As Portlanders peek out their windows this morning, they're met with a blanket of overcast skies. But there's no reason to be glum, as the skies will clear up, giving way to sunnier days ahead. According to the National Weather Service in Portland, OR, we're expecting a 30 percent chance of showers and thunderstorms to pass before 1 pm today. Highs near 88 are expected under mostly cloudy skies before clearing for a sunny day.

Those planning evening events can expect mostly clear skies with a low near 64. Light and variable winds will accompany the calm conditions. By tomorrow, the forecast calls for sunny skies, with a high near 89 and calm winds.

The favorable conditions hold steady into Friday, with the NWS promising a repetition of sunny skies and a high nearing 89, and calm winds. However, it's looking like our plans could get brushed with a slight chance of showers after 11 pm, as a "20 percent chance" is on the weather's agenda.

Heading into the weekend, Portland keeps its sunny disposition mostly intact with a high around 83 on Saturday and just a few clouds to decorate the night's canopy at a low around 61. Sunday maintains the trend as the National Weather Service tells us it will be "mostly sunny," with a high near 82, and "mostly clear" as we head into the night, finding a low around 60, perfect for those staying out late to enjoy the evening.

And for those with an eye on Labor Day plans, the weather forecasts seem to be cooperating. The day is pegged to be sunny with a high near 84, followed by another mostly clear night as families and friends wrap up their gatherings, with the temperature dipping to a low around 61. Stretching our gaze to next Tuesday, get ready to pull out the shades and sunscreen because we're looking at a high near 90 under sunny skies.
