METEOROLOGIST MARISA WOLOSZYN’S FORECAST DISCUSSION:
A slow transition Sunday as temperatures warmed above freezing. For those in the Willamette Valley temperatures warmed into the mid to upper 30s, but the fog kept the sunshine out and slowed the melting of the ice and snow. Other areas saw plenty of sun and temps into the 50s, which kick started the melting of the ice and snow.
The Willamette Valley will continue to experience thick fog Sunday night. A Dense Fog Advisory is in effect for the southern Willamette Valley until 9 a.m. Monday. Visibility is expected to be less than a quarter mile in some spots. Make sure to take it slow and have your lights on during Monday morning’s commute. Areas outside the valley will be mostly cloudy Sunday night with low temps in the mid 40s.
A cold front will move through late Monday afternoon. This storm won’t bring cold air but rain showers across the area (the snowline will remain above 5,000 feet). The ice and snow will continue to melt Monday as temperatures will be near 40 degrees in the Willamette Valley and Cascade Foothills, mid 50s along the coast, and upper 50s for the Umpqua Basin.
Two stronger storms will move in back-to-back Wednesday and Thursday. These storms will bring heavy rain, gusty winds and mountain snow. The snowline will be 5,000 feet or higher through the week; so ski resorts will get plenty of snow, while just rain will fall at the lower elevations.
Have a good week!
