Kristi, who asked viewers to "please be nice about my clothing" when she publicly revealed her pregnancy, said that it all began with a single letter last week from a viewer unhappy about her maternity wardrobe.
She then read out the letter: "Nowhere on North American TV have we seen a weather reader as gross as you. Your front end looks like the Hindenburg and your rear end looks like a brick s**t-house. We now turn off Global."
Squire Barnes responded, "You know what? Good."
He added: "If you're going to diss us, please learn how to spell. Global is not G L O B E L."
But Kristi said she had also received other hurtful correspondence - including: "Buy some decent clothes and have some respect for your unborn child. You're not the first pregnant woman. OMG."
Another read: "Looser tops would look much more professional."
Kristi said: "We were expecting this. This happened last time I got pregnant. As I got bigger I started getting more and more bad notes and emails from people."
She then stood up to display her baby bump. "By the way, you can't really hide something like this."
To which Robin Stickley replied: "Why would you want to?"
But Kristi explained: "I feel like I'm a pretty confident person, I wouldn't be in this industry if I wasn't. I don't feel like this is affecting me, or has affected me.
"But I thought about some of the things I did last night; I checked the mirror to see how big I'm getting, I asked my husband, "Am I not seeing it? Am I getting really big?"
"It wasn't until I went to bed that I realised that - despite us saying that these guys are crazy - it's amazing that when you say something mean about someone it still affects them."
Kristi has been inundated with support on social media and her story has been shared 14,000 times on Facebook.
The news anchors finished their four-minute rant of support by screwing the letters up into tiny wads of paper and flicking them from the studio table to the floor, with the message: "Haters gonna hate. But if you're going to hate, learn how to spell."
