From Chief Meteorologist Mike Modrick:
One Last Warm Day!
We have a quiet and warmer night, followed by one last warm day before the next storm develops.
Cooler air and clouds push in Thursday. We're likely to get a rain/snow mix Thursday night into Friday. It's still too early to talk specifics of snowfall with this one, but most computer models are indicating lighter snow for Rapid City and north of I-90, the higher accumulations to the south. We'll continue to track this one closely as it approaches!
