Hi Dominic ...if weather warnings were issued based on model output we'd be inundated! It looks like it'll be getting colder but the finer detail (which would result in a warning if snow was forecast) can only be determined much closer to the event .
Models will go be an indication of trend so I wouldn't get excited yet as I've learned from 6 or so years of lurking in this thread ...until theyre in the so called reliable (72 hrs or less) .
