It's  no longer an active station, but Fremont 5 NW in Oregon actually has a wider range:

Tujunga, CA (15 miles N of Downtown L.A.) - Elev. 1,860 ft.

 

Eugene, OR (5 miles SSW) - Elev. 850 ft.

Impressive, but that is not it. Boca is below 40ºN.

 

Another hint: It's in the Klamath Mountains.


No rain here until Hour 258.

Interesting.

The largest range I know of is 50.5 degrees at Thistle Utah (35.9 to 86.4 degrees), but that station is no longer operating. Thistle was wiped out in 1983 when a mudslide dammed the Spanish Fork River creating a lake 200 feet deep and three miles long. It completely destroyed the entire town:

https://en.wikipedia...i/Thistle,_Utah

Of note, WRCC gives a slightly lower diurnal range than the weather almanac I have, but I'm not sure why. It's still near 50 degrees.

Thistle does have a shorter period of record than Fremont though. The record at Thistle is only five years, so it may or may not count

I can't think of anywhere in Oregon or California that could beat Fremont, so I don't know.

So, what's the answer?   We're waiting to hear.   :)

It is interesting that the difference in night temperatures between August and January is only 16.7 degrees; while the difference in highs between those months is much greater.

Regarding the Aleutians - I see no reason to doubt the late-season record lows. Their ability to see extremely cold minimums is usually dependent on the amount of Bering Sea icing, which peaks in early spring. 

 

The -15F at Attu in November 1986 is obviously bogus. Probably a data input error. You'll see those pop up once in a while in the WRCC database. 

 

Do you have a source for the -26F reading at St. Paul in January 1919? I can't find it anywhere. The COOP data for St. Paul @ the NCDC cuts off at 1916 and doesn't resume until the 1940's. The thing is though, that reading is not out of the realm of possibility. There actually was a verifiable, major cold wave occuring in SW Alaska in late January 1919. Nome bottomed out at -47F on 1/25 and then hit -46F on both the 28th and 29th. The -47F on 1/25/1919 stood as the all-time record low for Nome until they hit -54F in January 1989. You can also cross-reference the -19F reading @ St. Paul on 3/14/1971, as Nome hit -46F on the 11th and -44F on the 13th. 

 

If you are interested, scroll down on the following PDF which has records from St Paul Island dating back to 1917:

2017 had such a well-defined seasonality curve at PDX. It's interesting looking back on it. 

 

33.5 in January

73.6 in August

39.8 in December

 

About the only other years that compare are 1972, 1985, and 2009, at least by comparing the curve of monthly averages.

Interesting nugget: Dawson Creek, BC (2,147 feet) has its all-time greatest single day snowfall in August! 35.3 cm fell on August 17, 1973 which is just shy of 14". 

 

This was a very cold trough which also brought monthly record lows to the PNW, including 33 at Olympia.

Nice.

Barrow, Alaska has its 6th greatest daily total in July. 

 

15.0 on 10/26/1926

7.3 on 1/8/2001

7.0 on 3/25/1963

6.5 on 12/4/2011

6.4 on 11/17/2010

6.0 on 7/29/1922

Prudhoe Bay had its snowiest day on 6/10/1987.

 

That part of Alaska is pretty cool year round though.

 

In the Lower 48, Montana has its 24 hour record snowfall in late May.   The record was 48" on 5/28 to 5/29/1982 at Snonkin.

From Wunderground:

 

Nate’s trek north helped reinforce a very warm, moist air mass in place east of the Appalachians. Summerlike dew points in the 70s led to unusually muggy conditions for early October. The low temperature on Sunday at Washington’s Reagan National Airport was 75°F. In records dating back to 1874, that was the city’s warmest daily minimum ever recorded in October, breaking the 74°F record set on October 4 and 5, 1898, and October 4, 1941. Capital Weather Gang reported that the mid-70s dew points were virtually unprecedented for this late in the autumn. All-time warm daily lows for October were also set at Washington’s Dulles Airport (73°F) and Philadelphia (74°F). Conditions in D.C. on Sunday were so oppressive that the annual Army Ten-Miler Road Race was cut short and recast as a “recreational run,” according to Stars and Stripes.

 

Just wanted to highlight a truly remarkable heat wave that affected the mid-Atlantic in early October 1941. In addition to the record warm minimum of 74, Washington DC also set its still-standing monthly record high of 96 on the 5th of that month. Philadelphia posted 96-95-93 on the 5th-7th, while no other October in history even topped 91. Likewise, Wilmington DE posted 94-93-93 on those dates while no other October reading in history exceeded 91. NYC-Central Park hit 94 on the 5th while the next highest Oct reading is also 91, in a period of record back to 1869. Richmond VA reeled off 97-99-95-95 on the 5th-8th, it wasn't until 10/9/2007 that Richmond saw any other October reading crack 95 degrees (Washington DC hit 94 on 10/9/2007, also the closest they've come to Oct 1941). State record maximums for October were set in Virginia (101 in Walkerton), Pennsylvania (100 in Phoenixville), Maryland (99 in Blackwater), New Jersey (97 in Tuckerton), and Delaware (97 in Bridgeville).

 

And just like that, the October 1941 heat wave (previously untouchable in the 78 years since) has been matched or exceeded in many places last week in the mid-Atlantic. There were at least 10 states that set/tied October monthly records Wednesday and Thursday, including some of the ones listed in my post above. 

 

Wunderground has a great writeup (pasted below). In addition, it appears Virginia also broke their monthly state record with a reading of 102 at New Boston (as well as 101 in Petersburg) - previously 101 at Walkerton in October 1941. 

 

https://www.wundergr...ven=cat6-widget

 

 

At least nine states set or tied their highest temperature for any October

Even more impressive than local heat records are state records—the highest temperatures ever reliably recorded anywhere in a particular state. The NOAA-based State Climate Extremes Committee (SCEC) does not keep track of monthly state temperature records, but a database maintained by WU weather historian Christopher Burt shows that a number of states appear to have set or tied their all-time record highs for October on either Tuesday or Wednesday. Below are the preliminary new records as compiled by Burt.

Alabama: 105°F at Marion on Oct. 2 and 3 (old record 103°F at Troy on Oct. 5, 1954)
*A reading of 106°F at Jasper on Oct. 3 appears questionable.

Florida: 101°F at Crestview on Oct. 3 (old record 100°F at Molino on Oct. 1, 1904; Orange City on Oct.1 and 2, 1904; and Crestview on Oct. 1, 2019)

Mississippi: 102°F at Meridian on Oct. 2 and 3 (old record 101°F set at same site on Oct. 1, 2019; preceding record of 100°F set at six previous sites on different dates)

Delaware: 98°F at Wilmington on Oct. 2 (old record 97°F at Bridgeville on Oct. 5 and 6, 1941)

New Jersey: 97°F at Millville on Oct. 2 (ties same at Flemington and Tuckertown on Oct. 5, 1941)

New York State: 95°F at John F. Kennedy and LaGuardia airports on Oct. 2 (ties same at Danville on Oct. 2, 1927)

Tennessee: 100°F at Chattanooga on Oct. 2 and 3 (old record 99°F at three previous sites on different dates)

Kentucky: 98°F at Bowling Green and Kenlake Resort on Oct. 2 (ties 98°F set at three previous sites on different dates) .

Maryland : 101°F at Webster Naval Air Field on Oct. 2 (old record 99°F at three locations on different dates)

Washington, D.C.: 98°F on Oct. 2 (old record 96° on Oct. 5, 1941)
