Why does not every rain storm have lightning and thunder?
Lightning only occurs in high energy storms. This means they have a lot of CAPE (convective available potential energy, often weathermen will say instability). It can rain with low CAPE, but it doesn't necessarily come with lightning.
The Short Answer
Lightning only occurs in high energy storms. This means they have a lot of CAPE (convective available potential energy, often weathermen will say instability). It can rain with low CAPE, but it doesn't necessarily come with lightning. High CAPE results in storms with considerably more energy. Areas like the West Coast of the US or the UK are examples of areas that consistently have enough precipitable moisture, but hardly ever experience substantial CAPE values. Areas where it is raining out West right now have CAPE values around 250 J/KG. Tomorrow the parts of the southern plains that will experience severe weather will have CAPE values of 3000 to 4500 J/KG, or more than 10 times as much energy to work with.
