City-Data is far more than forums. Click on City-Data.com at the top left of this page. Type in Idaho Falls, Idaho in the search box. Very extensive information on the city, including weather, will appear.

The winters here are sunnier than in NID or the Treasure Valley because I.F. is breezier due to its location, but the daylight hours are shorter here all over the state than they are in more southerly areas.

We don't have the lake effect cloudiness NID tends to get, and I.F. doesn't get the temp inversions as often as Boise does. Being located on the western slope of the Rockies and slightly elevated above the Arco plain helps I.F. out a little when it comes to sun in the winter.

But our sunniest days are most often our coldest. Idaho Falls is always a few degrees colder than Pocatello, and can be much colder than Boise or CDA. After a big storm, the temps often plummet way down, and that's when the sky clears and the sun really shines. -10 is still damned cold, even in blinding sunlight.

The reason for the breeze is due to the prevailing winds. It comes from the southwest- usually from the N. California/S. Oregon coast, losing moisture as it moves inland, and when it hits the Rockies, tends to form a hooked shape right over this area as the mountains turn the winds. In strong winds, the hook disappears, and during every winter there are always some Arctic winds that come down from the north that will overcome the coastal wind.

As often as not, the big storms tend to blow through here, and drop most of their snow on the mountains or eastward as they move onto the Great Plains. I.F. is just on the edge of many of them if they're coming from the coast, but from the north, we can get the full blast of a big storm, and the skies will be dark for days on end.

Sometimes that makes a big difference in the winter, sometimes not. There will be lots of very overcast days here every winter. If there are more sunny days than cloudy days, we're headed for a drought the following summer.

Around the winter solstice we have only about 8 hours of sunlight, so from mid-December to mid-February, there's always a lot of darkness. February to March is almost always mostly overcast and grey.
