Just driven from Stirling to Glasgow - that is not very nice driving conditions - the amount of surface water makes for some scary episodes.
With relation the the GFS and the snow "event" on Saturday, to be fair to it, it's had that modelled since Saturday/Sunday so is clearly sticking to it's guns. Still think Friday night going into Saturday, something a bit special is on the cards (not really basing that on anything scientific, more just a rumbling in the tummy and intuition...oh and not necessarily snow either)
Be safe outside if you're driving.
