Rainy Saturday; chance of a Sunday shower

What a difference one week makes!

We saw sunshine and highs in the upper 70s to lower 80s in much of southern and central Minnesota last Saturday. It’ll be rainy and breezy this Saturday.

Many spots will stay in the 40s during the daylight hours this Saturday, after seeing some lower 50s just after midnight.

Rainy details

Most of Minnesota will have a rainy Saturday and Saturday night. Some spots could also see and hear a thunderstorm.

The National Oceanic and Atmospheric Administration’s North American Mesoscale forecast model shows the potential weekend rainfall pattern:

It looks like northern and central Minnesota could also see some occasional showers on Sunday. The Sunday shower chance in southern Minnesota is mainly during the morning hours.

The color chart to the right of the loop refers to the strength of the radar signal returning to the radar, not to the amount of rain.

The Twin Cities National Weather Service office has this depiction of possible weekend rain totals:

Some spots could see an inch or more of rain this weekend, with most of the rain falling Saturday and Saturday night.

The severe weather risk is not zero in Minnesota Saturday and Saturday night, but it is very small.

The Storm Prediction Center of the NWS shows general thunderstorms in the Minnesota severe weather outlook for Saturday through Saturday night:

Very cool

Our average high this time of year is 71 degrees in the Twin Cities metro area.

Our 51 degree reading at 2 a.m. Saturday could end up being the high temp for the day!

The warmest spots in Minnesota this Saturday will be in the northwest, where some mid to upper 50s are possible.

On Sunday, southern and central Minnesota will see highs in the 50s:

Northern Minnesota will top out in the 40s.

Twin Cities highs should reach the upper 60s Monday, around 60 Tuesday, mid 60s Wednesday and around 70 Thursday.

Coolest May high temps

We typically see at least one very cool day during the month of May.

I checked the Twin Cities weather archives to find our coldest May high temps:

2016   50 degrees

2015   48 degrees

2014   49 degrees

2013   38 degrees

2012   60 degrees

That was a very warm May in 2012, with highs of 80 degrees or warmer on 10 days in the Twin Cities.
