Saturday and Saturday Night …
Weather Hazards expected …
[Data missing] Hazardous weather might have been strong non-thunderstorm winds; southwest winds in the 35 to 40 mph range Saturday afternoon and Saturday evening. Wind gusts peaked between 2:00 p.m. and 3:00 p.m.
DISCUSSION…
Temperatures will slowly rise Saturday morning and will continue to rise into Saturday afternoon. Highs Saturday and Sunday are likely to reach the lower to mid 40s south of I-80, but there remains uncertainty for highs over the deeper snow pack across northern IL and have
capped highs both days in the mid 30s. Across the Chicago metro, upper 30s to near 40 seem possible.
Daily low temperatures and daily high temperatures are on the way up. We’re gaining about 2 minutes of daylight every day in the progression toward vernal equinox, March 20, 2023.

Area Forecast Discussion
National Weather Service Chicago/Romeoville, IL
537 AM CST Sat Feb 4 2023
.SHORT TERM… Issued at 118 AM CST Sat Feb 4 2023
Through Sunday…
Primary forecast concern is strong/gusty southwesterly winds today into tonight.
High pressure is shifting east early this morning and the gradient will steadily tighten today with southwest winds gusting into the 35 to 40 mph range this afternoon and this evening. There remains some uncertainty for how frequent the strongest gusts will become and its possible prevailing gusts may remain in the 30 mph range with the highest gusts less frequent, but overall confidence is low. A weak cold front will move across the area Sunday morning, shifting winds westerly. Gusts into the 25 mph range will be possible on Sunday.
Temperatures are now slowly rising and will continue to rise into this afternoon. Highs today and on Sunday are likely to reach the lower to mid 40s south of I-80, but there remains uncertainty for highs over the deeper snow pack across northern IL and have capped highs both days in the mid 30s. Across the Chicago metro, upper 30s to near 40 seem possible.
Some of the guidance is suggesting some fog may develop Sunday morning across parts of northwest IL. While dewpoints may reach the lower 30s and there will be a front passing across the area, confidence for fog is fairly low and no mention with this forecast. Lower ceilings may be more likely than fog, but trends will need to be monitored.
