Marine Weather and Tide Forecast for Boscobel, WI

DISCUSSION
Issued at 1150 PM CST Sat Nov 7 2026

Today through Tuesday: Dry with Increasing Temperatures

Subtle ridging is forecast to move in over the region over the coming days leading to mainly quiet weather across the Upper Midwest. This pattern will also aid in low level WAA through Tuesday and temperatures each afternoon will be above average for November in the mid to upper 50s to low 60s. Even though a cold front moves across the CWA this morning, the only noticeable change will be the wind turning to out of the northwest. The CAA associated with the front should stay to the north and east over the Great Lakes. The lack of upper level forcing combined with a drier airmass in place should keep conditions dry through Tuesday.

Wednesday and Thursday: Light Rain Potential and a Cool Down.

Upper level troughing, that is currently over the northeastern US, will eventually have another wave that digs south over the eastern US in the middle to end of this next work week.
Increasing mid level moisture out ahead of this feature should be enough to lead to light precipitation potential, if synoptic lift moves over the Upper Mississippi River Valley. Where the better lift provided by the trough will be located varies quite a bit in the latest suite of model guidance, thus the blended NBM PoPs remain low (10-25%) with this forecast cycle. If we do see some precipitation with this system, it is highly likely to be very light and the 90th percentile NBM rainfall values only up to 0.10 inches. If enough cold air can move south at the same time as the light precipitation were to occur, cannot completely rule out some snow mixing in with rain, but that potential is very, very low. Cooler air will eventually move in over the area and temperatures should drop down to near average on Wed/Thu. That trough will quickly depart off to the east by Thursday afternoon and the axis of high pressure moves in behind the trough.

Next Weekend: High Pressure Sets In

Surface high pressure originating out of the Canadian Prairie Provinces is expected to sink south into the Upper Midwest by Friday, dominating much of the weather pattern across the Central CONUS by Saturday. This will keep conditions dry so if we don't see any rain with Wednesday's activity, it will likely be a dry forecast through next Sunday at least. Temperatures will be at their coolest Thursday into Friday with some recovery expected by Saturday into the 50s.
