Give the clouds ideas.
Water your lawn and plants and trees.
Water the sides of your houses especially if brick. The South and West sides.
Spray your roof with water
Keep windows covered on the south and west sides. Tin foil or some reflective board. Keep blinds closed when the suns shining. Close inside doors to that side of house if possible and use an exhaust fan to pull air out.
Use your kitchen exhaust fan to remove hot air.
Freeze ice in plastic bags.
If screens are torn, mend them. At least with duct tape if you can’t replace screen at this late date.
Water gardens etc morning and evening
Set a block of ice in front of a fan in a bowl to cool air in your immediate vicinity and in bedroom at night. Take the ice out of the bag to add cool moisture.
Go to a cooling off place in Snohomish County or your county.
Go to the snow line.
Camp in the shade of your yard if you have a large tent.
Employ ice and fans.
Do whatever your common sense suggests to stay cool. Take a shower.
Have fun and thank goodness for the rain whether you see it or not! That is a rain dance!
