Best crack a beer. I’ve found those charts fairly accurate, perhaps even a tiny bit optimistic. They are based on 1/2 hr. low temps. Many times the low temps last longer than 1/2 hr. If it really gets down to 25F, any fruitlets formed will be gone.
Weather is terrible here too. We lost a lot of fruit buds from the winter cold, and will loose just about everything if the temps get as low as I see some predictions. Predicted lows to be anywhere from 18F to 21F.
Sam- I’m not sure how many people will understand what you just described, but I absolutely do. When a thick, large flock takes off it does sort of look like the whole ground is moving. And if you’ve not seen them until they take off, it will scare the #$%^ out of you! Around here we sometimes have flocks of almost 100 turkeys! Just 15 years ago you were lucky to see 2-3 wild Turkeys. TWRA says its their management, I’m not so sure but I will say their population growth has been amazing.
Mickster → I don’t know about plums, but I have had tart cherries form fruitlets then get hit by freezing temperatures. They looked a little brown the next day and a little shriveled, but they kept growing. As they matured, they looked less and less damaged and eventually produced normal tasting fruit with maybe some cosmetic damage. I don’t know if that is the norm or they just barely escaped the edge of what they could take. Also, tart cherries are pretty hardy, not sure what type of plums you have.
It’s a great day to plant fruit trees so I’m getting that done. It might be snowing but I’m still sweating! I’m going to get my new apple orchard finished today if I can. If I get a year off from harvesting fruit these trees are going to be looking wonderful.
You’ve probably said and I’ve missed it, but how many apple trees are you putting in your new orchard? What varieties?
These are my new two dozen apples Could use some help picking out 2 dozen apple trees from this list.
Clark,
Once of these day I may stop by your Upick Orchard. I will picking some sweet little yellow pears and Drippin Honey pears. You better speed up. With these apple trees. BTW, how far are you from Worlds of fun.
Tony
I’m on your way or I could meet you there one day. Let me know when your in the area next time. It takes me a little over an hour to get there.
Well. It was 85 here today. Float in the pool weather.
Just sayin’ 
Welcome to come out to San Diego if you’re tired of the March snow!
Well, if I was there, I’d probably tip you over for that comment. Btw, there’s no hiding your a red head. No one but, would have all those freckles 
Pretty nail polish too. 
Hah! Yup, all those freckles give my ginger-ness away, alas. And, that’s what about a gazillion inches of rain does to a S. California yard. I have some SERIOUS pruning ahead of me, there. And that’s sadly just one section of a large yard I have to hack away at. Ugh. All on me, too, as hubby has injured his back. Drat. Oh did I mention we’re smoking two whole chickens on the Traeger? Hashtag everybodyswelcome
Hubby has nice legs!
Heh, heh! Actually - he does. He’s a retired amateur bodybuilder. Just tryin’ to keep up with him (and, it was my leg day today in the gym, so thank you!) 
Did you really just do that? Did you really post photos of you relaxing IN THE POOL and cooking outside surrounded by lush greenery and 85 degree sunshine while I’ve been out in 37 degree weather trying to protect a single tree from the coming FREEZE and SNOW? You used to be one of my favorite people on this site. Used to be!
(kidding of course…I’d do the same if I could!)
I did, and I have to say, not ashamed because I lived in N. Indiana for 10 years, and shoveled my fair share of snow, broke the ice on the horse water buckets and troughs, slogged 300’ of hose from the garage to the barn because the (&^%3 barn water pipes froze (again, for the umpteenth time), and drove on skinny, scary, non-plowed county roads to the hospital, only to be told to go back out in my big A* truck (my 350 dually crew cab diesel Ford, the 2nd love of my life), to pick up stranded nurses and get them to the hospital. So, I deserve to make the rest of you all just a wee bit miserable, lol!!! Seriously, you’re all welcome to come out and visit anytime you’re done with that snow stuff. 
Hoosierquilt,
Lol I’m covered in mud and ice but I’ve got to admit I laughed very hard out loud when I saw that! Hard work deserves a float in the pool and your pears are just as hard to take care of as ours. Enjoy :0)
The forecast keeps fluctuating but at the moment, we’re supposed to get down to 25 Wednesday night. I have a few plums/pluots that already have fruitlets. Luckily I have a number of trees in pots so they’ll be coming in to the garage. Hopefully for everyone on the east coast, the temps are a little warmer than predicted.
The official Yahoo temp when I got up was 8 degrees here, with subzero windchill. I went for a 2-mile walk to try to get in shape for the garden season, and I about froze my face. I would take 37 degrees!
Brad,
Thanks for the well wish. Right now, WUisays, it is 15F but feel ilke 5 F.
The lowest tonight will be 5 F. If the wind does not die down, it would feel like -10F.
One apricot graft broke off. I dissected the buds. Actually, I did not have to. Dead as a door nail. I really think J. plums, pluots, nects and peaches are all gone since last week’s single digit temp for 3 nights.
I think stonefruit here in Atlanta are also at risk. My plums/pluots have already formed fruitlets and the peaches are full bloom or post bloom. My Contender Peach hasn’t bloomed yet though and would likely be fine outdoors. East coast growers who don’t have it might want to consider it given these spring temperature swings and the delayed bloom.
