Increasing storm threat this weekend/early next week

There is growing concern for potentially strong to severe thunderstorms this weekend and early next week across the Plains and Midwest.  The SPC (Storm Prediction Center) has had the Plains highlighted for a risk of severe storms nearly all week with the threat extending further east Sunday and Monday.  A strong and deepening low pressure system will lift north through the central and northern Plains.  Unlike with the weather this past week moisture from the Gulf will be wide open streaming in to the mid-Mississippi River Valley.  A strong cold front combined with a deepening upper level trough will move out of the Rockies early this weekend.  Areas from central Nebraska through South Dakota hold the greatest threat for severe weather Saturday afternoon.  The weather locally may end up mostly dry during the day.  As the system slowly progresses east so will the storm threat putting places from Oklahoma, Kansas, Missouri, Iowa and western Illinois in line for potentially severe storms Sunday and Monday.

The devil is in the details, though.  Storms west of here will likely influence the weather here locally.  However, it's important not to let your guard down despite a very slow start to the severe weather season.  Updates will continue right here as we get closer to the weekend.

Along with the storm threat will also come the threat for heavy rain Sunday night through Wednesday.  This system will be slow to leave through the week with numerous rounds of storms possible.
