In many years of late, December 5 has meant snow and/or cold. Departing from recent history, this Dec 5 is mild and precipitation free. Rain showers enter the picture later tonight and especially Tuesday and Wednesday. By Thursday, cold air bleeds in and, depending on track of a storm system moving through, we may deal with precipitation types besides rain (especially in the colder north and west suburbs). Drying out and cold Friday through the weekend.

Today (Monday): Patchy fog greets some morning commuters - especially east of I-95; otherwise, skies are mostly cloudy for the better part of the day. I can’t entirely rule out some sunnier intervals. Mild breezes (near 10 mph) from the south give temps a lift up towards 60 or so. Confidence: Medium-High

Tonight: An unseasonably mild evening lies ahead as southerly winds put a big break on temps as do pervasive clouds. Lows range from 50-55. After midnight, I can’t rule out a shower or two (30% chance) but think most spots stay dry overnight. Confidence: Medium-High

Tomorrow (Tuesday): A cold front edges towards the region increasing shower chances. This doesn’t look to be an all day rain, but there’s a 60% chance of on and off showers. Temperatures remain mild ahead of the front, with highs 55-60. Confidence: Medium-High

Tomorrow night: Rain showers remain likely (60-70% chance) as the cold front finally crosses the area. It slowly turns cooler, with lows 40-45. Confidence: Medium


Mostly cloudy and cooler Wednesday during the day behind the cold front. Highs struggle to reach 50. Rain (or rain mixed with snow north and west suburbs) may redevelop Wednesday night as the front stalls to our south and southeast and low pressure develops along it. Lows range from 34-42 (suburbs-city). Confidence: Medium

A chance of rain Thursday as the low pressure area to the south moves north or northeast. We may stay dry if the low tracks far enough east. If the low tracks close enough, with colder air seeping into the region, there’s a chance the rain mixes with and changes over to sleet and/or snow, mainly in the north and west suburbs. Highs are around 40 and Thursday night’s lows range from 31-37 (suburbs-city). Confidence: Low-Medium

Seasonably cold high pressure builds into the region Friday through Sunday. All three days should have a fair amount of sunshine (maybe a few more clouds on Friday compared to the other days) with Saturday the coldest day. Highs are 45-50 Friday and Sunday and just 40-45 on Saturday. Overnight lows are in the low-to-mid 20s to low 30s (suburbs-city). Confidence: Medium
