After a moderately successful chase in the high plains on the 12th, another potential significant day followed. As a closed mid-level low rotated across Montana and Wyoming into the Northern Plains, a trough lagged behind that was forecast to move into the Dakotas during the evening on the 13th. At the surface, a low along the SD/NE border would drift east throughout the day while low 70 dewpoints advected into the warm sector in eastern South Dakota.

The 17th was day 1 of a 4 day chase excursion.

The plan was to play south-central South Dakota for the slight opportunity at supercells and maybe a tornado.

Ah, to be in South Dakota again! A strong trough was expected to move from the Rockies to the Northern Plains which would nudge the cold front eastward across the western Dakotas providing focus for storms to my north. Meanwhile a warm front draped from North Dakota down into Iowa and Missouri would provide a focus for storms to my east.  I opted to play the cold front as the warm sector would be flooded with ML CAPE near the 4,000 J/Kg range along with strong low level winds and curved hodographs would set the stage for a potentially decent severe weather threat.
