Wintry weather expected to follow today's rain

November's been a mild month weather-wise — no days that remind you of mid-January and a lot of days that are a tick or two warmer than expected.

But all good things come to an end, and today's rain could signal the real beginning of winter in Chicagoland.

It's expected that the rain will arrive in late morning, and WGN-TV meteorologist Tom Skilling said it'll be the biggest rainfall we've had in a couple of weeks, up to an inch in some places. Skilling also noted that colder weather will start arriving Saturday night, ending a string of November days that were unseasonably mild.

Look for Sunday's high to only be in the 40s — about 20 degrees lower than it was Friday — with a low in the high 20s. Temperatures will stay in that range during a week that will be mroe cloudy than sunny, with some warmer days followed by colder ones.

No measurable snowfall, meaning more than .1 inches, has landed so far this season, an unusual occurrence Skilling noted. But it may happen this week, perhaps Sunday or later in the week as we move into meteorological winter (December through February).

And if November has been full of good weather news around here, Skilling says December won't be following that lead in its early days with temperatures expected to run below normal.
