Hi MichealG, been thinking about you too, you Washington Stater, you.
At the house site valley floor we are at 672 feet. Goes up and up just a 1/4 mile east to 1500 by 2-3 miles, then to 2000, then to 3000; with a crow-fly’s 45 miles to the Cascades Crest if that crow would veer north or south of Mt Adams to keep itself under 4000.
But to get into this first Cascades foot hill valley you have to 1200-1400 feet road travel up and drop down in.
From Kent? Think about 10-15 miles east of you for the weather/frost equivalent. Can’t think of an appropriate town upper river valley name opposite you.
Ha! I am better with SW Washington and up out of the Willamette valley locations and names.
Go just 10 miles east of Longview up either the Cowlitz or the Coweeman rivers for the same as here. 5 miles east of Kalama, up the Kalama river for the same as here. 8 miles east of Washugal, up the Washugal river the same as here.
My-here: west-slope, inter-mountian altitude forced rainside is pretty much the same Roseburg/Cottage Grove Or, up thru southern British Columbia. Raintree Nursery’s growth zones catalog and a newer edition of Sunsets Western Gardeners book show the long north south bands well.
Latitude is not the predominate factor.
Rain shadowing from more western coastal mountains, the Olympics and Vancouver Island and the IS.
Being in one of the from east of Cascades ou- flow air spillover drainages like the Columbia river and Frazer river are very affecting. COLD dry winter outflow air at times. Compression overheating forced down slope air racing to the ocean late spring thru summer, early fall.
38F this morning and will zoom-zoom to 90+ today with a shift to from marine airflows to the east Inland Empire air up/over and down sloping to us by both the North and east forks of the Lewis rivers.
This is when the big “Yacolt Burn” of 1902, and re-burn 19teens, re-burn again in 1929 took place. Dry, hot under single digits humidity East Winds fanned.
Lowlands below 100 feet Portland Or and Vancouver Wa are greatly affected by off the ocean airs coming 90 miles up the broad Columbia river basin.
My Auburn, Seattle, Lake Washington surrounding relatives are all greatly Puget Sound air/water moderated.
Hey. You the pilot. Altitude matters. Barometric pressure matters. Humidity matters. And can all change in fractions of an hour increments, eh? Where you choose to live you are stuck with what fly’s in!
