With most of Minnesota experiencing below-normal values for precipitation in the month of June, rain returned on June 14-15 with a heavy dose being dumped across southwestern parts of the state.
Many locations in southern Minnesota reported from one to two inches of rain that fell between June 14-15 with Comfrey in Brown County reporting the most rain at 4.70 inches.
A surface trough extending off of a low pressure system in Iowa crept across Minnesota starting late Tuesday night and finally moved away by Wednesday evening. An upper level shortwave trough, which eventually closed off, provided significant lift to develop the storms. Steep mid level lapse rates and large amounts of moisture also played a large role in contributing to the heavy rain.
The extent of the storms consisted of mostly heavy rain with occasional lightning, however there was half inch hail reported at Ellendale in Steele County, Wednesday afternoon.
While the heavy rain brought bad news for outdoor baseball on Tuesday for the Twins, the rain was welcomed in central Minnesota, where very little rain had fallen during the first two weeks of June. In southwest Minnesota it was too much rain for farmers with soggy fields.
