Liam is part of Channel 4 News' history in being the first weather presenter the programme has ever had. He presents a forecast each weekday evening, as well as talking to presenters Jon Snow, Krishnan Guru-Murthy, Cathy Newman or Matt Frei to add insight and information on specific weather stories.
Liam also leads the Channel 4 Weather website where he writes blogs, news articles and engages with viewers through social media.
Prior to joining Channel 4 News, Liam gained nine years broadcasting experience on TV, Radio and Online, working as a Weatherman at the BBC Weather Centre in London – one of the busiest and most respected weather broadcasting units in the world.
Having started off as a weatherman on regional BBC TV and radio in June 2003, Liam became a familiar face broadcasting the weather in many of the BBC's Nations and Regions.
After a few years of broadcasting regionally, Liam went on to provide national and international weather broadcasts on the BBC's 24 hour news channel – BBC News, and also on the BBC's worldwide channel – BBC World News, which is broadcast in 200 countries around the world, having an estimated weekly audience of 76 million people.
Liam regularly presented the weather on BBC Breakfast, the Andrew Marr Show, and Country Tracks, all on BBC One.
In addition to this, he was one of the main weather broadcasters on BBC Radio 4 for the Today programme, as well as reading the Shipping Forecast.
With such an adaptable style of presentation, Liam also broadcast regularly on BBC Radio 5 Live and the Janice Long show on BBC Radio 2.
For around three years, he was also a regular weatherman on the Vernon Kay Show on BBC Radio 1, giving the weather forecast as well as plenty of humorous banter with Vernon!
Liam's professional, but relaxed and personable style of presentation has made him well received by viewers and listeners. A natural ability to communicate and engage with his audience brings him into their homes, and not just onto their TV screens.
With a range of experience in the broadcasting world, Liam is at ease giving weather broadcasts both in-studio and at outside locations, as well as giving news desk interviews when weather makes the headlines.
Liam contributed extensively to the weather aspect of the Iceland volcanic ash story in April 2010, as well as the record breaking cold weather that hit the UK in December 2010.
Liam has also written numerous articles for the BBC Weather website on weather stories making the headlines in both the UK and around the world, along with other topical issues relating to weather and climate.
