Well, we have had some nice flurries including a few heavier showers this afternoon here in Poole. So I'm now happy as a pig in poo.

Good forecast but 

It is 36 hours to kick off - anything could happen. A slight westward correction would see many of us receiving 'the scraps'.

Yes, still times for upgrades /downgrades.

The fact it is realistically our last chance of the winter for meaningful snow makes it even more nerve racking!

Temperature has dropped like a stone here after a snow storm left 2cms of snow cover in 20 mins earlier!

Already down to 6.9 deg c

I think I'd cry and would run around Parkstone doing a Fabrizio Ravanelli style goal celebration.

I think it is called snow sublimation where moisture from the snow is extracted straight into the air without turning to water first. I stand to be corrected if I haven't explained this very well!

Very interesting, you learn something new everyday. I also keep hearing how due to the air being so dry that means no ice forming on car windscreens to scrape off etc, well funny that as scraping the ice off the windscreen is exactly what I had to do this morning before driving off lol

Speak for yourself, I’ve never seen 15cm of snow this side of the millennium I don’t think! If I can have 15cm I’ll be happy for you to have 35cm, Deal?

I hate to be pedantic @Smartie but it doesn't get frosty but a wet windscreen can turn to ice - I know, I know it sounds daft!

Yes but if you had -5c with a polar maritime airmass (a lot more moisture) you'd have been scraping for a lot longer.

Dew points infer the temperature at which moisture condensates out of the air. 

As soon as the air temp drops below the dew point frost will form. 

You can have temps of 0/-1C with dew point of +2 and you'll get a lovely 'hoar frost' 

whereas like at the moment with temps down to -5/-6C  and dew points around the same temp or colder a thick frost doesn't form. 

Obviously on metal and glass these rules alter slightly and very localised variants will effect things but as a rule when dew points are lower than air temps frost doesn't really form :)
