Expect thunderstorms Thursday; severe weather possible

Severe thunderstorm watch west-central and SW Minn. until 3 p.m.

Thunderstorms blossomed over parts of west-central and southwestern Minnesota Thursday morning and are expected to expand eastward in the afternoon and evening.

A severe thunderstorm watch has been posted for west-central Minnesota and parts of southwestern Minnesota until 3 p.m.:

Midday update

In addition to the severe t-storm watch above, the National Weather Service Storm Prediction Center has updated the severe weather outlook for Thursday and Thursday night:

The orange-shaded area indicates an enhanced risk of severe weather, which means that numerous severe thunderstorms are possible. That enhanced risk area now includes the far southern edge of the Twin Cities metro area and much of southern Minnesota this afternoon and tonight. Scattered severe thunderstorms are possible in the yellow-shaded area which covers the central part of the metro area and extends westward and southeastward. An isolated severe thunderstorm is possible in the marginal risk area, which is shaded dark green.

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

Drought update

The latest U.S. Drought Monitor report shows that 96 percent of Minnesota is in drought right now, with slightly more than 8 percent (shaded dark red) in exceptional drought:

The extreme drought area (red) has expanded to include almost all of northeastern Minnesota. Severe drought (shaded-orange) includes most of the seven-county Twin Cities metro area.

I should note that the rainfall cutoff was 7 a.m. Tuesday, so the following rains that fell between 7 a.m. Tuesday and 7 a.m. Wednesday morning are not included in the drought report:

Those rains were heaviest in southern Minnesota, but northern Minnesota had very little rain during that time span.

Parts of Iowa and southern Wisconsin are also in drought:

Weekend thunderstorm chances?

Periods of showers and thunderstorms are a good bet in most of Minnesota and Western Wisconsin Friday and Friday night.

Some forecast models show additional showers and thunderstorms developing on Saturday and lingering into Saturday evening. The National Oceanic and Atmospheric Administration’s North American Mesoscale forecast model shows the potential rain pattern Saturday and Saturday evening:
