Hail can be detected using radar. On Doppler radar, hail generally sends a return signal that looks like extremely heavy rainfall. Dual-polarization radar technology, used by the NWS, can help tell the difference between hail, ice pellets and rain, and even determine hail size.

Formation. Hail forms in strong thunderstorm clouds, particularly those with intense updrafts, high liquid water content, great vertical extent, large water droplets, and where a good portion of the cloud layer is below freezing 0 °C (32 °F).

Yep, hail happens during the summer
In fact, most precipitation — including the rain that falls in the tropics — actually begins as snow up in the clouds, and only melts into rain when it falls below the freezing line.
Can you hail when its cold?
Hail forms when low pressure is formed at the surface of the earth. This low pressure moves upwards, dispelling ice crystals until they are heavy enough to fall. It is the non-occurrence of low pressures at the surface which make it a reason that hail in winter is impossible.
Why is there hail in summer?
Hail is most common in mid-latitudes during early summer where surface temperatures are warm enough to promote the instability associated with strong thunderstorms, but the upper atmosphere is still cool enough to support ice.
