Periods of rain and drizzle; wintry mix north
Another gray day. At least the mild weekend temps will shrink the remaining ice on our side streets and driveways.
Extended thaw
Highs in the mid and upper 30s will be common today across Minnesota, with similar high temps on Sunday:
This is an impressive January thaw.

The lowest temperature at Minneapolis-St. Paul International Airport on Friday was 34 degrees.
I expect the Twin Cities temperature to stay above 32 degrees throughout this weekend.
According to the Twin Cities office of the National Weather Service, the longest January period above 32 degrees in Twin Cities weather records was 3 days.
That happened twice; Jan. 21 through Jan. 23, 1909 and Jan. 25 through Jan. 27, 1944.
After this weekend, we will likely have tied the January record of 3 consecutive days above 32 degrees in the Twin Cities, and we might also stay above 32 degrees on Monday.
Fog lingers
Areas of dense fog will linger into early afternoon over much of central and southern Minnesota.
A dense fog advisory is in effect until 1 p.m. for most of central and southern Minnesota, including the southern part of the Twin Cities metro area:

Rain and a mix
Periods of rain and drizzle are expected today and this evening over southern Minnesota, with a wintry mix of rain, light freezing rain, sleet and snow possible over central and northern Minnesota.
There's a chance of scattered drizzle and rain on Sunday.
The National Oceanic and Atmospheric Administration’s North American Mesoscale forecast model shows the potential precipitation pattern this weekend:
Monday looks mainly dry, and we could see peeks of sun by Monday afternoon!
Snow possibilities
This is a rough weekend for snow-lovers.
Our snow cover is likely to shrink.
Here's the snow depth map that was published this week by the Minnesota State Climatology Office:
The green shaded area indicates 4 to 8 inches of snow on the ground. A lot of that snow cover in central and southern Minnesota will shrink dramatically this weekend.
Many spots in northern Minnesota will still have decent snow cover after this warm stretch.
There's a good chance that central and southern Minnesota will see some new snow on Tuesday and Wednesday.
NOAA’s Global Forecast System model shows a low pressure system tracking just to our south next Tuesday and Wednesday:
We could get enough snow to shovel, check back for updates.
