An Omega block that is in place over the CONUS is expected to persist through the end of the week. The associated ridge axis will only ever so slowly crawl eastward over the coming days, which will maintain broad surface high pressure across the region. As a result, dry conditions with an abundance of sunshine will continue through the remainder of the week with high temperatures remaining above to well above normal for this time of year. Daily lake breezes will cause the coolest (low- mid 60s) high temperatures to be observed near Lake Michigan each day.
Much like last night/early this morning, optimal radiational cooling conditions will likely allow for fog to develop late tonight into tomorrow morning and possibly again in the coming nights/mornings. This will particularly be the case in and near the Chicago metro within the footprint of the marine-influenced air brought inland during the daytime, where the fog could become dense once again.
There is pretty good ensemble agreement at this point in time that the blocking pattern will break down by early next week. This will allow for a cold front to drop through the region sometime on Monday or Tuesday, resulting in a return to cooler and more seasonable temperatures for the middle of next week. The frontal passage may bring a chance for precipitation to the area early-mid next week, but support for this across the latest suite of ensemble guidance is not ubiquitous, and there are considerable temporal differences with when this next potential opportunity for precipitation may arrive as well.

Key Aviation Messages for the current TAF period:
- Fog, locally dense, is possible prior to sunrise, mainly at Chicago Terminals north of a KARR to KMDW line.
Winds are expected to be light and calm through the night. There is another chance for fog to develop this morning. It has already started to develop around and north of KENW where obs are already reporting 1/4SM. While fog development is not a certainty, if/when it does occur, it can be locally dense with vis potentially near zero. Similar to yesterday, vis improvement should be fairly quick after sunrise.
Light southwest winds are expected through much of the day before becoming more southeasterly toward sunset. Once the fog clears, VFR conditions are expected through the end of the TAF. There is another chance for patchy fog tomorrow morning, but the chances are not as great as recently.
