Thunderstorm in the making!

Today the clouds have built up quite well! There have been spits of big rain drops this afternoon, and there has been some rumbling to the south, where there is a nice developing cell. Thunderstorms have been predicted for today which will probably occur this evening. The winds are becoming erratic which is a good sign for possible lightning activity. Some cells are also beginning to join up with other cells. Temperature this morning at 08H00 was 20 degrees celcius. I hope this is going to be a real cracker!
