Just a quick health warning for that chart, it shows cumulative snow precipitation not lying snow. You could have 30cm of wet snow falling with 0mm of it lying.
If temps were low enough it would be a good guide, but because we're marginal it's not.0 -

If you're following the Apergè model it doesn't give very much rain/snow across the country but if you're following the Hirlam it gives widespread snow across most of the country.
Just to give an idea of what's going on and the difficulties in the forecast. This is a clip from the Met Office.
On the clip on the monitor behind him it appears to show the low pressure coming down across the country at 6o'clock tomorrow and the precipitation with it. But as Alex says they're looking at two different charts.
I know how you feel mate.

It really is a nowcast. Impossibly to predict showers merging and rain/snow in marginal areas.0 -
And that's the difference between the met office and met eireann, black and white. Met eireann would never do videos like that to keep people informed especially people who cannot read weather charts and rely on updatespedigree 6 wrote: »If you're following the Apergè model it doesn't give very much rain/snow across the country but if you're following the Hirlam it gives widespread snow across most of the country.

I remember the eagle( John Eagleton) saying something similar back in December 2009, we missed out on over 12 hours of heavy frontal snow due to the temperature being 1 - 2 degrees too high. As was said nine out of ten times it goes wrong for us, but i suppose that makes the one time it goes our way extra special0 -
