeast Manitoba and southwest Minnesota as of 3 PM Today while a strong disturbance moves east through southern Minnesota while another one drops southeast out of southern Manitoba/northeast North Dakota.  This system brought widespread snow to the area Today with bands of heavy snow affecting parts of the area with visibilities dropping to a quarter mile at times.  Highs Today were in the 20s with southeast winds at 5 to 15 mph with a few higher gusts.

Forecast Discussion for northeast Minnesota and northwest Wisconsin

Short Term Forecast - Confidence:  High.

Tonight (February 10)

The low pressure system which is bringing snow to the area Today will be moving east and exiting the Northland later Tonight.  Expect snow early Tonight which will give way to a lighter snowfall from west to east by mid Evening.  Additional flurries/snow showers are possible after Midnight.  Patchy freezing drizzle will also be possible mainly during the Evening.

 Low temperatures Tonight will be in the single digits below to 20s above zero with the coldest temperatures found in far northern Minnesota.  South or southeast winds at 5 to 15 mph will shift to the northwest during the night and will increase to 10-25 mph with higher gusts possible.  Areas of blowing and drifting snow could develop later Tonight.

Note:  Total snowfall accumulations from this event will range from 2-5" in northeast Minnesota and northwest Wisconsin.  Still a low chance that portions of the North Shore pick up around 6" due to possible lake enhancement.

Wednesday and Wednesday Night (February 11)

Low pressure moves over the eastern Great Lakes and eventually into southeastern Ontario during this period as arctic high pressure builds into the northern Plains.  Partly to mostly cloudy skies can be expected Tomorrow and Tomorrow Night.  There could be some snow showers and flurries around the Northland but accumulations shouldn't be more than a dusting or half inch.  Highs on Wednesday will be in the single digits and teens with lows Wednesday Night in the single digits, teens, and 20s below.  Winds will be out of the northwest at 10 to 25 mph.  Note:  Lake effect snow showers could develop along the South Shore of Lake Superior.  On Wednesday, these lake effect snow showers could affect parts of Ashland and Iron Counties, and then Wednesday Night the threat could extend west into portions of Bayfield and Douglas Counties as winds veer a little more NNW.

Extended Forecast - Confidence:  High.

Thursday through Saturday (February 12-14)

A light snowfall event is possible Thursday Night-Friday AM as we see one shot of arctic air move away while the next one moves in during the Friday Night-Saturday time frame.  Temperatures on Thursday will be in the single digits and teens.  Highs on Friday will be in the teens to lower 20s with lows Friday Night in the single digits below to single digits above zero with some teens below possible in northern Minnesota.  Highs on Saturday will be in the single digits below to single digits above zero.

Long Range Forecast - Confidence:  High.

(February 15-20)

Below average temperatures are forecast from the 15th-20th.  A possible light snow event sometime between the 15th-16th but for the most part it's looking relatively quiet around here during the long range.
