Large hail again dominated the severe sector with the largest reported hail at 2.75 inches which occurred in Oklahoma. Damaging winds occurred all through this region with the strongest report coming out of Kansas with a wind gust near 80mph. Heavy rains hit Southern Florida associated with tropical moisture moving through the region.

Big Story Weather Discussion for May 30: High pressure off the Southeast Coast will again bring partly cloudy skies to the Southeast. Tropical moisture will be flowing into Florida again creating heavy rainfall for the region. Interaction between onshore flow and a frontal boundary to the west will bring showers and thunderstorms to the Gulf Coast. Severe weather is likely again today form Texas northward into the Northern Plains and Western Great Lakes. A nice day will setup over the West with plenty of sunshine.

Severe Weather: Today will be another large severe weather day with more tornadoes, large hail and damaging winds forecasted for our yellow box above. The strongest thunderstorms will be over the Central Plains from Kansas to Iowa and into Oklahoma. The severe weather from the Great Lakes and into the Ohio Valley will be mostly damaging winds.

A new frontal boundary will move into the Northern Rockies. Day five will have a strong frontal boundary moving through the Northern Plains bringing some severe weather and heavy rain to the region. Showers will still be along the East Coast, while tropical moisture moves into the Southwest Gulf. The period will finish with a low pressure over the Western Great Lakes bringing showers and thunderstorms from the Plains to the Ohio River Valley, and dry weather over the west. The tropical feature will be still over the Southwest Gulf during this time.

Day 8-12: The period will start with showers and thunderstorms extending from the Eastern Lakes to the Gulf Coast. Some severe weather will be possible. The tropical feature will remain in the Southwest Gulf. A dry day will be in store for the West.

Winds will also be increasing with the storm. Rain will extend across most of the East during this time as well. A new storm system will be developing over the Southern Plains. Day ten the tropical feature will make landfall in the US. A storm system pushing across the Northern Plains will bring showers to the region and will also pick up the tropical feature. Day eleven the tropical moisture will be moving up the East Coast, while another storm system moves into the Northern Plains bringing another round of severe weather to the Plains. The period will finish with the tropical moisture pushing into the Mid-Atlantic region.

Ask The Weatherman for May 30, 2013:

Question: What makes a super-cell thunderstorm so significant?

Answer: Super-cell thunderstorms are significant in the way they form, and also where they form. They need just the right amount of low level moisture, the right amount of dry air in the middle levels, the right amount of cold air from above, and a nice amount of spin in the atmosphere.
