...Light Snows Possible Saturday Into Saturday Evening...

Arctic air will surge through the area late tonight through
Friday. Meanwhile, an upper level disturbance will drop
southeastward into the region, bringing a good chance of some
light snow to much of the region Saturday into Saturday evening.
If temperatures can warm into the middle or upper 30s the snow may
mix with or change to rain over portions of the region in the
afternoon.

Relatively warm ground and road conditions along with
temperatures hovering around or just above freezing should
minimize travel impacts through the day. However, if the snow
comes down hard at times, or if snow lasts much past sunset when
temperatures fall into the 20s for good, there could be some
impacts, especially on elevated roadways. All precipitation should
exit the region by midnight.

...Strong to Severe Storms expected to move into Southeast
Missouri between 5 pm and 6 pm CST...

Severe thunderstorms across West and South Central Missouri were
beginning to accelerate toward Southeast Missouri this afternoon.

These thunderstorms are starting to group together into a small
line...currently moving southeast near 50 mph. Although hail will
be a hazard, a more widespread swath of damaging straight line
winds, exceeding 70 mph at times, will be possible from the late
afternoon and into the early evening.

The leading edge of the storms could reach the western border of
Wayne and Carter Counties between 5 pm and 515 pm CST.

These storms will likely intensify and accelerate further as the
move into Southeast Missouri, possibly reaching near a Cairo
Illinois to New Madrid Missouri line near 7 pm CST.

If you live or are planning travel into Southeast Missouri late
this afternoon and through sunset, be prepared to seek shelter
when threatening storms approach your area.

The strong storms may work into parts of extreme Southwest and
Southern Illinois during the evening. These storms will likely
work move into the Purchase area of West Kentucky after dark.

Stay tuned and monitor to NOAA Weather Radio, commercial
television and radio, social media, and mobile devices for the
latest watches, warnings, and statements.
