A pleasant, breezy Sunday; no hot days this week

Recap of Saturday rainfall totals

I’ll take a quick look into Saturday rain totals, then move on to the forecast for the coming week.

The official Saturday rainfall total at Minneapolis-St. Paul International Airport was just nineteen one-hundredths of an inch. I tallied one-quarter of an inch of rain in St. Paul. Radar estimates showed a narrow stripe of 1 to 2 inches in parts of the north metro along and north of I-694, and a stripe of 1 inch or so along and just south of I-494 in the south metro. 

Parts of southeastern Minnesota saw much higher rain totals. Rochester Airport had a Saturday rainfall total of 3.09 inches. Chatfield (in Fillmore County) reported 3.78 inches, and there was a rain tally of 5.10 inches near Grand Meadow in Mower County. A flood warning continues until 1:30 this afternoon in the Spring Valley area of Fillmore County, where the NWS reports portions of Highway 63 are closed due to flooding from the 3 to 5 inches of rain that soaked that area on Saturday.

Here’s the 24-hour (ending at 7 a.m. Sunday) rainfall map from NOAA/NWS:

Notice the red-shaded areas with between 3 and 5 inches of rain in portions of southeastern Minnesota.

Dry in most areas Sunday, then rain returns on Tuesday

There could be a few scattered showers in north-central and northeastern Minnesota and parts of northwestern Wisconsin this Sunday.

One forecast model shows scattered showers in parts of far western Minnesota Monday afternoon and evening.

A more organized area of showers and thunderstorms is on tap for Tuesday and early Tuesday evening. The National Oceanic and Atmospheric Administration’s North American Mesoscale (NAM) forecast model shows the potential rain pattern from 5 a.m. Tuesday to 6 p.m. Tuesday:

The best chance of Tuesday rain in the Twin Cities appears to be during the afternoon hours.
