There will be a few more wet, cool days before the weather transitions on Sunday to warm and sunny. The drier conditions have many state officials worried about the wildfire season. Gov. Jay Inslee announced a drought declaration this week, but KNKX weather expert Cliff Mass says things may not be as bad as they seem.

The wet season has returned to Western Washington, with showers and all out rain alternating through early next week, a continuation of the pattern we’ve been seeing for a while.

“But none of that’s going to be that heavy. And the reason is, most of the weather is going into California,” said KNKX weather expert Cliff Mass, who teaches atmospheric sciences at the University of Washington.

There’s a key weather battle that plays out every summer. It determines how warm (or hot) conditions can get in the Puget Sound region. It’s the tug of war between onshore and offshore flow, says KNKX weather expert Cilff Mass.

It’s a prequel to the infamous June Gloom — that dreary period of typical Northwest, in-between weather, with clouds that hang low and persist for weeks without providing any meaningful rain.

KNKX weather expert Cliff Mass says May actually marks the start of the "low cloud season" that dominates in June. And we should expect it to extend from now until mid-July.

Clear blue skies and sunshine got the weekend off to a beautiful start in Western Washington. Both are expected to stick around all day Friday, before shifting to showers Saturday morning.

If you’re tired of all the precipitation that has been raining down on the Northwest since early April, take heart. KNKX weather expert Cliff Mass promises this weekend will be dry and even a bit sunny.

Major April showers are dousing the Pacific Northwest, and they're bringing more than flowers. Environment reporter Bellamy Pailthorp talked with weather expert Cliff Mass, who provided the latest forecast and an update on the water situation in the region following an unusually dry March.

Stay indoors or get out the Gore-Tex this weekend if you’re going outside in Western Washington. KNKX weather expert Cliff Mass says a triple whammy of weather systems will douse the region, providing some relief from our record-dry March and only a few dry periods over the next few days.

“We’re going to have three rain events over the next 72 hours,” Mass said Friday morning. “The drought of March is going to be over.”

Another warm, dry weekend is in the forecast for western Washington, adding to what has been an unusually parched month of March. KNKX weather expert Cliff Mass says he expects this to become the second-driest March ever recorded at Sea-Tac Airport, going all the way back to 1948.

A weather front approaching the Puget Sound region on Friday morning held the promise of precipitation sure to be welcomed by residents suffering from watery eyes, sinus pain, coughs and running noses.

Some folks in the greater Puget Sound region have still been watching the last bits of snow melt in their yards, after record cold hit the region last month.

But it will all be gone for sure this weekend, as KNKX weather expert Cliff Mass says a radical change is underway.

Snow showers mixed with rain on Thursday and Friday were the final hurrah for the cold that's had the Puget Sound region in its grip since early February. KNKX weather expert Cliff Mass says a sunny weekend is in store, with steadily warming temperatures. He says the threat of lowland snow is over.

If you live in Western Washington and sunny, clear blue skies tend to lift your mood, you’re in luck. KNKX weather expert Cliff Mass says temps will be in the mid-40s or higher with plenty of sun and no rain until early next week. He calls this kind of weather “totally boring.”

With temperatures hovering around freezing in places and the snow level dropping, several parts of Western Washington saw snow flurries Friday morning. How much more snow will fall in the coming days and whether it will stick are highly uncertain, says KNKX weather expert Cliff Mass.

Temperatures will hover above freezing for the next few days, allowing accumulated snow and slush to slowly melt in western Washington.

KNKX weather expert Cliff Mass says air that’s cold enough to bring more snow will soon be back. It’s still unclear whether that will actually materialize. But either way, Mass is predicting this February will go down as the coldest on record.

Snow flurries started flying into the greater Seattle region Friday morning a little after 7:30, landing on sidewalks and roadways that were finally clear after the big storm that hit the region on Monday.

But those flurries were just “a teaser,” said KNKX weather expert Cliff Mass, not the big event expected later in the day.

It’s a tricky forecast, as are most that involve lowland snow around Puget Sound, says KNKX weather expert Cliff Mass.

But residents of Western Washington should brace themselves for the coldest temperatures they’ve seen so far this winter, with a serious possibility of the white stuff hitting near sea level in several areas on Sunday and Monday.

Light clouds and blue skies greeted most folks in the Puget Sound region Friday morning, and those conditions were expected to stick around all weekend long and into early next week.

Lots of lovely days are in the forecast, says KNKX weather expert Cliff Mass.

An impressive storm was looming offshore Friday morning, promising to bring significant rain and wind to the Puget Sound region. But KNKX weather expert Cliff Mass says it won’t hit too hard and should give way to a relatively quiet weekend, with plenty of breaks to get outside.

The persistent pattern of stormy weather that caused sweeping power outages in the Northwest and restored our snowpack and water supplies in recent weeks is in the rearview mirror, for now. KNKX weather expert Cliff Mass says it will be dry and mild till the middle of next week. And the sun will break through this weekend.

Blustery, wet weather blanketed the region overnight into Friday. KNKX weather expert Cliff Mass says you can expect the generally stormy pattern to continue for several weeks, despite a break on Saturday.

Rainy weather continues to dominate the forecasts in the Pacific Northwest. A healthy dose of wind enters the picture this weekend too, and it will be strong enough to cause some power outages, says KNKX weather expert Cliff Mass. But all that weather should blow through in time for a relatively dry New Year’s Eve.

Indulging the curiosity of a loved one who wants to learn more about the weather is a great way to show your affection over the holidays, says KNKX weather expert Cliff Mass. And he says it’s one of the most frequent questions he gets.

After an unusually dry and sunny start to the season, fall in the Northwest is getting back to normal.  Earlier this week, Seattle charted the darkest day its skies had registered in three years, as clouds and wet weather blotted out the sun. KNKX weather expert Cliff Mass says the outlook for the week ahead is a smorgasbord of the things we usually get in winter around Western Washington.

A week of sunny skies that capped nearly a month of unusually clear, bright weather for late fall is wrapping today. KNKX weather expert Cliff Mass says the sun will be a bit filtered as a weather front moves in.

An atmospheric river came through the Pacific Northwest last week, dousing the region with enough precipitation to bring accumulated rain levels almost back to normal after an extremely dry start to November. But KNKX weather expert Cliff Mass said the storms were headed southward on Friday, giving California some much-needed rain.

After a string of dry and sunny weekends in greater Puget Sound that had some of us here a bit concerned about the water supply, KNKX weather expert Cliff Mass says don’t worry. He says the normal late November pattern of heavy precipitation has set in and will extend into next week and beyond. It even dusted the mountains with some Thanksgiving snow.

Normally, mid- to late November in the Pacific Northwest is a time to bundle up and get cozy indoors, as the wettest and stormiest weather settles in and provides a stark contrast to the blue skies of late summer and early fall.  But this weekend, similar to last, people in the region can expect a really nice weekend for all manner of outdoor pursuits.

It’s that time of year when seasoned Northwesterners soak up as much sunshine as they can when they can — because the end is near. KNKX weather expert Cliff Mass says the last two weeks of November predictably bring the worst weather of the year.

But this weekend, he says there will be quite a bit of sun. Mass expects many people will get out and enjoy it.

People in the Pacific Northwest experienced wet but weirdly warm weather on Thursday as rain generated by an atmospheric river came through. These plumes of moisture are a classic feature of late fall and winter weather on the West Coast, and are also known around here as "The Pineapple Express" because they originate in the tropics near Hawaii. And they can bring in unseasonably warm temperatures.

The region felt a classic example of it on Thursday, says KNKX weather expert Cliff Mass, who teaches atmospheric sciences at the University of Washington.
