Portland woke Thursday, October 29, under cloudy skies with temperatures around 46 degrees, and the damp pattern is not quite ready to leave town. Rain chances remain part of the forecast, while fog is possible Thursday morning, before a mostly manageable Halloween weekend brings brighter breaks and lighter winds.

Showers and a Low Chance of Fog Thursday Morning

The National Weather Service in Portland forecast includes rain chances Thursday and a low probability of fog through Thursday morning. Temperatures should top out near 56 degrees, with mostly cloudy skies.

Rain chances rise again late Thursday night and into early Friday.

Halloween Looks Cool But Mostly Dry

Friday, October 30, brings partly sunny skies and a chance of rain, with a high near 56 degrees. The outlook is a little less soggy than Portland's earlier forecast, which emphasized broader shower chances and a possible thunderstorm risk, as Hoodline previously reported.

Saturday, October 31, looks fairly cooperative for Halloween plans, with little or no rain expected. Saturday night turns mostly cloudy with a low around 39 and another round of patchy fog after 1 a.m.; heavy rain and strong winds are not expected.

Warmer Weather Builds Next Week

Sunday, November 1, is expected to be partly sunny with a high in the upper 50s and little chance of rain. Monday is expected to be partly sunny, with temperatures generally rising through Tuesday; Tuesday, November 3, could reach 61 with partly sunny skies.

The midweek forecast becomes less clear. For Portlanders hoping to stretch Halloween weekend a little longer, the forecast offers a familiar Northwest compromise: foggy mornings, cool evenings and a few decent windows for getting outside.
