The figure-hugging number clung to all of the right places and allowed the blonde beauty to highlight her enviable curves.
Featuring a pretty, origami-style neckline, she flashed her décolletage as she soaked up the early morning sun and advised viewers at home to take care in the heat.
The bright number featured three-quarter length sleeves and cinched in at the waist and left viewers at home distracted.
Taking to Twitter, fans of the 55-year-old gushed over her chic attire with one commenting: “Absolutely loving @carolkirkwood gorgeous blue dress today! So distracted I had to re-watch the weather. #IWantOne #BeautInBlue.”
Another added: “@carolkirkwood morning Carol! How pretty you look today! Have a wonderful weekend.”
“Morning Carol looking good in blue,” a third shared.
Someone else continued: “@carolkirkwood Looking totally stunning this morning Carol.”
Carol informed viewers at home that for many today’s forecast would be dry with some sunshine but there is the possibility of rain for some in Scotland.
There is a bright and sunny start to the day in East Anglia, the Midlands and northern England but there will be some cloud in Scotland with some showers later on.
