Area Forecast Discussion
National Weather Service Chicago/Romeoville, IL
552 AM CDT Fri Oct 28 2022
Issued at 320 AM CDT Fri Oct 28 2022
Quiet weather is on tap heading into the weekend as expansive surface high pressure remains dominant across the Great Lakes into New England. A wavy upper jet pattern is in place across the CONUS with a narrow positively tilted upper trough / semi-cut-off closed upper low continues to slowly drift east into the Southern Plains with upper ridging building across the west.
Closer to home, today looks like another beautiful fall day with light east to southeast winds and high temperatures in the upper 50s to lower 60s. High level cloudiness will continue to shift east early this morning with mostly clear skies expected for much of the day. Temperatures dip into the mid 30s again tonight (lower 40s along the shore and central Cook County). Did add a mention of fog late Friday night into Saturday morning for portions of northern/northeast IL given clear skies, calm winds, and low dewpoint depressions. Model guidance has trended a little less pessimistic with the 6Z guidance so opted to keep the coverage wording as “patchy” for now.
Saturday will be similar to today, perhaps just slightly warmer with highs in the lower to mid 60s (upper 50s along the IL shore). Once any lingering fog burns off in the morning, we start the day mostly clear with increasing clouds expected later in the afternoon as our next weather system approaches.
