A few stray showers develop along a weak frontal boundary overnight. The National Oceanic and Atmospheric Administration's High-Resolution Rapid Refresh model favors spotty rainfall in Minnesota from the southwest Twin Cities southward toward Rochester.

Severe risk early Wednesday

A cluster of storms will likely blow up in eastern North Dakota in an unstable atmosphere late Tuesday night. NOAA's North American Mesoscale Forecast System 3 km resolution model shows a possible severe bow-echo type system racing east across Minnesota overnight into Wednesday morning.

If this verifies, severe weather is likely in parts of northern and central Minnesota. The system may fade as it approaches the Twin Cities early Wednesday morning.

We'll have to be on our toes for two possible rounds of severe weather. Tuesday night storms are likely in northern and central Minnesota. Wednesday afternoon and evening storms are possible in southern Minnesota.
