Friday afternoon temperature anomaly forecast — Impressive for early April, and the extent of these colder than average temperatures is quite remarkable for the time of year!

12z GEFS model from April 5, 2018
Temperature Anomaly forecast valid through April 21, 2018. Still no signs of any persistent warmth for northeast Minnesota and northwest Wisconsin through mid April and beyond! The main theme is for continued below average temperatures with perhaps some brief warming mixed in.

There was some light snow in our area today but little to no accumulation since the snow was generally light, and was falling during the daylight hours, and with temperatures around 30 degrees and enough warmth from the April sun coming through the clouds, the snow generally melted on contact.
Reinforcing shot of cold arctic air (early spring edition) is on its way and will be accompanied by scattered snow showers and flurries through Friday morning — Brief heavier snow squalls are possible in parts of our area through Friday morning with a quick half inch to two inches of new snow possible in a few spots.
Lows tonight will range from around zero to the mid teens with highs Friday only in the mid teens to mid 20s which is well below average for April 6 (Average highs on Friday are in the mid 40s!) Although Friday will be very cold, this type of cold has happened before back in 2007 (11 years ago)
The cold temperatures will linger through the weekend, and it looks dry Friday afternoon through Sunday morning.
The chance for snow will increase Sunday, especially during the afternoon/evening hours with the greatest chance for some snow occurring in southern portions of the Northland where a couple inches of snow could accumulate by late Sunday night. Note: Little or no snow is expected the way it looks now for northern Minnesota.
A little warmer next week but still colder than average for the second week of April. Keeping an eye on two systems that could impact the Northland — The time frame is from April 11-14. These systems if they track far enough north could bring a variety of precipitation types to northeast Minnesota and northwest Wisconsin with snow, rain and possibly even some sleet and freezing rain. The system for late next week (Friday-Saturday 13th-14th) could be a strong one per current and recent model data/trends.
Note: Today, April 5 marks the 7th day in a row with a sub-freezing temperature at the Duluth Airport. The last time the Duluth Airport had an above freezing temperature was on March 29! Doesn’t look like will get above freezing at the Airport until Monday, April 9.
