OREGON AMS TEMPERATURE TREK IV

FEBRUARY 23, 2008, 6:30 A.M. TO 8:00 A.M.

This year’s temperature trek saw clear skies and calm winds across the metro area. Fog formed in some low normally colder rural areas, with a large area of fog from south of a line from the south edge of Hillsboro to the western edge of Beaverton.

Temperature patterns this year were in a typical pattern with the heat island centered over downtown Portland and the near east side. Coldest areas were in the Tualatin Valley and outer southeast over Happy Valley. We had no observers this year covering Clark County, Washington, normally the coldest part of the metro area.
