Expect more hot weather day... followed by increasing clouds and possible mountain thunderstorms later today.
One more day of hot, dry weather before cooler air and clouds return to the Pacific Northwest. Daytime highs will likely reach the upper 80s and low 90s here around the city. Air quality will be poor in Clackamas and Marion Counties where wildfire smoke from the fire near Estacada will fill the skies. Expect clouds to move up into the region from the south this afternoon. It may turn a bit muggy in the metro area. There is also a slight chance of afternoon thunderstorms in Cascades, Sourthern Oregon or Central Oregon.
Tonight, skies will turn mostly cloudy. Overnight lows will be in the upper 50s and low 60s. Tomorrow, the forecast looks much cooler. Skies will start out cloudy in many spots west of the Cascades before turning sunny in the afternoon. The morning cloud cover will help cool high temperatures down into the low 80s.
Looking ahead- the rest of the week looks cooler with a chance of light rain on Wednesday night and Thursday.
