Water Runs Downhill

You fight science. Water runs downhill.

All the rain...over 5 inches...in north central Iowa is running down river to central Iowa. The flood warnings are going to stay intact through most of the weekend.

We are most concerned with the Raccoon and Des Moines River basins. Those rivers are going to be above the flood stage through Monday. We will be watching those rising rivers under sunny skies.

Updated River Levels

You can find information in each river in central Iowa. The river gauges connected on the NWS hydrology site. All flood warnings and how each flood stage affects each area is also listed.

Keep it in your favorite weather book marks. It is great information....right here:

Hot June

Yesterday we hit a heat index of 108. The temperature was 92 and the dew point temperature was 78. It is unusual to see this kind of summer heat in June...but this month our temperatures have been at or above normal for 33 straight days. This is the 16th longest heat streak on record....and the 3rd time of such a run of heat during spring to summer.

Afternoon Storms

There is plenty of sunshine right now...but there is also enough humidity in the air and water feeding it from the ground. The instability issue could give us a chance for isolated storms early this afternoon.

There is a very slight chance for strong storms... but we can't call it "all clear" until we get into the late afternoon.

More Storms Over Weekend

It will be great the next couple of days...but more thunderstorms are on the way for the weekend. Storms will be strong again late Saturday into early Sunday.
