This morning, just after sunrise, a pocket of thundershowers made its way across the northern third of New Brunswick.  The storms were isolated and even if you live in that area, you may or may not have noticed anything, 

Lissa Bordage was sitting at her kitchen table in Rogersville New Brunswick around 7:30 this morning when she and her daughter noticed something, but it wasn’t the thunderstorm itself.  The photo Lissa sent shows a classic roll cloud!  Lissa wrote: "The cloud looked like it was rotating then it got dark out and the wind picked up, it lasted a few minutes then it went away".  Great description; thankfully, it looks more threatening than it actually is.

A roll cloud is a relatively rare, low-level horizontal, tube-shaped accessory cloud completely detached from the cumulonimbus or thunderstorm base.  When present, it’s located along the gust front and most frequently observed on the leading edge of a line of thunderstorms. It can however materialize along a cold front that is travelling through with no thunderstorms. The roll cloud will appear to be slowly "rolling" along its horizontal axis.

Comments that often accompany the cylindrical cloud indicate that it looks like a tornado on its side, while others claim the cloud appears to roll like a rolling pin.  All very accurate!  

Roll clouds are not and do not produce tornadoes.

You’ll never know what you’re missing if you don’t look up!
