KEY MESSAGES

- Seasonably cool temperatures are expected through the weekend with a warming trend back to above normal early to middle next week.

DISCUSSION

Issued at 111 AM CST Sat Nov 14 2026

Lake effect rain showers will mix with snow at times inland and away from Lake Michigan early this morning, as the overall band of precipitation slowly shifts east into northwest IN this morning and then east of the area this afternoon. Not expecting much in the way of snow accumulation, but along the edges of this band of precipitation, where temperatures have cooled into the lower 30s, some minor snow accumulation on grassy or elevated surfaces remains possible overnight. Once this precipitation ends later this afternoon, dry weather is expected through at least next Wednesday.

While overnight low temperatures will be below normal for mid November, in the 20s away from Chicago/Lake Michigan, daytime highs will rebound to near normal by Sunday and then likely above normal every day next week with highs well into the 50s and perhaps pushing 60 by the end of next week. Low temps will eventually warm as well and by mid/late next week, possibly be in the 40s.

Only other weather item of concern to watch for is the potential for fog the next several nights. Light winds at the surface and light winds aloft with limited/no mixing may allow for some shallow/patchy fog to develop Saturday night and again Sunday night. Confidence is too low for any fog mention for now. cms

Northwesterly winds around 10 to 15 kts will prevail today before easing and becoming light/variable overnight. There is a less than 30 percent chance for a brief, light northeast wind shift at MDW this afternoon. At GYY, some intermittent MVFR lake effect cloud cover will be possible today. Elsewhere, diurnal cloud cover with bases around 3-4 kft may develop this morning and afternoon.
