Shifting Storm Clouds
Time lapse of dark storm clouds swirling over the Ipanema Beach skyline with tilt shift narrow focus along the shore in Rio de Janeiro, Brazil
Chaotic Sky. A night of squalls and wind shifts and clouds
Thunderstorms, low clouds, wind shifts, shear,rain, turbulence, brief clearing, frontal passages - all while you were sleeping.
Night Storm. Clouds build and boil with occasional flashes of lightning, followed by a brief heavy downpour of rain, and then partial clearing.

Cloud Slivers Shifting
Clouds Shifting Over Mountains
This outflow boundary gust front has traveled far from its parent storm. New storms often trigger along such boundaries and their wind shifts, strong gusts and temperature drops.
Classic roll cloud marking boundary of storm's cold air outflow
This roll cloud marking a thunderstorm outflow boundary is moving fast across the plains. New storms often trigger on such boundaries.
Lightning Storm. Frequent cloud-to-ground lightning strikes during a nocturnal thunderstorm in the Rapid City area.
The cold air outflow from an intense thunderstorm is marked by a shelf cloud, along with a strong wind shift and temperature drop once the surface gust front passes.
The threatening thunderstorm outflow boundary is a formation known as a shelf cloud. It marks a sudden wind shift, strong gusts, falling temperatures, heavy rain and hail.
A gust front from a departing thunderstorm spreads cooler air marked by a wind shift over an area much larger than the parent storm.
Rain descending into dry sub-cloud air produces strong, shifting winds at the surface
Streamers of rain and virga mark a plains storm with high cloud bases
Autumn Mountain Cloud Time Lapse Shifting Light
This gust front shelf cloud marks the outflow boundary of an intense High Plains thunderstorm.
A shelf cloud marks the outflow boundary of an approaching thunderstorm. Note the greenish sky color, often a sign of hail.
Roll cloud marking thunderstorm outflow boundary
A frontal passage rapidly lowers the cloud base, which then becomes obscured due to falling rain.
A brief spin up ahead of a gust front or rear flank downdraft in a supercell may have popped a brief funnel cloud.
The gust front of a severe thunderstorm approaches, bringing with it a wind shift, strong winds, heavy rain, hail and lightning.

These chasers found themselves chasing a massive shelf cloud marking the outflow boundary of a severe thunderstorm.
The ragged leading edge of the outflow boundary of a thunderstorm. Clouds tags provide evidence of the upward motions of warmer air being undercut by outflowing rain-cooled air.
The outflow boundary from a thunderstorm is about to bring a wind wind shift, turbulence, high winds and heavy rain.

Grey Clouds Swirling
In the western US, thunderstorms are a major ignition source of forest fires. This storm started a 7000 acre burn near Rapid City in 2012. The storm also helped to put out the blaze.
A high-based thunderstorm drops rain into a dry summer air mass, producing multiple microbursts. Strong shifting winds are a threat to aviation during takeoffs and landings.
All Hell Breaks Loose. A thunderstormy night wild wind shears, low clouds and frequent lightning.
Gust Front. Roll cloud marks a gust front, the outflowing boundary of the cold air produced by thunderstorm downdrafts
