Hail is possible within most thunderstorms (as it is produced by cumulonimbus), [4] as well as within 2 nmi (3.7 km) of the parent storm. Hail formation requires environments of strong, upward motion of air within the parent thunderstorm (similar to tornadoes) and lowered heights of the freezing level.
Hail can cause serious damage, notably to automobiles, aircraft, skylights, glass-roofed structures, livestock, and most commonly, farmers' crops. [67] Hail is one of the most significant thunderstorm hazards to aircraft. When hail stones exceed 13 millimetres (0.5 in) in diameter, planes can be seriously damaged within seconds. [68]
The rear flank downdraft can arise owing to negative buoyancy, which can be generated by cold anomalies produced at the rear of the supercell thunderstorm by evaporative cooling of precipitation or hail melting, or injection of dry and cooler air in the cloud, and by vertical perturbation pressure gradients that can arise from vertical gradients of vertical vorticity, stagnation of ...
Hail is a type of frozen precipitation that forms during thunderstorms, typically in the spring and summer months in the U.S. Facts about hail, the icy precipitation often encountered in spring ...
Hail approximately 2.5 inches hit communities in Florida, according to CNN. ... Severe thunderstorms were also reported in the region, according to the National Weather Service in Miami.
An unusually strong storm blanketed a large portion of the northeast Denver metro area in the late evening. Golf ball-sized stones damaged homes and vehicles, in an event comparable to the May 2017 hail storm. Due to the late hour the storm hit, much of the hail would not melt until the following day.

The storms are packing wind gusts of up to 65 mph and golf-ball-sized hail (1.75 inches). "At 8:16 p.m., a severe thunderstorm was located over Mansfield, moving south at 15 mph," states the NWS ...
In Canada, a severe thunderstorm is defined as having wind gusts of greater than 90 km/h (56 mph), hail with a diameter of greater than two centimetres (0.79 in), rainfall rates of greater than 50 millimetres (2.0 in) in one hour or greater than 75 millimetres (3.0 in) in three hours, or tornadoes.
