Lake County Flood Warning Issued Due to Lake Effect Rain

Lake effect rain brought freezing temperatures and flood warnings to parts of the Chicago area and Northwest Indiana on Friday, November 14, 2026.

The persistent precipitation has lingered for roughly 24 hours, fueled by moisture coming off the lake. While heavier rain fell earlier in the day, forecasters said the system was changing.

“No, afortunadamente el fin de semana ya veremos mejoría, pero por lo pronto todavía nos quedan unas horas con esta lluvia por efecto lago que ha estado ahí prácticamente desde hace 24 horas y más temprano tuvo algunos momentos fuertes,” said a meteorologist on Univision.

The National Service of Meteorology issued a flood warning specifically for Lake County remaining in effect through Saturday morning. The advisory also covers a small strip of the Illinois border in Cook County.

Temperatures dropped to 36 degrees near the downtown lakefront late Friday, while wind gusts pushed wind chills down to 27 degrees. Overnight temperatures were projected to hover between 34 and 35 degrees across the immediate region.

“Ahora mismo vemos como sigue cayendo y no descartamos que en el transcurso de la mañana algo de mezcla pudiera estar ahí presente, incluso algunos copos,” the meteorologist told Univision regarding the shifting overnight weather patterns.

Forecasters expect the lingering precipitation to end by Saturday afternoon, paving the way for stable and sunny conditions on Sunday. Temperatures are anticipated to reach a high of 48 degrees on Saturday and 49 degrees on Sunday.

While morning wind chills will remain in the 20s for areas like Aurora where temperatures hit the freezing point, next week brings a return to above-normal temperatures with extended periods of sunshine.

“La buena noticia es que el centro de predicción del clima nos tiene en el área de posibilidad de temperaturas por arriba de lo normal, y eso lo notaremos la semana entrante en que tendremos periodos de sol,” the meteorologist told Univision.
