The combination of the circulation around an old storm and moisture from the Great Lakes will produce bands of flurries and heavier snow Wednesday over the interior Northeast. Some periodic snow is also expected southeast of Lakes Michigan and Superior. No significant snow showers are in the forecast for the coastal Northeast. A southern dip in the jet stream will bring unseasonably cold conditions to much of the East.
Snow and a wintry mix will dip south across the northern Plains. Enough snow may fall to produce slippery travel conditions in parts of the Dakotas, Iowa and Minnesota. Snow will blanket parts of the northern Rockies. Most areas from the Deep South to the interior Southwest can expect a dry day, with sunshine.
The latest in a series of storms from the Pacific Ocean is expected to bring wet weather from western Washington to Central California. Rain will spread to Southern California on Thursday. Enough rain may fall to cause mudslides and flash flooding, especially in recent burn areas. Any snowfall should be restricted to above pass levels in the Cascades and the northern Sierra Nevada, but freezing levels are projected to lower on Thursday, which could cause wintry and slippery travel conditions in the passes.
FOCUS: Pattern Change Early Next Week
Cold air is expected to move into the Western U.S. early next week, which may result in snow from the Rockies to the northern Plains. In the East, a southwest breeze will bring milder air all the way up into New England.
