The nation’s weather
Weather Underground Forecast for Friday, May 06, 2016
A low pressure system will move across the Southwest on Friday, while a separate system shifts over the East Coast.
A low pressure system will move slowly eastward across the Southwest. This system will produce widespread showers and thunderstorms across the Pacific Northwest, the Southwest and the Intermountain West. Prolonged heavy rain will bring threats of flash flooding to northeast Utah, southeast Idaho, northwest Colorado, Wyoming and southeast Montana. High elevation snow is also expected for the Sierra Nevada, the Wasatch and the Rockies. Flash flood watches are in effect for northern California, central Oregon and northeast Oregon.
Just to the east, a cold frontal system will dip southeastward over the northern Plains and the upper Midwest. This system will initiate showers and thunderstorms across parts of the northern Plains, the upper Mississippi Valley and the Great Lakes.
Meanwhile, a pair of low pressure systems will develop over the East Coast. The first system will drift northeastward over northern New England and southeast Canada. Moderate to heavy rain will accompany this system, affecting most of Maine. To the south, another area of low pressure will generate rain and embedded thunderstorms across the Mid-Atlantic, the central Appalachians and southern New England. High pressure will bring warm and dry weather to the central and southern Plains, as well as the middle and lower Mississippi Valley.
Temperatures in the Lower 48 states Thursday have ranged from a morning low of 24 degrees at Land O, Wis. to a high of 95 degrees at Goodyear, Ariz.
