The coldest air of the season arrives this week. A cold front arriving Monday morning will open the flood gates for some very cold Canadian Air where temperatures have slipped below 0º in a few cities.
Temperatures on Monday will fall most of the day, starting in the middle to upper 20s and cooling into the lower 20s and upper teens by midnight. A blustery north wind will return meaning feel like temperatures will stay in the teens throughout Monday. Tuesday will likely be the coldest morning since the end of March. Single digit low temperatures cannot be ruled out.
There is enough moisture in our lower atmosphere for Monday’s cold front to squeeze out some snow showers. Flurries are possible after midnight Monday, but the bulk of any snow that develops will occur between 5am-2pm. There is a better chance for snow in northern Iowa than Minnesota – a dusting in Minnesota and up to ½” in northern Iowa.
The good news is that southerly winds return by Thursday which will warm us above average by next weekend!
