Weather Underground Forecast for Monday, August 06, 2012.

Unsettled weather will continue in the Eastern Seaboard on Monday, while fire weather conditions persist in areas of the West.

In the East, the northern half of a cold front in the Midwest will advance across the New England coast by the afternoon, while the southern half of this disturbance stalls from the Mid-Atlantic through the Southern Plains. Instability ahead of front will translate into areas of scattered showers, periods of heavy rainfall, and thunderstorms from New England through the Southeast. Expect cooler and drier conditions to return to areas behind the cold front as the disturbance departs and high pressure spreads into the Northeast. Meanwhile, showers and thunderstorms will continue in the Southeast through the beginning of the work week and will become enhanced by a wave of energy in the northern Gulf of Mexico.

In the Plains, hot temperatures are anticipated across much of the region with daytimes ranging from the upper 80s in the Northern Plains to lower 100s in the Southern Plains. Expect high fire danger conditions in parts of the Central Plains as a weak frontal system moves into the area with possible dry lightning as isolated to scattered thunderstorms develop during the late afternoon.

In the West, chances of showers and thunderstorms will continue in the Central and Southern Rockies and across the Central Great Basin due to monsoonal moisture and weak disturbances passing through these areas. Meanwhile, a mix of wet and dry, isolated to scattered thunderstorms are anticipated in much of the northwestern quadrant of the nation. This activity combined with gusty winds and low relative humidity levels may translate into fire weather conditions from the afternoon through the evening. Temperatures in the Lower 48 states Sunday have ranged from a morning low of 30 degrees at West Yellowstone, Mont. to a high of 105 degrees at Needles, Calif.
