(Issued 339 AM CDT Sat Sep 23 2023)

Today and Tonight: Challenge remains actual amount of mid level moisture that will remain over south central Wisconsin today. Most models continue to indicate drying in the lower to mid levels today into tonight.
Satellite imagery somewhat indicates otherwise with mid level cloudiness still streaming northward from Illinois and eastern Iowa, although starting to see more breaks in the cloud cover.
Will anticipate this trend through the remaining morning hours.

Fairly certain POPs will be at a bare minimum today, but still cannot rule out isolated showers if moisture remains, especially over the northwest sections of forecast area. Daytime heating could also help. More confident of no precipitation for the forecast area later this afternoon through tonight. Regardless, it will be warm on this first day of fall. Many will enjoy this fall equinox.

Surface flow largely remains southeasterly today into early Sunday as winds could be gusty at times near Lake Michigan.

Sunday through Friday: As mentioned in a previous forecast discussion, Sunday looks to be a battle of moisture gradient across southern Wisconsin. This is due to a northern plains trough of low pressure moving slowly east. There will not be much progress of this system Sunday into Sunday night, but energy and low and mid level moisture will make it back into the western sections of the forecast area. There will also be some difluent flow aloft, leading to widely scattered to scattered showers or thunderstorms beginning Sunday afternoon.
This should translate to at least widely scattered showers moving east Sunday night. All during this time, southern Wisconsin will remain warm with high relative humidity.

Monday will become more under the influence of aforementioned trough passage with cooler temperatures and additional cloud cover. In fact, airmass will be unsettled Monday and Tuesday with scattered showers over most of southern Wisconsin. Additionally, local surface winds should increase Monday night into Tuesday.

Wednesday through Friday is still a little uncertain at this time as mid/upper level pattern transitions. It does look drier again with medium range models building heights aloft over Wisconsin and the Great Lakes. In other words, it should be warming back up over seasonal normals again, especially on Thursday and Friday.

A weak system moves north and leaves southern Wisconsin with gradually clearing skies today. This will result in VFR conditions along all aviation routes. Even less moisture this evening and tonight. Surface winds will remain southeasterly and generally under 15kts through tonight.


(Issued 339 AM CDT Sat Sep 23 2023)

Little higher wind speeds along the lakefront of Lake Michigan today should be monitored for marginal beach hazards. These winds will be from the east to southeast through tonight. Will continue to watch observations, although current thinking is that they will mostly at or just below moderate swim risk. Otherwise, more sunshine later today followed by fair conditions tonight and early Sunday.
