Following one of the snowiest Februarys on record, Seattle is in for another rare weather event this coming week.
An area of high pressure is expected to park itself over the Interior Northwest and Pacific Canada, promoting a surge of mild, dry air to the coast.
This setup will allow temperatures to soar to unusually high levels in the Pacific Northwest, mainly over coastal portions of Washington and northwestern Oregon.
The temperature could reach 60 degrees Fahrenheit in Vancouver this week, which has not occurred since Oct. 26, 2018. In Seattle, a string of rare 70-plus-degree March days are in the forecast.
Temperatures at Seattle-Tacoma Airport have only exceeded this milestone 17 times in the 75 years that records have been kept. Additionally, only six of these have occurred before the first day of spring.
After kissing 70 degrees on Monday, thermometers are expected to rise into the low 70s F on Tuesday and Wednesday. New daily record-high temperatures could be broken each of the three days.
Combined with sunshine and only a light breeze, it will feel a few degrees warmer than it actually is.
Bars and restaurants will benefit from offering outdoor seating options through midweek as residents go out of their way to enjoy the pleasant weather.
Those hoping to take advantage of the warmth by heading out to hike, bike or otherwise enjoy the wilderness of the Pacific Northwest should take care around bodies of water. Increased snowmelt means rivers will be running high and fast, with water temperatures still dangerously low.
Some river flooding and ice jam concerns may arise for this reason, as well.

The sun angle is the same now as it is in September, so anyone heading outside should be sure to take along the sunscreen.
The mornings will feel especially mild with low temperatures near 50 F, a trend that will continue through the end of the week even as cooler daytime weather returns.
A storm system moving into California will disrupt the mild breeze in the Pacific Northwest, preventing temperatures from rising past the mid-60s F beginning on Thursday. Associated rainfall is expected to arrive this weekend as high temperatures fall into the 50s F.
