Full sunshine should result in high temperatures in the lower 70s across most of the forecast area. A stray 74-75 degree reading is even possible across in western Chicagoland
(or even the warmest Chicago urban sites like Midway International Airport).

Correction to record highs for today at end of third paragraph.
Through Thursday…
Forecast highlights through the near term period include some minor patchy fog early this morning, well-above average warmth, and increasing south winds on Thursday.
Early morning surface analysis depicts 997 mb low pressure over eastern Montana, and high pressure ridging from Ontario through the central and eastern Great Lakes. A lingering low-level moisture gradient remains across our forecast area, with surface dew points still in the lower 40s mainly along/east of the I-55 corridor this morning. This, coupled with lighter/calm winds closer to the surface ridge to our east, has allowed some patchy shallow fog development in spots. Lansing, Gary and Valparaiso airports have all flirted with 1SM or less visibility early this morning, however drier ground conditions after yesterday`s sunshine appear to be limiting coverage of denser fog. Not expecting widespread dense fog to the degree an advisory would be needed this morning. Northwest of I-55, lower dew points and a little more wind at the top of the shallow nocturnal inversion should prevent much in the way of fog except perhaps in a few typical sheltered/low spots.
The aforementioned Montana low was developing in response to a digging and amplifying western CONUS upper trough, which was also inducing downstream southwesterly flow aloft across the Plains and the Midwest. Within this flow was a mid-level short wave was centered over southeast Missouri, which will propagate east- northeast across the lower Ohio and Tennessee river valleys today. For our local forecast area, we`ll only be along the far northern periphery of this disturbance`s cirrus shield which will barely glance our southeast counties through midday or early afternoon. Otherwise sunny skies are in store for the area, along with modest southerly winds developing in response to the deep low well to our northwest. With low level warm advection gradually strengthening today, our full sunshine should result in high temperatures in the lower 70s across most of the forecast area. A stray 74-75 degree reading is even possible across our western cwa (or even our warmest Chicago urban sites like MDW), where model 925 mb temps approach 15C early this afternoon. This is 15-20 degrees above average for early of November, as average highs for today are generally in the mid-50s. Record highs for today are 76 for Rockford and 78 for Chicago.
The surface pressure gradient gradually tightens across the region tonight, maintaining south winds around 10 mph which will keep temperatures from dropping off below 45-50 degrees. Winds may even remain or become a bit breezy overnight, especially across the northwest half of the cwa as a 30+ kt 925 mb low level jet develops above the more-stable boundary layer. Southerly winds continue to strengthen Thursday as the gradient tightens further, and gusts to 30+ mph are likely during the afternoon especially across the northwest half of the forecast area. Despite a little more patchy high clouds than today, 70+ degree warmth will continue.
