A weak front off the Oregon coast will usher in an increase in clouds to the Portland metro area with some chance for showers and light drizzle in the morning. The coast will see spotty rain for sure. But once the cloud cover moves east Portland should see mostly sunny skies and a high of 75 for Friday.
It’s been a nice start so far for what forecasters call meteorological summer. Astronomical seasons, where summer officially starts on the summer solstice – June 21, are based on the position of Earth in relation to the sun. Meteorological seasons are based on the annual temperature cycle.
This from the NOAA website: Meteorologists and climatologists break the seasons down into groupings of three months based on the annual temperature cycle as well as the regular calendar. Meteorological spring includes March, April, and May; meteorological summer includes June, July, and August; meteorological fall includes September, October, and November; and meteorological winter includes December, January, and February.
We’ll continue to ease into meteorological summer with cloudy mornings and cool days for Saturday and Sunday. Expect highs in the high 60s to low 70s for the weekend and plenty of clouds for Saturday – more sun breaks on Sunday.
Forecasters are looking at a good chance for a new high pressure system to build into our area early next week and bring warmer temperatures into the 80s by Tuesday.
