FORECAST IN DETAIL
The holiday season itself may have to put you in a festive mood this week, because the weather probably will not. Clouds and rain are in the forecast daily. It won't rain the whole time, but err on the side of having your umbrella with you lest you get doused on the way to a holiday party. You'll also need a coat, but with the exception of tomorrow and maybe Wednesday, not a real heavy one.
Today (Monday): Lots of moisture from the south will spill into the region, giving us not only dense cloud cover and sprinkles, but also mild temperatures. Most locations should hit 60, with lows 60s and even mid- 60s within reach. Confidence: Medium-High
Tonight: A cold front will drive through the region, bringing a good chance of rain showers (70% chance). Temperatures will steadily fall behind the front to near 40 by morning. Confidence: Medium-High
Keep reading for the detailed forecast through the week.
Tomorrow (Tuesday): As tonight's cold front stalls to our south, waves of low pressure will develop along it. The first of these waves will bring a solid chance of rain (60% chance). It will be a cold rain, with highs only in the low 40s.Confidence: Medium-High
Tomorrow Night: Rain is likely. As temperatures slowly fall into the 30s, the northwest suburbs could see the rain mix with or change to sleet. Lows will range from 32-36 (suburbs-city). Confidence: Medium
On Wednesday, scattered light precipitation is possible as the front stalled to the south may lift northward as a warm front. Temperatures should climb into the 40s, so any mixed precipitation in the north and west suburbs will likely change back to all rain. Throughout the day, the precipitation will probably decrease in coverage and intensity. It remains cloudy overnight, with a 30% chance of showers. Lows should be near 40. Confidence: Low-Medium
Winds from the south may help us warm back up to 50 on Thursday, but clouds will stick around with a chance of rain (30%), especially in the morning. Mostly cloudy overnight, with lows in the mid 40s. Confidence: Low-Medium
Mid-50s are a possibility for highs on Friday ahead of another cold front, which may bring another round of showers by afternoon (30% chance). Partial clearing is possible overnight, with lows 35-40 (suburbs-city). Confidence: Low-Medium
The weekend may bring more unsettled conditions with a chance of rain Saturday afternoon through Sunday afternoon as another front gets hung-up in our vicinity. Temperatures should generally be in the 40s. Confidence: Low

OK I see the big line of rain coming. But this is very difficult. I am planning to be walking around downtown from 4-7:30 or so. It's going to be here by then, isn't it?

Laura -- this is clearly too late for you, but don't think we'll be seeing more than sprinkles in the area until after your walking time.

53 degrees and cloudy in the Valley, .02 rain overnight.
The friendly "heat ridge" over the southeast, that has became all too familier during the past 4 winters, irregardless of the ENSO condition, has returned.
This will result in an unsettled week as we are in the battle zone between cold to the north and warmth to the south. Most of our area should be free of wintry precip., but later tomorrow and tomorrow night could be a close call with an overrunning sit. with cold H.P. to our north.
Things begin to change next weekend and into Christmas week as the "heat ridge" begins to break down and we return to a more wintry pattern.
