While rain has been a little more timely and plentiful in the past couple of weeks, we could always use some more and it looks like we stand a chance of picking up some decent rainfall totals in the next day or two as two storm systems will be affecting the region. The first system is moving through the Upper Midwest today, spreading clouds and rain across the local area through today and at least the first part of tonight. There will be a few thunderstorms possible this afternoon and evening with a few strong storms possibly producing strong winds and some hail. The best chance for that will be to our west, however, while more benign activity is expected for us. The second storm system looks a little weaker and comes from northwest Ontario tomorrow. We’ll have some light showers and a couple of thunderstorms with occasional sunshine Thursday, especially in the midday and early afternoon. The rainfall deficit for the year going back to spring is almost two inches for Rochester and around seven inches in northern Iowa so we’re all still hoping for a good soaking shower this week. High pressure from Canada will follow that second system, bringing dry, cool weather to the Upper Mississippi Valley Friday and Saturday as high temperatures will be in the low to mid 70s.

Most of our area can expect a quarter to half an inch of rain today through early tomorrow, but some spots will pick up an inch or more under the heavier thundershowers. Parts of north Iowa are still several inches below normal for the past year, so this is good news.

There is a Slight Risk for severe weather along the Missouri Valley to our west and locations around Algona and Clarion, Iowa may see a couple of stronger storms as the heart of Wednesday's storm system pushes through the area. The rest of us can expect garden variety thunderstorms with light to moderate rainfall.
