Forecaster's discussionIssued 10/28/2026, 1:31 AM EDT

Key messages

- Warm and dry conditions persist through tomorrow with highs generally in the low 70s and lows in the low 50s.

- Light rain is possible on Thursday. The best chances (50-80%) will be near Lake Michigan.

- Better chances for widespread rain arrive on Sunday but forecast confidence for this period is low.

- More active pattern looks to develop next week.

Discussion

Issued at 234 PM EDT Tue Oct 27 2026

Once again looking at the potential for some fog development overnight tonight with a light easterly wind that may allow for moisture to advect westward into northwestern OH and northeastern IN locations. Patchy to areas of dense fog will be possible in these locations. Subsequent shifts will be monitoring for this occurrence as there is still some uncertainty due to winds as if they are lighter than expected not too much advection will occur but if winds slightly stronger than more moisture would work it's way into the area increasing the chances and locations that may see fog development tonight.

Much above normal temperatures look to continue through Thursday but a cool frontal boundary associated with a weak disturbance will arrive on Thursday and begin to push a more zonal synoptic flow aloft over the region which will also be accompanied by increasing clouds. Highs into the low to mid 70s Wednesday and Thursday then highs mainly in the 60s expected each day into next week with the increase in cloud cover. A few weak disturbances ripple through the westerly flow bringing chances for light rain showers on Halloween and again on Sunday. On Halloween, the better chances will be over the northwestern portions of the area but amounts look fairly light so likely not too impactful to any festivities. On Sunday, most of the area will have a chance for some light showers.

Sunday into next week a fairly complicated synoptic pattern looks to converge across the central CONUS with both a southern circulation/trof and a northern trof and circulation over central southern Canada. This looks to bring a much active pattern to the area. Latest guidance has a more temporarily cutoff southern feature due to the lack of phasing but systems are expected to potentially phase and this could bring a much colder airmass into the Great Lakes region later next week. Will be watching to see how this evolves over the next few days as this looks to be a potentially impactful system.

Aviation

Issued at 130 AM EDT Wed Oct 28 2026

Midlevel shortwave supporting widespread 12 kft ceilings this morning but low levels remain very dry and VFR conditions will persist. Latest guidance shows a much lower chance for fog development. High clouds briefly scatter later today but return early Thursday morning as a weak cold front approaches the region. No aviation impact anticipated.
