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!!

The National Weather Service in Duluth has issued a Winter Weather Advisory for portions of Minnesota's Arrowhead and north-central Wisconsin.

In addition, NWS Marquette has issued similar advisories for a large portion of the UP of Michigan.

This map (to the right) shows the locations that can expect to see measurable snowfall, and where the advisories are in place.

Luckily, the snow should mostly melt on contact with roadways and concrete surfaces, but may begin to accumulate on grassy and cold surfaces.

A look at the snow :)

So, I thought I'd grab a picture of the trees and ground turning white. This picture (to the left) was taken around 19:00 and is looking west into my backyard.

Comparing dates.

Last winter, the first snowflakes fell on November 7th; the last snowflakes fell on April 12th. There were 158 days between the two dates.

This winter, the first snowflakes fell on October 27th. If tomorrow is the last date of snowflakes this winter, we will have had 175 days... 17 days longer this year!!!
