.DISCUSSION...Today will see similar weather as Saturday as broad
high pressure aloft remains over the region. Thermally induced
low pressure at the surface over SW Oregon will expand northward
across the Willamette Valley this afternoon, leading to a few
hours of breezy north-northeasterly flow. Winds will ease this
evening, then switch to southwesterly overnight as a southerly
wind reversal spreads north along the coast. This will likely lead
a greater marine influence Monday, and thus somewhat cooler
temperatures and higher relative humidity.
