...Heavy rain and a slight risk of severe weather is possible over the
Mississippi Valley into the Ohio Valley as a storm system develops over
the Middle of the country...
...Much cooler and windy weather is expected to move from the northern
Rockies across the Northern Plains toward the Midwest...
An area of one or more low pressure systems is expected to develop and
intensify as it moves from the Southern Plains northeastward toward the
Mid Mississippi Valley and Midwest. Moderate to heavy rain and embedded
thunderstorms are expected to occur with this storm system and affect the
Mississippi Valley as an associated cold front moves eastward. As low
pressure intensifies over the Midwest across the Great Lakes and southern
Canada, the heaviest rains will move northwest into western Ontario where
a change to snow is expected. However, as a strong cold front sweeps
eastward, showers and thunderstorms will move eastward across much of the
East Coast on Friday into early Saturday.
A mass of much cooler air will begin to sweep south and eastward from the
Northern Rockies starting on early Thursday and will continue south and
eastward into much of the Northern and Central Plains by early Friday.
Mostly light snow is expected to accompany this early season cold outbreak
from Montana into the mountains of Wyoming. This chilly air mass will
begin to follow the intensifying storm system and associated cold front
moving from the Midwest toward the East Coast on Friday into early
Saturday, bringing windy weather and quite cool temperatures into the Ohio
Valley and Appalachians by early Friday. Cool weather will cover much of
the East Coast into early Sunday as the cold front even sweeps southward
across much of Florida.
