The Daily Parker

Politics, Weather, Photography, and the Dog

Cold open

Just 3% of New Year's Days have been this cold in Chicago since we started keeping records in 1871. The normal temperature range for January 1st is -9°C to -1°C; right now it's -17°C, noticeably warmer than the overnight low of -23°C. That overnight temperature actually tied for the second-coldest January 1st on record. Only 1969 was colder. If the daytime temperature stays where it is, we'll set a new record for the coldest January 1st in history.

The forecast calls for warming temperatures next weekend, but with a string of -17°C–degree nights until then. It discourages me from leaving the house. Even Parker hasn't liked going outside the past two days, despite his boots and two fur coats.

The silver lining to this frozen cloud is that there is a real possibility that today will be the coldest day of 2018. Despite what people believe about Chicago, days below -18°C are pretty rare: even during the Polar Vortex of 2014 when we set the record for most days at that temperature, we only had 26 of them. And it's even less likely that we'll stay below freezing for the entire month of January; the record for that is 43 days, set from 28 December 1976 to 8 February 1977. We'd have to go through February 5th without getting above freezing to set a new record.

In other words, the probability of having any more days this winter dropping down to -23°C is pretty small.

At least, that's what I told myself when I walked Parker this morning.
