Huddersfield looks set to get the first snow of the winter next week.
There is likely to be a covering on hills around the town, according to Huddersfield weather expert Paul Stevens.
But the forecaster said some predictions of a really heavy snowfall before Christmas are too early to confirm.
American weather experts have warned of bitterly cold winds from the east, bringing with it very heavy snow.
Mr Styevens said: “The American Global Forecasting System has undergone a revamp in recent weeks and is now regarded as being far more reliable than it was in the past.
“They were hinting at anything up to a foot of snow and sub zero temperatures for the Huddersfield area but it is still too early to be certain.
“What we can say is that the town will get a pre-Christmas cold spell and that could be as early as next week with some snow, certainly on the hills.
“The snow will be coming from the north west rather than from the east and will be followed by frosty weather and foggy mornings, but it will not be a severe or prolonged wintry spell.
“We need to keep an eye on what has been termed ‘The Beast from the East’ predicted by GFS as that could bring a bad winter as we had in 2010/11. Things can change very quickly”.
