With a steamy, stormy Father’s Day looming, the National Weather Service is keeping in place an excessive heat warning through Sunday evening.

Also, Saturday night storms were bringing flash flood warnings until early Sunday in central Minnesota and northwestern Wisconsin. A severe thunderstorm watch was in effect for parts of Minnesota, North Dakota and Wisconsin until 5 a.m.

Rain, some of it considered torrential, was falling and expected to continue for a few hours late Saturday into Sunday, the National Weather Service in Duluth warned on Twitter.

For the metro, Sunday will bring a high of 93, but with high humidity, the heat index value will make it feel more like 102, the Weather Service in the Twin Cities said. Father’s Day picnics and basements alike may spring leaks in the late afternoon, when storms bearing heavy rain are likely to crop up, lingering through the night.

Monday, too, will bring a chance of showers, but it will be cooler, with a high near 77.

Steadier sunshine and highs in the upper 70s and lower 80s will be back Tuesday, Wednesday and Thursday, the Weather Service said. Later in the week, rain may return.

As always, the weather at hand brings pluses and minuses. With hot, humid air over most of the state, the countryside is green as Ireland. But if you want to get out into it, it’s best to take ice water and lots of bug spray.

The excessive heat warning designation should serve as a reminder that conditions can be downright dangerous for those being overactive in the great outdoors. A list of cooling centers for Hennepin and Ramsey County residents without air conditioning can be found on the Weather Service’s website.

The warning is in place in the metro area, while a less dire heat advisory is in effects for several counties surrounding and south of the Twin Cities.
