Strong onshore is pumping the cool, moist ocean air in from the Pacific, keeping temps below average and stubborn overcast skies trapped in the Puget Sound basin. Highs struggled to make it out of the 50s on Tuesday, barely cracking 60 degrees at Sea-Tac Airport late in the day. The pattern doesn't change much on Wednesday, and as such, the weather won't either!

Heavy rain, but plenty of shine...it must be April in the Pacific Northwest! The "kitchen sink" Tuesday featured peeks of blue sky and long rounds of gray, which often dropped heavy rain and hail on commuters. Highs again ran a bit chilly, with temperatures topping out just barely above 50 near the metro area. Southwesterly gusts of 35 to 50 mph howled through the region at times, especially near the coast and north of Mukilteo. A dry break ensues on Wednesday, and lasts a whopping 24 to 30 hour

Winter weather has finally walloped the Cascades, with snow totals of one to two feet over the higher peaks in just the last two days. Tonight, the WINTER STORM WARNING continues there, which will account for an additional 8 to 18" of snow through Thursday. This is wonderful news for the ski parks, with most of the terrain now up and running for the season. We'd love to keep this seasonable snow level going...but another warm surge now appears determined to take over for a spell early next week.

Another night, another storm! Spring tried to take the baton today, but winter wrestled it back just in time for the evening commute. As promised, we battled heavy rain, gusty winds, pockets of hail and rumbles of thunder and lightning just when everyone was hitting the highway to head back home. Up in the mountains, this heavy precipitation is translating into more heavy mountain snow, and the WINTER STORM WARNING/WINTER WEATHER ADVISORIES will continue for the Cascades through Saturday morning

The finale of April was sure a looker: blue skies made for a brighter and warmer day, and highs headed up into the low 60s around the Sound, which was near normal for this time of year. However, May Day will be even warmer, with a ridge of high pressure building quickly along the west coast on Thursday. This will keep us clear and will coax in a mild, dry northeasterly breeze, which will push temperatures up into the low to middle 70s around the metro area. Some communities near the foothills or

After days on end of oddly dry and quiet weather, at least things changed up a *touch* on Thursday: a weak disturbance ambled over the top of us, increasing the cloud cover and dropping a few showers from Cape Flattery to Cosmopolis. The drops (and a few stray flurries) were fleeting, few, and far between, but we'll take what we can get! The Olympics and south Cascades will pick up a skiff of fresh snow over the next few hours. It won't be enough to make boost our lean snow pack, but hopefully i

We're heading into early March, and we're running plenty behind on rain and snow this season. Sea-Tac is over 4.5" below the normal since the first of January, and the north and Central Cascades are only checking in with 60 to 70% of the average snowpack. Thankfully, Tuesday's disturbance remedied that a bit, with a solid mid-day soaking from the coast to the eastside foothills. By the evening commute, leftover showers were ping-ponging back and forth with sunbreaks, and highs settled in near 50

As promised, Thursday was kind of a weird one, weatherwise! We started with a surge of warmth in FRONT of the front, as mild southerly winds gave us a boost well into the middle to upper 60s around the Sound by mid-day. The approaching storm upped the humidity, so by Northwest standards, it felt a touch muggy throughout Western Washington before the rain arrived. But arrive it did, and in gusty, blustery fashion, it made for a soggy afternoon commute. The rain was heavy at times, and quickly coo

The commutes were showery, the air was crispy, and the pumpkin spice latte orders were flying out of the coffee shops!

Highs only maxed out in the upper 50s to low 60s around the Sound, which is still on the cool side of normal. The damp weather is welcome, because we are quite behind in terms of our annual rainfall.

March is here--late winter weather. But where is the late winter rain? We are running quite behind the curve for our usual precipitation. Since the first of January, Sea-Tac Airport is over four and a half inches behind normal, as we've only picked up 5.41" of rain so far in 2025. The snowpack is looking lean too, with the Central Cascades region at only 62% of the usual amounts between Stevens and Snoqualmie Passes for this time of year. Time to remedy that!

A quick-moving frontal system will barrel by overnight, giving us a short round of steady rain and blustery wind.
