The temperature at Sea-Tac hit 89 degrees on Monday - the warmest April day in Seattle history since records began in 1894.

The previous record high for April 18 was 77. The warmest day in April was 85. That record was set in 1976.

The National Weather Service said Bellingham and Olympia had their warmest April days on record as well, at 83 degrees and 88 degrees respectively. Several other sites in the central Puget Sound area experienced temperatures in the 90s.

"A strong ridge of high pressure continues to strengthen and build into western Washington. With the ridge aloft and offshore winds, temperatures will heat up even more over the next couple of days," said KING 5 Meteorologist Rich Marriott.

Sunday's high of 80 beat the old record of 74, set in 1983.

The National Weather Service says Seattle should see two back-to-back highs above 80 on Monday and Tuesday and that is rare. Since weather records started in the 1890s this has only happened twice in April: April 23 and 24, 1905, and April 29 and 30, 1976.

The warmest day in April on record in Seattle is 85 degrees which has happened four times - April 30, 1976; April 14, 1926; April 24, 1905 and April 16, 1897.

We'll see some cooling on Wednesday, with temperatures in the upper 60s.

Thursday and Friday will bring clouds and some showers.
