Cooling down some over the weekend..


Looking at some of the models here, it appears that today will be our last REALLY WARM TO HOT day here in the inland Puget sound region as high temp this afternoon once again look to be in the upper 90`s to maybe low 100`s. Tomorrow should be a bit cooler and not so hot with highs off the 12zWRF this morning showing mid-upper 80`s and then about the same for Fri with maybe a few low 90`s in the south sound region. Sun also looks roughly the same with with mid to upper 80`s. So some relief is in site for the weekend, but it`ll be a gradual cool down. Also, our ridge looks to weaken some over the weekend and into next week as an upper level low rides up the west coast coast and eventually being off the OR/WA coast by what looks to be the Wed/Thurs time frame. GFS/Canadian/EURO/GEM model show this upper level low for us as well and also about the same time frame....mid-late week. And if this holds true, then we possibly could have some convective showers over the mountains and maybe the lowlands to as this upper low looks to be having us in SE-ESELY winds aloft. So will have to see how this pans out. Also to note is that 500mb heights are in the 570`s/ 580`s during this time so should be in high 70`s to 80`s, but that is going out on a limb, but dose look to be that way for now.

Have attached a couple photos I took of the cumulonimbus clouds I saw yesterday on my way home that built up over the Cascades during the afternoon hours.
