The high pressure ridge to the west is building back towards its northeast, while the low pressure area associated with the weak front that went through continues to exit to the east. All this continues to give us a strong onshore flow that pushes in the marine clouds, especially at night, along with cooler daytime temperatures. So, tonight we see the marine clouds back in again with the winds northwesterly 5-10 gusting to 18 but easing some after around midnight, the low near 48.
The onshore flow eases tomorrow which allows for more clearing in the afternoon, winds northwesterly 8-12, highs around 62. The clouds will increase again tomorrow night, winds becoming northerly 5-10, lows near 48.
Friday the ridge axis builts northeastward over northern Oregon which helps to warm us up some, so with partly sunny skies and westerly winds 5-10, the high makes it to around 65, then with mostly cloudy to cloudy skies Friday night, the low is near 50.
Saturday the ridge again flattens as a trough of low pressure moves across and drags another weak cold front towards the area which increases the clouds and gives us a slight chance of mainly light rain, the high only near 60, then we see a chance of showers behind the front, after around midnight, the low down to near 46.
Sunday, we have an upper level trough of low pressure move into the region that increases the shower chance and cools things down a little more, the afternoon high Sunday only near 57, more showers likely Sunday night, lows near 45. Just to add a little variety to this, there is a chance that the Santiam Pass could see some snow falling above around 4500’ early Sunday morning. Somewhat rare for this time of year with summer only one week away.
It looks like we will see some more showers on Monday under mostly cloudy skies, the highs still down around 59, with a chance of showers still Monday night, the lows near 48.
We will likely see the showers becoming more scattered Tuesday but still on the cooler side, the high near 58.
