I "accidentally" found a cold air sink last night/this morning; this time in a sink east of Twin Lakes in the Flat Tops Wilderness of Colorado. I set up the tent in the sink it case it got windy since there was only sparse tree cover around and the only other group at the lake took the campsite with tree shelter. The elevation of the campsite was ~11,030 feet. I took a recording min/max themometer. When I went to bed, it was 23F. By midnight it had dropped to 14F and the overnight low was 6F. That's pretty cold considering the temperature wasn't recorded during a cold snap and that it is early September. I wonder what the winter temperatures would be there?

OK, it's time to revist this thread again!

The benches get more snow, but are also warmer at night and much sunnier. On the coldest nights, it can be up to 15 degrees warmer on the benches. Plus the benches had more firewood available.

In the Salt Lake Valley it is said that the Native Americans would migrate to the benches in the winter in order to avoid the fog on the valley floor.

Fields Oregon appears to be significantly drier than Rome though.

An almanac I have from the 1990s says that the driest weather station in Washington is Priest Lake Dam and lists the driest station in Oregon as Rome.

Interestingly, most of the West Slope had a warm November with +2 to +3 anomalies.

After an exciting October, November weather in Colorado has been incredibly boring.

Nothing but blue skies and sunshine in Western Colorado.

It does seem a bit cold for the location (nearby Big Piney is usually colder and hit "only" -26), but it could be possible. If it is valid, the reading is incredible and is almost as cold as January's record.

One of the more impressive records was Kodachrome Basin Utah at -7. This beats the old October record by 17 degrees. It is also 8 degrees colder than the November record. November has never dropped to zero or below at the weather station.

The breeze picked up at night so the temperature didn't drop below -12 at the official station. It was still the October record though.

Apparently the low yesterday was -46.1.

Of note, the November record low for Randolph is -21.
