Hey Seattle, it looks like we're going to have a return to normal June weather!
For about an hour and a half...
The thunderstorms are gone and now we get a one day history lesson on what June days are supposed to be around here -- morning clouds with afternoon sun. Well, make that perhaps morning cloud and rest-of-day-sun.
A weak system is heading in well to our north into British Columbia -- far enough away not to bring any clouds or rain, but close enough to at least briefly turn the flow to the west -- yes, the west! That's the cooler direction! There are a few isolated showers out there this evening that will fizzle after sunset, but otherwise it'll be a clear evening and for most of the night. Then, low clouds will roll in from the coast toward dawn -- perhaps even reaching Seattle! Lows will be in the low-mid 50s.
Just don't expect the clouds to last long -- they'll burn off during the morning for another sunny day and that will be the last of clouds for a while. But the cooler flow will give us a slight bit of cooling Tuesday with highs in the upper 70s to low 80s.
For Wednesday, back to the swelter. The hot ridge of high pressure begins rebuilding and that will warm up the air mass again. Highs Wednesday will be in the mid-upper 80s with upper 80s and low 90s likely Thursday.
There continues to be signs that the 4th of July weekend won't be quite as hot as originally feared, but we might be splitting hairs a bit. By "as originally feared" we mean the long range models late last week and Saturday showed potential temps in the mid-upper 90s in Seattle. That, at least for now, appears to be off the board. For one, the east wind doesn't appear to be a factor again and the air mass isn't quite as hot -- squished a bit by weak systems heading far to the north again.
Bottom line? It'll be hot but, not HOT. (Well, maybe one capital letter's worth: "Hot")
Highs Friday through Sunday are now expected to be in the mid-upper 80s - maybe a few to hit 90 in the warm spots. Clouds? Shyeah, right. We'll keep an eye on this because if the models trend back toward their original thinking we'll have to bump those numbers up. But one thing seems for certain:
70s? Shyeah, right.
