Weather Underground Forecast for Friday, June 28, 2013.
Wet weather will continue for the East on Friday, while rain showers finally end across the Pacific Northwest. A broad low pressure system moves over the Northeast and flow around the system creates a strong cold front that stretches down the East Coast and into the Southeast. This system will allow for showers and thunderstorms to develop across the region throughout the day. Some of these storms will turn severe with strong winds and large hail. At the same time a warm front develops along the northeastern side of this system, bringing heavy rains to the far Northeast from Vermont and New Hampshire through Maine. Lighter and more widespread showers and thunderstorms will continue along the back side of this system from the Great Lakes through the Midwest and Mid-Mississippi River Valley. Thus, flooding will remain a concern for parts of the Midwest and Northeast on Friday.
Out West, hot temperatures are anticipated across the Desert Southwest and spreading northward across the Western states as high pressure continues building northward. This will create warm, dry, and sunny conditions for most of the West, allowing for showers to end for the Pacific Northwest. Excessive heat advisories have been issued for Arizona, New Mexico, Nevada, and southern and central California as high temperatures may reach over 110 degrees for the desert locations.
Temperatures in the Lower 48 states Thursday have ranged from a morning low of 37 degrees at West Yellowstone, Mont. to a high of 105 degrees at Needles, Calif.
