The Met Office have updated their warning of snow across much of northeast Scotland from Friday. The warning, which is still only of the yellow “be aware” variety, is now sixty hours long and lasts until Sunday lunchtime. Three of the four freely available NWP models are going for a significant blob of purple at the beginning of the warning on Friday (T+78) across northern Scotland. Curiously the French model has the precipitation of rain except on the highest mountains indicating how finely balanced things are between rain and snow to low ground. The impact level of the warning is at level three the highest, whilst the likelihood is at level one, and to be fair this event is still three days away and things can and I’m sure will change between now and then.
