The WSDOT snow study plot near The Summit at Snoqualmie is adorned with all sorts of gauges and measuring equipment to monitor snowpack and avalanche danger.

The criteria needed came together this week, resulting in the semi-unusual frozen phenomenon called "hair ice" showing up around the Puget Sound region.

Experts believe a Mount Rainier eruption would post a grave threat to millions who live in the southern and eastern sections of the Seattle metropolitan area.

La Nina is the opposing end of the spectrum from El Nino, an oscillation between cooler and warmer than normal waters in the equatorial Pacific Ocean.

Here's a look at how the Northwest Avalanche Center's team of forecasters determines the daily risk of avalanches in Washington's Cascades.

The National Weather Service predicts El Niño conditions to persist through the upcoming spring, and that changes what we can expect this winter in the PNW.

It is 95% certain that El Niño will occur for January 2024 through February and March 2024. There is a 71% probability it will be classified as a strong one.

When nature imitates art...or is it the other way around?

Washington State Department of Transportation (WSDOT) officials are busy monitoring the roads at Snoqualmie and Stevens Passes for the upcoming snowfall.

Outdoor recreation enthusiasts know the adage, "There's no such thing as bad weather, just bad clothing."

This Valentines’ Day the sun has been bright, we can ignore the radar for a bit and look at the almanac.

Winter is still very much in play here in the Pacific Northwest, as demonstrated by the formation of fascinating ice spikes around Puget Sound this week.

La Niña brings cooler than normal and wetter than normal winter weather for the Pacific Northwest...usually.

When an atmospheric river is added to a frontal system, a long list of dangers are created for the west coast. Here are some examples from the incoming storm.

In recent years, our gusty mountain breezes have become known as "Cascadia winds."

Western Washington weather never ceases to amaze! Our autumns are typically fast, and our springs slow to show. The year 2022 was no different.

The Convergence Zone (also sometimes abbreviated 'PSCZ') is one of the more fascinating weather phenomena in the Pacific Northwest.Weather 101 Answer:Northwest winds in the upper atmosphere become split by the Olympic Mountains, then re-converge over Puget

So, you thought you'd stay informed on the crazy weather this winter by friending or following a meteorologist on Twitter.And then comes the snow or storm forecasts, and Tweets become filled with cryptic terms and maps that look like some...

There are two different wind events that are most common around Western Washington. There's a pattern that brings strong easterly winds to the Cascade foothills, and another that brings strong winds to the Western Washington lowlands.Lowland Wind EventsWin

SEATTLE -- Hurricanes have the Saffir-Simpson Scale ("Category 5"), tornadoes have the Enhanced Fujita Scale ("EF-3") but now the West Coast has a storm scale of our own with a recent introduction of a new rating system for "atmospheric rivers"...

This chart will show how many times it has rained in Seattle on any given day over the past 125 years. Period of record: Jan. 1, 1894 - Nov. 19, 2019. Combination of Seattle-Tacoma Airport (1945-present) and Downtown Federal Building...

Well, sort of.Seattle ranks behind a lot of cities when it comes to annual rainfall totals. Chicago, Dallas, and Miami, among others, all get more rain per year than Seattle's 37 inches.But that's because while it indeed rains a lot...

Marine pushes are the summertime occurrences that bring our steady diet of morning fog. It also contributes to our natural air conditioning.On most days in the summertime, there is higher pressure that sits offshore from Western Washington, and lower press...

This is kind of tricky. Even though showers are indeed rain, theres a subtle but important distinction between the two as far as weather forecasts go.When we call for Rain as in, Rain at Times, a rainy day, Occasional...

There are two main types of fog, and the Northwest gets both varieties. And they both are directly related to the dew point.The dew point is the temperature at which the air becomes 100% saturated. At that point, the air...

The thermal trough is responsible for almost all of our heat waves in the summertime. A lot of times, we associate low pressure with stormy, rainy weather. But intense heat can also cause low pressure.In the hot desert, you...

This is a trick question. There really isn't much of a difference. They all mean the sky is part clear, and part cloudy. It just gives us a larger vocabulary to work with.Although most of the time, we'll tend to...

A reported "freezing" level is the altitude where it is forecasted to remain below 32 degrees for the entire forecasted time period.

A tsunami is a large wave that can come ashore at heights of over 100 feet tall.

Most of the time, what you're seeing is not simply a photograph from space.

It's a long story...

This happens when we get a strong area of high pressure in Eastern Washington and a storm tracking up the coast.

It all has to do with air, and how light gets reflected.

On average, Seattle gets about 25 days a year that go over 80 degrees.

Scientists long ago realized that atmospheric pressure drops as your altitude increases
