Billowy Billows
White Fluffy Pillows
Puffy or Flat
Misty Zeppelins
Blanketing Overhead
Cumulus's Fluff
Can Make For Wet Weather
Nebulous's Haze

Stratus's Layers
Lay Near to the Earth
Veteran Sailors
Give Nimbostratus Wide Berth
Cumulonimbus's High Thunderheads
Pay Homage to a Norse God
Whose Lightning Bolts
Evoke Approbation
And Remaining Outdoors
Requires Grave Consideration
