It will be music to their ears; the sound of the first heavy rain band of the year falling across Waikato farms this morning.  The latest rain radar showers a solid band of rain drifting in from Auckland and Northland and will cover all of Waikato by noon.  “The rain will be widespread this morning and although it could become a little patchy later today it is expected to regenerate this evening or evernight with heavy falls, some with thunder” says head weather analyst Philip Duncan.
