Saturday and Saturday Evening …
No Weather Hazards expected …
Gusty northerly winds and extensive cloud cover continue to result in a rather raw April 1 for the area, as surface temperatures struggle to warm into the lower 40s. Fortunately, the cloud cover and surface winds will decrease across the area this evening as a surface ridge of high pressure shifts overhead. This will support a chilly night across the area as the surface temperatures drop into the upper 20s to low 30s. Sunday warmup thanks to a return to breezy south winds and increased sunshine.

Area Forecast Discussion
National Weather Service Chicago/Romeoville, IL
618 AM CDT Sat Apr 1 2023
.SHORT TERM… Issued at 230 AM CDT Sat Apr 1 2023
Forecast concerns include wind gusts through this afternoon and the potential for a rain/snow mix this morning.
Winds have briefly diminished early this morning but are expected to increase toward daybreak as the gradient tightens again ahead of a cold front that will move across the area later this morning. Wind gusts into the 45-50 mph range still look possible and not planning any changes to the wind advisory. Speeds and gusts are expected to steadily diminish during the afternoon with a short period of light and variable possible this evening as a ridge of high pressure moves across the region. Winds will turn southerly by Sunday morning and are expected to gust into the 30 mph range Sunday afternoon.
There still remains uncertainty for rain and snow coverage this morning. Most of guidance shows a slow weakening trend as the precipitation moves across northern IL with perhaps the best chance of mainly wet snow across northwest and far northern IL, where minor accumulation on grassy surfaces is possible, if the snow falls heavily enough. But with marginal air temps and the warm ground, not expecting any impacts on roadways and the preci Pmay be more of a mix of rain/snow. This activity will shift east by early afternoon, across northwest IN.
