Discussion

Issued at 241 AM CDT Sat Oct 24 2026

There's not a lot to speak on for this weekend as our stretch of dry, mild weather continues. Temperatures early this morning are in the 40s and 50s with mostly clear skies now giving way to a high cloud deck filling in from the west. Some patchy fog is beginning to blossom around parts of SE WI and north-central IN. Patchy coverage is expected to spread into portions of our CWA prior to daybreak, primarily across parts of NW Indiana as well as in Lake Co, IL. While dense fog is not a widespread concern, localized pockets of some denser fog will certainly be possible through early morning, especially in Lake Co, IL. Otherwise, expect another pleasant late October day today with highs forecast in the lower 70s and a fair mix of mid-high clouds and sunshine.

Tomorrow is anticipated to be slightly warmer with lower to middle 70s in the forecast. A weakly-forced cold front will drop through the area from the north late Sunday into Monday. While we're not expecting any rain out of this, it will cool things off slightly for Monday and Tuesday. Monday, given that the front will be pushing north to south across our area into the daytime, is expected to see high temperatures range from the lower and middle 60s in our north to the 70 farther south. 60s and lower 70s will persist through the week with rain-free conditions favored through at least mid-week. A series of waves is then progged to traverse the region and possibly provide us with some rain late in the week and into next weekend.

Doom

Aviation

Issued at 609 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, before directions turn south-southwesterly during the day Sunday. VFR conditions will prevail through the period, though higher level cloud cover can be expected.
