Extreem weer in de VS verwacht

[Gert]

In de VS verwacht men dit weekend een situatie waarin supercellen kunnen ontstaan. Dit seizoen is tot nu toe zeer rustig op dit gebied. Hieronder informatie afkomstig van Weatherunderground

Weekend tornado and severe weather outbreak coming for the Plains
A significant multi-day severe weather event is expected Saturday, Sunday, and Monday across the Central U.S. A strong low pressure system will trundle slowly across the region, spawning supercell thunderstorms capable of generating large hail, damaging winds, and a few strong tornadoes. The action will begin Saturday afternoon along a swath from Central Texas northwards into Oklahoma and Kansas, then gradually shift eastwards on Sunday and Monday. Recent runs of the GFS and European model have been very consistent in showing moderate to extreme instability in the warm air ahead of the storm's cold front Saturday through Monday, and this weekend's severe weather outbreak has the potential to be the most dangerous one of this relatively quiet 2014. This year has yet to spawn a killer tornado, setting a new record for latest date of the year's first killer tornado. The previous record belonged to 2002, when the year's first killer tornado struck April 21 (an F-3 that killed a man in a mobile home in a rural area of Wayne County, Illinois.) The relatively cool and dry weather across Tornado Alley so far this year has led to no EF-3 or stronger tornadoes as of April 23, and that's also a record-long wait since modern tornado records began in 1950. According to tornado historian Tom Grazulis' book, Significant Tornadoes 1680-1991, "serious efforts" to document all tornadoes began in 1953, which was the first full year of tornado watches issued by the U.S. Weather Bureau, now the National Weather Service.

Interessant om te volgen dit weekend. Het is ook interessant om dat op het PING Project kanaal te doen.
