Parts of Montana saw temperatures 28 degrees below average throughout the entire month of February. The Washington Post reported that this is the most extreme deviation in temperatures that has lasted a full month since 1969.
Great Falls, Montana, experienced a record 32 days in a row (ending March 06) with temperatures below freezing. The lowest temperature during this period was minus 32 degrees, recorded March 03.
Montana also set a new all-time record low for the month of March after Elk Park, located southwest of Butte, recorded a temperature of minus 46 degrees.
The National Weather Service described Montana’s recent temperatures as dangerous and “life-threatening.”
“We started off the winter a little slow, then we accelerated,” Missoula National Weather Service Meteorologist Corby Dickerson told Montana Public Radio. “And then this month of February, historic in many ways, has been like we slammed on the gas pedal and said, ‘What spring? What mid-winter thaw?'”
While Montana endured the freezing cold, experts say Alaska experienced record warm temperatures. However this is exactly the pattern we’d expect to see during a Grand Solar Minimum.
Looking at NASA’s own Maunder Minimum Temperature Reconstruction Maps, some regions actually warm during periods of global cooling — the Arctic, North Atlantic and Alaska being the main ones (although ‘warm’ to the Arctic, for example, is still well-below freezing — there’s no melt):
Alaska may have had a relatively snow-less winter, but the Northern Hemisphere as a whole certainly hasn’t. Total Snow Mass for the NH, excluding the mountains, is comfortably sitting well-above the 30 year average:
