Here's another view of the tornado watch area, with some cities:
The Storm Prediction Center of the National Weather Service also shows an enhanced risk of severe weather this Saturday evening and through the overnight hours for areas just north and northwest of the Twin Cities metro area:
The enhanced risk area includes a small part of northern Anoka county, but most of the Twin Cities metro area is in the SPC slight risk area overnight and Sunday, which means that scattered severe thunderstorms are possible:
Although northern and central Minnesota are expected to see the most thunderstorm activity overnight Saturday night, the Twin Cities metro area and spots in southern Minnesota could see some scattered thunderstorms.
Many spots in Minnesota, including the Twin Cities metro area, will probably see some showers and thunderstorms at times on Sunday and Sunday evening.
There will be some rain-free hours on Sunday too, just have a plan B in case you need to duck indoors at some point.
Here's SPC's severe weather outlook for Sunday and Sunday night:
Updated weather information can be heard on the Minnesota Public Radio Network, and updates are also posted on the MPR News live weather blog.
This will be a good weekend to have your NOAA weather radio or mobile phone nearby for weather warnings that are issued overnight, while you are sleeping.
Travelers will want to be aware of which county they are in, because weather warning headlines typically list the county or counties being warned.
Flooding is possible
Areas that see the heaviest rain this weekend could see flash flooding.
The NWS has flash flood watches from west-central Minnesota into parts of east-central and northeastern Minnesota and northwestern Wisconsin:
Steamy Sunday
Parts of the southern half of Minnesota will have Sunday afternoon highs in the upper 80s to lower 90s:
Dew points will be in the 70s in the hottest areas, so it'll be steamy. An excessive heat warning continues for the Twin Cities metro area until 7 pm Sunday. Heat advisories continue until 7 pm Sunday in south-central and southeastern Minnesota.
Twin Cities metro area highs are expected to be cooler in the coming week, reaching the upper 70s Monday and Tuesday and the lower 80s on Wednesday through Friday.
