Morgan - Friday evening
A modest weather system is moving into Western Washington with some precipitation coming in along with it. Fortunately for travelers, this system is moving along at a good clip and will be in and out of the area in less than 24 hours. Still, we will have some weather issues early in the day.
Temperatures as we head into Saturday will not fall nearly as fast and most locations will only reach the freezing mark or below for just a few hours before daybreak Saturday. These milder temperatures as well as the fairly light nature of the forecast snowfall will serve to limit accumulations. The best chance to get a slushy inch of snow through early Saturday morning will be around Hood Canal, southwest Washington, and areas from Pierce County south. Also, the foothills and adjacent locations on the Eastside could get some minor accumulations.
Later on Saturday morning, temperatures slowly warm and we’ll still have precipitation around, especially east of Puget Sound and perhaps across the northern sections of the area. With each passing hour into the day, rain will become more involved in any precipitation, instead of just snow, and accumulation of snow will likely become less and less possible.
By Saturday afternoon and evening, some pockets of cold rain or rain/snow mix will linger, but with little further impact as temperatures will be in the upper 30s to low 40s.
In the mountains, 2-4 inches of snow will fall Saturday.
On Sunday, a few flurries or sprinkles will be around early in the day, but we’ll break out into sunshine. Lows will be in the upper 20s to lower 30s and highs in the 30s to low 40s.
Monday through Wednesday will be dry with highs in the 30s with sunshine. Morning lows could be bitterly cold Monday night into Tuesday morning and again Tuesday night into Wednesday with teens to low 20s to start. There is some disagreement in forecast data as to how cold it will get those mornings, so we’ll be updating the forecast. This has a good chance to be the coldest morning temperatures since the bitter cold blast of January 2024 (though during that time we only had daytime highs in the 20s. We’ll be in the 30s this time around.)
Another chance of snow and rain/snow mix arrives around next Thursday into Friday. We’ll watch that carefully as impacts could be significant, at least for a time before temperatures turn a little milder by next weekend. By next weekend, highs could be back in the 40s but still not to the average or “normal” high, which is currently 50° in Seattle.

A modest weather system is moving into Western Washington tonight with some precipitation coming in along with it. Fortunately for travelers, this system is moving along at a good clip and will be in and out of the area in less than 24 hours. Still, we will have some weather issues early in the day.
Showers of rain and snow this evening will mainly affect the coast and Olympic Peninsula with some light snow and rain/snow mix. In the interior of Western Washington, including Puget Sound, we’ll have precipitation starting up here and there after midnight into the morning hours of Saturday.

Frankie - Friday afternoon
Blue skies and sunshine are a pleasant sight this afternoon. There’s still some remnants of yesterday’s snow showers north of King county.
This afternoon will remain dry and mostly clear, but this evening cloud cover will increase ahead of our next weather system. A trough of low pressure overhead will move further in the Pacific Northwest and behind it comes our next round of showers.
Right now, computer models are showing mostly snow but there will be a mix of rain, snow, and a little of both. Precipitation type and accumulation will vary by time, location, and temperature. However, I will say I do expect flurries and wet snow to fall as far north as Whatcom county and as far south as Skamania county.
With overnight/morning lows in the 20s and low 30s, snow will be favored during this time frame but this round of snow does look more conservative in amount compared to yesterday and earlier this week.
NBM probabilities suggest 20-30% chance of Puget Sound lowlands seeing an inch of snow. Chances increase up to 40-60% with the presence of easterly winds around Hood Canal. NWS have not issued any winter weather advisories, watches, or warnings yet.
In the mountains and passes more snow is expected of course (approximately 2-4″) but according to NWS conditions remain below any advisory criteria.
Nick - Friday morning
Happy Friday! We are off to a very cold and dry start this morning with temps ranging from the low-20s to the low-30s. Watch out for ice this morning, especially in areas that had snow yesterday. Some lingering clouds have kept our temps up higher than forecast in the South Sound, but just about every observation station is at or below freezing. The Cold Weather Advisory will expire at 10 a.m., but please be careful when you go out. Black ice is super dangerous.
We’ll stay dry throughout the day today with increasing clouds and then some showers pushing inland either late tonight or overnight. As the moisture moves inland into very late Friday night and Saturday morning, the precipitation type will be either snow or wet snow, though there could be some rain/snow mix right on the large bodies of water. This system will push the snow into the Cascades by daybreak Saturday, but some snow showers will linger into very early Saturday afternoon.
The greatest chance of accumulation comes in the overnight hours into Saturday morning and will likely be in the 1-2 inch range for most. However, there will likely be some isolated spots with higher amounts, with the best shot of accumulation more than two inches in the South Sound away from the water. The computer models are having a hard time pinpointing exact locations for accumulation, but in general, the more southern locations have a better shot for snow to build up.
