Severe Thunderstorms and Heavy Rainfall Across the South; Heat Spreads Across the West and Southern Plains

A couple of frontal boundaries will move east and south from the Plains to the Gulf and Atlantic coastlines. These boundaries will focus showers and thunderstorms through the weekend, with scattered severe thunderstorms from the Southern Plains and across the Gulf Coast states. Locally heavy rainfall may also occur, which may be welcome news across drought areas. Meanwhile, heat spreads westward. 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 .
