This Hazardous Weather Outlook is for south central South Dakota.
.DAY ONE...Tonight.
No hazardous expected at this time.
.DAYS TWO THROUGH SEVEN...Tuesday through Sunday.
Confidence is high in strong winds impacting the area Tuesday
afternoon through Wednesday morning. Wind gusts of 50-60 mph are
expected. Blowing and drifting snow will not be as much of a risk due
to lack of snowpack. However, what snow is on the ground could blow
around creating temporary reductions in visibility. A High Wind
Warning is in effect from Noon Tuesday until 4 AM Wednesday. Winds
will gradually taper off through the rest of Wednesday.
Beginning Thursday snow chances will return and persist throughout
the rest of the week and weekend. Currently snowfall totals look to
remain light.
Cool temperatures for Wednesday and Thursday, followed by much
colder Arctic air for the weekend. Cold weather headlines may be
needed.
