Ranked by deaths, injuries, damage and size together.
- Hail in Alaska, June 22, 2007A thunderstorm produced very large hail in the Delta Junction area. A picture of the hailstones appeared in the online version of the local weekly paper the Delta Wind. Hail diameter was estimated from the picture. Unofficial reports noted the hail was golf-ball size.
- Hail in Alaska, July 6, 2005A very unstable atmosphere resulted in unusually severe thunderstorms over the south central region of Alaska from the central Kenai Peninsula north into the central Susitna Valley.
- Hail in Alaska, June 28 to 29, 2004These severe thunderstorm warnings were issued for uninhabited areas. Verification for this event is solely based upon examination of satellite and radar data that indicated hail near .75 inches in diameter.
- Hail in Alaska, July 9, 2005Thunderstorms formed along the Alaska Range and moved east intensifying to severe thunderstorms producing hail estimated around 0.75 inches. This occurred in a remote unpopulated area.
- Hail in Alaska, June 18, 2007A thunderstorm that formed along the Alaska Range blew up into a severe thunderstorm producing 1 inch hail as it moved through Paxson.
- Hail in Alaska, June 21, 2007Severe thunderstorms developed on the interior Kenai Peninsula. Spotter reports were of hail 1/2 to 3/4 inch and heavy rain with these Thunderstorms.
- Hail in Alaska, June 5 to 6, 2018A thermal trough lying across the Interior portion of the state extended towards Kuskokwim Delta and Bristol Bay. Abundant moisture at the surface combined with cold temperatures aloft to cause thunderstorms over the region.
- Hail in Alaska, June 15, 2005A strong thunderstorm moved off the Alaska Range and merged with a weaker thunderstorm that moved off the Talkeetna Mountains 10 miles east of Talkeetna.
- Hail in Alaska, June 14, 2005The Kenai radar indicated hail potential of 3/4 inch or more with this thunderstorm. This thunderstorm occurred over a relatively uninhabited region. A report was received from the Alaska Railroad that "ping-pong ball" size hail was observed near Curry.
- Hail in Alaska, May 23, 2010Hail up to 3/4 inch diameter reported by Co-operative Observer at 2030AKST.
- Hail in Alaska, June 2, 2010Hail of 0.75 in diameter was observed by a trained weather spotter 2 miles south of Fox.
- Hail in Alaska, June 8, 2010Hail reported by a Cooperative Observer, located just east of Fort Wainwright near Badger Road. The observer estimated a size of up to 1.25 inches, but no damage was reported to property or to vehicles parked outside. No other supporting reports nearby.
- Hail in Alaska, June 9, 2010A National Weather Service IMET observed hail up to 3/4 inch in diameter near Tok.
- Hail in Alaska, August 18, 2015Severe thunderstorms developed over the Matanuska and Susitna Valleys before moving over Cook Inlet and dying out. One storm over populated areas produced large hail.
- Hail in Alaska, June 11, 2024On July 11th, a number of thunderstorms developed over Interior, producing hail, gusty winds, and frequent lightning.
- Hail in Alaska, June 19, 2025After several days of summer heat across Alaska's interior, the upper ridge responsible for the heat shifted north allowing for a moist east and northeasterly flow to become established.
- Hail in Alaska, July 7, 2025An arctic trough dropped into northern Alaska and began to interact with a low-pressure system over the northern Gulf of Alaska. This allowed for a strong disturbance to advance northwest up the upper Tanana Valley right along the Alaska Highway.
