Severe Thunderstorms Expected Across Puget Sound This Weekend
WASHINGTON STATE — As the weekend approaches, residents of the Puget Sound should brace for severe thunderstorms forecasted to sweep across the region. With heavy rainfall, hail, strong winds, and frequent lightning anticipated, outdoor plans may need to be reconsidered.
Weather Conditions Ahead of the Storm
Before the arrival of the storms, Saturday is expected to experience warm but muggy conditions, with temperatures reaching the low 80s. The sticky humidity levels will create a palpable discomfort, so those planning to engage in outdoor activities like hiking or biking should conclude their outings by early evening.
Timing of the Thunderstorm Outbreak
The National Weather Service has increased focus on the Pacific Northwest, which is not often on their radar for severe weather as they generally concentrate on more active regions like Oklahoma and Kansas. Thunderstorm timing has grown more precise with updated forecasting models, predicting the onset of the storms as follows:
- 7-9 p.m.: Thunderstorms will begin to progress north along the I-5 corridor, reaching Lewis, Thurston, and Pierce Counties.
- 8-10 p.m.: Storm clouds are expected to enter King and Kitsap Counties, particularly over Seattle, unleashing numerous lightning strikes between Hood Canal and Snoqualmie Summit.
- 10 p.m. – Midnight: Weather conditions will continue to shift northward into Snohomish County and beyond, where bearsclosure with persisting rain, hail, thunder, and lightning will help to possibly recharge the unstable atmosphere.
Post-Storm Weather Outlook
After midnight, it is anticipated that lightning intensity will diminish, giving way to lighter, scattered showers by dawn as the storm subsides. Rainfall totals are predicted to reach approximately half an inch in areas stretching from Bremerton to Brinnon, which could help mitigate the current fire threats exacerbating the region and impacting incidents like the ongoing Jupiter wildfire.
Concerns Regarding Flash Flooding
Though the rain may pose certain advantages, it also raises alarms for flash flooding, particularly in any sparsely vegetated zones formed by recent wildfires. A Flash Flood Watch has been issued for both sides of the Cascades from Saturday night into Sunday morning, emphasizing the need for caution as heavy rains could default to severe habitats.
Looking Ahead to Weather Patterns
After a calmer Sunday with temperatures dropping into the 70s, a delightful Monday is on the horizon. However, residents can anticipate the return of summer rains by mid-week, adding much-needed variety to the generally dry August weather.
