I mentioned last week that I was watching for our next storm system that could bring rain/snow chances and this is the one. Read on for the details with the rain and wind models included…
A low pressure system will slide across the northern plains Tuesday through Thursday that will bring a risk for strong winds and rain/snow chances. The event will start with rain working into western Iowa Tuesday morning. This area of rain will spread to the east through the day and push east of the state by later Tuesday night. The instability values suggest that even a few rumbles of thunder could be seen generally across the southeast part of the state. In addition to the precipitation, breezy southerly winds will be common across northern Iowa around level 1-2 on my wind intensity scale. By Wednesday the surface low will not have made it too far east which will cause some wrap around scattered rain showers late Wednesday morning through Wednesday evening with gusty west/northwest winds around level 2-4 on my wind scale.
Colder temperatures will start to filter into the system by Thursday with additional wrap around rain/snow showers across the state. Thursday will likely be the day where the strongest gusts will be seen out of the northwest around level 2-5 on the scale. Precipitation should wrap up late Thursday evening/early Friday morning. For the wind, consider this article your wind advisory that would be valid Wednesday through Thursday.
An additional round of gusty winds will follow Friday as the system slowly will move east of the area. Rain amounts will generally be light with the highest totals of 0.5-1.0″ generally scattered across eastern Iowa. Due to this being a multi-day event, further updates may follow if needed.
