Tomorrow sees the end of the easterly flow and pool of polluted, dusty air that has been over the UK for a few days now, with a return to more common conditions with the Atlantic feeding in bands of rain at times with westerly/southwesterly winds. And a small matter of Michael's forecast and tips for the winner in both the Grand National and Boat Race (the tip is just for fun of course, don't blame Michael if the horse loses and a boat sinks!)
