Nights are still really cold (-30s), but we're getting a lot of sun during the day, so it warms up to tolerable temps. Sounds like you're having an incredibly mild winter for WY aren't you?
It does make a big difference when the sun is shining.
It seems mild to me compared to what we've seen in the recent past, but we haven't been here a really long time (got here in spring 2016). Old-timers keep saying to look out for March and April. Guess time will tell!
