How warm is the house?
Never been in double digit -Fahr. temps myself. Big wussy, fine.
My state's record is -54. How's that?

I generally keep whatever room I'm in for a while at 68 F and all the rest of the house at 55 to 58 F.
I've definitely never experienced -54. I expect that would cause serious damage to a lot of things around here since nothing is expected to have to survive that. The lowest we get is -25 to -30 for a few days every 3 or 4 years-- nothing like the true arctic areas.

So when the water stops flowing, that's a function of outside temps as opposed to warming inside pipes?

Oh, yeah, I see what you were asking. The trouble spots in my house for frozen pipes aren't much affected by the temperature of the interior. It's a combination of outside wind speed/direction/duration and poor circulation in some tight pipe areas along outside walls that does me in. As I've identified trouble spots over the past 5 years I can usually solve a problem with a fan rather than a heat source. I can still keep the adjoining room in the 50's, but if that air gets blown into the right place, that's all that matters. If I don't use a fan to circulate to the trouble spots, it doesn't matter how hot the adjoining room gets, it still won't prevent a freeze.
I've been extremely lucky so far in that my frozen pipe episodes each year have all eventually thawed with no damage. One burst pipe in the wrong spot can cause thousands of dollars of damage.
There must be some kind of formula for this, something like:
× = W(T1-T2)/f.h+a²
(W being exterior wind speed, T1 exterior temp, T2 interior temp, f fan speed, h direction of interior heat source, and c area of interior heated wall) and x could be something like "human survivability threshold".
but then again, i'm crap at algebra, just having fun.

Don't forget to factor in the size and distribution frequency of gaps in my old crappy exterior siding that lets sustained wind penetrate into the wall interiors in the first place.

ok, now modified to × = W.t+s(T1-T2)/f.h+a² where t equals time (duration of exterior windspeed) and s the surface area of wind coming in. I have thought of factoring in the speed of light squared, but no need at this point.

Right-- that doesn't come into play until the heating bill is calculated.

Where were you living in 1994? I don't know where you live exactly, but I've got this fanciful image of you as a prof. at MTU. In '94, temps in the Houghton area got below -40, and I think as far down as -50, but I'm not positive. My brother was attending Tech at the time. I was still trolling below the bridge and it only got into the -20s down here.

I didn't realize it had gotten that cold in the Keweenaw. I was in Ann Arbor in 1994-- I lived there from 1987 thru 1998. My U.P. living has only been at the east end in Chippewa County, currently in Pickford.
I see one source that lists Michigan's all-time low as (-51) at Vanderbilt (just a little north of Gaylord), on February 9, 1994. I don't specifically recall that cold episode, but in Ann Arbor it was only down to (-13) that night.
However, only 3 weeks earlier was one of the most widespread bitter cold waves of the 20th century (though 1996 was even worse), lasting almost a week. Ann Arbor was down to (-22) on January 19, 1994, with 2 days earlier that week at (-16). The Soo got down to (-29) that week and had 3 of the next 4 nights all below (-20). That cold front extended all the way down to Texas, which had some temps below (-20).
I was in Minneapolis once at -20F. The hotel I was in directed me to a restaurant "200 yards" away. Halfway there I wanted to lay down and take a nap. It was so cold I didn't really feel it, but it just shut my body down.

Yeah, the mountain states can really push down the temp at the high elevations. Nothing like that around here-- I'm at an elevation of about 600 feet.
I think the mountainous terrain has everything to do with it. I remember from a geography course I took, Mountains, a graphic of cold temps in the Alps. The cold air being denser would flow and pool until the coldest air settled into local pockets. Higher up it was cold but in those pockets at lower elevations it could be a few 10s of degrees colder. Very frigid.
It's past noon and it just got up to zero degrees F (-18 C). Last night finally bottomed out at (-17)F [(-27)C] at my house. But the water is still flowing in my house pipes. Yay!!!!
