Discussion

Issued at 150 PM CDT Fri Oct 23 2026

Tonight through Sunday:

As of this writing, what had been a bank of extensive fog and very low clouds across Chicago's far northern suburbs this morning has finally contracted to a remaining patch near Winthrop Harbor, IL. With lake enhanced moisture evident in the Waukegan and southeast WI dew point obs, wouldn't be surprised if patchy fog sneaks back into northeastern Lake County this evening from continued light to moderate southeasterly boundary layer flow.

Another calm night is in store tonight, with the main change happening aloft in terms of strengthening southerly flow just above the nocturnal inversion. Over the southeast half or third of the area (I-88 corridor in interior Chicago metro and points southeast), flow aloft should be sufficiently weak to enable patchy shallow ground fog development. Can't completely rule out very localized dense fog, but the setup isn't nearly as favorable as this (Friday) morning. High clouds will filter in from the northwest overnight into Saturday morning, keeping overnight lows a bit milder across interior northern Illinois in particular.

On Saturday, high temperatures will likely be close to a carbon copy of today (Friday), in the lower to mid 70s. Illinois side lake cooling will be confined to the immediate shoreline during the afternoon as southerly winds back to southeast with lake influence. Following a calm and cool (relative to Saturday afternoon's warmth) Saturday night, Sunday will likely be the warmest day of this stretch unless mid and high cloud cover limits high temps a bit.

Sunday Night through Friday:

Aviation

Issued at 1209 AM CDT Sat Oct 24 2026

There are no significant aviation weather concerns anticipated through the period.

Surface high pressure will center over New England today into tonight as a cold front shifts eastward from the PLains into the Upper Midwest. Overall, this will result in light south- southeasterly surface winds across the terminal airspace today and tonight. VFR conditions will prevail through the period, though higher level cloud cover can be expected.
