I know, it’s been too rainy lately. We’ll have additional periods of rain and thunderstorms as we go through Thursday and Thursday evening.  Heavy downpours are expected in some areas, and flash flooding is a possibility.

The National Oceanic and Atmospheric Administration's North American Mesoscale forecast model shows the potential rain pattern Thursday afternoon:

It’ll rain in some areas that look dry in the loop, but the loop illustrates the general rain pattern within the NAM model.  

As always, updated weather information can be heard on the MPR network, and you’ll also see updated weather info on the MPR News live weather blog

Many locations have already seen significant rain totals this week.  A flash flood watch continues until 7 p.m. in the dark-green-shaded areas — which includes the Twin Cities metro area — of the following map:

The areas shaded in light green had flood warnings Thursday morning.

Portions of Minnesota and Wisconsin could also see some severe weather Thursday afternoon and evening.  

The National Weather Service Storm Prediction Center shows a slight risk of severe weather Thursday and Thursday night for parts of south-central and southeastern Minnesota plus southwestern Wisc., with a marginal risk of severe weather extending through portions of southern and central Minnesota, including the Twin Cities metro area, and west-central Wisconsin:

Slight risk means that scattered severe thunderstorms are possible, while marginal risk means that an isolated severe thunderstorm is possible. The Storm Prediction Center will update the severe weather outlook late Thursday morning and also Thursday afternoon and evening.
