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.

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.

    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? :)
