Weather review for a very wet July 2007
We would normally expect to see 52mm of rain in July, however on the 20th July 68mm were recorded, most of which fell within about 18 hours. During the whole month a whopping 141mm of rain was recorded. The total for the year to the 31st July stands at 508mm. In an average year we would expect to see 502mm of rain by the end of September. We have already had 71.7% of the average total rain for the year. By contrast in July 2006 just 26mm of rain during the entire month.
Temperatures in July were nothing special with a high of only 23.7'C recorded on the 16th July. Compare this with the 19th July 2006 when the temperature topped out at 33.1'C (Hottest day of the year). The low for the month was a chilly 7.6'C recorded on the 30th July. The average mean temperature for July is *16.6'C and due to the very damp weather the July mean was below average at 15.3'C. Since setting up the station this is the first month to record a monthly mean temperature below the average.
As we all know the weather in July has been dominated by heavy rain produced by active frontal systems that have been thrown at us by an area of low pressure that has sat across North Western Europe for the last 5 or 6 weeks. We could all do with a nice dry spell now and current long range forecasts indicate that is exactly what we are likely to get. The Azores high pressure starts to move north in the next few days and exert a more influence over our weather. So fingers crossed the early part of August looks drier and warmer by day. However it wont be all cream tea’s and bbq’s there will be showers at times in the afternoons and the early part of August could also see some very cool nights with minimum temperatures well down and not far from freezing.
