There is a chance of fog or low clouds near Portland Thursday morning, but skies should give way to mostly sunny conditions and a high near 66 degrees. Winds will stay light, making for a comfortable afternoon before a noticeably colder stretch settles in overnight.
Sunshine Thursday, Chilly Nights Ahead
The National Weather Service Portland forecast calls for mostly sunny conditions Thursday, with northwest winds increasing to around 7 mph and temperatures easing into the low 60s by late afternoon. Friday remains dry and mostly sunny, though cooler, with a high near 62 and a low around 40 Friday night.
Patchy fog could briefly form early Saturday, mainly before 9 a.m., before skies turn partly sunny and temperatures climb to about 63 degrees. The setup is a sharper cooldown than Portland's recent sunny run, with a cold Saturday morning in the forecast.
Frost in the Forecast
