Wednesday brings lots of sunshine and seasonable temperatures. More showers and thunderstorms develop Thursday into Friday with locally heavy rainfall possible. 

Warm and gorgeous Wednesday, but more rain coming 

Wednesday will likely be the nicest day for the rest of this week. It will be the only day with totally dry weather and abundant sunshine. Temperatures will range from the mid-80s south to the upper 70s north. 

Clouds will stay at bay most of Wednesday night with lows ranging from the mid-50s north to the mid-60s south.

Unfortunately, the weather doesn’t look fantastic for the Fourth of July holiday. 

Clouds will increase with showers and thunderstorms developing from southwest to east. The wettest weather should remain in southern Minnesota most of the day but much of central Minnesota into western Wisconsin will get storms Thursday night into Friday.

There is once again the potential for locally heavy rainfall. Most of southern Minnesota can expect 1 to 3 inches of rainfall into Friday with locally higher amounts.

There will isolated areas that see more than 3 inches of rainfall. Some models produce as much as 4 to 6 inches of rain in those locally heavier bands. Where that happens could be anywhere in southern Minnesota. 

The National Oceanic and Atmospheric Administration’s North American model paints this heaviest band over the Twin Cities into western Wisconsin, but other models put it elsewhere in southern Minnesota:

There’s a slight risk of excessive rainfall for Thursday into Thursday night:

Due to the afternoon rain and lack of sunshine, instability for severe weather should be fairly low. There’s a marginal risk (level 1 of 5) for severe storms Thursday into Thursday night.

The weekend offers more spotty or isolated chances with less organized activity and low potential at heavy rain. 

It won’t be the hottest nor the coolest Independence Day but we might just make a run for the wettest. 

If we can get more than 2.30 inches of rainfall before midnight Thursday night (which is possible), we’d beat a 124-year-old record for rainfall.
