(Issued 340 PM CST Tue Dec 5 2023)

- Light rain showers near Kenosha county continue southeastward out of the region.
- Mostly dry weather expected through Friday, with the exception of a chance (30%) for trace amounts of rain / snow on Wednesday.
- Gusty southwest winds Wedensday evening.
- Large uncertainty regarding the position/timing of this weekend's low pressure system passing by, but precipitation is likely at some point Saturday or Sunday.

(Issued 340 PM CST Tue Dec 5 2023)

Tonight and Wednesday:

Lake MI shoreline convergence has created a few isolated rain showers, currently near Racine and Kenosha counties. These will soon clear out to the southeast. Light northwesterly CAA will send tonight's overnight low into the mid 20s to around 30, with lingering clouds preventing it from dropping any further.

The lingering moisture below 850mb lends itself to the possibility (30% chance) of trace amounts of precipitation (sprinkles or flurries) on Wednesday. CAMs corroborate this, with a few areas of weak simulated reflectivity appearing in the daytime hours. Winds turn southwest and become gusty (around 25 mph) Wednesday evening.


(Issued 340 PM CST Tue Dec 5 2023)

Wednesday night through Tuesday:

Gusty southwest winds continue off and on through Friday as a strong low pressure passes through southern Canada. These winds will carry in a warmer airmass, with Thursday's daytime high expected to be in the upper 40s to low 50s, and Friday's in the mid 50s. The 300mb ridge axis passes over Thursday night, while a strong 300mb jet streak over the western CONUS deepens a trough over the Rockies. Split flow develops east of the tip of said trough, and the resultant diffluent flow rapidly develops a low over the southern plains on Friday. The speed and track of this low as it ejects northeastward towards our CWA remains highly uncertain, and depends on the phasing of the upper air pattern.
Ensemble guidance is unsure of whether to place the precipitation in the Saturday or Sunday timeframe, but consensus is growing on modest precipitation rates (whenever it does arrive).


(Issued 340 PM CST Tue Dec 5 2023)

Mostly MVFR ceilings expected tonight, with cloud bases generally between 1500 and 3000 ft and cloud coverage decreasing from OVC to BKN. Winds will be northwest at around 7 kts tonight. Winds turn southwest late Wednesday morning, accelerating to 15 kts with 20 to 25 kt gusts by Wednesday evening. Wednesday's cloud coverage will teeter between SCT and BKN at around the same altitude, with just a chance (30%) for trace amounts of precipitation (sprinkles / flurries).


(Issued 340 PM CST Tue Dec 5 2023)

Low pressure around 29.9 inches will track eastward from Indiana this evening, while high pressure of 30.5 inches overspreads the Great Plains. Light north to northwest winds are expected tonight.
Southwest winds will then develop across the region later Wednesday and linger into the rest of the week as a strong low pressure of 29.2 inches sweeps across the northern Great Lakes region. Gusty southwest winds expected Wednesday evening and night with potential for a few gales. Another period of gusty southwest winds expected Thursday night into Friday though gales are not likely.
