still cold

by 9:30 last night, it was already back down to -4 and by this morning we were up (a little bit) to 0
good high pressure yesterday meant lots of sun -- i didn't get to check the water tank temp until 9:30, so it probably went somewhat higher than the 44 I read then
because of the brutal cold, I left the electric heater running on low in the gh last night (though it still didn't keep freezing temps from creeping in)
