Portland, Oregon – As March approaches, residents in the Pacific Northwest are bracing for the possibility of snowy mornings in the lowlands of NW Oregon and SW Washington. Last year, a similar pattern brought snowfall in the first week of the month, with temperatures only reaching the mid-upper 40s during the day.
This year, the forecast indicates that the next 2-3 mornings could see snow levels dipping close to the valley floor west of the Cascades. Heavy showers moving through the area could bring quick accumulations of 1-2 inches or more, especially on Friday and Saturday mornings. Elevation may play a role in where the snow falls, but the unpredictability of the weather models means that residents should not solely rely on elevations for snow predictions.
People living near or above 1,000 feet are likely to see at least a dusting of snow each morning. For Thursday, steady rain is expected to turn into heavy, wet snow for communities east of I-5 and at higher elevations. However, temperatures are expected to rise into the 40s every afternoon, ensuring clear roads for commuters.
The unusual weather pattern is attributed to a chilly upper-level trough in the Pacific, which is expected to weaken and split by Sunday. In the past, a similar setup has resulted in morning snowfall in the lowlands against the Cascade foothills. The forecast suggests that an “anafront” could bring snow to the lowlands, with models showing increased snowfall predictions for Portland and surrounding areas.
Moving forward, the weather models indicate a mix of sun, hail, rain, snow, and thunder showers in the coming days. While the possibility of sticking snow remains, it ultimately depends on the intensity and duration of the showers passing through. Elevation continues to be a factor, but it is not the sole determinant in this weather pattern. Regardless, residents are advised not to worry about widespread freezing temperatures affecting their daily routines.
As the unpredictable weather persists, residents are encouraged to stay informed about changing conditions. The upcoming days may bring more surprises in the form of showers and potential snowfall, requiring vigilance on the part of the community. Stay prepared for varying weather conditions, as the cold air persists but without widespread freezing expected to occur.
In conclusion, while the region braces for potential snowfall, it is essential to stay alert to changing weather patterns and be prepared for sudden shifts in conditions. As the upper-level trough continues to influence the area, residents can expect a mix of precipitation and cooler temperatures in the days ahead. Be mindful of local forecasts and stay safe during this unpredictable weather period.
