what will happen if you transplant tomatoes and then it turns out to be cloudy & rainy for a week?
Its better if its cloudy, to certain extent if rainy unless plants get flooded or washed out. I prefer cloudy/rainy over 90 degrees high heat. this will give time to establish in cooler climate and will not wilt or go into transplant shock
That's when I prefer to plant. It gives the new transplants a chance to acclimate without getting the additional stress of blistering heat and sun. Especially if the roots were disturbed during the process.

I had a large tree rose to put in the dirt and I decided the recent overcast spell we have had in SoCal was my last best hope this summer! Happy to report the patient is doing just fine! Linda
