In addition to the snow, eastern Wisconsin heard some thunder during the snow and measured some pretty high winds (summary here).
45 mph at Green Bay, Brown Co. 44 mph at Algoma, Kewaunee Co. 43 mph at Oshkosh, Winnebago Co. 40 mph at Sturgeon Bay, Door Co.
OSNW3 has a great blog post showing the progress of the snowstorm in Oshkosh, WI. The post contains five snow measurements with photos, videos, and radar loops.
Far northern Wisconsin.
I measured 4.0" at my location, and it seems that between 4 and 5 inches fell in my area.
Lake-effect snow enhancement was a possibility with northeast winds off Lake Superior, but it wasn't a huge factor. Perhaps the air was too dry or is simply too much ice.
The Penokee Range in Ashland and Iron counties received the heaviest snow in northern Wisconsin. The higher terrain and the Lake always make this a favorable location.
The highest reports from the NWS Duluth's Wisconsin FA (map): 9.5" Gile, Iron Co. 8.0" Ironwood, Gogebic Co., MI.
Snow depth on Maple Hill.
I like to keep an eye on the snow depth gauge, but the snow seems to drift away from it too often. Based on my other snow depth measurements, the gauge under-represents average depth.Either way, I thought I'd include a picture of the gauge, just as a reference (to the left).
This is a view out across the deck to the northeast (to the right), in the background is the valley and the next set of hills. This is a good example of the farthest view I have from the house here on the hill.
My snow measurements after the storm:
4.0" new snow 0.46" water equivalent 9:1 snow-to-liquid ratio
AT THIS TIME THERE ARE THREE SOURCES OF ARCTIC AIR... A DEEP MASS OVER AND WEST OF HUDSON BAY, A SHALLOW LAYER ASSOCIATED WITH HIGH PRESSURE OVER THE RED RIVER VALLEY AND THE MANITOBA LAKES. BOTH ARE CONTINENTAL ARCTIC IN NATURE.
A THIRD SOURCE OF ARCTIC AIR RESIDES OVER THE THICK, VIRTUALLY UNBROKEN, AND DEEPENING ICE OVER CENTRAL AND WESTERN LAKE SUPERIOR... AN APPARENT MARITIME ARCTIC AIR MASS USUALLY ASSOCIATED WITH ICE CAPS.
THE THICK ICE COVER ACTS LIKE THE BOTTOM OF THOSE FLAT VALLEYS NEAR AND NORTH OF THE IRON RANGE. THE LOW ELEVATION OF THE LAKE CAUSES THE COLD AIR MASS TO COLLECT THERE. THE LAST TM THE LAKE ACTED LIKE A FLOOR OF A DRY VALLEY WAS FEB AND EARLY MAR 2003 WHEN THERE WAS AN EXTENSIVE AND DEEP ICE COVER. So, arctic high pressure brought in cold air behind Thursday's snowstorm. In addition, Lake Superior is acting like a collection point for cold air due to its bowl shape and thick ice coverage. As a feedback, the ice will continue to thicken as long as the cold air is parked over the region.
I'll have a post in a few days on Lake Superior's ice cover.
Cold yesterday and overnight on Maple Hill.
I clipped this screenshot (to the right) from my weather station this morning. It shows graphed temperatures (blue) and wind chill values (purple) beginning at midnight on Thursday morning.
Throughout the snow storm on Thursday, temperatures fell from a high of 20.2 and continued falling until Friday morning when a low of -5 was reached.
Saturday morning was bright, clear, and cold with a low temperature of -11.1 at my location. Inland areas of northern Wisconsin and the UP of Michigan reached down into the minus 20s (see map above).
