will be in the Twin Cities early next week where I just bought a lake house. P&C in Roseville, MN (North of St Paul) is a high of -8F Monday and low of -20F on Monday night. F-U-N. 

Up in Bloomington for the weekend and driving back Sunday. Dry roads made all the difference today. Not so sure about Sunday.

Ugh. My furnace is definitely playing catch up, but still humming. Stay warm Jim.

I moved out of my house on the 17th of January. My gas billing cycle ends on the 16th. So they read my meter on the 16th, for my normal bill; then they read it again on the 17th to give me a final bill. I used $14 worth of gas in one day. My poor furnace was running nonstop.

Good thing it's the buyers problem now.

(cross-posted from clipper thread as this is where it belongs) ...

 

Thanks, beavis for the Chicago January numbers.

 

Factoring in today's values, currently sitting near 16.5F mean temp, which represents 17th coldest in 142 years (1873-2014) and projected to drop further to end up possibly 8th between 1918 and 1963 (13.3, tied 6th) and 1985 (14.4, now 8th). Only 1977 (10.2), 1912 (11.9), 1893 (12.1), 1982 (12.2) and 1979 (12.4) were colder than all of the above.

 

To break 13.3 after today's known values would require close to a zero F mean 24th to 31st while the projections are closer to 5 F which leaves the month at about 14.0, 0.4 colder than 1985 which may or may not be safe, and 0.9 colder than 1888 (currently 9th and in need of midnight highs and such to escape dropping to 10th). Almost certain to be passed are 1978, 1994 and 2009 all tied for 10th (15.9), 1875 at 13th now (16.1), 1887 and 1940 tied for 14th (16.3), and soon to feel our wrath 1883 (16th at 16.4).

 

If there were records from 1841 to 1872 as with Toronto, only 1856 and 1857 appear likely to get onto this list for certain, 1872 possibly. Would imagine 1857 would then hold first place but 2014 could pass the other two. That would then make it eventually somewhere around 9th or 10th coldest in 174 tries.

 

Will update as we pass various benchmarks.

I'm thinking I might have to sell one of my kidneys on the black market to pay for some of the heating bills coming up.

The one thing about a midnight high is that it usually the previous day's low, so that the effects on monthly mean temperature is diluted. In any case, climatology suggests an average of 4-6 midnight highs (at front end) as well as 2-3 at back end of days in January and February.

 

When I was keeping records (mostly 1964 to 1977) in Ontario, I was amazed as a total weather novice when temperatures would often peak around midnight in warm sectors. I can recall Jan 8, 1965 as the first really dramatic instance of this (in my experience). I've seen some really strange temperature trends on a few occasions, recall one time in that same winter it was about 40 F at 0300h and 5 F at 0700h.

 

As to that request about Toronto and Ottawa, I would just say, get your list of past extremes as I don't have one available either, then find out where these stations sit as of today (after 23 days) and take about two Celsius degrees off those values to estimate the finishing point (based on models tonight). I would imagine that the anomalies are closer to normal now for YYZ and YOW than for ORD, as I am tracking sites in the northeast U.S. which have only recently dropped back below zero anomalies after a cold start and that mild period mid-month. The Ontario sites will be less into the negatives than Chicago at this point but they will now keep pace in falling off. It probably won't end up much colder than about a 25th coldest in 100 years sort of position. Sunday-Monday won't see much of a fall for Toronto temp anomalies.
