A small but potent closed upper level
low passed through the state overnight
and is now moving into western MN. This
was the storm system that brought the
severe weather to the area yesterday
evening. At the surface, a cold
front has swept through the state and is
now currently running north to south
over western MN. Winds across SD are out
of the west to northwest with
temperatures mainly in the 60s to lower
70s. There are a couple of lingering
showers over eastern SD but otherwise
skies are partly cloudy statewide.
Northwesterly winds are expected across
SD as the post-frontal airmass pushes
into the region. Speeds will be from
5-15 mph over eastern SD with 3-8 mph
winds over western SD. High temperatures
will reach the low to mid-80s with some
70s across the Black Hills. Showers and
thunderstorms are expected to redevelop
across western SD and the Black Hills
later this afternoon with thunderstorms
pushing eastward this evening and
overnight. There is a slight chance of a
few severe storms but they should not be
as potent as last night's storms were.
Minimum RHs will range from 25-35% West
River and from 35-50% East River.
Scattered showers and thunderstorms will
likely be ongoing tomorrow morning
across the state with more storms
developing in the afternoon. A few
stronger storms are possible but
widespread severe weather is unlikely.
Temperatures will be cooler with highs
in the 70s over much of SD although some
lower 80s are possible across the
southeast. Light and variable winds will
become northerly with time. Minimum RHs
will stay above 40% statewide.
No critical fire
weather is expected.
