The good news is that right now it's 21°C out. The bad news is...well:
The Tribune reports:
Northern Cook, Lake and McHenry counties were getting hit hardest, according to the National Weather Service.
By 8 a.m., the weather service received numerous reports of standing water — some as deep as 25 cm in Mundelein, where homes were flooded and residents had to be rescued by rafts.
A flash flood emergency was issued for Lake and northeastern McHenry counties and will remain in effect until 11 a.m. Wednesday, according to the National Weather Service. Already, 5 to 8 inches of rain had fallen in those areas with an additional 25 to 75 mm likely.
Metra's Milwaukee North Line service has been suspended between Fox Lake and Libertyville because of flooding. Further south on the line, Metra is providing minimal shuttle service between Lake Forest to Chicago.
Fortunately, I got to the office well before the first line of storms hit. Unfortunately, shortly after snapping the photo above, the second line hit. Fortunately I was only a block from the office.
