We’re off to another foggy start on this Wednesday morning. A dense fog advisory remains in effect for Buffalo, Clark, Jackson, Taylor and Trempealeau counties through 9 am Wednesday. Visibility less than 1/4 mile will be possible at times.
Otherwise, the fog will lift and visibility will improve quickly after Wednesday morning’s commute. But, extensive cloud cover and light mist/drizzle may persist through the afternoon.
Temperatures will stay in the mid to upper 30’s and eventually break into the low 40’s ahead of our next weather maker.
Two low pressure systems are moving towards the Chippewa Valley. One is sweeping across the Dakotas’ and is expected to bring heavy snow to northern Minnesota. We will not see a direct impact from that round of weather.
Instead, that low pressure center will morph into another, fast moving low pressure system out of the southwest. Together, they will produce widespread rainfall across Wisconsin overnight Wednesday into Thursday morning.
The rain will start sometime after 8 pm and rainfall rates will be moderate to heavy at times with 1/2” to 1” of rain accumulation by early Thursday morning.
Then, colder temperatures will funnel in turning the northwestern edge of the rain to snow. Temperatures will consistently fall through the afternoon Thursday and northwestern counties like Barron, Polk, Rusk, and St. Croix could see upwards of an inch of snow by midday Thursday.
Those cold temperatures may fall into the teens for Friday morning but temperatures will rebound for gun deer camp on Saturday.
You’ll likely start hearing chatter on social media about a Thanksgiving snow storm. The Stormtracker 18 Weather Team is monitoring the trends of a system that may impact travel across the upper Midwest Tuesday through Thursday next week. But we want to remind you that the path of the system, how much rain or snow could fall, and the timing will likely change before that event hits. We recommend having a backup travel plan just in case and stay tuned for updates.
