Weather is notoriously difficult to forecast as there is a number of factors that have to be taken into account. If one of those factors change, it has a knock on effect to everything. Snow forecasting is a major headache for even season and qualified forecasters. This last snow event 22/23rd March was difficult has we had 2 air masses fighting for supremacy. Warm, moist air, powered by a low pressure system off the Atlantic and a cold air mass coming from the East collided, mainly over the West and South West of the county , giving large accumulations of snow to these parts.
On the Thursday evening I voiced my concerns on Twitter regarding the warning level issued by the Met Office. I didn't think a Yellow warning was sufficient. Friday morning the Met Office raised their warning to Amber, AFTER it started snowing heavily in the upper Dales region and more noticeably, West of the Pennines.
The East and NE of the county escaped the heavy snow, and some of us got nothing more than a dusting. This is because the stronger cold air mass was at a slight angle, keeping the warm air confined to the West of the county.
Next week the cold theme continues, with more snow affecting mainly the eastern parts of the county, as it blows in off the North Sea. It will not be on the scale of what we are witnessing now. Snow is even possible for Easter weekend.
Thank you for taking time to read this, and if I get it wrong in the future (which I probably will) just bear in mind that I am an amateur, still learning the trade and bettering myself and my techniques. I provide this service out of my love and passion for the enigma that is weather , I have a family and a job, It's impossible for me to monitor the weather on a 24 hour basis and alert people to any changes that may affect my forecast. But I do try and update on Twitter and Facebook as much as I can.
