Portland, Oregon, residents may see a return of snow this week, with fluctuating snow levels and potential for light accumulation in the metro area. A Winter Weather Advisory is in effect for the Coast Range and Cascades through early Friday morning, signaling a period of unsettled weather for the region. The possibility of low-elevation snow has prompted officials to urge caution, particularly during commutes.
The current forecast indicates a dynamic weather pattern, with snow levels initially dropping to around 500 feet tonight and tomorrow. This means areas at even relatively low elevations could experience snow showers. However, these levels are expected to rise to 1,200 feet by afternoon, potentially transitioning precipitation to rain in some areas. The fluctuating snow levels and scattered showers create an unpredictable scenario for the coming days.
Snowfall Predictions for the Region
The Coast Range is anticipated to receive the most significant snowfall, with up to 4 inches possible overnight at elevations above 1,000 feet. The Cascades are forecast to accumulate between 1 and 2 feet of snow by the end of Thursday. Within the Portland-Vancouver metropolitan area, light accumulation is possible, particularly in the central and southern portions of the valley late Wednesday night into Thursday, depending on the storm’s track. However, afternoon highs in the low 40s are expected to melt any snowfall that does accumulate.
KATU ABC 2 has declared a Storm Tracker Weather Alert for the potential of low elevation snow, noting that snow levels could fall as low as 500 feet at times. KATU’s forecast details scattered showers overnight and early Tuesday, with a mix of rain and snow possible.
Timing and Potential Impacts
Snow showers are expected to initiate Tuesday morning, with light accumulation possible above 500 feet. Drier conditions are anticipated by the afternoon. The National Weather Service reports that gusty winds and low elevation rain, along with heavy mountain snow, will impact the western U.S. Into Wednesday. The KGW forecast indicates that the Coast Range passes could see 6-12 inches of snow this week.
Although significant accumulation is not expected in the valley floor, elevations of 500 feet and above may see some sticking snow in the morning before temperatures rise. Heavier showers Tuesday afternoon could briefly bring mixed showers and some snow to low elevations. The possibility of light accumulation through the early morning hours on Thursday remains, contingent on the storm’s path.
The threat of brief and light snow showers returns to the greater Portland-Vancouver area, according to reports. KOIN.com details the potential for snow, emphasizing the fluctuating snow levels and the possibility of light accumulation.
What to Expect in the Coming Days
The weather pattern remains fluid, and residents are advised to stay informed about the latest forecasts. The Winter Weather Advisory remains in effect for the Coast Range and Cascades until early Friday morning. Road conditions may be impacted, particularly in higher elevations. The current forecast suggests a period of cooler, showery weather with lower snow levels, but any accumulation in the valley is expected to be minimal due to warming temperatures.
Looking ahead, the region will continue to experience showery conditions throughout the week, with highs in the low to mid-40s. Continued monitoring of the forecast is recommended as the situation evolves.
