Update on Sunday rain chances and temps

Heaviest rain far south this evening

Will it rain on your outdoor plans today? Let’s take a look.

South-central and southeastern Minnesota and southwestern Wisconsin have the best chance of showers this Sunday morning/early afternoon.

Here’s what happens after that. The National Oceanic and Atmospheric Administration’s North American Mesoscale forecast model shows the potential precipitation pattern from noon Sunday to 11 p.m. Sunday:

The NAM model shows a batch showers spreading across far northern Minnesota this afternoon and evening. A large area of rain with some embedded t-storms is expected to move into southwestern Minnesota toward mid-afternoon then spread across southern Minnesota during the late afternoon and evening hours. Heaviest rain later today and tonight is expected along and south of I-90….some spots there could see over one inch of rain.  Those are the two main rain areas, but scattered showers and an isolated t-storm are possible elsewhere in Minnesota and western Wisconsin Sunday afternoon and evening.

NOAA’s High-Resolution Rapid-Refresh (HRRR) forecast model shows a less expansive area of rain in far northern Minnesota Sunday afternoon and evening:

The Twin Cities metro area could see a late afternoon shower, with a better chance of occasional showers and an isolated thunderstorm Sunday evening and overnight Sunday night.
