Thats right Brian. February historically produces more Scandy & Siberian highs than other winter month, however any lying snow melts quicker than a chocolate fire guard with the sun hitting up and the afternoons get longer again.
February, despite its 28 days compared to January's 31, produces more days of snowcover in some areas of the British isles, on the LTA.
So, when we look at these facts, we see that upper air temperature, actual snow falling and then laying, assisted by colder air-masses, tends to outweigh the sun strength argument, which, frankly, is a non starter for me.
