Here we go again.

Another round of thunderstorms is expected to develop later Sunday afternoon and night over a large part of southern Minnesota, according to KSTP's Chief Meteorologist Dave Dahl.

The Twin Cities are on the northern edge of where the heaviest rain could fall. Dave says even with moderate rainfall, flash flooding could be an issue.

This will more than likely impact the river crests. The St. Croix, Mississippi and Minnesota rivers were all expected to crest later this week.

If you're in an area that has seen flooding already this spring and early summer, please be especially alert Sunday evening, Dave says. Information on sandbags and other resources can be found your city's website.

Slow moving storms are part of the problem this time around. The winds aloft are not favorable for a widespread severe event, but they are conducive to excessive rainfall.

Heat and humidity aren't going to be in short supply either. Temperatures on Sunday and much of this week are still going to be in the 80s.

The Outlook

Even though we're expected to dry out a little on Monday and Tuesday, another round of thunderstorms is expected to move in Tuesday night and Wednesday, Dave says.

Unfortunately, an even larger wave in the jet stream spells even more trouble late in the week and into next weekend.

This wet pattern might stick around into the first part of July, Dave says. June is on track to go down as the wettest on record.
