Severe Weather Outbreak Likely

A significant severe weather outbreak appears to be likely across eastern North Dakota and northwestern Minnesota this afternoon into the morning hours of Wednesday.  This severe weather outbreak has the potential to produce strong straight line thunderstorm wind gusts over a large area, very large hail, and a few tornadoes.  In addition, areas of heavy rainfall and localized flash flooding will be possible. 

An unusally strong upper level low pressure center, for this time of year, is currently moving eastward across southwestern Canada, near the international border.  A complex surface frontal system is tracking eastward across the Dakotas.  Ahead of the frontal system, strong southerly winds near the surface will allow abundant moisture from the gulf of Mexico to be drawn into the system.  The strong directional turning of winds in the lower portion of the atmosphere will allow rotating supercell thunderstorms to develop with the potential to form tornadoes.
