(Issued 1030 AM CST Thu Dec 7 2023)

High level clouds currently scattered across the CWA as expected.
With plenty of sunshine getting through and light southerly winds today, the warm temperature forecast remains on track.

With the southern Ontario low pressure expected to dominate the wind field on Friday (continuous WAA), by the time the secondary low approaches Illinois Friday night and precipitation across the CWA begins, precipitation should be rain only. Towards the end of the event (Saturday morning), snow may begin to mix in with the rain over the western CWA as westerly CAA finally arrives, but the most common solution on model guidance is a dry slot that terminates precipitation shortly thereafter. As the previous forecast issuance states, the most impactful aspect of this storm is the rainfall, plus some gusty winds (fastest over Lake MI).

Today through Friday:

Quiet weather is expected as a transient upper level ridge moves overhead. Mid/high level clouds will persist across portions of the area today, with a risk of stratus building over the area tonight as south/southwest winds steadily increase low level warm advection.

After a seasonably chilly start to the day, well above average temperatures are expect today through Friday. Highs will be well into the 40s, with a few low 50s today, with widespread upper 40s to mid 50s for Friday.

Friday night through Wednesday:

The 00z suite of ensembles continue exhibit reasonable agreement Friday night and Saturday. The trend and theme of not phasing northern/southern stream energy is by far the more dominate outcome, though there are still some minor differences in the development, location and potential deepening of low pressure. Surface low development with the GEFS is either directly over southern WI or just to the northwest, while with the GEPS and ECMWF ensembles the low track is over southern WI or to the southeast. The upper level pattern evolution and surface low track favor a mainly wet and not white system, though some changeover to light snow is possible as the low exits and cold advection begins. Overall, the biggest impact from the current ensemble variance is on the location of the more substantial swath of rainfall. One quarter to one half inch of rainfall is expected this this system.

There are some indications that another weak area disturbance aloft may move across the area Saturday night, bringing a chance at additional light snow. Moisture looks meager resulting in a dusting of light snow and minimal if any impact.

High pressure builds into the region for the latter half of the weekend into early next week. This results in quiet conditions and temperatures near average for mid December.


(Issued 1030 AM CST Thu Dec 7 2023)

Light south winds expected today. Still expecting scattered high level clouds and VFR conditions today and tonight. There is some potential for a lower stratus deck (MVFR or low-end VFR level) to develop tonight, but confidence is too low to include a prevailing OVC/BKN deck in TAFs at this time, so this will show as SCT around 2500 ft in the next TAF issuance. The 2000 ft AGL winds (which carry the moisture for said clouds) are from the southwest, maxing out at 35 to 45 kts from 03z to 09z tonight. If south surface winds grind to a complete halt tonight, there may be a weak low level wind shear threat from 03z tonight to sunrise Friday.


(Issued 324 AM CST Thu Dec 7 2023)

Southwest winds are gradually declining over Lake Michigan early this morning, and that trend will continue today and tonight.
are after midnight. Low pressure of 29.3 inches will move from the northern Plains into south central Canada tonight into Friday.
This will increase southwest winds, with occasional gusts between 25 and 30 kt. Another area of low pressure will develop over northern Illinois Friday night and move northeast southern Wisconsin on Saturday. Southwest winds will shift to the west Saturday night and to the northwest on Sunday as the low exits to the northeast. Will need to keep an eye on gales for the southern half of Lake Michigan on Saturday.
