It was -48 at Wisdom, MT on 2/6. That was an impressive cold wave for MT. Missoula hit -23 which was their lowest since February 1996.

Thx WxStatman...I've been pulling my numbers from a combination of WPC Daily National Extremes and the monthly overview report which lists daily records from GHCN stations (COOP, ASOS). Thing about GHCN is they have a 00z cutoff so sometimes the high temps are from the day prior. This is due to WMO standardization requirements of a midnight Greenwich cutoff.

Is it okay if I post the Canadian monthly extremes here? Better to ask forgiveness than permission, so here goes...

 

January:

16.8°C (62.2°F) CLARESHOLM, ALBERTA   note: Second place at 16.5°C was BURWASH, YUKON!! 

-48°C (-54.4°F) ST PRIME, QUEBEC

 

February:

15.0°C(59°F) TAHSIS VILLAGE, OLIVER, & CHROME ISLAND, BC

-50.4°C (-58.7°F) EUREKA, NUNAVUT 

 

March:

18.5°C(65.3°F) NOOTKA LIGHTSTATION, BC note: WHITE ROCK, BC at virtual tie at 18.4°C

-47°C (-52.6°F) EUREKA, NUNAVUT

 

April:

28.5°C (83.3°F) HEMMINGFORD, QUEBEC

-43°C (-45.4°F) EUREKA, NUNAVUT

 

May:

35.4°C (95.7°F) SWAN RIVER, MANITOBA

-26.6°C (-15.9°F) TALOYOAK & HALL BEACH, NUNAVUT

 

June:

34.7°C (94.5°F) FORT SEVERN, ONTARIO

-13.3°C (8.1°F) AULAVIK NATIONAL PARK, NUNAVUT

 

July:

41.7°C (107.1°F) ASHCROFT, BC

-4.7°C (23.5°F) ISACHSEN, NUNAVUT

 

August:

40.1°C (104.2°F) LYTTON, BC

-7.1°C (19.2°F) CHETWYND, BC note: Both extremes are in BC

 

September:

38°C (100.4°F) MUENSTER, SASKATCHEWAN

-22.9°C (-9.2°F) SVARTEVAEG, NUNAVUT

 

October:

29.0°C (84.2°F) ST-ANICET, QUEBEC

-35.2°C (-31.4°F) EUREKA, NUNAVUT

 

November:

21.3°C (70.3°F) ST-ANICET, QUEBEC

-42.3°C (-44.1°F) KUGAARUK, NUNAVUT Note: HENDRICKSON CREEK, ALBERTA WAS CLOSE BEHIND AT -42°C.

 

December:

18.5°C (65.3°F) GREENWOOD, NOVA SCOTIA

-44.3°C (-47.7°F) SHEPHERD BAY, NUNAVUT

 

 

Note: In most years the Yukon is the national cold extreme, but not in 2014, nor 2013 for that matter. The national cold spot was in the Yukon for 6 years in a row, but Eureka, Nunavut has been for two years in a row now. This is the first time in history that Eureka has been the extreme cold spot two years in a row. Since records began in 1947, Eureka has been the national cold extreme 5 times, with three of them occurring since the year 2000. Not sure what that means.

Glacier, no problem. This is a forum not my personal blog. Even if it was the latter I would love to see stuff like that from other areas of the world.

Where is a good source for daily temp extremes in Canada? I assume the same place you got this info.

I don't know where to go for daily extremes, but I know where to go for monthly summaries.

^This past month was the warmest winter month ever recorded in Canada. The average temperature at Quatsino, BC was 9.5C/49.1F for the month. By contrast, it was the coldest month on record in many parts of Quebec and Ontario.

Glacier are you familiar with the CNRA network of weather stations in Canada? In the province of Ontario they have an especially good network of remote weather stations...the stations at Devious Lake and Rinker Lake have achieved daily minimums for all Canadian stations (ie colder than those in the high Arctic on certain days).

Just this year (all the lowest temp for the date within Canada):

 

Devious Lake, ON
-53 Feb 19th
-43 Feb 22nd

-46 Feb 23rd

-46 Feb 26th

Rinker Lake, ON

-39 Jan 10th
-42 Jan 11th

 

Appears they both just came online this past December. No data available prior to Dec 2014.

No, I'm not familiar. I'm still trying to figure out how to find the weather extremes for Canada from your link provided above without looking at individual stations. Is there some sort of way to filter and sort the entire country, or at least by province?

