Today weather presenter Tim Davies gave host Ally Langdon a welcomed surprise after her family popped up on the live weather cross in Wauhope, NSW.

Davies arranged the special guests as a surprise as he was on location in Langdon's home town.

Ally was overjoyed, but had a sneaking suspicion something was up.

"Mum didn't answer the phone yesterday," she exclaimed.

"Made me start thinking this morning that something was up. She can't tell a lie."

Davies insisted Ally's mother Helen was a late addition.

"I didn't know, Allison, until quarter past six this morning," Helen said.

Ally's mother, Helen, her father Heath and her brother David all showed up, much to Ally's delight.

She greeted her dad who couldn't resist making a jab at Karl Stefanovic.

"I can't believe how big Allison's shoulders are getting, but I guess it had to happen from carrying Karl this long," he said.

"Boom," Ally said as the team burst into laughter.
