towards the Hudson Bay. Chilly temperatures expected tonight with a few
areas in the Black Hills dipping into the 30s. Breezy westerly winds
expected on Wednesday with highs rebounding into the 80s on the

Drier west to northwest flow aloft will remain across
the region through much of the period. Warmer air will build into
the area late in the week...with temperatures back to near to above average
levels through the weekend. Any chances for showers and
thunderstorms through the weekend should mainly be confined to
southwest and south central South Dakota. The weather pattern could become at
least a bit more unsettled early next week as east to southeast
winds bring increasing moisture...and weak upper level disturbances
pass through the area.
