Weather Summary - Shaun Tanner
Weather Underground Forecast for Thursday, June 15, 2006. What was tropical system Alberto will continue moving northeastward off the East Coast Thursday, providing some showers and thunderstorms to coastal areas of New England. But, by evening, the extratropical system will have moved significantly far enough to the north that this precipitation will have ceased.
A complex weather pattern will reside in the West, where most of the active weather for the day will occur. A strong trough of low pressure will remain over the Rockies and Great Basin through Thursday, and a low pressure system within the trough will move northward towards the Montana/Canada border.
Early in the day, showers and thunderstorms will develop in the Northern Plains and push eastward towards Minnesota. To the west, light rain will continue in the Intermountain West and Northwest as Pacific moisture continues to stream into the region.
In the afternoon and evening, another low will rotate around the trough, sparking a round of light to moderate rain accompanied by thunderstorms that will progress through the Southern Rockies and into the Central Plains. Daytime heating will also contribute to some shower and thunderstorm formation in the Southwest Thursday.
High pressure will keep much of the country from the Mississippi Valley eastward dry.
The Plains, Gulf Coast, and Southwest will be quite warm with highs in the 90s and 100s. The Northeast will be more mild as temperatures will warm into the 70s for most areas.
Temperatures in the Lower 48 states Wednesday ranged from a low of 27 degrees at Truckee, Calif. to a high of 111 degrees at Wink, Texas.

The tropics go quiet
Alberto has transitioned to a powerful extratropical storm over the Canadian Maritime provinces today, and no new threat areas have emerged over the Atlantic that look likely to become our next tropical storm--Beryl. Wind shear increased over the Caribbean last night, tearing apart two tropical waves that were producing some strong thunderstorms. The thunderstorm activity in the ITCZ off the coast of Africa remains disorganized. All of the global forecast models have...
Weather History
Did you know that...
The major Mount Pinatubo eruption of 1991 began on this date, hurling debris 100,000 feet into the atmosphere. The debris spread throughout the globe, partially blocking the sun's energy and cooling the average surface temperature by as much as 1 degree.
