The National Weather Service in Portland has issued an updated forecast for the area, delivering a mixed bag of sunshine, clouds, and anticipated rainfalls as we move through the week. The city experienced overcast skies this morning with a comforting blanket of 39°F, a dewpoint at 34°F, and calm winds, all contributing to the 80% humidity that's maintaining the chill in the air.

Portland residents can expect to mostly see the sun today, with the high temperature hovering near a pleasant 57 degrees. The winds, barely a whisper earlier, are set to pick up slightly, shifting south at around 5 mph. Stepping into the night, the clouds will begin to gather, setting the stage for a cooler evening with temperatures dropping back to around 39°F, as reported by the National Weather Service.

The daylight hours of Saturday will offer partly sunny skies and a slightly warmer high near 63, whereas the calm wind is expected to persistently become south 5 to 7 mph in the morning. But as we transition into Saturday night, those mostly cloudy skies come creeping back into the forecast, clutching a low around 42 degrees.

Come Sunday, the rain intends to make its presence known, with the weather turning wet mainly after 4 pm, and a high again near the 62-degree mark. The chance of precipitation will dramatically rise to 80%, as south-southwest winds start to modestly pick up between 3 to 8 mph. This pattern of rainy evenings is set to continue into the early week, maintaining the chance of rain largely steady, with Monday seeing a 40 percent probability. Temperatures during this period will slightly drop with highs near the mid-50s and lows bobbing around the high 30s to low 40s, according to the NWS forecast.

For those planning further ahead, the outlook remains wet with showers likely next Tuesday and continual rain through to Thursday. The snow level will also fluctuate, starting at 2000 feet on Tuesday before rising to 2600 feet in the afternoon but then taking a plunge after midnight Wednesday, lowering to 1900 feet. Keep your raincoats handy and prepare for a return to chillier conditions, as the snow level will drop further to 1800 feet by Thursday amidst ongoing showers.
