Area Forecast Discussion
National Weather Service Chicago/Romeoville, IL
627 AM CDT Mon May 29 2023
.SHORT TERM… Issued at 1240 AM CDT Mon May 29 2023
Only forecast concern is the dewpoints, which continue to be lower than guidance forecast. Dewpoints mixed out Sunday afternoon allowing relative humidity levels do dip into the middle teen percent range across many areas. Maintained lower than guidance dewpoints for both today and Tuesday though there is some uncertainty for increasing dewpoints later Tuesday afternoon. As a result, with highs warming a few degrees each day, afternoon minimum relative humidity levels will once again be in the 20 percent range today, perhaps a little higher on Tuesday. Other than the lake breeze pushing winds into the 15 mph range, winds are not a concern today or Tuesday. Thus, not planning any elevated fire danger mention. Northeast winds along with the lake breeze will keep areas near Lake Michigan cooler today and Tuesday. Passing mid/high level clouds will likely be sufficient enough for partly cloudy wording though there may be periods of mostly sunny and some periods of mostly cloudy.
