WASHINGTON — A strong high-pressure system will dominate the weather in the region over the upcoming days, leading to significantly warmer temperatures on Sunday and Monday. Overnight, expect mostly clear skies with mild lows dipping only into the mid to upper 50s.
Heat Advisories are in effect for much of the Western Washington lowlands on Sunday and Monday, excluding the coast and northern islands, as temperatures are forecasted to reach the mid to upper 80s, with some areas potentially hitting low 90s. The warmest spots are likely to be in the Cascade valleys and southwest interior, where highs may approach the lower 90s.
On Monday, similar warm temperatures are expected, while coastal and island areas will see highs ranging from the 70s to lower 80s. This heat may pose risks for vulnerable individuals lacking air conditioning or adequate cooling measures. Additionally, pet owners should be wary of hot pavement temperatures that could harm their pets’ paws.
East of the Cascades, temperatures are predicted to soar into the 90s and low 100s over the weekend, with the heat continuing into Tuesday. Residents should exercise caution, as lake water temperatures remain chilly, ranging from the upper 50s to mid 60s, which can lead to cold water shock. It’s crucial to ensure everyone has life jackets, as falling into colder waters can lead to immediate challenges.
Fortunately, temperatures are expected to cool down starting Tuesday, continuing into Father’s Day weekend with highs mostly in the 60s and an increase in morning low cloudiness.
This forecast serves as a reminder of the importance of staying hydrated and prepared during heat waves, ensuring the safety of both people and pets alike.
