The nation's weather

Weather Underground Forecast for Tuesday, June 05, 2012.

Showers and thunderstorms will move into the Northern Rockies on Tuesday, and persist across the Southeast. A low pressure system and associated cold front continues moving eastward over the Pacific Northwest and into the Rocky Mountains. Flow around this system pulls more moisture onshore from the Pacific Ocean, thus triggering widespread showers and thunderstorms across the Intermountain West, as well as the Northern Rockies. There is a slight risk of severe weather development for the region with strong winds, large hail, and heavy downpours remaining the greatest concern. The tail end of this cold front will extend southward through the Great Basin. Strong and gusty winds ahead of this frontal boundary will keep fire danger high due to prevailing hot and dry conditions across the Great Basin and Southwestern US. Rain showers should diminish for northern California as high pressure builds in from the south, but expect widespread rain showers to persist for the Pacific Northwest.

Meanwhile in the East, an area of low pressure in the Northeast finally pulls offshore and allows for sunny skies and dry conditions to return. However in the Southeast, a trough of low pressure moves eastward from the Southern Plains and pulls warm and humid air onshore from the Gulf of Mexico. This will support more showers and thunderstorms across the Gulf states, some of which may turn severe with strong winds and large hail. Temperatures in the Lower 48 states Monday have ranged from a morning low of 28 degrees at Mt. Washington, N.H. to a high of 96 degrees at Pecos, Texas
