 An area of low pressure over the Great Lakes will continue moving eastward over the Northeast. At the same time, flow from the South will continue pulling moisture in from the Gulf of Mexico. This will allow for more scattered showers and thunderstorms to develop over the Northeast, Ohio River Valley and
eastern valleys. Some of these storms may turn severe with strong winds and large hail.
Meanwhile, out West, another storm system approaches the West Coast from the Pacific Northwest. The system that brought rain and snow to the West Coast on Thursday will move eastward into the Rocky Mountains as the next system moves onshore. This will allow for rain and high-elevation snow to develop from the Pacific Northwest and northern California, through the Intermountain West and
northern Rockies. Snow will be heavy at times, with accumulations ranging from 8 to 12 inches in the
northern Sierras and 4 to 7 inches in the northern Rockies. The Cascades will see another 2 to 4 inches of snow by Friday evening. Strong winds will accompany this system, with gusts up to 50 mph at highest mountain passes.
In the central U.S., record-breaking high temperatures will continue on Friday as warm air continues to pour in from the South. Expect temperatures to range between 15 to 25 degrees above seasonable across the Plains. The
northern Plains and upper Midwest will reach into the 70s, while the southern Plains will remain in the 80s.
Temperatures in the Lower 48 states Thursday ranged from a morning low of 12 degrees at Alamosa, Colo., to a high of 89 degrees at Bainbridge, Ga.
