KEY MESSAGES

No major impacts expected through the week.

SHORT TERM
(Issued 319 PM CST Sun Dec 10 2023)

Tonight and Monday:

Clouds are starting to thin in SW Wisconsin as models have been showing, but there is uncertainty on the rate of its progression.
High pressure moving in from the west will bring drier air tonight and tomorrow, but there is some moisture trapped beneath an inversion around 3000 ft. Soundings do not show this eroding until late tonight or Monday morning. The back edge of the low stratus is tied to a surface ridge axis over Minnesota. This is projected to move through Wisconsin around sunrise, so we may not see the clouds erode until then. Winds will be light as high pressure moves across the middle Mississippi Valley. Sun is expected on Monday.

LONG TERM
(Issued 319 PM CST Sun Dec 10 2023)

Tuesday through Sunday:

Wisconsin will be under the influence of northwest flow behind a mid level trough. Highs will be in the lower 30s to start this period. A cold front will push through early Tuesday but dry weather is expected. Then high pressure will dominate Wednesday and Thursday.
Temperatures will become a little milder later in this period due to mid level ridging and southwest flow behind the surface high. A shortwave late in the week may bring a chance (20%) for light precipitation, likely rain, but models differ on the timing.
