Storm Center Update - Saturday PM

Severe Thunderstorms Warnings and rainfall are both picking up speed late this afternoon.  As anticipated the severe storms are West River but should begin moving east later this evening.  In the east, we’re tracking a line of showers from Huron to Sioux Falls.  There isn’t that much threat of high winds or hail with THIS area of rain, however skies are very dark and locally heavy rains are possible.  There’s a very impressive outflow boundary over the Coteau and south of Aberdeen.  I wouldn’t be surprised at all if storms form near the Clark and Watertown areas as a result of this.
Later this evening we’ll still be tracking thunderstorms in western SD.  These could produce high winds and large hail.  Generally speaking, these will move ESE, but some of these storms are moving off to the NE and splitting into pieces. 
The rain near Sioux Falls will be sluggish in clearing the area but we should see a break in the action, at least for awhile.  We know there’s a LOT going on outdoors this evening, whether concerts or shows or sports.  We’ll be constantly updating Facebook and the website but we’d advise bringing the StormTracker app.  You can check the radar and give yourself a few minutes to grab a jacket, at the very least.  More rain is possible later, before and after midnight near Sioux Falls.  Rain could take its time finally clearing the region late tonight but much of tomorrow morning actually looks pretty nice.  Parts of KELOLAND will likely see rain tomorrow but the severe weather threat is mainly in North Dakota.  Leftover showers will remain for Monday, at least early in the day, for those east of the Missouri.  Tuesday looks to be noticeably warmer in the east, with more sunshine.  There are chances of storms in the west.  After that, there’s a chance of rain every other day.  We’ll still have nice periods to get outside, even on the days it rains.
