Nothing but sun now and melting the snow away slowly.

Why is it that when it rains it can rain for hours upon hours, yet when it snows it hardly ever lasts more than an hour. :(

Snow over the UK is generally a result of warm fronts catching up with cold fronts. This is what has happened today - evidenced by the temperature profile over the last day:-

Cold before the front hits - slightly warmer at the front, followed by a mass of warmer air after. By definition this weather pattern is transient and is short lived.

Long spells of persistent rain are a result of slow moving areas of low pressure moving in from the Atlantic - they are typically warm (the warmer the air, the more moisture it can hold). You may get snow at the leading edge of the low but again, it's very short lived.

Persistent snow in the UK usually only occurs when we have a warm low captured to the north and forced south by a blocking high, which generates a "pembrokeshire dangler". Another scenario is when a west to east moving front hits a stationary cold front on the east coast - which has happened today but persistent snow looks unlikely now as the cold front is weakening, allowing the moisture laden front to continue out into the north sea - Norway will get all our snow tomorrow :-)

Heaviest snow in the east is usually from streamers off of the north sea in a easterly/north easterly. Getting stuck under a heavy streamer for a while in Feb 2009 and Dec 2010 gave me a few dumpings of over a foot!
