It continues to be the talk of the watering hole. A major cool down will be ushered in beginning Thursday night, which could bring a rain/snow mix to portions of the state.
Say it ain’t snow! This upcoming Friday/Saturday could get interesting!

On Thursday, an area of low pressure will form at the surface over the Plains, and then intensify as it tracks into the northern Great Lakes late this week. Cold air will be drawn southward out of Canada on the backside of this low-pressure system. This will cause temperatures on Friday to be 15 to 25 degrees colder than those on Thursday.
As of right now, there still remains high uncertainty of the track of the low. This will impact when rain will transition to snow, if it does. The current forecast has the track of the low moving across northwest Iowa, which would keep most of the precipitation in the state as rain. It appears that the best chance for rain to transition to snow will be after dark Friday night, as colder air filters in across northern Iowa. Accumulations would be very light to none.
What is not in question will be the strong winds. Winds will be blustery out of the northwest, with gusts of 40-mph or higher. The weekend will then be significantly colder, with temperatures bottoming out in the upper teens and lower 20s on Sunday morning.
