Weather Underground Forecast for Tuesday, Jan. 21, 2014
A cold frontal boundary will move off of the Eastern Seaboard on Tuesday, while a separate cold front will push across the Southeast.
A cold frontal boundary will drive a swath of heavy snow across the East Coast on Tuesday, as heavy snow showers will extend from North Carolina to Maine. Lighter snow showers will also develop across the Mid-Atlantic and the eastern Great Lakes, while heavy snow will also be possible in northern Illinois and southwestern Michigan. Spotty snow showers will linger across the upper Midwest during Tuesday morning. Meanwhile, a separate cold front will extend from the central Gulf Coast to South Carolina, as showers will be possible across the Gulf Coast and Florida. Just to the west, a high pressure system will build over the southern Plains, providing warm, dry conditions to the region.
Another frontal boundary is forecast to extend across the Intermountain West on Tuesday, as snowy weather will move over the northern Rockies. Light rain will move into western Washington and northwestern Oregon due to an onshore flow from the Pacific. The rest of the West Coast will stay clear of precipitation as a ridge of high pressure parks itself over the eastern Pacific. This high pressure will prolong drought conditions across California.
Temperatures in the Lower 48 states Monday have ranged from a morning low of -16 degrees at Grand Marais Airport, Minn. to a high of 82 degrees at Kingsville NAS, Texas
