Agreed, as Crewe cold mentioned previously, since this is being shown on the GFS it is very intriguing. Of course watch the GFS flatten the high every single time with shouts for 'zonality' being heard. If it came off, the snow would have a longer lasting effect than in the epic late march spell that simply had a sun that was very strong.
I add the caution, that this is only one possible outcome, I suppose raging zonality is an equally plausible option although I ask, for how long?
