Today was a very nice day, warm with a little afternoon breeze. A warm front will move into western Washington overnight and we will see high clouds as a result. This will keep it much warmer tonight - it also means a much quicker warm up tomorrow. The high clouds will also increase the humidity, making it a bit on the muggy side.
The high starts to break down tomorrow night and that will let in high clouds on Sunday. These clouds will cool us about 10 degrees but Dads need not worry: it will still be a nice day, just not as hot. A weak front moves through the northern part of the state Monday and cools the area least another 10 degrees with a few showers.
Saturday: Mostly fair and muggy, 70 / 75 coast, 83 / 88 inland.
Sunday: Mostly cloudy, 60 / 65 coast, 74 / 78 inland.
Monday: Mostly cloudy with a few showers north, 55 / 58 coast, 62 / 66 inland.
