Memorial Day Forecast

Memorial Day will start off with plenty of sunshine.  Areas west of the Rock River will have a few more clouds to deal with.  The counties along the Mississippi River (Jo Daviess, Carroll & Whiteside) may contend with a brief shower or two, as remnants from overnight thunderstorms in the Great Plains weaken and move east.


Temperatures will quickly rise into the 80s during the late morning; by afternoon, we could hit 90.  A breezy southwest wind will gust over 25mph ahead of an approaching cold front.  During the afternoon hours (mainly after 1pm), scattered showers and thunderstorms will begin to pop up across eastern Iowa and move east.  These will be scattered in nature, so not everyone will see the rain.  Precipitation amounts will be on the lower end, generally no more than half an inch.


There’s a small risk that thunderstorms could turn severe.  Atmospheric dynamics will allow some storms to contain gusty winds (over 60mph) and sizeable hail.  Frequent cloud to ground lightning is also a threat.  By 11pm, the threat for rain will come to end, as the cold front moves to our east.
