Portland is gearing up for a potentially messy and cold stretch of weather as temperatures drop and a mix of rain and snow threatens to create slick conditions on the city’s roads. With snow levels forecast to drop as low as 500 feet, higher-elevation areas may see accumulations, while the city itself deals with frosty mornings and slippery commutes.
The National Weather Service has issued a Cold Weather Advisory, warning residents of freezing overnight temperatures and the possibility of icy patches, especially during early morning hours. If you have travel plans this week, it’s time to plan ahead.
CALM FOR NOW, BUT CHANGES ARE COMING
As of Sunday, February 9, Portland is experiencing a relatively calm day with mostly clear skies and temperatures hovering around 34°F (1°C). The high today has reached 43°F (6°C), but don’t let this mild start fool you—freezing conditions are just around the corner.
HERE’S WHAT TO EXPECT THIS WEEK: DAILY WEATHER BREAKDOWN
Monday, February 10:
- High: 44°F (7°C)
- Low: 27°F (-3°C)
- The day will be mostly cloudy, and temperatures will remain chilly. Patchy fog may develop before 9 AM, so morning commuters should be cautious. As temperatures drop overnight, frost and icy patches are likely.
Tuesday, February 11:
- High: 41°F (5°C)
- Low: 26°F (-3°C)
- A sunny but cold day, with gusty winds adding to the chill. East-northeast winds may reach up to 21 mph. Make sure to bundle up, as wind chills could make it feel much colder.
Wednesday, February 12:
- High: 43°F (6°C)
- Low: 29°F (-2°C)
- Another sunny but cold day, with temperatures staying below normal. Frosty conditions are expected in the early morning, so allow extra time to scrape your car and drive cautiously.
Thursday, February 13:
- High: 37°F (3°C)
- Low: 31°F (0°C)
- The weather takes a turn as a system moves in, bringing clouds and the possibility of snow flurries. Light snow accumulations are possible, especially in higher elevations. Even a small amount of snow can cause slippery roads, so stay alert.
Friday, February 14:
- High: 45°F (7°C)
- Low: 35°F (2°C)
- Partly sunny skies return, and temperatures will be slightly milder. Any leftover snow or ice will likely begin to melt, but caution is still advised on shaded roads where ice may linger.
Saturday, February 15:
- High: 43°F (6°C)
- Low: 42°F (6°C)
- Cloudy and cool, with a chance of light rain. Precipitation will likely be in the form of rain due to slightly warmer temperatures, but some areas at higher elevations could see a rain-snow mix.
WHAT’S CAUSING THIS WINTER WEATHER?
The cold conditions are the result of a high-pressure system to the north pushing Arctic air into the region. This cold air will combine with a moisture-laden system moving in from the Pacific, creating the potential for a mix of rain and snow. The city itself may not see significant accumulations, but areas above 500 to 1,000 feet—like the West Hills and Mount Tabor—are more likely to get snow.
Additionally, overnight freezing temperatures will increase the risk of black ice and frost, especially on bridges, overpasses, and untreated roads.
WHAT YOU NEED TO WATCH OUT FOR
1. Slick and Icy Roads:
With overnight lows dipping into the 20s, any moisture on the ground could freeze, creating dangerous driving conditions. Black ice is especially deceptive and can form even when roads appear clear.
2. Frosty Windshields and Sidewalks:
Morning commuters will likely face frost on their windshields and slippery sidewalks. Allow extra time to scrape ice off your vehicle and wear shoes with good traction.
3. Snow in Higher Elevations:
Residents living above 500 feet should be prepared for possible snow accumulations. Even a light dusting can cause significant travel disruptions in hilly areas.
4. Wind Chill:
The combination of cold air and gusty winds could make temperatures feel much colder than they actually are, especially on Tuesday. Be sure to dress in layers and cover exposed skin.
HOW TO PREPARE FOR THE WEEK AHEAD
1. Monitor Weather Updates:
Stay informed by checking local weather reports or using reliable weather apps. Conditions can change quickly, and knowing when snow or ice is expected will help you plan ahead.
2. Prepare Your Vehicle:
Ensure your car is winter-ready with proper tires, an ice scraper, and an emergency kit. Keep your gas tank at least half full to prevent fuel line freezing.
3. Dress in Layers:
With wind chills making it feel colder than the actual temperature, wearing multiple layers will help you stay warm. Waterproof outerwear is also recommended, especially later in the week when rain is expected.
4. Drive Safely:
If you must drive during icy or snowy conditions, reduce your speed and increase your following distance. Be particularly cautious on bridges and overpasses, which freeze faster than regular roads.
5. Watch for Vulnerable Areas:
Shaded spots, hills, and untreated surfaces are more likely to be icy. Take extra care when walking or driving in these areas.
LOOKING AHEAD: WHEN WILL CONDITIONS IMPROVE?
Portland’s weather will remain cold and below average through midweek, with some relief arriving on Friday when temperatures are expected to climb slightly. However, the potential for rain or a rain-snow mix this weekend means residents should stay vigilant. The best advice is to be flexible with travel plans and continue monitoring local forecasts.
FINAL THOUGHTS: TAKE THIS COLD SNAP SERIOUSLY
While this week’s winter weather may not be severe by Midwest standards, it’s enough to cause disruptions in Portland, especially given the city’s limited snow-handling infrastructure. By staying prepared and taking simple precautions, you can avoid the worst of the potential headaches.
