Seattle to see 'warmest day of the year' so far on May Day

Thursday could be Seattle’s warmest day of the year so far, with lots of sunshine and high temperatures soaring into the mid-70s.

A ridge of high pressure over the Pacific Northwest will keep the area warm and dry with clear skies. Temperatures will be 10 to 15 degrees warmer than Wednesday with light offshore winds.

Big picture view:

As the ridge shifts east on Friday, it will open the door for a weak frontal system to bring more clouds by Friday afternoon and light rain showers from Friday night into Saturday. 

Rainfall amounts will be light, with only a few hundredths of an inch expected.

Behind the cold front there will be a much cooler air mass, bringing high temperatures back down into the mid 50s on Saturday. We should see a mix of sun, clouds and light showers possible in the first half of the day.

What's next:

The cooler weather will be short-lived as high pressure builds in again early next week, bringing sunshine and warmer temperatures.

In a typical May in Seattle, we see less rain and average high temperatures warming close to 70 degrees by the end of the month. Storms also become less frequent and mountain snow ends.
