Snow Showers Likely Overnight

Ten below.

That’s how far from average today’s high temperature of 41 degrees in Seattle was, thanks to a cold area of low pressure traversing the region. (Contrary to popular belief, minus ten isn’t what the wind chill registered today, although with the wind gusting well above 30 mph, it did feel pretty darn cold.) Fortunately, for those of you not digging the chilly temperatures, milder air is on the way—but first, we have to get through another round of snow showers.

Light Snow Accumulations Possible Around Seattle Tomorrow

We’ve danced this dance before, huh?

An early-morning Puget Sound Convergence Zone has brought snow showers, along with spotty accumulations, to areas along the King-Snohomish County line. Since 7 a.m. this morning, snow has fallen off and on in North Seattle, Shoreline, Lynnwood and Bothell—the same cities that see the flakes time and time again, while the rest of the region experiences a cold rain. (Yes, Lynnwood—we’re jealous. How would you like to wake up to a 37-degree rain?)

Weekend Snow Showers Possible for Seattle Area—More Rain First

Weekend Snow Showers Possible for Seattle Area—More Rain First

The rain shadow is gone.

After protecting Seattle from the wet stuff all day Tuesday—we received a meager 0.03” in the rain bucket—the rain-free zone created by dry air flowing down the Olympics retreated to its normal home earlier today. As a result, Sea-Tac Airport received a healthy 0.34” of rain in three hours—ten times what fell yesterday. Makes you wonder how wet it could have been around here had we not been rain-shadowed for 95 percent of yesterday/today’s system…

Rain Shadow for Seattle, Snow Later?

Rain Shadow for Seattle, Snow Later?

After a dry day on Sunday—rumor has it the sun even managed to peek through the overcast skies yesterday afternoon—the rain has returned for today.

Currently, light-to-moderate rain is falling across Puget Sound. As we work our way into the evening hours, that rain will continue to increase, becoming heavy after midnight. Then, just as tomorrow morning’s commute gets underway, a seemingly magical act will take place. The winds up high will shift to the west—and the rain will shut off completely.

All hail the Olympic rain shadow.

Cold and Stormy Presidents’ Day Weekend Looms

After a couple days of relatively benign weather—sunshine, fog, and the occasional raindrop or two—a much more active weather pattern is on tap for the Seattle area, just in time for the holiday weekend.

Scattered light rain showers roaming around the area this evening will dissipate as we head into the overnight hours, with the temperature holding steady in the mid-40s. As we get into Friday morning, we’ll actually see the mercury rise a little bit, as warmer winds in advance of our next rainmaker nudge temperatures up into the lower 50s. The morning commute should be relatively dry, with the greatest chance of some light rain in the South Sound.

Cooler Temperatures the Next Few Days

Cooler Temperatures the Next Few Days

The streak is over.

Friday marked the ninth—and last—consecutive day of above-average temperatures for Seattle, with a high of 55. Unfortunately, Saturday’s persistent cloud cover prevented the streak from reaching double digits, as we only topped out at 48 degrees—two shy of the average high for the day. Regardless, nine back-to-back days of warm weather in mid-winter is pretty impressive, especially in a La Nina year (where temperatures are generally cooler than average).
