Overnight, a wave of lighter snow and sleet moved north over the Ozarks.
At this hour, convective bands (with some lightning and thunder) are organizing over northwest Arkansas and southwest Missouri. This represents heavier precipitation rates and with temperatures in the upper twenties, freezing rain and ice accumulation will continue for a few hours.
There might be sleet in the core of some of the heavier bands, reducing ice accumulations somewhat but overall, expect conditions to worsen through mid-morning, especially north and east of Springfield.
The real question for the day is: how much warming will occur at the surface and where? My belief is that Springfield will see a recovery to near 32 degrees, still icy but more manageable.
The concern all along has been the persistent below freezing situation which will set up for areas of northern Arkansas and perhaps south-central Missouri later this morning and afternoon. An ice storm warning is still in affect for a portion of that area.
