Two periods of strong winds affected Southcentral and Southeast Wisconsin as a deep surface low tracked from southern Minnesota into northern Wisconsin during the overnight hours of April 15th to 16th.  Southerly winds gusting to between 45 mph and 54 mph (39 knots to 47 knots) affected South Central Wisconsin on the night of the 15th with the tightening pressure gradient ahead of the low.  The winds were enhanced with strong low-level jet winds mixing down to the surface.  Cold-air advection, behind a cold front trailing the low, crossed the region during the day on the 16th and brought sustained winds between 20 mph and 30 mph (17 knots to 26 knots) and gusts up to 49 mph (43 knots) to much of South Central and Southeast Wisconsin.  There were multiple reports of downed power lines, trees and tree branches.
