Feeling a bit under pressure?
Atmospheric pressure reached a two-year high at Sea-Tac Airport on Friday, according to the National Weather Service.
The pressure, expressed by millibars, reached 1038 at 4 a.m. The standard pressure at sea level is 1013 millibars.
The Weather Service said it’s the highest recorded since Dec. 30, 2014.
It’s part of a weeklong rise of the barometer. Pressure has risen 52 millibars in the past week.
“An unusually large swing for us,” the agency said.
Atmospheric pressure refers to the weight of the atmosphere above us. When it changes, especially rapidly, it usually signals a change in weather.
When pressure drops, it can mean stormy weather is on its way. When it goes up, break out the sunscreen.
And that’s the forecast for Western Washington on Saturday (Jan. 28).
The Weather Service is calling for sunshine and a high of 49 degrees with a low of 34.
On Sunday, a slight chance of rain will return, but the high will remain at 49.
Monday will be partly sunny.
Thank you, high pressure.
“Queue the Queen & Bowie,” the Weather Service said in a tweet.
