Tornado

Tornado: A violently rotating column of air extending from a thunderstorm cloud to the ground. The Enhanced Fujita Tornado Intensity Scale is used to categorize tornadoes

Funnel Cloud: A condensation funnel extending from the base of a towering cumulus or cumulonimbus, associated with a rotating column of air that is not in contact with the ground (and hence different from a tornado). A condensation funnel is a tornado, not a funnel cloud, if either a) it is in contact with the ground or b) a debris cloud or dust whirl is visible beneath it.

Small limbs down (less than 2" in diameter)
Large limbs/branches down (more than 2" in diameter)
Trees snapped or uprooted

Pea Size: 0.25 inches
Small Marble: 0.50 inches
Penny: 0.75 inches
Nickel: 0.88 inches

Heavy Rain

How much rain fell, e.g. 1.50".
What period of time did the rain fall? (e.g. 1 hour 15 minutes.)
Was the rainfall measurement estimated or measured with equipment?

Snow Info

How much snow fell (to nearest tenth of an inch if possible), e.g. 3.5".
What period of time did the snow fall? (e.g. 1 hour 15 minutes.)
Was the snowfall measurement estimated or measured?

Freezing Rain/Icing

How much icing was observed (to nearest tenth of an inch if possible), e.g. 0.5".
What period of time did the ice accumulate? (e.g. 2 hours 30 minutes.)
Was the rainfall measurement estimated or measured?

Strong Winds

We are generally interested in wind speeds of 40-50 mph or higher. Here is some info on how to estimate wind speeds:

39-54 mph: Twigs break off trees; wind generally impedes progress.
55-72 mph: Damage to chimneys and TV antennas; pushes over shallow rooted trees.
73-112 mph: Peels surfaces off roofs; windows broken; light mobile homes pushed or overturned; moving cars pushed off road.

Dense Fog

We are mainly interested in visibility reports of a half mile or less.
