The cloud formation I displayed build up in the afternoon in an otherwise clear sky, on a hot, humid summer day. They are more associated with the daily spotty tstorm activity in summer than frontal t-storm activity.
How often do you guys get the afternoon tstorm due to heat and humidity, and not associated with a cold front?
Joe90 might have been referring just to cumulus clouds as I was, rather than Cumulonimbus clouds.
Towering cumulus. The mountains rise to 6000 ft within a few kilometres of the coast, and most importantly face north. Also covered in dense, wet and dark coloured bush and with huge areas of rock and scree. The sea breeze is constant, and low clouds(2000 ft) will race inland at speeds of probably 30 mph plus. Another factor is wind from opposing direction -The east coast sea breezee will be meeting over the same area. This creates great uplift, with lots of moisture. 20,000 -30,000 ft foot cumulonimbus with very dynamic action is the result.
What is different from other places is that the uplift can seldom be sustained to the critical point. The sun disappears behind the clouds -the mountains are on the western horizon. The "engine" is turned off, and the clouds will collapse in a very short time generally covering about 80% of the sky within about 30 minutes. Thinking about it, 1 day in 4 might be more typical.
Cumulus buildup ( up to about 15000 ft)as you are referring to, above the mountains is the more typical pattern, and is almost the standard summer sky.
Here in our oceanic climate we get a few afternoon t-storms not associated with any cold front. Here is an example. Apparently the high that day was 80°F, dew point around 60°F, so not hot nor really humid.
Frontal storms however seem to be the strongest ones, from time to time there are some nice structures like this one.

The thing I enjoy about the summer frontal type is that the next day it is usually clear and beautiful here, with the high temps dropped down to the upper 70's (if really strong), but usually low 80's and much lower humidity. It brings an interesting change. Some summers this happens more than others. Depends on how many fronts make it down from Canada in the summer.
In the South, they get the pop up t-storms quite intense, with towering clouds building during the day, and then the next morning is sunny, very warm and humid with the process repeating. The fronts don't make it there in summer, usually.

Quite often actually. On UK weather forums thunderstorms are always associated with heat and humidity, indeed hot and humid spells in the UK will usually break down resulting in thunderstorms - June 2011 is a good example of this, after a hot and humid two days with temperatures up to 33C in south east England, thunderstorms broke out all over southern England.
Last year was particularly good for 'home grown' isolated storms that were very hit and miss, giving some locations up to 80mm of rain and 5 miles away nothing at all.

The slow moving ones can provide heavy rainfall amounts due to the intensity. When you wake up the next morning it is still muggy and hot with clear skies and it starts all over. It has to be hot and humid though. 91F (33C) seems well above normal for Leeds. How many days per summer on average do you guys get over 90F?
It didn't reach 33C here, no way, our record high is 34C, but it did reach 33C in Gravesend near London (highest UK temperature since 2006). Here, it reached 31C
Partly cloudy skies make for much more interesting photos. Grey skies make everything flat and obscure the mountains, and completely cloudless skies are all the same. I much prefer having a few clouds to provide some interest and depth.
