May is the 2nd wettest month of the year, on average, across South Dakota and the surrounding states. With the way the weather pattern has been lately, it looks like we'll keep it wet.

May 2008 will begin with a big shot of moisture. Another powerful spring storm is set to strike the region for the end of the work week. As a result, you can expect another round of heavy rain and snow. Snow amounts could be on the higher side over central and western South Dakota. Amounts could reach between 2 to 5 inches. Across much of eastern South Dakota the precip will be mostly in the form of rain with a few imbedded thunderstorms. Some storms cold be on the stronger side too. We could also see a shot at more rain snow mix as this storm moves off to the east.

The strong wind will continue too. The wind will sustain between 15 to 30 as this storm blows through.

Now here's an interesting fact... Sioux Falls' most significant May snowfall fell in 1944 when 3 inches of snow fell on the city. The storm that is moving through could easily dump that amount of snow over much of the area. As of this writing, it appeared as if the heaviest snow would stay off to the north and west of Sioux Falls.

It looks like more rain producing storms are on the way for May. According to the monthly precipitation outlook, from the Climate Prediction Center, much of the upper Midwest is looking at the prospect of above normal moisture.
