Piper to Seattle: Get those checks ready.
As Seattle soars to its 38th day at 80 or warmer and 19th at 85 or warmer amid blazing sunshine, the bill for the extended summer like weather is about to come due... with interest.
As in the price may be costing us a sunny Labor Day Weekend.
Of course it doesn't really work like that but longtime Seattleites would tell you they probably would have known even without an official forecast to broadcast the inevitable truth: Rain is coming on a three day weekend.
For now those, sun fans who have been basking in the warmest summer in ages have one more toasty day to soak up those rays. A warm evening will give way to a clear night with lows in the upper 50s.
The ridge of high pressure that has brought us our latest foray into the 80s is slowly moving out, but will still have enough influence to make for a sunny Wednesday. With the ridge a little farther away, it'll be a few degrees cooler, but highs should still reach the low-mid 80s.
Marine breezes rev up for Thursday which should bring a dose of morning clouds to the Puget Sound region then sunshine with highs dropping to the mid 70s.
Clouds will stick around much longer on Friday as the marine breezes reach full strength and sunbreaks may be limited. In fact, we could see even a few showers start to sneak in by late evening. Highs will drop to the low 70s.
Then, here comes the showers. A trough of low pressure will swing through on Saturday for a cloud day with frequent showers through the day. Some models as of now are painting around 0.33-0.50" of rain for Seattle by Sunday morning so that's a decent puddle-making rain and not just a few light showers. Highs will drop to the upper 60s to near 70, and could end our streak of days at 70+ at 36 days -- which would be 5th longest at Sea-Tac.
Scattered light showers remain on Sunday amid mostly to all cloudy skies -- it's not looking quite as rainy/wet as Saturday but still have to plan on getting wet at times. Highs will stay in the upper 60s/low 70s.
Long range models are undecided on Monday and early next week -- one model brings in a second round of showers while the other is leaning toward drying. We're going to lean with a few isloated showers -- that bill from the piper is quite daunting :)
