In reply to tingle:
There's a section on weather in the Mountain training handbook Vol.1. should be enough information in there bring you up to SML level at reading the weather. There is probably a section in the winter one (vol 2?) but I don't have it so can't confirm.
Also I can recommend watching the biweekly MWIS forecasting video's especially if you are getting out. They are pretty informative and you can compare it with what you see. They started a blog last winter also.
Likewise for snow ice conditions the SAIS blogs and forecasts have a lot of information and they compare daily with the weather during the winter. Should be up to WML knowledge in the relevant handbook. Obviously this is Scotland based.
