The nation’s weather

Weather Underground midday recap for Sunday, June 02, 2013.

Showers and thunderstorms continued in the Eastern Seaboard on Sunday as a strong cold front reached from the Northeast, down the East Coast, and across the Deep South into Texas on Sunday. The low pressure system that pushed the cold front eastward lifted northeastward from the Great Lakes and into eastern Canada. This transition allowed for shower and thunderstorm activity to diminish across the Great Lakes, but move into eastern Canada and the Northeast. As the cold front reached across the East, it tapped into moisture and energy from both the Gulf of Mexico and the Atlantic Ocean, allowing bands of showers and thunderstorms to develop from Maine through Florida and the Gulf coast. Some of these storms had the potential to turn severe with primary threats of strong winds, large hail, and heavy rainfall. Favorable low level conditions also allowed for a weak tornado threat to develop mainly from northern Maine through northern New Hampshire. Flooding was also a concern, especially in already well saturated areas of these regions. Many areas experienced about 1 to 2 inches of rain by Sunday afternoon. As of this afternoon, there have been several reports of quarter to ping pong ball sized hail (1.00 to 1.50 inches in diameter) in western Virginia, western New York, and Vermont. High wind events with downed trees and wires were also reported in New England.

Behind this system in the West, a low pressure system moved over the Pacific Northwest on Sunday, bringing showers and thunderstorms to the Northwestern corner of the nation. At the same time to the south, a trough of low pressure moved northward from Mexico, kicking up showers and thunderstorms across New Mexico and western Texas. Strong storms in these areas created a marginal threat of severe storms with hail and damaging wind gusts.

Temperatures in the Lower 48 states Sunday have ranged from a morning low of 26 degrees at West Yellowstone, Mont. to a midday high of 102 degrees at Casa Grande, Ariz.
