That 70s Show

That 70's Show airs today, but it might not be available from your cable provider.

For example, you might want to avoid going near the Great Salt Lake.  The lake is quite cold right now as illustrated by temperatures from 4 PM yesterday afternoon.  While it was 67ºF at the Salt Lake City airport, it was only 54ºF at the Saltair marina, 53ºF at Hat Island, and 51ºF at Gunnison Island.

That's an impressively cold airmass sitting over the lake and it will be there today too.

Another cool spot was the Cache Valley where the high at the Logan Airport only reached 50ºF.  The issue there is snow cover, as can be seen in yesterday afternoon's MODIS image.

They even had some fog yesterday morning and this morning, which can just be made out along the valley floor in this Utah State webcam image.

All of this provides a good example of how the state of the land and lake surfaces can affect the local microclimate.  Today I'll stick to the east bench, where That 70s Show will provide an episode worthy of an Emmy.

  1. I noticed a nice shallow polluted layer right over the south end of the lake yesterday afternoon. Makes sense.
