OCR Text	Show Know The Weather Why is it said that lightning is caused by updrafts? Is that true? FIRST, IT'S true that updrafts are the cause of lightning. So that's why this statement is heard. Warm updrafts are the most usual producers of this spring's light-noise electrical discharge. Warm air rises and when it rises fast, and cools quickly, it builds up an electrical charge, which is eventually dissipated with a flash and a bang. The cumulonimbus (thunderhead) cloud is the source of strong updrafts and lightning and thunder. AFTER THE first big drops, then the heavy rain, and after the low, dark leading lead-ing edge of this giant cloud passes above you, at that time the danger of lightning striking you op the ground is greatest.
