Of course, it wasn't sunny when that snow was falling. 
Get rid of the sun, via a nice overcast, and you can get your -2 or -3C daytime highs at the end of February. As soon as the sun comes out, though, drip.. drip.. drip..
The only way to avoid it is to get some really dry, deep cold air involved, i.e. dewpoints towards the minus double digits. That delays things somewhat, but is vanishingly rare down here.
Bear in mind as well that the spell at the end of Feb saw record-breakingly low thicknesses for the time of year!
