An anomalously strong mid-level ridge over the central CONUS will anchor omega blocking across much of North America over the next several days. Meanwhile, an elongated surface ridge extending from the Lower Mississippi River Valley to the Canadian Maritimes is in the processes of congealing with another expansive high pressure shifting toward the Upper Great Lakes. As a result, quiet weather with unseasonably warm conditions will continue through the upcoming weekend. As was observed the past few mornings, generally clear skies and light/calm winds should promote shallow fog across primarily interior northern Illinois late tonight through sunrise Thursday.
The blocking pattern will slowly break down early next week as the ridge flattens and a southwestern upper-level low begins to meander toward the central CONUS. A series of smaller troughs on the periphery of a developing longwave trough across the north Pacific and western Canada will eventually pick up the southwestern low. Consensus guidance suggests that the influence of the low on our area could occur as early as Monday night, but more likely Tuesday and Wednesday. Cooler and more seasonable conditions would accompany this system.

- Brief period of some shallow ground fog possible early this morning, primarily at RFD and GYY - There's around a 30% chance of dense fog adjacent to the lake into mainly northeast IL tonight.
Surface dewpoint depressions are generally running several degrees larger than last night at ORD, DPA, and MDW, so potential for VSBY restrictions at those terminals this morning is more more limited. Maintained TEMPOs for IFR/low end MVFR VSBY at GYY and RFD where dewpoint depressions are smaller and on pace with last night. If and where any VSBY restrictions occur early this morning, conditions would likely return to VFR by around 14z.
Calm to very light northeast winds will be the rule today, which should allow for a lake breeze to move inland. Behind this lake breeze, northeast winds of 5-9kt are likely at ORD, MDW, and GYY. An increase in moisture behind this lake breeze opens the door to a potential dense fog problem over primarily northeast IL tonight. Confidence is low, so held off on introducing anything into the TAFs now, but there is probably around 30% chance of LIFR/VLIFR conditions into ORD, MDW, and possibly GYY and DPA.
