A recently released study finds Idaho is one of the worst states for driving in bad weather. Snow, not rain, is the problem.

It’s still technically fall, but with dustings of snow already falling in some parts of the state, winter is definitely coming. A report from Safewise – a website that reviews and compares safety products – finds Idaho is one of the most dangerous places to drive in snow.

If you thought it was exceptionally cold this weekend in the Treasure Valley, you'd be right. The frigid temperatures were the coldest in three years.

The National Weather Service says the Boise Airport hit zero degrees Sunday morning at precisely 8 a.m. While the mercury only stayed there for a few minutes, it was long enough to break a three-year streak of temperatures.

Tuesday’s snowfall was just a preview of events to come. Another storm is moving into the Treasure Valley, which could disrupt traffic Thursday afternoon.

National Weather Service Meteorologist Elizabeth Padian  says there’s a warm front moving in from the Pacific Coast.

“With the cold air that we had this morning and today trapped here in the Valley and the Snake River Plain, that’s going to allow that warm air from the warm front to override over that colder air, produce precipitation and it will be in the form of snow here in the Valley,” says Padian.

Last month was the warmest February ever recorded in Boise.

The National Weather Service says the city broke records for average high temperatures, warmest average low temperatures and warmest average temperature. The region also received more rain than usual.

The average high temperature in Boise was 53.2 degrees. That broke a record set in 1992 by a half degree. The previous record for average lows was set in 1983. The previous record for warmest average temperature in a February was set in 1963.

Such records have been kept in Boise since 1940.

So far, February is turning out to be an unusually warm month in southern Idaho. According to the National Weather Service (NWS), temperatures for the first two weeks of the month have been 10 degrees above normal and have included two record-breaking high temperatures.

NWS Boise hydrologist Troy Lindquist says a wet and cooler spring would help the situation, and an early mountain snowmelt makes this year's water picture less sustainable.

Treasure Valley residents still dealing with the aftermath of last week's record-setting snowfall now have an inversion on their hands, too.

The National Weather Service in Boise says the inversion set up Sunday. Meteorologist Bill Wojcik says it's likely to last through Saturday when winds from a new system disrupt the layering of warm air over cold. He says the inversion - the first of the season - reaches 10,000 feet into the atmosphere.
