Mount Hood Area — 5-Day Weather Outlook
A tranquil mountain pattern prevails early in the period as a broad ridge of high pressure settles over the Cascades. Expect mostly clear skies and plenty of sunshine today and into tomorrow, with daytime highs climbing into the 30s to low 40s°F and overnight lows dipping into the 20s°F, fostering classic freeze-thaw conditions across the forested slopes and upper elevations. Winds will be light to moderate, with occasional ridge breezes above the treeline.
By mid-period, subtle changes in the upper flow introduce increasing cloudiness and the first slight chances of snow at higher elevations later in the day four. Although precipitation amounts remain modest, mountain observers may see scattered snow showers and flurries overnight as colder air begins to filter in aloft.
Into day five, the atmosphere remains marginally unsettled, with continued slight snow chances mainly above 5000–6000 ft, especially during the colder nighttime hours. Daytime heating may produce partly sunny skies with lingering clouds, while surface temperatures remain in the 30s°F, supporting wintry precipitation at upper elevations and dry, crisp conditions below.
Synopsis: A calm, sunny start transitions to a gradually more unsettled pattern with cloud increases and weak snow chances above the treeline. Temperatures stay generally cool, and winds aloft may strengthen slightly, but widespread impactful weather is not expected in this period.
