The days are getting longer and the sun is growing stronger, but temperatures still refuse to climb. Cold air has been sitting over the UK for a long time now and we need to look to milder weather from the Atlantic to shift it. That looks unlikely while a large area of high pressure continues to dominate the scene right through to the middle of the month, but there are signs that it may start to ease away later in March, allowing some of that milder Atlantic air to edge in from the west.
