Morning clouds will be followed by afternoon sunshine again on Wednesday as temperatures rebound into the low 80s.

Highs jump to almost 90 degrees on Thursday afternoon. There will be at least a moderate risk for heat-related illnesses. Stay hydrated, slather on the sunscreen and head into a building with air-conditioning if you don't have A/C at home. Unfortunately, sleeping could get uncomfortable by later this week for those without central air.

A heads-up: there's a small chance that wildfire haze could push into Western Washington on Thursday as winds shift from the north/northeast. Right now, we're uncertain how much smoke may arrive and what the impacts might be. It doesn't currently seem like it'll be a horribly smoky day, but keep in mind: smoke forecasting is challenging and changes day-by-day. Check the forecast at least once in the coming days for all the updates!

Beginning Thursday afternoon and lasting until Saturday, there could be daily rounds of isolated showers and thunderstorms over the Cascades. Stick with us as we monitor for developments.

Warmer weather gradually builds in Seattle this week.

A tiny about of wildfire haze is possible in Seattle Tuesday, but the hazy weather will mostly be in Eastern Washington.

As a westerly flow increases Friday through the weekend, we expect mostly good air quality around Western Washington. Any lingering haze should be pushed out of our backyard.

We're continuing to watch the weather in Central and Eastern Washington where several wildfires are ongoing. Today, firefighters will be facing breezy conditions in some areas — along with low relative humidity levels. There's a Red Flag Warning in effect for a tiny part of Southeastern Washington due to the threat of lightning.

Temperatures range in the 80s on Saturday. We'll return to the cooler, milder pattern of morning clouds and afternoon sunshine on Sunday and Monday. Temperatures mercifully drop to the 70s by the end of the seven-day forecast.
