On Saturday into Sunday, a cold front moves off the East and Gulf Coasts,
followed by an area of cold high pressure over the Plains and Ohio Valley.
The high pressure will bring temperatures 20 to 25 degrees below average
over the Upper/Middle Mississippi Valley and the Ohio Valley. The low
temperatures will drop well below 0ĀF, with afternoon highs remaining in
the single digits. Additionally, upper-level energy will produce heavy
snow over parts of the Ohio Valley, the UP of Michigan/northern LP
Michigan, and the Lakes Erie/Ontario coastline, starting late Saturday
night into Sunday, as moderate to heavy snow falls over the Mid-Atlantic.
See the WPC Heavy Snow Discussion for details and amounts. From Sunday
into Monday, lake-effect/lake-enhanced snow will develop downwind from the
Great Lakes.
Meanwhile, as the front moves over the Gulf Coast States, rain and
showers/thunderstorms will develop over the area from Saturday into Sunday
afternoon. In addition, light rain will develop over the southern
Mid-Atlantic/Southeast. Lastly, onshore flow returns to the Pacific
Northwest, producing rain over the area on Sunday and heavy rain overnight
Sunday into Monday.
