"WEATHER PHENOMENA"

Id Have To Think That Most Of You Will Not Have A Clue As To What Im Talking About....But Then again...People From All Over The World Will Be Reading This.....Because Ive Talked With Numerous People Here In The USA..And Nobody Seems To Know What Im Asking About
Ive Even Gone On The Internet And Have Not Found Anything That Pertains directly To What Im Talking About
But Im Sure There Are Others Somewhere In This World That Have Witnessed The Same Thing
I Cant Even Find A Name For It
Heres What Happened Some Years ago

It Was During The 4th Of July...(And During The Afternoon) (Thats When America Celebrates Its Independence)(Also ..Its Summer Time)
During This Time Its Not Unusual To Be Hearing The Sound Of Fireworks Coming From A Distance ...Where People Could Be Shooting Off Fireworks Or Setting Fire Crackers Cherry Bombs..Or Blockbusters
On This Day I Could Hear(In The Distance)The Sound Of Loud Bangs
One After Another..Or Boom..Ba Boom..Ba Boom Boom...And Each Time..The Sounds Were Separate Or... One Right After Another..Or All Together
I Thought To Myself
"Boy..Somebody Spent A lot Of Money... To Be Setting Those Things Off"..And I Thought..."Why During The Day?"
And Then I Went Outside Just For The Hell Of It
It Was Then I Realized It Wasnt People Setting Off Fireworks
There Was A Line Of Black Clouds Coming My Way
And The Sound Was Being Emitted From The Clouds
If One Didnt Know Where The Sound Was Coming From..One Wouldve Thought... He Was In A War Zone
But... It Was Only A Storm Producing The Sound
Its The First Time Ive Ever Witnessed This "Cannon" Type Sound
And It Was The Last Time Also
I Would Think Its Very Rare
But Knowing People From All Over The World Over The World Might Be Reading This
And...Is There Even A Name For This Type Of Thunder?
Maybe Theres Others Who Have Heard This Rarity Also
