Marine Air Is Surging In
After a stream of substantially inwards a higher house normal temperatures, the Northwest's AC is forthwith laid to high, equally cool, marine air pushes into western Washington tonight.
Meteorologists carefully written report the delineate per unit of measurement area departure betwixt the coast (e.g. at Hoquiam) together with Seattle to appraise the situation. When that departure gets to almost iii hPa, a expert force is pretty much guaranteed. Here are the latest numbers:
Hoquiam minus Seattle is forthwith 3.6 hPa.... a guaranteed marine push.
The latest (10 PM) surface observations demonstrate that cool air has pushed into the Strait of Juan de Fuca together with has already moved inland S of the Olympics. Only key Puget Sound is inwards the 70s....and that volition alter rapidly during the adjacent few hours.
The visible satellite icon at vii PM clearly showed depression clouds moving inland from the coast, piece thunderstorms were evident over the Cascades (see below).
The drive of this marine push? The displace of the high delineate per unit of measurement area ridge inland together with the approach of an upper degree trough (see upper level-- 500 hPa- map at v PM today).
Low clouds should last over most of western Washington on Th morning, amongst high temperatures alone reaching the mid-70s. Perfection. And Fri volition last fifty-fifty cooler, amongst highs alone getting to the upper 60s, followed past times a pocket-sized warming over the weekend.
The cooler air volition last welcome.....my trivial domestic dog has non liked the warm weather, preferring to slumber on the flooring rather than inwards her normal chair.
Thursday morning time addition
An interesting facial expression of this marine force is how shallow it is. Here is the fourth dimension acme cross department of temperatures (red lines) together with winds inwards a higher house Sea Tac Airport (time is on x-axis together with acme (in pressure) on the y). The cooling started around 06 UTC (11 AM PDT) together with was pretty much express to below 850 hPa (about 5000 ft). So big cooling close body of body of water level, merely y'all would non honor it at higher elevations.
The visible satellite imagery this morning time shows nearly all of western WA covered inwards depression clouds:
