Chief Meteorologist Justin Stapleton‘s Daily Forecast Discussion:
Temperatures are falling quickly into the low 20s across parts of Western Oregon tonight and are expected to dip again into the teens by early Thursday morning. Also, we’ll likely set another record similar to this morning’s record low of 18 in Eugene. Watch the roads overnight, as frost will turn overpasses and back roads icy.
All eyes now are waiting on an area of low pressure that is forecast to spin up near Vancouver Island, and head south down the coastline Thursday night before coming ashore Friday morning along the central coast. With the cold air in place, the storm will bring enough moisture to make Western Oregon (parts of anyway) a winter wonderland Friday morning! The timing is likely early dawn Friday through midday for the Southern Willamette Valley and central coast, mid-afternoon and evening for the Umpqua, south coast, and Rogue Valley.
There’s still some questions about the exact track the storm will take, we’ll know more over the next 24 hours. However, what I can promise is that anything that falls, will be in the form of snow because of the icy nature of the airmass locked into place right now. Preliminary estimates for snow are here, again these might adjust as we get new info in tonight:
With whatever snow does fall will ensure an extremely cold weekend set up. Saturday’s highs will likely not get above freezing and overnight lows may hit single digits in some areas! Sunday into early next week we slowly start to warm back into the upper 30s to low 40s staying dry.
Next chance for a storm comes Tuesday into Wednesday but as of now, it looks to be pretty mild compared to what we’re stuck in, so it will all be rain in the lower elevations, snow again in the mountains. Stay warm!
Have a great Thursday!
