DENVER (CBS4)– The National Weather Service radar picked up something unusual on Tuesday, it wasn’t snow or rain but a flock of migrating birds. Actually, it came out on Wednesday that the blob was a bunch of migrating butterflies!
The radar showed a big blob over parts of Colorado which wasn’t a storm but a mass of migrating birds, butterflies or black birds.
Some speculate that the blob is witches getting ready for Halloween.
On Wednesday, the National Weather Service tweeted out that what was picked up on radar was actually butterflies. The Painted Lady butterflies are moving through Colorado on their way to Arizona, New Mexico and northwestern Mexico to enjoy the Southwest winter.
