But once in a blue moon Minnesota does experience a gently-used tropical depression, the soggy remains of a hurricane or tropical storm. Such will be the case from Tuesday night into Wednesday morning, with the heaviest swath of rainfall expected to stretch from eastern Iowa and far southeastern Minnesota into western Wisconsin, where some 3-5" amounts are expected. Very heavy rain, falling over a relatively short period of time, on ground that is already partially saturated from recent heavy rains, may result in basement, street and stream flooding. For this reason The National Weather Service has issued a Flash Flood Watch from Tuesday afternoon into much of Wednesday.
If you've had flooding issues in the past, you'll to pay attention, especially if you live in Wisconsin.
June is the wettest month of the year, on average, for all of Minnesota, but slugs of tropical moisture this far north are highly unusual. Some communities, especially St. Croix River Valley, far southeastern Minnesota and western Wisconsin, will pick up a month's worth of rain tonight.
No need to water the lawn or garden anytime soon, especially for our friends in Wisconsin!
