The 14 day weather forecast http://www.theweathernetwork.com/fourteenday/cabc0308?extcmp=sem_web_googleen_text&cities-en&gclid=CKH4l6qEzbYCFYF7QgodSUYAuQ shows the daily high crawling up slowly towards the end of the month, and no sign of frost.
However, as we can all feel, it's still pretty cold and the soil is even colder (and wet!) - go put your hands in some out there and you'll see what I mean. Seed sowed into that will just rot before germinating.
We'll need a good few warm and sunny days to heat the soil and dry it out some, but of course with the clearer weather comes clear nights and a high risk of overnight frost.
So I'll keep you posted, but I personally won't be planting any flax before the the last few days of the month based on this forecast.
