This is that switch in the bathroom after I drop a bomb (uh oh, deletion soon)

My crappy thermo is reading 9F, but the local meso sites are in the 10 to 11F range, Nice snowmaking wx

I wish WaWa had a station on the summit that we could access. I know they have thermometers, etc. up there, but not online

We all have that one, I sit in kind of a shelterd valley here, I am only at 231' elevation, But i am surrounded by some higher elevation around 700'

To clarify, I did mean with a radiation shield of some kind - whether a passive or actively aspirated variety. From the Office of the Federal Meteorological Coordinator with regards to siting of co-op stations:

Temperature sensor siting: The sensor should be mounted 5 feet +/- 1 foot above the ground. The ground over which the shelter [radiation] is located should be typical of the surrounding area. A level, open clearing is desirable so the thermometers are freely ventilated by air flow. Do not install the sensor on a steep slope or in a sheltered hollow unless it is typical of the area or unless data from that type of site are desired. When possible, the shelter should be no closer than four times the height of any obstruction (tree, fence, building, etc.). The sensor should be at least 100 feet from any paved or concrete surface.

That's laughable when it comes to some official climo stations....Honolulu is one that I can think of off the top of my head.

I agree that the shelter needs to be in the open if possible, a FARS has been shown to be much more accurate than even traditional shelters such as the cotton/stevenson. Also the radiation shield if it's too small (my case in Union) can have daytime issues but that's not addressed by these guidelines.

Well, to be fair, the official climo stations are there for air traffic safety, not for representative climatological record keeping. People seem to forget that, and it's really an NWS issue. Nonetheless, temperature sensors and their shelters should be in the open which results in full sun exposure.

13.6...it's past the cold threshhold where the downstairs woodstove can't keep the upstairs at 67 so the oil heat kicks in...and i can't walk around in just socks cause the could floors make the bottoms of my feet go numb...

8 here. I was just noticing the same thing here with my downstairs woodstove not quite getting the job done. Luckily I have one upstairs too. First two stove night of the winter for me.
