Heating up in Seattle for the first day of summer

Seattle weather: Sunny and warm with temperatures in the 80s

SEATTLE - A ridge of high pressure moving over the Pacific Northwest will send temps soaring into the 80s for the first two days of summer.

It will be a toasty Thursday with high temperatures in the 80s for most of the central and south Puget Sound areas. Over the next two days, the coast will remain cooler and more comfortable with onshore flow.

We could see some cumulus cloud development over the Cascades today, but any chance of thunderstorm development will remain east of the Cascade crest today. Showers will be very isolated in that area, if we see anything at all.
