Today we will have a mix of sun and clouds with temperatures in the upper 30’s to near 40. However, the clouds will be building back into the state by this evening, ahead of our next system. This will bring the potential for rain, and potentially freezing rain/drizzle across northern Iowa.
Rain will begin to enter into northwest Iowa during the morning hours Sunday. Timing on this looks to be after 8am. Some of this may freeze on contact forming a light glazing on some surfaces so if you will be heading out tomorrow morning, make sure to check the latest road conditions.
Rain will the continue off to the east and will be entering into central Iowa after the noon hour Sunday. Once again, light freezing rain/drizzle may be possible later on in the afternoon to early evening hours as the surface temperatures fall to freezing.
This line of rain will continue to off to the east and will be in eastern Iowa Sunday evening into the early morning hours on Monday. Rain will then pull out of the state by 7am Monday morning. The latest WRF, or high-res model is trying to to show some minor snow/sleet accumulations with this system. Some minor accumulations may be possible, however, they will be very light to almost none, with the best chance for snow across northern Iowa. Temperatures will be near freezing on Sunday, so rain may change over to a freezing rain or snow at times, and then change back to rain. If you will be heading out on Sunday, plan ahead and check the very latest road conditions at 511ia.org. After this system pulls out of the state Monday, high pressure builds into the state on Tuesday and the warming trend will begin into next weekend. We will have the latest forecast on the above seasonal temperatures that we will be expecting next week later on here at iowachase.com. For now, here is a preview below.
