During the morning of Monday, August, 5th, thunderstorms were moving across central Minnesota ahead of a cold front moving southeast. By the late morning, and early afternoon, thunderstorms developed west of the Twin Cities metro area and quickly became severe. Very large hail occurred with these storms, with numerous reports of golf ball size hail. The largest hail stone was near Delano with a measurement of 4 inches in diameter. Damage was extensive along the swath of hail. A special midday upper air sounding was launched and indicated a very high chance of large hail stones. Bulk wind shear parameters of 45 knots and MLCAPES of 3000 J/Kg were adequate to produce these types of large hail stones.
A secondary line of storms developed during the afternoon northwest of the Twin Cities. These storms produced up to 3 inch diameter hail in Anoka County. As the storms moved farther to the southeast, isolated severe hail stones occurred and wind damage was reported.
