It looks like we have a few more days of this high pressure ridge and its associated weather before we see a pattern shift. This means if you like this week’s weather so far you are in luck, little change until Friday morning clouds and fog followed by afternoon sun. Luckily for the coast, you continue to have a weak onshore flow that keeps you up to 30 degrees cooler than us in the valley. Yesterday’s high temperatures include 70 in Tillamook, 68 in Astoria, and here in Lebanon we peaked at 99.7, which officially puts us at 100 degrees for the maximum. Yesterday’s records included Portland at 102 and Vancouver at 101, breaking their previous record of 100 set in 2020. Salem tied his record of 103 set in 1939 and Eugene tied his record of 102 set in 1998.
So the official forecast for the Tillamook area today, we are obviously starting our cloudy, hazy and misty skies but slowly clearing again today. Winds becoming westerly 4-8 and afternoon highs around 73. Clouds and patchy fog return this evening with winds calm lows near 57.
Tomorrow morning starts like today and the area becomes sunny again in the afternoon, winds still westerly 4-8, highs tomorrow a bit warmer near 75, then clouds and patchy fog return tomorrow evening, winds calm again, lows near 58.
Friday looks the warmest for the coast with Tillamook hitting near 77 under mostly sunny skies and little morning stratus, still afternoon westerlies 4-8. We get a hint of change that night with partly cloudy skies, winds still calm, lows near 57.
Most models show the ridge hanging into Saturday now, so we’re going with mostly sunny skies Saturday, highs near 76, partly cloudy again that night, lows near 57 again.
On Sunday, the ridge weakens and begins to slide eastward as a low pressure trough moves in and cooling begins. Sunday’s forecast is for partly sunny skies, highs near 72 then mostly sunny skies that night, lows near 57.
Monday and Tuesday look partly sunny and 69, mostly cloudy both nights, low near 54.
Heat advisories, watches and warnings have all been extended for the Valley region until 9 p.m. Saturday, as it appears the high temperature will also be maintained there until Saturday. There is a chance, however, that temperatures will not reach the low 90s until Saturday. We will look at the models to better understand this.
