From Snowy To Soggy

Chief Meteorologist Justin Stapleton‘s Daily Forecast Discussion:  

The snow and ice are (mostly) melted so now we shift our attention from snow to soggy as a series of sub-tropical storms moving into the Northwest this week. Temperatures will stay mild so with the additional rainfall, some localized flooding may be an issue for catch basins and small streams.

Tonight, the big melt continues as lows will stay above freezing in the mid 30s. The concern tonight is the melting snow cools the air near the ground, getting it down to the dewpoint, which creates a dense fog. Visibilities are less than a mile in the valley and with some tree limbs still on the ground, travel will be tricky tonight.

Tomorrow we’ll see the first of a couple of juicy storms bringing some heavy rain tomorrow night and into Wednesday. A High Wind Watch has been issued for much of the coastline, with winds increasing to 25-35mph, gusting to 50-65mph mainly in the PM, through the night. Heavy rain is likely by tomorrow evening, steady turning to showers by Wednesday. Both days will stay mild with highs in the upper 40s and low 50s. In fact, most of this week with the sub-tropical nature of the airmass, will stay well into the 40s and 50s, overnight lows in the 40s.

More storms are arriving on Thursday night, Friday and into Saturday. In all, parts of the region may be seeing between 2-4″ of rain. That along with the melted snow and ice could push stream banks and local low spots to some minor flooding. We’ll watch for any forecast trends on area rivers that may be getting close to flood bank height. Otherwise, it’s back to some much needed rainfall over the next 7 days in the Northwest.

Have a great Monday night!

    I wish that the weather forecasters would not be so “flip” with the word FLOOD. Do they not realize that many people in Lane County, have been devastated by flood waters? We hear that word, and immediately our hearts race, anxiety levels go sky high, and blood pressures rise. If you need to advise the public of the chances of flooding… PLEASE tell us WHERE????? is it at the coast? In Portland, in the valley? or just WHERE? so we can either be on alert, or on the other hand, we could relax a little. I went through the ’96 flood, and my home was under water..(and having NO flood insurance to boot.) So, each time I hear that word, I panic. It’s not fun to live in FEAR for a week or so, with that kind of threat, looming over my head.. Please tell us where you expect the waters to possibly flood.. not just a “general” expect local flooding, statement. I know my neighbors feel the same way.
