A major winter storm will organize across the Northern Plains today and then rapidly strengthen as it moves into the Great Lakes on Sunday. Heavy snow and blowing snow are likely to persist over the Great Lakes into Monday night. Dry and gusty winds will produce a critical fire risk across the central/southern Plains. An early heatwave will begin to intensify over the western U.S. into next week. Read More >

A Puget Sound Convergence Zone (PSCZ) forms when strong westerly winds flow around the Olympic Peninsula and converge over Puget Sound.
It generally forms north of Seattle, and may move southward to as far as Boeing Field or SeaTac Airport.
A PSCZ can cause a narrow band of convective precipitation along it, which can include rain showers, thunderstorms, or snowfall.
Strong south to southwest winds are to the south of the PSCZ and north to northwest winds to the north.
More model information for the winds around SeaTac can be found on the SeaTac Wind Page . |
