Pressure and weather in Union Hill-Novelty Hill
Union Hill-Novelty Hill occupies the wooded upland between the Sammamish and Snoqualmie valleys east of Redmond, a few hundred feet above the Puget Sound lowland and already on the rising ground that leads into the Cascade foothills. Both facts change the weather relative to Seattle a short distance west. The elevation is enough that rain in the city is often wet snow here, and the winter snow level on any given Pacific system becomes the single most consequential local forecast detail, sometimes shifting three hundred feet in a couple of hours and deciding whether the roads are passable. The rising terrain also adds orographic lift, so precipitation totals run measurably higher than at the waterfront. On top of that, the Puget Sound Convergence Zone forms when flow splits around the Olympic Mountains and rejoins inland, and its band can settle over this area for hours while ten miles away stays dry. Summer is dry, stable and warm under the offshore high, with a nearly flat trace from week to week.
What this means for you
Elevation decides whether a system here brings rain or snow, and the pressure trace looks identical either way. Read a barometric pressure forecast for the system and the snow level forecast for the consequence.
