Snowfall graphic from Chanhassen NWS from Saturday and Saturday night.
A large swath of Minnesota missed out on the Saturday snowfall. Lakes will ice over and the ice will thicken at different rates depending on the micro-climate. Snow covered lakes/ponds are likely to be insulated somewhat in southeast Minnesota and ice may be slow to thicken despite the cold temperatures.
Before venturing out on regional lakes please check for ice thickness with the DNR. Here's a link on ice safety.
Once again the moisture deprived region of from Redwood Falls to Ortonville missed out on Saturday's precipitation.
The snow to water ratio varied from the Twin Cities to Winona. Rochester received 3.4 inches of snow with 0.34 inches of liquid. In Chanhassen, the snowfall was 3.2 inches with liquid precipitation 0.16 inches. That difference in moisture content identifies the challenge of predicting snow amounts based on expected liquid precipitation.
A cold week is in store for the Great Lakes region. I'll avoid using the term "warm-up", but a moderation is expected on the weekend.
In other weather news, more heavy rain is on tap from Indiana into Kentucky and Ohio. Louisville, Kentucky has accumulated nearly 64 inches of moisture in 2011, 22 inches above normal for the year.
Here's a snap shot of the radar from early this morning.
A nice visible satellite image from around 3PM shows the clearing line through central Minnesota. As clouds break up overnight and winds drop off to less than five miles an hour, it we create ideal conditions for temperatures to chill down to at or below zero over the fresh snow cover.
The GFS forecast model paints the early Tuesday morning temperatures below zero in south central Minnesota. The pressure pattern and winds indicate the overall stillness in the chilly air mass.
Notice the cold temperatures in Colorado as well. Check out the computer model detailed resolution of the very cold mountain temperatures.
Minnesota will see a moderation in temperatures on Wednesday as relatively milder moves across the snow free landscape of western Minnesota. Fargo, North Dakota and Sioux Falls, South Dakota have accumulated less than an inch of snow so far this season. Another shot of cold air arrives for Thursday and Friday.
Temperatures may reach the thawing point Saturday and Sunday afternoon.
This morning I was tracking the very heavy rains in Indiana and Kentucky. The Louisville, Kentucky NWS Office has recently posted a story that the Derby City has set a new annual precipitation record. And at mid afternoon the rain continued to fall.
