Chief Meteorologist Justin Stapleton‘s Daily Forecast Discussion:
Winds are on the increase and steady rain will be moving through Oregon for the next few days adding another couple of inches of rain which, with the melting snow and ice, will create ponding on the roads and some potential for localized flooding. Overnight tonight, some scattered showers on and off with a chance for a minimal increase with a front moving through after midnight. Lows will hang in the mid 40s tonight.
One of the concerns we’re watching tonight is area streams and rivers that with yesterday’s heavy rain are getting close to flood stage. The only river gauge with immediate concerns is the Siuslaw near Mapleton on hwy 126. It crested around 4pm at 18.3′ which is slightly above flood stage of 18′. It’ll fall back tonight however, more heavy rain will likely put it along with the Marys River near Philomath under close watch through the weekend.

Thursday starts dry but another storm blasts in with more rain and wind Thursday night into Friday. Friday afternoon will also take a rain break but another storm will hit on Saturday. In all, an additional 2-4″ of rain is likely areawide. With the 8-14″ of snow that melted, that much more rain may cause smaller streams to get close to flood banks. It’s a trend we’ll be watching closely over the next few days.
The good news is no one will have to deal with ice or freezing temperatures as highs will sit in the low 50s and overnight lows in the mid 40s. In fact, mountian passes will also mainly see rain or a rain/snow slush with snow lines holding above 5000 feet most of the week. Conditions cool down next week and while the valleys and coast see more rain, the mountains will start to see some heavy snow showers through most of next week.
Have a great Wednesday night!
