One more freezing cold night...
Temperatures will drop into the 20's again overnight, for most of us around Portland anyway, as clear skies stick around into early Monday.
That means another frosty start to the day on Monday, with patchy fog possible, but the air is pretty dry so we shouldn't see much, but cold enough it could be freezing in spots.
Morning sun will give way to mostly cloudy skies by lunchtime as a weak front approaches from the coast. There is a little moisture possible with this one, probably not enough to even notice, or make it to the ground, but if it mixes with any cold air that might be sticking around it could be snow flurries or freezing rain, maybe midday for the central Coast Range and later in the day in the Cascades and West end of the Columbia River Gorge.
Again, it's not a significant amount of precipitation no matter what shows up.
A better chance of rain moves in late Tuesday into Wednesday, and that will be warmer, raising the snow level in the Cascades above the mountain passes.
At least two more systems keep us under clouds with showers through the end of the week.
Overnight temps in the valley will generally climb above freezing as of Monday night. Daytime highs will settle into the upper 40s and possibly lower 50's through the coming weekend.
