A weak system has already started to make its way into the area this afternoon, but it will take some time for the atmosphere to become saturated before we see any precipitation making it the surface.
With all the dry air in our atmosphere, I think we'll continue to stay dry until around 8 o'clock this evening, but some showers are possible before then.
General accumulations will be minor, but the temperatures across the region will determine what type of precipitation is seen. Areas north of Highway 14 where temperatures will be below freezing tonight could see some light snowfall, whereas those near the border and further into northeast Iowa will just see rain showers. For those of us in the middle, right around I-90, there could be some wintry mixing as temperatures will bounce around the freezing point.
We'll stay dry for Wednesday but another system will be moving in for Thursday morning, bringing light rain to much of the area.
Yet another system is possible for Saturday. We'll continue to track that system as it approaches but with temperatures in the 30's it looks like there could be chances for snow.
