Thursday’s weather was outstanding. Our heat and humidity will ramp up Friday afternoon.

Areas of showers and thunderstorms are expected to spread into parts of west-central and northwestern Minnesota Friday afternoon and early Friday evening, then expand northeastward later Friday evening and overnight.

The National Weather Service Storm Prediction Center shows a slight risk of severe weather (shaded yellow) Friday afternoon and Friday evening into the overnight in parts of northwestern Minnesota:

Slight risk means that scattered severe thunderstorms are possible. An isolated severe thunderstorm is possible during that same time period in the darker green shaded areas.

Friday night in NWS lingo ends at 7 a.m. Saturday.

Weekend rain update

Periods of rain and thunderstorms are expected Saturday and Sunday in Minnesota and western Wisconsin. The highest weekend rainfall totals, 1 to 2 inches, are expected from the southern half of Minnesota eastward into Wisconsin. Localized higher amounts are possible.

You can hear updated weather information for Minnesota and western Wisconsin on the Minnesota Public Radio News network, and you can see updated weather info on the MPR News live weather blog.

The Saturday-Saturday night severe weather outlook shows a marginal risk of severe weather in southern Minnesota, the southern portion of the Twin Cities metro area and parts of Wisconsin and northern Iowa:

Rain is really needed in some areas

The timing of the rain is unfortunate for people who have outdoor plans this weekend, but many areas could really use some rain.

The latest U.S. Drought Monitor report shows severe drought across much of the Twin Cities metro area and also in Sibley County and southeastern McLeod County:

The beige area on the map is in moderate drought, and the area that’s shaded yellow is abnormally dry but not currently in drought.

Weekend temps and dew points
