Feels like May again; best rain chances are days away

Timing is everything.

After three consecutive days of summery weather in the southern half of Minnesota, May temps have returned for the weekend.

It was 72 degrees around 1 a.m. today at Minneapolis-St. Paul International Airport.  That will go in the books as our Saturday high temp, since daytime highs will be in the 60s in the Twin Cities metro area and much of Minnesota. Some lower 70s are possible in the southeast. A few spots in northeastern Minnesota might only reach the upper 50s.

Sunday highs will be 70 or slightly above 70 in much of Minnesota, with 60s in the far south and along the north shore of Lake Superior:

Twin Cities metro area highs are expected to be in the lower 70s Monday, followed by upper 70s to around 80 Tuesday through Friday.

Rain opportunities

Showers will move through parts of northeastern Minnesota this Saturday morning, but most of Minnesota will have just a chance of a passing shower today and tonight.

Far southeastern Minnesota could see an isolated thunderstorm late this Saturday afternoon or Saturday evening.

On Sunday, there will be a chance of scattered showers in far southern Minnesota.

Our best chance of rain in many parts of Minnesota will be Tuesday night into Wednesday, and Thursday afternoon into Friday.

The National Oceanic and Atmospheric Administration’s Global Forecast System model shows the potential precipitation pattern Tuesday afternoon through Friday:

Cold lake temps

With cold lake temps this time of year, this is a timely reminder from the NWS:

National Safe Boating Week starts today, according to the National Safe Boating Council.

The site has links to stories about people who were saved by life jackets, including two fishermen whose boat capsized on Lake of the Woods last July 31.

The boat eventually drifted into Ontario waters.

The Duluth News Tribune had details of the two anglers' adventure, and this picture of the recovered boat:

Life jackets do indeed save lives.
