Feat happens at 2:19 and ends at 2:21 in which Rarity makes a massive storm all over Ponyville, well half of one that is. To find the size of the storm I'm going to try and find a size for Ponyville, and use that for my radius since the clouds go far behind Rarity as well. v
Size of Ponyville
Right, so the original method had been discarded as it was lowballing Rainbow's true speed. So I have to re-do the calc. Instead I'll be taking a timeframe based on Fluttershy, Twilight, and Spike walking from an unspecified location in Ponyville to Twilight's Library. It was afternoon when they began walking, and into Sundown by the time they got there. I've been told that 3 to 6 hours is a good assumption, so I'll be using these timeframes and a horses walking speed, which averages at 6.4 km/h according to this site.
Volume, Mass and Energy
3 * 6.4 = 19.2 km. Times that by 2 and you get 38.4 km for 6 hours. Since the clouds extended far behind Rarity, these will be used for my radius. The storm spread from Rarity to it's maximum in 2 seconds, so I'll cut the radius in half for my speed.
Like previously the area is 19200^2 * Pi = 1.15811672e9 m2 Multiplying by 0.5 due to the checkerboard pattern, granting an area of 579058360 m2
579058360 * 8000 = 4.63246688e12 m3. Multiplying by 1.003 to get 4.64636428e12 kg
0.5 * 4.64636428e12 * 9600^2 = 51.172195506.7 Gigatons
0.5 * 38400^2 * Pi = 2316233430 m2 * 8000 = 1.85298674e13 m3 * 1.003 = 1.8585457e13 kg
0.5 * 1.8585457e13 * 19200^2 = 818.755122 Gigatons
