I just got back from a short trip to Caliente, Nevada. The weather was looking good when I headed down there, with temperatures predicted to be slightly lower than average, especially if clouds like these stayed around. This photo is from the early evening of the day I arrived.
Caliente is a railroad town. Its mission-style railroad station is now being used for city offices, library, and other civic-type functions. This photo looks south down the railroad tracks, and shows the Boxcar Museum, painted bright red-orange, beyond the railroad depot. Supposedly "officials at the depot frown at people crossing the tracks" to get to the station, but I was assured by someone at the Shady Motel that it was okay, although I didn't see anyone else doing it.
Nevada Historical Marker 249 is on the north side of the railroad depot. Although the sign is stamped 248, apparently two were marked 248, and this one is called 249 on the official list. Text is here.
By the morning of the first field day, thick smoke had moved into the area, supposedly from big fires in Utah. Colors were consequently a little yellowish to reddish, and a bit dulled. You can see an anemometer and some other equipment behind the lampost and to the right of the tree, on the northwest corner of the walkway surrounding the railroad depot.
The anemometer is part of the Caliente Community Environmental Monitoring Program (CEMP) weather station. The only place I could find readouts for this CEMP station was at the Weather Underground. All other online weather reports for Caliente appear to be extrapolations from the usually hotter cities of St. George and Las Vegas.
The main readout panel shows a typical early morning temperature of 58° F (about 14° C).
Temperatures after daily field excursions were usually in the 93° to 95° F range (about 34° to 35° C). That was hot enough for me!
This is a sunset photo, taken in the evening after the first field day, with most of the old main part of town in the lower right. Smoke was thick through the first field day and through the afternoon of the second field day, when the skies cleared and views improved.
On the evening after my second day in the field, smoke moved in again, apparently from the east.
The sun looked like this in the early morning on the day I left, red from the smoke.

Note: As pointed out by @FlorianBoyd, the Kelso Train Station is similar to the Caliente Depot, and is also on the same Union Pacific rail line.
Update: DRI has a map of all their CEMP weather stations here, as pointed out by ChrisM in the comments.
