With a mainly cloudy day Wednesday was cooler than of late with a maximum of 21.8C only reached late in the afternoon at 18.07 as brief sunshine arrived through breaks in the cloud.
It was dry day with the UV level still in the High category.
Overnight the cloud again acted as a duvet keeping in the warmth so that the thermometer did not fall below 17.8C until the arrival of the cold front. However, by 08.00 when readings were taken, the effect of the colder air, originating in the Arctic, was to drop the temperature down 2.3C with a current reading at that time of 15.5C.
The cold front arrived just before 6am Thursday with light drizzle that by 06.15 had turned into steady if brief rainfall that by 07.00 had cleared the area with precipitation amounting to just 0.6mm.
The cold front, as its name implies, saw this colder, denser air undermine the warm, moist less dense Atlantic air of recent days forcing it upwards and as it did so cooling and condensing the moisture into rain.
