Shower chance for Memorial Day and Tuesday
A low pressure system is located just north of Lake Superior this Memorial Day.
The low will begin to move slowly away from us on Tuesday, but Minnesota will have cool and breezy weather right through Tuesday.
We'll see occasional scattered showers this Memorial Day, and some scattered to isolated showers are possible on Tuesday.
North-central and northeastern Minnesota will probably see the most minutes of rain both days.

An isolated afternoon or evening thunderstorm will also be possible in southern and central Minnesota.
The National Oceanic and Atmospheric Administration's North American Mesoscale forecast model shows the potential rain pattern Monday through Tuesday:
Rain will fall in some areas that aren't looking showery in the loop, but the general rainfall pattern should hold.
The color chart to the right of the loop refers to the strength of the radar signal that returns to the radar, not to the amount of rainfall.
Cool temps
Minnesota will see chilly Memorial Day high temps; at least 10 degrees below normal in most locations.
Afternoon highs will be in the 50s in most of northern and central Minnesota, with some lower 60s in the south.
Similar highs are expected on Tuesday:
We'll see a nice temperature rebound on Wednesday, with many spots in the upper 60s to lower 70s:
The Twin Cities metro area could see highs in the upper 70s on Thursday and Friday, followed by highs around 70 next weekend.
Cool May
Through May 28, the preliminary climate report from the National Weather Service shows that the Twin Cities average monthly temperature is running three-tenths of a degree below normal this May:
That's significant, because we don't see any really warm days before the end of May.
Our streak of consecutive warmer than normal months in the Twin Cities metro area will end at 20 months.
The last time that we had a cooler than normal month in the Twin Cities was August of 2015!
