Our winter storm is well underway at midday with falling temperatures and all types of precipitation on the radar. We should be left dealing with this winter weather event for much of the day with afternoon wind chills in the single digits. Snow will be ongoing in our northern counties and the freezing line will continue to push its way south through northern Arkansas.
Much of the activity in Arkansas thus far has been rain but that will gradually change over to freezing rain and sleet and eventually snow after lunch. Once the change occurs snow may be heavy for a time before it ends later this evening. There are multiple factors to consider in this forecast, but I think a broad area of 3" to as much as 6" of sleet and snow combined can be expected over much of Arkansas and southern Missouri. If sleet holds on longer amounts could be lower, but if it changes to snow sooner amounts will be higher. There will likely be a rather sharp cut-off to the snow with north extend, and I think Springfield will be on the edge of the band. I'm expecting 1-3" here with lighter amounts to the north.
We'll drop into the teens tonight with highs below freezing on Thursday. After that a warming trend will commence with highs perhaps in the 60s by early next week.
