I know the lay of the land has a lot to do with temperature. Death Valley in southeast California is famously hot because of the way the mountains sit (I've worked in Death Valley NP several years ago). The sun hits the valley floor and the mountains on the west and east sides of the valley. The rock of the mountains is dark and this sets up an inversion layer over the valley creating a greenhouse effect. Summer time temperatures often reach 130 degrees or more (into the 50's C).The Grand Canyon has the same problem. The canyon has a wide outer (or upper) canyon and a narrow inner canyon. The rock making up the inner canyon is very dark and very hard. The sun heats it quickly leading to very high temperature at the level of the river.
Your model is 12hr dependent. You only refer to the daytime in these places.At Night you need to cover up from the cold or freezing it varies in records.

In the Sonora or Mojave you can have a daytime temperature of well over 120 degrees F while dropping below freezing at night. This happens because there is so little water in the air, all the heat escapes into space as soon as the sun goes down.In Death Valley, however, the inversion layer remains stable holding in the heat. In the summer it may be over 100 degrees even at night for weeks and weeks.
