Arctic cold continues its hold across much of the nation. Temperatures across much of ND and northern MN remain -15 to -20 and subfreezing temperatures stretch from northern TX into northern AR, along the OH River, across western PA and into New England. This will aid in setting up the next major winter event mainly along and north of I-80 from NE into OH on Thursday and across PA into New England on Friday. This will be in response to another storm system moving out of the Rockies and tracking eastward near a path along I-70 from CO to MD.
This storm system will deliver more significant snow for many in the northern ¼ of the nation from the Plains through the Great Lakes and into New England. There will also be a band of freezing rain/ice mainly along the I-80 corridor from NE into PA. Southward, rain and rain showers will occur. In advance of this system, temperatures will warm, especially across the southern third of the nation.
