Here is what I’m going with this evening (from our Facebook page this afternoon):
SNOW FORECAST FOR LOWEST ELEVATIONS
Steady rain changes to mainly heavy/wet snow after 8pm, could see brief sticking snow in the hills and east of I-205. Unlikely to affect traffic, except up around 1,000′ and far east side (Gresham, Estacada, Damascus, Camas, Battle Ground).
Snow showers off/on Wednesday……ZERO to TRACE accumulations.
SNOW FORECAST FOR HILLY AREAS UP NEAR 1,000′
This includes upper West Hills, Mt. Scott, hills around Gresham etc…
Rain changes to snow late this evening, could stick with a TRACE-1″ towards 10pm-Midnight. Then snow showers tomorrow with TRACE-1″ additional snowfall. No big traffic issues, but definitely so…me snow on roads for AM Commute up around 1,000′.
SNOW FORECAST FOR 1,000’+
This includes highest spot or two in West Hills, Sandy, Northern Clark County Hills etc…
Rain to Snow later this evening…1-3″ on ground by daybreak. Snow showers with another TRACE-1″ during the day tomorrow. Total 1-4″. Above 1,500′ up to 5″ is possible.
But here’s a big issue. Anything after midnight and through noon will be showery, so I could easily see one spot getting an inch near sea level, while 5 miles away the same elevation gets nothing! Another reason not to go with the 500′, 750′, 800′ wording that seems to be so popular nowadays…
