An upper level low pressure area is west of Oregon, drifting eastward, pushing in some light rain ahead of the associated fronts. The moist warm front will push in some moderate rain around noontime today, giving us up to ¼” of rain through this evening.
The rain continues tonight as the associated cold front approaches then moves across the area tomorrow morning bringing an additional ¼” overnight tonight.
Once the front moves through around noon tomorrow we can expect some post frontal showers tomorrow afternoon that become more scattered overnight tomorrow.
We can expect about another ¼” of rain making the storm total somewhere between ½ to ¾” of rain between today and Thursday morning when the shower chance is minimal.
Friday on through the weekend the onshore flow is enhanced causing a thicker marine layer which results in less afternoon clearing then Monday we see a slight chance of a shower with a disturbance rotating into the area.
Afternoon high temperatures will be warming from the mid 60s now to the upper 60s tomorrow then up around 70 Thursday through the end of the week. Overnight lows remain in the mid to upper 50s.
