The heat is over, a bit more dramatically than we expected a few days ago, with temperatures today bringing relief for many, especially those of us without A/C who struggled to fall asleep in their sweltering bedrooms. Right now Sea-Tac is running a whopping 23 degrees cooler than this time yesterday. Thus far, Seattle has topped out at 70 degrees, and with the sun poking out between the high clouds, it feels much better than the scorching 96 degrees we topped out at yesterday. Around the Sound, temperatures are mostly in the upper 60s with some spots starting to break into the low 70s, and that is where we are expected to stay in the coming days. Out along the coast, temperatures are much cooler now that the winds have shifted to westerly with highs today sticking to the low to mid 60s.
As Shannon mentioned in the newscast, the two ways to break a heat wave are a marine push and thunderstorms and we are seeing both of those today. Winds have shifted to westerly all across the region, bringing much cooler air in off the Pacific. In the Cascades and into Eastern Washington, thunderstorms have been firing all day, with a few of these storms getting tagged with a severe warning, so if you’re going to be in the mountains or driving in the eastern part of the state, make sure you have that in the back of your mind. There is a very small chance of some thunderstorms around the South Sound, and we are starting to see a few sprinkles start to pop up on radar near the coast and in the South Sound. Most of the thunder activity, however, should stick to the mountains and Eastern Washington.
Tuesday brings with it the “stratus quo” that is so typical in June around Western Washington, and that’s what you can expect for the next few days. Mornings will start with mostly cloudy skies and temperatures in the mid 50s which will gradually give way to mostly sunny skies with high temperatures in the low to mid 70s. Up in the mountains, temperatures will be very comfortable for some hiking and camping with mostly sunny skies and highs in the upper 50s and low 60s. Out along the coast, morning fog should give way to partial clearing with cool temperatures in the low to mid 60s.
Thursday and Friday should bring with them slightly warmer temperatures and mostly sunny skies, a perfect way to close out the month of June! The start of July doesn’t look bad either, though there is some model disagreement about a chance of some sprinkles in the latter part of the weekend. Temperatures over the weekend, however, should still top out in the low to mid 70s, and rainfall, if any, shouldn’t amount to much.
Have a great last week of June!
