GFS 1000 hPa Geopotential Thickness (dam) Forecast Charts for the UK and Europe...
1000hPa temperatures is approximately 10m above sea level. Thickness values give an indication of how warm or cold the air is. Lower thickness values indicate colder air sectors (<=-12'c - 510dam, <=0'c - 528dam). Higher values indicate warmer air sectors (=>12'c - 546dam, =>25'c 564dam). Thickness values are one of the parameters sometimes used to help determine whether precipitation will fall as snow or rain. If the air is of a continental source, snow can fall with thickness values of about 530dam or lower. If the air is from a maritime source values of 522dam or lower may be required for snow.
