Sammamish-Issaquah Weather: Pleasant Weekend, Then A Wet Monday

SAMMAMISH, WA — Sammamish and Issaquah should be in for a pleasant weather weekend before November squeezes in one last storm, then December kicks off with a stretch of sunny days, according to the latest forecasts.

The National Weather Service expects a light morning drizzle Saturday before the clouds give way to some sunshine and calm conditions extending into Sunday. High temperatures for most should stay in the mid-to-high 40s.

Here is the 5-day weather outlook:

Sammamish:

Saturday: 50°/34° (Chance of rain, then partly sunny)
Sunday: 51°/37° (Mostly sunny/PM rain)
Monday: 48°/35° (Rain likely)
Tuesday: 47°/33° (AM fog, then sunny)
Wednesday: 49°/33° (Sunny)

Issaquah:

Saturday: 52°/36° (Chance of rain, then partly sunny)
Sunday: 53°/40° (Mostly sunny/PM rain)
Monday: 50°/37° (Rain likely)
Tuesday: 49°/35° (Mostly sunny)
Wednesday: 52°/35° (Sunny)

Late Sunday, a frontal system will move into the region, heralding in a short burst of wind and rain with a little bit of mountain snow into Monday afternoon. While precipitation and some breezy conditions are likely across Western Washington, forecasters do not expect significant impacts in the lowlands or the mountains. Snow levels will range from 2,500 to 3,500 feet, bringing 1 to 3 inches of accumulation and the potential for some travel impacts.

According to the early forecast, wind gusts will be strongest along the coast, the San Juans, Admiralty Inlet and western Whatcom and Skagit Counties, reaching as high as 30 to 40 mph. Breezy conditions elsewhere are likely, but wind speeds should be lower.

Forecasters said the front should move across Western Washington pretty quickly, passing as early as Monday night, and clearing the way for a sunny start to December that should last for the rest of next week. Daytime temperatures should stick to the high 40s to low 50s, while overnight lows could dip to just above the freezing mark.
