The National Weather Service has issued a tornado watch for
the Chicago area until 8 p.m.
McHenry, Lake, DeKalb, Kane, DuPage, Cook, LaSalle, Kendall, Grundy, Will and Kankakee counties are all impacted by the watch, as the Chicago area could potentially see severe thunderstorms during the afternoon hours.
The National Weather Service has also issued a tornado watch for Kenosha County in southeast Wisconsin until 8 p.m.
Scattered ping pong ball-sized hail is also possible, along
with wind gusts of up to 70 mph, according to forecast models.
According to the National Weather Service, most of northern Illinois is under an “enhanced” risk of severe weather for Saturday, with the far eastern portions of Cook, Will and Kankakee counties under a “slight” risk of severe storms.
Those storms are expected to bring intense lightning, and there is a moderate risk of heavy rains, flooding, damaging winds and large hail.
Those storms are expected to begin developing in the early
afternoon hours, with partly-to-mostly cloudy skies preceding their arrival.
Areas of patchy fog are also possible in the morning hours before it burns off
by the noon hour.
High temperatures in the city are expected to reach the
mid-70s, with cooler conditions along Lake Michigan. In the suburbs
temperatures could rise into the high-70s and even into the low-80s before rain
showers begin developing in the western suburbs just after 1 p.m. Those showers
will move through the Chicago area in the mid-afternoon hours, and
thunderstorms are expected to begin developing around that time.
Things are expected to be drier in the area on Sunday, but
much warmer and still extremely humid. Temperatures are expected to reach the
high-80s and could even touch the 90-degree mark in some locations, and those
conditions will remain in place on Memorial Day itself.
