As of 1 AM CDT, temperatures around the region are in the mid 50s
with winds out of the northwest at about 10-15 mph. Some showers and
weak thunderstorms continue to move south out of North Dakota and
across northeast SD. These are expected to continue for a couple
more hours. Showers and weak thunderstorms return this evening into
the overnight hours across northeast SD. No severe weather is
expected at this time.

The rest of the work week looks to be quiet and dry with today
staying a little cooler. The next chance for widespread
precipitation is Saturday. Pops move into central SD Saturday
afternoon and spread northeast into portions of northeastern SD
through the evening. Some showers may linger into Sunday morning.
While our CWA is not currently in a severe outlook, there is
potential for some storms to become severe. The chance of more than
a quarter inch in accumulation is greater than 50% along and
southwest of a line from approximately Lemmon to Brookings. South
central SD has a 40 to 50% chance of more than an inch of
accumulation. 20-40% pops return most afternoons for the remainder
of the period as we move into a more active pattern.

Temperatures through the period continue to stay in the around to
slightly below average range. Today and Sunday look to be the
coolest at 10-15 degrees below average. Winds Friday between the
Missouri and James Rivers could gust to 35 mph along and behind a
cold front moving northwest to southeast across SD. Other than this
and some gusts of 25 to 30 mph west river Saturday, winds look to
stay below 25 mph through the period.
