Please read the statements below - they are important.
Rain preceded by snow will move in on Monday. Any accumulations of snow should be small and temporary. After that the chance of snow seems minimal during the coming fortnight.
What snow is: An aggregation of ice crystals (flakes). Partially melted snow flakes mixed in with rain (sleet). Snow grains (little white golf-ball like things). Isolated crystals of whatever form (rare). I shall also include severe frost in this page - defined as air temperature below MS 05C (23F).
What snow is NOT!. Hail. Freezing rain or drizzle (which often gives clear (black) ice). Hoar frost. Rime. Frost. Icy patches. Soft Hail, or anything else.
Snow is also one of the hardest things to forecast in UK, so there will be errors in this page but I will try and keep them down to a minimum. Lying snow is snow that covers more than half the grass or soil - not tarmac.
I will, at times, refer to the ‘Snow Line’ - this is the 528DM total thickness line, it is a moderate guidance to how cold the upper air is over Rutland - to the north of the line you get snow to the south you get rain. In other words <528DM and the air is cold enough for precipitation to fall as snow.
Please note these forecasts are for interest and educational purposes only. They should not be used commercially or operationally. THIS IS NOT A WARNINGS PAGE
