It was a hot week last week, and then there were the thunderstorms over the weekend. Just to add to any other unusual occurrences, we had a full moon yesterday. So, a ridge of high pressure was responsible for the added heat during the week, which was followed by a disturbance that rode up across the area, giving many an impressive show of lightning with lots of thunder. Now the ridge has drifted east past Idaho as a trough of low pressure approaches the coast, increasing the onshore flow which in turn, will help bring this week’s temperature more in line for the time of year.
So, for Tillamook, this pattern brings the typical weather for the coast of morning fog and clouds, followed by some clearing in the afternoon along with increasing afternoon onshore winds. This pattern yields high temperatures today in the mid 60s, along with gusty afternoon northwesterly winds, gusting to 20-25. The marine layer pushes in some again tonight and the winds decrease, and the overnight low temperatures drops to around 47.
Any marine clouds burn off by midmorning tomorrow, so we see sunny skies with the winds again increasing tomorrow afternoon, becoming northwesterly 10-15 gusting to 20, and the afternoon high temperature reaches 68. Look for mostly clear skies tomorrow night, the clouds do push in to some degree, the winds slowly diminish, the overnight low drops to near 49.
It appears a low pressure area moves into British Columbia midweek and maintains the onshore flow over our area so back comes a mostly sunny day Wednesday, with northwesterly afternoon winds 5-10 gusting to 15, afternoon highs again near 68. A partly cloudy night is expected with diminishing winds, the marine layer pushing in some fog and stratus in the early morning hours, overnight lows near 50.
The pattern appears to change little into the weekend, giving us a forecast of mostly sunny to sunny afternoons with highs in the mid to upper 60s, the marine clouds push in during the early morning hours with overnight lows down around 50.
The models show the low to the north moving east across Canada over the weekend, the onshore flow weakens, and this would allow the afternoon high temperatures to begin to rise by Sunday here, climbing to near 70, and into the upper 80s over in the valley. Overnight lows are expected in the low 50s.
