Snow is coming to southern Idaho, lots of it. The National Weather Service says a “significant snowfall event” will start Thursday night and last through Saturday.

The snow comes from a combination of moisture from the Pacific and an upper level low pressure system from Alaska. It will bring prolonged snowfall, which could mean substantial snow totals in the mountains.  NWS has issued a Winter Weather Advisory from the Oregon border East to Twin Falls, Idaho.

Here are the latest projected snow totals from the National Weather Service:

The National Weather Service is seeking input from the public on new language it’s considering for weather alerts.  Traditionally, forecasters use words like “warning”, “watch” and “advisory”.  But not everyone understands exactly what each term means. 

So 26 Weather Service offices across the country have started a pilot program to use some new language that explains in greater detail what weather is being predicted. The program got underway earlier this month.

NW Skiers Bank On Early Forecasts Being Wrong

A light dusting of snow fell on Oct. 2 at Schweitzer outside of Sandpoint, Idaho

Weather forecasters say the current dry spell in the Northwest may turn into a dry winter. But the region’s ski areas aren’t buying it.

John Livingston is the chief meteorologist at the National Weather Service in Spokane. He says the key to the Northwest’s winter lies in ocean surface temperatures between South America and Indonesia. That’s where patterns are developing that seem to point to a warmer “El Nino” year. “It probably means maybe less snow that we would normally expect in the mountains and then definitely less snow in the valleys with the warmer temperatures.”

Boise Radar Down This Week For Upgrades

National Weather Service

Boise will be without radar service for most of this week, but local forecasters say it’s for good reason.  The radar unit that serves the area will be offline for about five days as part of an upgrade. 

Jay Breidenbach is with the National Weather Service office in Boise.  He says radar works by sending out energy and then measuring it once it bounces off precipitation.  Right now, the Boise radar sends that information out on a one-dimensional plane.  After the upgrade, it will do so in two dimensions.

Sunday saw record high temperatures for much of southwest Idaho and eastern Oregon. In Boise it got to 91 degrees. That unusual heat brings a chance of thunderstorms for much of this week. But the temperature won’t stay at record levels long. Later in the week highs will likely drop to the 50s. 

Jay Briendenbach, the Warning Coordination Meteorologist at NOAA's National Weather Service Office in Boise, says a system of high pressure ridges and troughs is circulating hot and cold air around the country quickly.
