CHICAGO (STMW) - The remnants of Hurricane Patricia pushing up from the South will meet a strong fall weather system from the Northwest to make for a frightful forecast for the Chicago area, with lots of rain and cold weather this week ahead of Halloween.

The rain will begin falling around 2 p.m. Tuesday and continue late into Wednesday afternoon, according to the National Weather Service. Overnight, the chance of rain is 100 percent.

Between three-quarters of an inch and one-and-a-quarter inches of rain could fall in some areas, according to the weather service.

The temperature will also fall from a high of 58 degrees Wednesday as colder air rides in on wind gusts up to 40 mph.

Thursday will be cooler and partly sunny, with temperatures possibly reaching a high of 50.

Friday will be partly sunny, and Halloween weekend will see temperatures in the 50s and a chance of even more rain for trick-or-treaters Saturday.

Not that you’d want to go boating in those conditions, but even hearty boaters might want to think twice. The weather service said winds and waves hazardous to small craft are expected from Winthrop Harbor all the way around the lake to Michigan City, Ind., from Wednesday through Thursday night.

That includes a “high likelihood” of gales from Wednesday afternoon through Thuraday afternoon.
