29. As winds turned northeast on Saturday, the big Lake kept the lakeshore counties cold. Rain and snow moved in on Sunday and will continue through Monday.
I grabbed this map (to the right) from GRlevel3, which shows temperatures and wind barbs at 18:15 (6.15p) on Saturday evening.
On top of the map I drew in 10-degree temperature contours, with labels.
The counties bordering Lake Superior stayed in the 30's and 40's most of the day, while much further inland the temperatures were in the lower 70's. Quite a contrast!!
While the Lake is now ice-free (except for many stray icebergs), the water is only a few degrees above freezing. (The current map of water temperatures can be found here). This cold water will occasionally modify my weather throughout May, June, and sometimes even into July.
A low pressure system brings needed moisture to the region.
Fire danger began increasing last week from dry weather and a slow green-up this spring. Current statewide fire danger can be found (here) from WDNR.
Luckily, rain showers will blanket the region today and tomorrow, soaking the ground and reducing the fire danger.
I captured a radar image of Minnesota and Wisconsin (to the right) from Intellicast.com at 16:30. The radar image shows the possibility of snow around the western tip of Lake Superior, with rain showers elsewhere.
As I type this at 18:25, the rain today (0.27") has turned to moderate snow; the snow is starting to turn the ground white (trace). The temperature has been steady today in the mid-30's and is beginning to edge down toward freezing, I have 33.2 degrees currently.
Some accumulating snow across the Northwoods tonight!!
