Is the forecast going to plan?

Today was always going to be a fine balance between rain and potentially very heavy snowfall in some areas.
I mentioned earlier that the intensity of the precipitation could be crucial. We are now seeing the intensity pick up in north Wales and the north-west Midlands. This is turning more of what was falling as rain to snow.
As that higher intensity area moves north, snowfall will become heavier on the hills of north Wales, the Peak District and Pennines over the coming hours, before turning back to rain. It could also mean some lower lying areas will see a bit more snow, mixed in with the rain, at times.
Even ahead of that, we are now seeing the forecast snow start to arrive more widely on the north Pennines and Northern Ireland.
The Met Office yellow warning for snow in southern Scotland now has an earlier start time of midday, indicating that things are progressing a little quicker than expected earlier.
