Issue Date: July 5, 2018
Tornado warnings on telephones and weather radios in much of TIMESland were advising people to take cover early Sunday afternoon, July 1. In Crivitz the tornado warning sirens began blowing at about 12:24 p.m.
A mild tornado did strike in Shawano County, but according to the National Weather Service the storms that struck parts of central Marinette and Oconto counties and caused property damage in Crooked Lake were straight line winds and thunder storms, with no actual tornados reported.
National Weather Service reported that scattered thunderstorms, some severe, developed ahead of a cold front that moved into a very warm and humid air mass across central and northeast Wisconsin. The strongest storms produced "wet microbursts" that resulted in winds over 75 mph and large hail.
Many dozens of trees were uprooted or snapped across the hardest hit areas. Six buildings sustained at least minor damage from fallen trees in the Mountain area of Oconto County.
Rainfall rates of over 2 inches per hour were reported with the strongest storms.
Winds speeds were recorded at 70-80 miles per hour. There were brief power interruptions but few widespread power outages were reported.
Some warnings issued for the Crivitz area advised people to take cover, and said a tornado had been sighted, and was due to hit Crivitz at 1:15 p.m.
Observers said the downpour in Crivitz did start at almost exactly 1:15, with winds blowing straight in from the west, then from the north, then from the south, and then all over again. Winds speeds were recorded at 70-80 miles per hour in some areas, and one-inch hail was reported in Wausaukee and in the High Falls area of the Town of Stephenson west of Crivitz.
In the Crooked Lake area downed trees blocked roads and fell on at least six buildings and one vehicle. There were no reports of injuries.
A report from Crooked Lake said first it was just raining there, "then came the downpour, and then suddenly everything was twirling, a chair went flying over and trees went down." At least one camper window was broken.A portion of County Highway W, which goes through Crooked Lake and on toward Crivitz had to be shut down while crews cleaned up debris.
Wisconsin Public Service reported more than 4,100 customers without power at 4 p.m. About 1,800 of those outages were in the Crivitz area. Trees were down in the area of 141 and JJ in Marinette County. Peshtigo and Marinette areas reported thunder, lightning, heavy rains and strong winds, but no storm damage.
