June Weather Next 7 Days: 80 Degrees For Some!

April 19, 2018

11pm Thursday

Today was incredible wasn’t it?  It sure is true that stretches of gloomy/cool weather make us appreciate the sunshine.  I worked a half day today which meant about 5 hours in the sunshine.

I think I burned my face just a bit.  That is very possible from now through early September; the highest sun angle of the year is only 2 months away.  I think most people are surprised the sun is just as strong as late August.  In fact the sun angle is the same today as it was during the solar eclipse last year.

Just a quick note to let you know we are in a pretty stable “early summer” weather pattern for the next week.  The weak late April jet stream has shifted a bit to the north and seems to stay up there for the next week.  One weak system moves by to our north Friday night, but after that time the atmosphere warms up quite a bit.

The result is a switch of cool & wet to warm and dry.  A typical high temperature in June is the mid 70s and that’s where we are headed much of next work week.

Headlines Spring Summer

Could we hit 80 degrees?  Yes, I think that’s likely if current model runs hold.  As of now they are all showing a perfect setup for 80+ weather.

A) A classic “thermal trough” or low pressure west of the Cascades or along the Coast Monday-Wednesday.  That gives us easterly wind through the Gorge and over the Cascades.  A “downsloping” wind warms us nicely in this warm half of the year

B) Mostly sunny skies Monday-Wednesday

C) 850mb temps are forecast in the +12 to +15 range over Salem.  That’s the temperature in celsius around 5,000′ elevation.  It doesn’t get too much warmer than that in April; +18 is the highest from 1992-2009.

Past setups with these 3 ingredients in late April have pushed Portland metro high temps up to 80-85 degrees.  Get ready for summer weather for a few days.

A week from now you’ll need to water your potted plants, although there’s still plenty of ground moisture so you can skip watering the lawn/garden.

Enjoy the weekend!
