Widespread rain will be likely this weekend, and it looks to be heavy which is unusual for December. Highs this weekend will keep the rain from transitioning over to snow, which is saddening for some of you.
Rain will begin to lift north throughout the day Saturday. Some light rain/drizzle may be possible late this evening ahead of the main moisture. Rain will continue overnight Saturday and into the day Sunday. As the low slides off to the northeast across the state, cooler temperatures will begin to work into the state. There may be enough precipitation still around in northwest Iowa which would allow some of the rain to transition over to a wintry mix.
So far snowfall accumulations will be confined to northwest Iowa and to the northwest of the state. As of now, any accumulations in Iowa appear to be around an inch or less. Our temperatures will be just too warm for it to snow. However, if cooler temperatures get pulled into the state earlier like some of the models have been trying to do today, then it might be possible for some more snow. For now, not going with this idea, but it does make for a difficult forecast. Many of you have been seeing model outputs floating around on social media showing anywhere from 1″ to 24″. Just try to ignore those since the models have been all over the place with this storm system.
Eventually the system will pull out of the state by Monday leaving behind much more seasonal temperatures. If anything is to change over the next 24 to 48 hours, check back here for the latest updates as we will be sure to give you the very latest information.