I think for stations without daily summaries (just hourly obs) you will have to comb through the data. The Env Canada monthly summaries fail to include those for some reason. I utilize an interface called "Mesowest" at University of Utah to access those hourly stations and they have a nice 5-day tabular interface. Here is the current one for Ontario (you can modify province and end date).

http://mesowest.utah...=2015&orderby=n

You will have to scroll down for each day to determine which site had highest/lowest temperature. I go through each province in 5-day increments to find daily extremes for Canadian stations. Some of these stations are hourly obs so they aren't easily searchable on Env Canada.

There is also the IEM database at Iowa State that includes these same Canadian stations.

Thanks for that. Very interesting, but I notice that a lot of Environment Canada weather stations are not on the list. For example, for BC, 4 of the first 5 I looked for aren't there. No Ashcroft (the only place in Canada that is classified as arid), no Lillooet, no Puntzi Mountain, and no Tatlayoko Lake.

True...it's not complete. Those stations you mentioned are kinda like our COOP stations here in the US where an observer "calls in" their max/min and precip each day. The stations listed on Mesowest are only those that report an automated hourly obs, so most all Canadian airports/aerodromes should be on Mesowest. However, as you noted there are some stations that give hourly obs that don't show up in the provincial monthly summaries, such as La Grande III airport (CYAD) and Gameti, NT for example. I think it behooves us to look at both Mesowest and Env Canada data so as to not miss potential records.

 

Another nice aspect of Mesowest are their QC flags.

I wish Environment Canada had a similar 5-day Max/Min table where you could select province and date.

Actually, all the weather stations I listed above are EC hourly reporting stations. The flags are BS in a many aspects. I just did quick look at the July 17, 2014, and notice that it flags the Bella Coola airport even though the data is reasonable and accurate. 

 

I agree though, QC flags can be useful, and I too wish EC had a similar table.

Looks like Mesowest only includes the ASOS, DCP networks and some personal weather stations in their database...like I said it's more useful in conjunction with Environment Canada's website.

QC isn't perfect by any means but it is better than no filter in many cases. I believe it is less reliable in remote areas because it compares a station's reading to its neighbors.

Or near the water. Bella Coola can be over 100 degrees 5 miles inland while weather stations closer to the ocean might be struggling to hit 70 degrees. I think this is why Bella Coola was flagged.

-57 in Quebec is pretty amazing...what has the province gotten down to in previous winters?

 

I don't buy that Richmond Nature Park +19.5c...next closest values are Chilliwack and Zeballos Muraude Creek, both of which reached only 16.5c (63 F). This still falls short of what appears to be a reputable 17.9c at Champion, AB. Surrounding areas recorded  17.1c (Etzikom), 17.2c (Grassy Lake), 17.1c (Lethbridge), 17.2c (Milk River).

I agree with your assessment. I wasn't sure if I should write that one off, but didn't have time to keep going. Plus, Fort Liard, NWT was reliably 12.5C last month (and the warmest place in Canada that day), so it's not out of unexpected for BC to reach 19.5C during the warmest winter month and winter on record.

 

As for Quebec, it can get cold in the middle even if the south isn't that bad. It is the largest province after all. 

 

As an aside: this past month was the coldest winter month on record in the east, while it was the warmest on record in the west. This contrasts to January 1950, which was the coldest on record in the west and the warmest on record in the east.

 

Back to Quebec, it has been the Canadian annual extreme cold spot 6 times since 1900. The last time was 2003 when La Grande 4 was −50.4 °C (-59 °F). The record low for Lac Benoit is -50.1°(-58°F) from 2002, and the record for Quebec is −54.4 °C (-66 °F) from February 5, 1923.

I've created an Excel spreadsheet showing extreme max and min on a monthly basis for each Canadian province and each US state. US state extremes I pull off of the NCDC state climatological summaries (usually a 4-6 month lag). For more recent months I will start using Mesowest to get a rough draft.

Of note it appears Corner Brook, NL set a new Feb monthly snowfall record for the province with 88.4" (224.4cm) beating previous record of 82.3" recorded at Makkovik in Feb 1987.

 

The snowiest single month in the province appears to be 102.5" recorded at Nain in Jan 1970 HOWEVER Hopedale reports 310.8mm of precip this past Feb. With the max temp for the month only -2.8c it seems likely all of it was snow. If so, and using a 1:10 ratio, 310.8 cm (122.4") of snow fell (probably more as it would be drier snow at those low temperatures). If so it indeed shatters the previous provincial record for Newfoundland and Labrador.
