Dense fog southeast Minnesota; a chilly rain on Thursday

Temperatures climbed nicely yesterday afternoon, reaching as warm as 42 degrees in Grand Marais along the north shore of Lake Superior. As winds eased later in the day, it was quite comfortable in the sunshine.

This morning’s stillness brings a fog issue in southeast Minnesota, where a dense fog advisory has been posted for Rochester. Visibility was only a quarter mile at 6 a.m. Combine the fog with some refreezing and you have the formula for some travel problems. Drive cautiously this morning. Dense fog advisory in grey continues until 10 a.m.

The mercury tumbled overnight from a very mild 36 degrees in Little Falls in central Minnesota on Monday, to a low of 1 degree this morning.

Some light snow will sweep from west to east across northern Minnesota today. Accumulations are expected to be minor.

It will take a little work for the sunshine to boost the temperatures above thawing in central Minnesota this afternoon, since lows were in the single digits.

Winds should pick up later today and be brisk overnight, holding temperatures in the teens and lower 20s.

As a storm system begins to take shape in the southwest the opportunity for showers and thunderstorms enfolds in south Texas. Paul Huttner is at the AMS conference in Austin, Texas and may have a weather story from there on ATC.



Paul is schedule to speak today on the severe flood event that hammered Duluth in June. This was one of the most extreme weather events of 2012.

While generous precipitation is likely to occur from eastern Texas through Arkansas and into southern Missouri the next three days, the moisture fades as it travels north on Thursday.

Colder air arrives on Friday and we are still watching the potential for accumulating snow, particularly over northeast Minnesota on Friday night into Saturday.

Arctic air remains positioned to settle into the central US this weekend. It looks cold next week.

    Hi Craig,

    I read an article about the flu season and they used the word “nowcast”. I wonder if any weather forecasters have ever tried to predict the spread of the flu with the tools of meterology.

    Hi Craig, are we getting snow Saturday? 🙂

    Heaviest snow should be west and north of the metro on Friday night and Saturday morning. We get the smack of cold air Saturday. Details Wednesday and Thursday.
