The nation's weather
Weather Underground Forecast for Friday, June 29, 2012.
The Eastern half of the nation will see another hot day on Friday as a ridge of high pressure continues pushing warm and moist air in from the Gulf of Mexico. Excessive heat warnings and heat advisories will remain in effect for the Midwest, as well as the Central and Southern Plains, and have been issued for parts of the Northeast and Mid-Atlantic states. High temperatures will remain in the lower 100s for these areas, which are about 10 degrees above seasonable for most areas. Meanwhile, a cold front moves over the Great Lakes and into the Northeast on Friday. This system will kick up scattered showers and thunderstorms from the Northeast and down the Ohio River Valley. These storms are not expected to turn severe and this front will bring little relief to the hot temperatures for the region.
Meanwhile, in the West, monsoonal moisture will create more showers and thunderstorms across the Southwest, Great Basin, and Central Rockies. High pressure over the region will keep the surface warm and dry, thus, significant rainfall is not likely. However, this will increase the risk of dry lightning, thus, fire danger will remain high for the Southwest, Great Basin, Central Rockies, and parts of southern California. In the Pacific Northwest, a trough of low pressure dips in from the Gulf of Alaska, and pushes a cold front onshore. This will produce scattered showers across Washington and Oregon throughout the day. Temperatures in the Lower 48 states Thursday have ranged from a morning low of 28 degrees at Stanley, Idaho to a high of 106 degrees at Needles, Calif.
