After lingering morning showers fizzle out we’ll see midday sunshine and more thunderstorms developing later in the afternoon and evening Tuesday. Temperatures will be near 90 this week and continued unsettled patterns.

Stormier setup this week

The center of the upper-level ridge of high pressure that gave us sunshine and dry weather the last several days has shifted east, setting us up on the more unsettled west side of the ridge.

This allows each wave disturbance to touch off some at least spotty showers and thunder. We saw our first cluster of activity early Tuesday. While most saw relatively light rainfall amounts, some areas around Fairmont and Windom in southwestern Minnesota saw up to 1 to 3 inches of rain.

The combination of the shift in our upper-level atmospheric pattern along with higher dew points will all lead to an unsettled pattern with at least spotty or isolated thunder possible each day into the weekend.
