Showers and storms are spreading northeast across Iowa this afternoon.
There is still a slight risk of severe storms this evening, but the chance is relatively low. The primary threat would be damaging wind. Most storms this afternoon have not been severe. I don’t anticipate many severe storms if any this evening. There is a Tornado Watch in effect for southwest Iowa through this evening. Those storms will be heavy rain producers for eastern Iowa later tonight.
The low, currently over western Kansas, will track northeast across Iowa tonight with showers/storms. There is a FLASH FLOOD WATCH in effect tonight across a large portion of the Midwest including most of Iowa.
Rain amounts tonight will range from 1-3” in most locations and isolated higher amounts are possible.
The storms will end early Wednesday morning as the wind begins to increase from the northwest. Wind gusts will be in excess of 30 mph at times during the afternoon. High temperatures for the day will be in mainly in the upper 60s during the morning and then slowly fall towards the upper 50s by evening.
Clouds will linger through Thursday with a gusty NW wind. High temperatures will feel more like October Thursday through Saturday…mid 50s to low 60s.
The next chance of rain will be Friday with afternoon highs in the mid 50s. Rain amounts are forecast to be light.
Saturday morning is going to be cold. Temperatures are forecast to reach the upper 30s. There is a chance of patchy frost, but that will depend on how fast the clouds clear Friday night and if the wind diminishes fast enough. We will have a better handle on that Friday afternoon.
The weekend is going to be dry with sunshine, light wind and temperatures in the low-mid 60s…cooler than the normal highs in the upper 70s for this time of year.
