Severe Storms Tuesday Night

Severe Wx Risk for web
We are tracking storms forecast to move through eastern Iowa tonight…mainly after 9 or 10 PM. An isolated shower or storm is possible before this time, but the more widespread storms will be after and through the overnight. Heavy rain, damaging wind and large hail are the primary threats with the storms. The storms are forecast to end between 4-6 AM Wednesday.

Most of Wednesday is dry with a slight chance of an afternoon shower/storm. High temperatures remain in the mid-upper 80s and humid. We are tracking another round for storm possible for late Wednesday night into Thursday morning. Again the main threat of any of the storms would be heavy rain, damaging winds and large hail.

Friday through Sunday is dry, a bit cooler and less humid before the heat and humidity with storm chances return early next week.

Storms Tonight with Heavy Rain and Hail

A warm front, southwest of Iowa early this afternoon, is forecast to move northeast across the state.

As it does, rain and storms will develop later this evening. The storms are expected to develop around 10 or 11 pm and become widespread in just a couple of hours. The initial storms could produce large hail and heavy rain. Then the threat turns to more of a flooding rain situation. Widespread 1-2″ of rain is expected with isolated higher amounts to near 5″. This is the reason why a Flash Flood Watch is in effect tonight.

Flash Flood Watch

Flash flood guidance shows the ground could only handle a little more thanĀ 2″ of rain in 3 hours. Some places might see more than that.

Here is the rain forecast for Tuesday evening to Wednesday evening. Most of this rain will fall tonight.

The storms will be widespread overnight and eventually ending between 7-9 AM Wednesday.

Hot and Humid with a Few Storms

A Severe Thunderstorm Watch is in effect for the counties along the Iowa/Minnesota border until 9 PM.

The primary threat would be large hail and damaging wind with any of the storms. The timing of the storms would arrive in this area between7-9PM.

1

Once the storms move south into Iowa, they are forecast to weaken quickly and in some cases fall apart completely. Any rain/storm chance would occur before midnight tonight. It remains warm and humid overnight.

Saturday is almost a repeat of Friday when it comes to the heat and humidity. The sky will be mostly sunny most of the day. Between 3-7 PM there is slight chance for a few storms to develop. At this point a severe storm is possible if they develop. The storm chance lingers into the overnight, but in an isolated fashion.

Sunday is still humid and slightly cooler by about 5-8 degrees. A mix of sun and clouds are expected.

The weather pattern becomes a bit more active next week with a chance of storms each day. Temperatures cool into the low -mid 80s, but the humidity level remains high.
