The cool northwesterly breeze and variable sunshine on Sunday afternoon limited the rise in temperature to a maximum of 21.4C at 12.29 being 1.3C below average. The afternoon was marked by a rash of showers developing to the north of our area with the occasional one producing brief light rain and drizzle over our area at 13.00 and later at 13.35. The past night was again mild with a low of 12.2C at 06.57 due to the thick cloud cover. A longer shower of very light rain and drizzle arrived just before 07.30 that the precipitation in total for the twenty-four hours amounted to 3.6mm.
The start to Monday was overcast with the drizzly rain that stopped just after 08.00. Both major forecasters gave a 90% confidence forecast of four hours of significant rain after 02.00 early on Monday over our area, however, they were both wrong as the heavy rain once again was to the east. At least the minimal precipitation has refreshed the plant life but only dampened the surface, which will soon evaporate.
Today will be the last of the cool days with the breeze coming from the north. By Tuesday temperatures will begin to climb with some certainty that another heatwave will arrive later this week that could last much longer than the two heatwaves in June. The Jet Stream track by tomorrow will be to the north of the UK allowing a feed of hot air to arrive from the south that will build as the week progresses. This is due to the Azores High beginning to build a ridge of high pressure over the UK on Tuesday that could last into next week.
