In this view as seen at Lowerfield some 3 km SE of Royston on 11th August 2004 at 0745 GMT the weather looks ideal for continuing to harvest the cereal crop, a gentle SW breeze drifting across the landscape in an unusually high temperature (for the time of day) of 19.7°C. However, appearances can be deceptive and the harvest has, in fact, stalled due to heavy rainfall the previous day, and further rainfall on most of the succeeding days resulted in this particular crop still standing as photographed over 2 weeks later. It remained mostly sunny on this day until mid-afternoon and the sunshine total for the day was 7.4 hours. The maximum temperature was 25.0°C.	A dazzling array of flowers and vegetables greets visitors to the Working Walled Kitchen Garden on the Wimpole Estate, some 10 km N of Royston. The Kitchen Garden is part of 60 acres of gardens including a formal garden with a parterre and informal pleasure grounds with daffodils and rare and unusual trees. The glasshouses seen on the right of the picture have been restored in recent years. The main pedestrian route to Home Farm, which is the largest rare breeds centre in East Anglia, now passes through the Garden so visitors can enjoy its many attributes on the way to view the animals. This view was photographed at 1247 GMT on 14th August 2004.	This menacing looking storm with visible lightning approached Royston slowly during the afternoon of 20th August 2004 from a NW direction, although radar images showed the main thrust of the line of storm cells was from SW to NE with only erratic movement of the line towards the SE. Consequently, when the storm had almost reached an overhead position it slid away to the NE and gave only minimal rainfall at Royston (Iceni) Weather Station on the E perimeter of the town. The storm as seen in this photograph was viewed from Poplar Drive, Royston at 1536 GMT. Other showers that day boosted the daily rainfall total day to 6.1 millimetres.
