The First Official Weekend Of Summer Will Actually Feel Like Summer
While rain is likely later this morning, it now appears that this system will be somewhat weaker with generally light to moderate and very low chance for severe weather or flooding rains. On the positive side though, Thursday afternoon into at least early Friday looks dry! But for today, rain showers will gradually increase in coverage, peaking during the mid afternoon into the night especially along/south of I-88. There will be scattered thunderstorms as well. Some of the rain showers will likely be heavy, especially south, where 1 to 2 inches of rain could occur and possibly result in localized flooding due to wet soil conditions.
An active weather pattern is expected to develop across the Midwest for the next several days. While there will be some dry time, and there is considerable uncertainty in the timing and duration of showers and storms, the pattern supports periods of showers and thunderstorms, with the highest chances from Friday afternoon through Sunday night. A warm and humid air mass will be present, which could also support the potential for some of the thunderstorms to be strong to severe, as well as producing locally heavy rainfall with a risk for flooding. This weekend, there will be many dry hours with a chance for a shower or thunderstorm, more humid high’s around 85 degrees.
