As winds remain light early on tonight, some patchy fog chances will be in place across central Wisconsin. Clearing skies towards the east and some lighter winds closer to morning will bring fog chances closer to the Fox Valley in the hours before sunrise.
A big change in the upcoming work week forecast. After one more day of temperatures a few degrees above normal on Monday, temperatures for the remainder of the work week will be at or below normal. A big change from the last three weeks of above normal temperatures. Along with the cooler temperatures, a strong storm is expected to move across the Great Lakes region Monday night into Tuesday night. Still a lot of uncertainty in the track and intensity of the storm which will impact the wind forecast across the area. Either way, it will be blustery along with the chances of rain during this period. Unsettled conditions expected at times for the remainder of the week with the chances of showers. Maybe a little late at night or early in the morning on a few days across the north.
A strong low pressure system will move across the Great Lakes region Monday night into Tuesday night. At this time, there is still a lot of uncertainty in the track and strength of the system which will impact the wind forecast across the area. As the system moves east of the state, gusty northerly winds are expected late Monday night into Tuesday evening. The potential impacts from this system include: difficult travel for high profile vehicles and potential power outages across northeast Wisconsin. On Lake Michigan and the Bay of Green Bay, strong northerly winds are expected with gale force gusts possible. Along with the wind, rain is also expected across the area at times during the period.
The Doppler weather radar at NWS Green Bay will be down for a tech upgrade for much of next week beginning Monday, October 23rd. You can find more information about the upgrade by visiting http://www.weather.gov/grb/SLEP2
