RARE JULY FROST AND RECORD COLD HIT MINNESOTA
While chilly summer lows up north aren’t particularly unusual, frost in July is a rare phenomenon, even across the northern stretches of Minnesota.
An Arctic air mass produced low temperatures in the 30s across much of northeast Minnesota on Thursday, reports mprnews.org.
The mercury plunged to 34F (1.1C) at Hibbing — a new record low.
While it fell as cold as 30F (-1.1C) at Brimson yesterday morning — also a new July 8 benchmark.
Below are a few other locales in and around NE Minnesota and NW Wisconsin that logged exceptional July lows on Thursday, data courtesy of National Weather Service Duluth:
AITKIN AIRPORT 34F (1.1C)
SUPERIOR QD NO. 4 31F (-0.6C)
6 WSW BEAVER BAY 32F (0C)
SKIBO RAWS 32F (0C)
These exceptional summer chills are due to an Arctic front which rode unusually-far south on the back of a weak and wavy meridional jet stream flow (a phenomenon that is expected to intensify during times of low solar activity–such as the historically low output the sun has been seeing for the past decade-or-so).
Looking at the GFS 2m Temperature Anomaly run (shown below), these chills are forecast to persist through the weekend and into early next week:
