A Dense Fog Advisory will be in effect until 6PM Thursday for all of our counties, with the exception of a couple in Wisconsin. As of the noon hour here, it is downright thick in some spots, especially northern Iowa. Not much of a surprise – strong south winds transporting warm air over a thick snowpack – a great recipe for dense fog.
Additionally – with temperatures near and sub-freezing still, look out for some patchy freezing fog, and that wind is also blowing loose snow on the roads. Be careful for slick spots with both of those.
Now, on to the latest on the upcoming storm. Tonight we’ll have fog, freezing drizzle and drizzle possible. Thursday’s forecast still holds for murkiness. Fog, drizzle, rain showers. I’m not worried much about the threat of flooding anymore, specifically because our rain amounts should hold to under 0.25″.
Friday is still tricky and will be our transition day back to cold weather. From what it appears, we’ll go from drizzle and rain showers Friday morning to snow showers in the evening, with an icy transition in between. Our temperatures will drop from near 40° in spots to sub-freezing, and highs on Saturday will linger in the single digits, with a howling northwest wind, cold wind chills, and some flurries. I’m still not expecting much snow locally out of the deal. Happy New Year!
If you’re wondering…Thursday and Saturday look to be the better days for travel.
