Series of Thunderstorms Possible 11 PM to 5 AM
A strong “pneumonia” front is expected to dive south across Lake Michigan Sunday afternoon, which will lead to a rapid drop in temperatures for areas along the lake shore and adjacent inland areas, according the National Weather Service Office in Chicago. Development of fog is expected along the Lake Michigan shoreline.
Most Lake Michigan water temperatures are still in the 40s currently in early May.
Arlington Heights Forecast
84°F at 2:00 p.m.
60°F at 9:00 p.m.
Arlington Heights and nearby communities are expected reach about 84°F around 2:00 p.m., but temperatures will begin falling noticeably around 4:00 p.m. Arlington Heights and nearby temperatures will fall to 60°F by 9:00 p.m.
Lake Forest is forecast to reach about 75°F and fall to 50°F by 9:00 p.m. The air temperature in Kenosha is already 59°F, but Green Bay is 71°F at 12:25 p.m. Arlington Heights is 80°F at 12:25 p.m.
The development and location of thunderstorms tonight depend on the location of the warm front to our south. The cold front could push any developing thunderstorms south of Chicagoland; however the cold front clash with the warm front to the south could bring a series of thunderstorms known as ‘training thunderstorms’ (like a railroad train) with flash flooding. If the cold front moves in ahead of the developing storms along the warm front, then storms may be less severe with flash flooding.
Damaging winds, hail, and even flash flooding may occur south of a line between I-88 and I-90 from 7 PM to 12 AM. Additional storms for the rest of northern Illinois may arrive from the west after 12 AM.
The second set of storms could move across northern Illinois, especially between midnight and 5:00 a.m., but according to NWS Chicago will be “mainly south of I-80.”
Total rainfall in Arlington Heights is likely to be between 0.60″ and 1.0″ — beginning about 8:00 p.m. Sunday night and including the entire day Monday.
Weather Radar in northern Illinois was clear at 12:25 p.m.
