Those big fat snowflakes falling in Boise this morning are a local phenomenon, thanks to the stubborn inversion that has been parked over the Treasure Valley all week long.

If you were at Bogus Basin Mountain Resort at 10 a.m., it was a sunny, cold, and clear morning. Dip under 5,800 feet, however, and it’s a grey snow flurry deal, with snow falling intermittingly all morning long.

The National Weather Service measured just a trace of snow at the Boise Airport as of 10 a.m. Wednesday. Warmer air is trapping colder and moister air close to the valley floor, which is why we are getting snowed on.

Wednesday’s snowfall didn’t really cause any traffic issues and didn’t really stick to the street.

That same inversion is also helping us stay warmer overnight. If those clouds were not over the Treasure Valley, early morning temperatures might have dipped below the 0 degree mark over the last few days, according to National Weather Service reports. Instead, we have been in the teens.

Treasure Valley residents should expect it to be cloudy and cold through the end of the work week, with estimated high temperatures in the mid 20s and lows in the mid teens. If it snows, it will be like Wednesday morning, with slight flurries. Expect the sun to return by the weekend, with highs in the low 30s, according to National Weather Service reports.
