JULY 2007
|
||
| 1st - 5th | Continuing unsettled with a little sunshine and showers. Thunderstorm late afternoon/evening 3rd. |
| 6th - 14th | Becoming rather brighter with very weak ridging from the Azores high although long sunny spells still few and far between. Some showers and thunderstorms in the SE but mostly missing this area. |
| 15th - 19th | Thunderstorm early morning of 15th but a warm and humid day follows. Sunshine and showers over the next few days, while extreme heat affects much of continental Europe. |
| 20th - 23rd | LP develops over northern France and swings across the Channel. Heavy bursts of rain from 01.00 to noon with thunder in mid-morning give way to a fine afternoon. This system leaves Kent relatively unscathed but causes flash flooding around London, the Thames and Severn Valleys with some parts of the country receiving over 100mm rainfall in less than 24 hrs. More heavy showers on the 21st and moderate rain for several hours early morning of 23rd. |
| 24th - 31st | Rather mediocre with predominantly cloudy skies and showers. More general overnight rain on 27th/28th and as a LP tracks across S England overnight 28th/29th. A fine end to the month however with long sunny periods on 30th and 31st. |

| ‡ SUN: Sunshine hours are calculated approximately and solely from solar radiation readings, but note that the solar sensor's exposure to sunshine is limited. The sensor receives only 75% of total possible sunshine exposure this month. There is no allowance for sunshine by visual observation only, so the figures above can be very significantly less than the actual daily sunshine duration. THW = Shaded Heat Index calculated with cooling/warming effect of wind and humidity to give an apparent temperature. THSW = Unshaded Heat Index calculated with cooling/warming effect of wind, humidity and full direct sunshine to give an apparent temperature. EVAPO-TRANSPIRATION is drying effect due to sun and wind, and is equivalent to "negative rainfall" |
