Portland residents may enjoy some sunshine and pleasant weather today with mostly sunny skies and a high near 77 degrees. However, as the day progresses, those clear skies are expected to give way to clouds, leading to a chance of rain and thunderstorms after 2 am tonight, it looks like the calm before the storm with conditions favoring a quiet wind becoming south-southeast around 6 mph post-midnight and an 80% chance of precipitation; total rainfall may range from a tenth to a quarter of an inch, though this could increase in thunderstorm scenarios, according to the National Weather Service.
Wednesday's forecast, with showers and possible thunderstorms early in the morning followed by more rain, and then again, showers and possibly another thunderstorm after 11 am, with similar expected rainfall amounts and possible spikes during thunderstorms as we saw predicted for tonight. Light south winds will accompany the high near 67 degrees, providing little reprieve from the wetness.
The rain may take a brief intermission with only showers likely and a possible thunderstorm before clearing up by nightfall on Wednesday, bringing a low around 58 as the weather settles into a cloudy yet calmer rhythm. Even with a 70% chance of precipitation, new rainfall is expected to be less significant, under a tenth of an inch unless thunderstorms decide otherwise, making for a potentially gentler end to a tumultuous day.
Looking ahead, Thursday, with a 40 percent chance of showers amidst partly sunny conditions and a high near 69 degrees, but the rest of the week appears to follow suit—a mix of clouds and sun with similarly mild temperatures. Friday should bring mostly sunny weather with a high near 73, heading into a weekend that mixes partly sunny days and mostly cloudy nights, with temperatures remaining consistently in the low to mid-70s, as detailed by NWS.
