A dry post-frontal airmass is in place and high pressure will continue to build in overhead, suppressing any convection well to our south and west.

Area Forecast Discussion
National Weather Service Chicago/Romeoville, IL
603 AM CDT Tue Jul 18 2023
.SHORT TERM… Issued at 209 AM CDT Tue Jul 18 2023
Through Wednesday…
There are no significant weather concerns during the short term part of the forecast. A dry post-frontal airmass is in place and high pressure will continue to build in overhead, suppressing any convection well to our south and west. A fairly robust lake breeze will press inland this morning and afternoon, holding immediate lakeside temperatures in the mid-upper 70s, with near-80 degree readings elsewhere. Looking like we`ll build a fairly healthy cumulus field as daytime PBL mixing into the base of a 6-8 kft layer of lingering moisture ensues.
A fairly energetic disturbance will pivot across Minnesota and Wisconsin tonight into Wednesday morning, but aside from tossing some additional mid-level cloud cover our way, this should pass through sans fanfare in our region. 925 mb temperature climo suggests–with sufficient insolation–upper 80s/near 90 degree readings should be attainable on Wednesday and have boosted highs a bit to better reflect this.