Flurries will linger into Saturday afternoon and Saturday night with some spots of sunshine. Sunday will be much drier but there will be a few snow/wet snow and rain showers around with patchy morning icy spots. The same is forecast for Monday through Wednesday of next week. No organized weather systems are expected but a few snowflakes could flutter from time to time with weak disturbances passing through. We could see some moisture return by Thursday which would include some wintry precipitation. Of course, it’s too soon for more than that at this point.
The cold remains through next week with highs in the 30s and lows in the upper teens to mid-20s.
Don’t expect any moderating of these very cold temperatures until at least Feb. 15 — that’s next weekend.
Morgan - Thursday evening
Clear skies tonight will allow temperatures to plummet after dark. A few spots, like Seattle at 25 degrees in the morning, will have the coldest start of the winter so far. Some upper teens are likely in Western Whatcom County, some of the colder North Sound areas like Granite Falls and Arlington, and around Mason County. Elsewhere, it’ll be in the lower 20s to start.
Moisture around will refreeze on untreated surfaces overnight, so drivers beware of this threat early and walkers should be careful on sidewalks.
Highs tomorrow will be in the 30s Seattle north and 40s south.
Clouds will increase late with some spotty rain/snow showers at the coast by mid-evening. As the moisture moves inland into very late Friday night and Saturday morning, the precipitation type will be mainly snow, though there could be some rain/snow mix right on the large bodies of water.
This system will be pushing the snow into the Cascades by daybreak Saturday but some snow showers will linger around into very early Saturday afternoon.
The greatest chance of accumulation comes in the overnight hours into Saturday morning and will likely be in the 1-2 inch range for most. However, there will likely be some isolated spots with higher amounts, with the best shot of accumulation more than two inches in the South Sound away from the water.
Flurries will linger into Saturday afternoon and Saturday night with some spots of sunshine. Sunday will be mainly dry with a few flurries around with patchy morning icy spots. Same forecast Monday through Wednesday of next week. No organized weather systems are expected but a few snowflakes could flutter from time to time with weak disturbances passing through.
The cold remains through next week with highs in the 30s and lows in the upper teens to mid 20s. There are signs we could have some more snow or rain/snow chances toward the end of next week but we’ll monitor that potential.
Don’t expect any moderating of these very cold temperatures until at least Feb. 15 — that’s next weekend.
Nick - Thursday morning
Happy Thursday! We have a narrow band of snow showers still falling over the area this morning with a huge mix of conditions. Around Tacoma and Olympia, it is mostly dry with temps in the low to mid-30s. Around White Center north, it’s snowing with a heavy wet snow with temps around 31-35°. That snow extends into Snohomish County as well with temps around 31-32°. That means you could run into some icy and slick roads in the South Sound, some snow, slush, ice and messy conditions around Seattle and the same extending into Snohomish County. Temps are all over the place because we have north wind from the border to about Snohomish County with south wind around Seattle south. That interaction of wind, creating some snow banding, and temps will keep some showers in play for the next few hours. In fact, another 1-2″ could fall this morning before we see the snow showers taper off late-morning and into the afternoon. I can tell you from my drive in this morning, it was very slushy and slippery with standing water, some ice and slush all over.
By about mid-day we should be much drier with a few lingering showers here and there. Temps will warm into the upper-30s and lower-40s with some sunbreaks this afternoon.
With mainly clear skies, the coldest night since January 2024 is likely to start Friday with a Cold Weather Advisory in effect for morning lows in the teens in the colder spots to the low to mid 20s in the cities of the Sound. Highs on Friday could approach 40 as another weather system moves in. This will produce some light to moderate snow into late Friday night and early Saturday before a drying trend. Travel could be difficult again Saturday morning.
Drier weather is probable into later Saturday and Sunday but we can’t say for sure there won’t be a snow or mixed precipitation shower at times. Same into early next week.
It appears we will be much colder than average until at least the end of next week, possibly beyond.
Morgan - Wednesday night
Following an evening of hail and snow showers in King and Snohomish County -- and even a report of a waterspout over Puget Sound -- attention turns to more chances for snow later this evening and tonight.
Through early Thursday morning, the best chances for snow accumulation of 1-3″ with isolated higher amounts looks to be in the central and north Sound, across parts of King, Kitsap, Snohomish and Island counties. Locations nearer the Cascades will also be favored for snow, as well as west of Puget Sound along Hood Canal and west of Olympia.
Be very careful driving overnight as falling temperatures below freezing will also bring the chance of patchy ice.
Across the far south (Thurston/Lewis counties), the coast, and north interior, the chances of significant snow is a little lower with the exception of some heavier snow in western Whatcom County and the Port Angeles area of a couple inches. Still, there will be some accumulations.
Snowfall will likely be lingering around the Central Sound into the morning hours before fading toward midday. We’ll have some afternoon sunshine with highs in the 30s.
With mainly clear skies, the coldest night since January 2024 is likely to start Friday with a Cold Weather Advisory in effect for morning lows in the teens in the colder spots to the low to mid 20s in the cities of the Sound. Highs on Friday could approach 40 as another weather system moves in. This will produce some light to moderate snow into late Friday night and early Saturday before a drying trend. Travel could be difficult again Saturday morning.
