Occasional showers, thunderstorms through Wednesday, heating up this coming weekend

1 week ago | kaaltv.com | Randy Brock

While many of us in southern Minnesota have been enjoying sunshine Tuesday, showers and thunderstorms have been moving through parts of north Iowa. An active weather pattern will continue through Wednesday with occasional showers and thunderstorms. On the other hand, there will be plenty of down time between rounds of rain. Thunderstorm activity late Tuesday and again Wednesday will have periods of heavy rain, otherwise the chance of severe storms remains low.

Monday’s almanac – 6/16/25 Randy Brock KAALTV Showers and thunderstorms were widespread from the morning into the afternoon with some in southern Minnesota receiving more than 5″ of rain. A few thunderstorms developed again in the evening but were much less widespread. Here’s a look at the climate stats for Monday, June 16th....
Active pattern through much of this week, although severe threat is low

1 week ago | kaaltv.com | Randy Brock

Showers and thunderstorms will remain common across southern Minnesota and north Iowa through the rest of this week. The days with the highest potential of rain are Tuesday and Wednesday. If we see thunderstorms develop Thursday and Friday, they look to remain more isolated. While we continue with an active weather pattern, we’re not under the gun for much in the way of severe thunderstorm potential. The chance is not zero, and there will be a few thunderstorms, but widespread severe is not likely.
ALERT DAY for strong to potentially severe storms Monday evening

1 week ago | kaaltv.com | Randy Brock

We have already had one round of storms with heavy rain Monday morning, and redevelopment of thunderstorms is likely Monday evening. A line of thunderstorms will likely develop to our west and northwest around 6-7pm Monday and move through southeast Minnesota and parts of north Iowa through the evening hours. A few storms may be strong to severe with the possibility of damaging hail and wind.

Friday’s almanac – 6/13/25 Randy Brock KAALTV Some parts of southern Minnesota and north Iowa received heavy rain into early Friday morning. Temperatures stayed cool along and north of Highway 14 while they hit the upper 70s to lower 80s south of it. Here’s a look at the climate stats for Friday, June 13th....
A warm Father's Day weekend ahead with the occasional thunderstorm

It’s very unlikely that we’ll get through the weekend without some good, heavy downpours. However, there will be more time without rain this weekend than with it. Temperatures suffered a bit in parts of southern Minnesota thanks to a stubborn stationary front, but that’s looking to change this weekend with highs getting a boost into the upper 70s to lower 80s for most. That front will still provide the focus for a few thunderstorms, especially from Saturday evening into Sunday morning.
Warm weekend with occasional thunderstorms, active pattern continues next week

While the majority of Friday has been quiet, a front remains draped across southern Minnesota with temperatures in the 60s on the north side and upper 70s to lower 80s on the southern side of it. This front is also the focus for some thunderstorms Friday evening. Those will begin to fade quickly Friday night into early Saturday morning. Saturday will be much like Friday although most locations across southern Minnesota will be warmer with highs around 80 and dew points climbing into the mid-60s.
A few thunderstorms Friday through the weekend, but it won't be a washout

Tis the season for more common, rogue thunderstorms to develop, and that’s just what we’ll see Friday through the weekend. With that said, it’s not going to be raining the majority of the time from Friday through Sunday. There will be enough instability in the atmosphere and a few boundaries (fronts, where winds converge) that are going to provide the focus for a few showers and thunderstorms. Our severe risk is very low Friday, same with Saturday and Sunday.
A few showers and thunderstorms into the weekend, but the majority of time will be without rain

The area of concern for consistent showers and thunderstorms has shifted to our north, into central Minnesota and Wisconsin. We will still see the occasional, isolated shower or thunderstorm going into the weekend in southeast Minnesota and north Iowa. An isolated strong storm or two may join the mix with small hail and heavy rain, but severe weather is not likely. We can expect a similar day Friday in comparison to the weather we’ve had through Thursday.
Showers, thunderstorms continue Wednesday night through Friday

As of late Wednesday evening, the severe weather threat has faded away for southern Minnesota and north Iowa. However, there will still be occasional thunderstorms across the area from Wednesday night through Thursday. The focus for organized showers and thunderstorms looks to shift a bit farther to our north Friday, but there may still be a few lingering across the area to wrap up the week. By the end of the week, we should have at least a pocket or two with rainfall totals around 1-2″.
