Cumulus humillis

Cumulus with vertical growth

Fair weather clouds building up vertically often indicate cumulus congestus and cumulonimbus, which bring afternoon showers

Cumulus Congestus

Cumulus Congestus

Cloud tops forming altocumulus cumulogenitus usually bring precipitation in 5-10 hours including gusty winds, thundershowers and wind squalls

Cumulus Congestus

If clouds form from SW to NW, precipitation with gusty winds and thunderstorms or wind squalls are likely within 5 to 10 hours.

Cumulonimbus

Precipitation likely and soon coming usually from SW  W to N. Distant clouds often show an anvil-shaped cirroform cap

Cumulonimbus capillatus

Precipitation likely and soon coming usually from SW  W to N. Distant clouds often show an anvil-shaped cirroform cap

Cumulonimbus calvus

Precipitation likely and soon coming usually from SW  W to N. Distant clouds often show an anvil-shaped cirroform cap

Stratocumulus stratoformis

Immediate threat of bad weather from a sprinkle to heavy precipitation. If at head of a cold front - gusty winds or thundershower

Stratocumulus opacus

Immediate threat of bad weather from a sprinkle to heavy precipitation. If at head of cold front - gusty winds or thunder shower

Stratus

Winds from NE to S may bring heavy precipitation. Other winds may bring only a light drizzle or overcast sky

Cumulonimbus mamma

Seldom seen low to middle clouds associated with severe wind squalls, hail, heavy precipitation, tornadoes and thunderstorms

Nimbostratus

Rain or snow clouds. Precipitation of long duration if winds NE to S, or shorter duration if winds are SW W to N

Nimbostratus

Rain or snow clouds. Precipitation of long duration if winds NE to S, or shorter duration if winds are SW W to N

Cumulus
congestus fracto stratus
Precipitation of long duration if winds from NE to S, or shorter with other winds

Cumulus fractus

Fair weather clouds broken up by strong winds. No precipitation unless winds steady NE to S, then cumulus fractus indicates bad weather

Stratocumulus at sunset

Low water clouds of dark indian red color. Precipitation in 12 to 20 hours if winds from NE to S. Other winds bring overcast sky.

and Cirrus at sunset
Middle water to ice clouds with brilliant white background. Precipitation likely within 20 to 24 hours if winds are from NE E to S

Stratocumulus at sunset

Low to middle water clouds with gold, pink, amber, lavender or rosy background. No precipitation likely within 20 -24 hours
