hmm

Well then go back to Seattle :)

Arizona summer

You got a couple of nasty comments. Not all Arizona residents are nasty. It is very hot and dry here. It's common to leave your air-conditioned home, get in your air-conditioned car, go to the air-conditioned mall or grocery store and back to the car then home. Very early mornings have been nice so far but I know it won't last. Summer lasts about 6 months in Arizona.

2018 Arizona Monsoon

According to the almanac the precipitation forecast for Arizona (Southern part of the state) for our annual monsoon season, is to be below average. Yet we are reading in the news that they say there is a good chance for above average rainfall for us. What's it going to be?? No one really knows, do they? Except God. I will keep my trust in Him for our weather.

Rain

Dear Lord please let the rainfall be above-average or at least normal

Rain

Wow nasty people above saying to just leave I am so sorry for those creepy people answering back like that I came here 30 years ago from Illinois and this dryness is terrible I Miss the Rains I wish the monsoons would be great this year.. we definitely need to pray on that.. I have been seeing beautiful pictures of other states that have so much Beauty including Washington.. I'm glad you're here you sound like a nice person totally understand you being overwhelmed by this heat and dryness.. I've been here 30 years and I'm overwhelmed! Take care

Northern Arizona - dry, dry, dry

We live in Prescott Valley where there were wildfire evacuations this past week - it's a mile high desert climate -- and was a welcome relief from Phoenix where we used to live. Two Summers ago we had record rains in August and now I don't even need one hand to count the number of times it's rained in the past year (and that's being generous because you need to include sprinkles!). Let's do a group rain dance for some good monsoons for all of the Southwest!!!

rain dance for Monsoon

We certainly need the rain and hopefully it will happen before long....but instead of a rain dance, lets try a group prayer. Maybe if enough of us ask for rain the ONE that can bring it to Arizona will see that it happens.

Rain

Yes wonderful idea!

Praying for rain

Yes. I keep praying for rain every day!

Rain Dance or Group Prayer/Meditations

I totally agree that everyone living in Phoenix should pray and/or meditate on rain to relieve us from the heat and help out our trees, flowers and plants. Fortunately, desert adapted and native AZ plants are usually fine as long as they get deep-soaking rain a couple times throughout the year. My flower garden and shrubs usually only need deep watering once a week but they do love it when it rains here. I have more appreciation for rain here than I did growing up in the Midwest. Rain here in the summer especially is very welcome! As long as it's not too much to cause excessive flooding. Every year whenever I hear it might rain, I meditate on gentle rain falling, just the right amount and so far this year and last year the rainfall at our house was nice. But rain falls at different amounts and different times all over the Valley.
