July's First Proper Rain

We hadn't had any decent rain at all in July until yesterday, Friday, when it rained on and off through most of the day.
Temperature & Rainfall Rate Records for 19 July 2019
The chart above shows the rainfall rate rather than the amount of rain that fell as that value of 73.0mm/hr (2.87in/hr) around 18:00 is the heaviest rainfall of the year. Put another way it would be the whole of July's expected rainfall in about 45 minutes. By the end of the day we'd managed 8.8mm (0.35in) and as of Saturday morning our monthly total is still only 15.6mm (0.61in) well below our July average of 56.6mm or 2.23in.
The forecast is for another mini heatwave next week so any water the plants can get at the moment will help them through next week with daytime temperatures forecast to reach 30°C or 86.0°F. The only disagreement the weather models have is how long the spell of hot weather will last with some suggesting a couple of days with a break down of the hot weather on Thursday next week and one suggesting it will last through into next weekend.
