Strong Thunderstorm hits my location & Southeast Polk County with very heavy rain, strong winds, and hail, Warning Issued.

Shelf Cloud from a Strong Thunderstorms which later impacted my house.

After a Hot and very Humid afternoon, Strong Thunderstorms hit parts of the area this, Especially in Northern St Croix County and Southeast Polk County, where this storm impacted me.
Snapped Radar Image just before the heaviest band of rain hit my location.

Following the St Croix/Polk County storm in particular, it first started out in Northern St Croix County, it then crossed into Polk County, and moved Northeast following a stationary front. This storm really started to get together and become strong as it approached Clayton, At one point the radar was detecting possibly over 1 inch sized hail, This is when the NWS Issued a Severe Thunderstorm Warning for Clayton and the surrounding areas. but shortly after the storm weakened some. Other heavy thunderstorms hit Eastern Barron County and parts of Dunn County, There were no severe weather reports from any of the area, including southeast Polk County.


Effects that this storm had at my location.





Video of the Strong Winds from my Front Yard July 7th.

The storm hit me just before 6PM, about 5 minutes before the storm hit the NWS issued a Severe Thunderstorm Warning for my area. This storm, although not reaching severe limits severe was definitely a notability strong one in my book. A well formed shelf cloud could be seen for miles before it hit, the clouds went very fast from west to east. The rain was so heavy I actually could see the sheet of heavy rain moving down the county blocks southwest of my house in the distance. First came strong WSW winds, and extremely heavy rain, My field wind gauge clocked in a 27MPH gust. (This was about the time I took the video above) After the winds slowed the hail started, which came in 2 waves that didn't last very long. The hail was mainly pea sized, but some of it was just under the size of dimes, There was some damage to some of my garden plants, but nothing significant was done. This storm also came with frequent dangerous lightning, one bolt was extremely close, and had very loud thunder, enough that it shook the house and rattled the windows. I estimated the bolt hit a tree in the woods just across a thin field to my south, which is about quarter mile away! This storm also dropped a very heavy amount of rain in a short time, I picked up a quick 0.63" of rain, which fell with in a 10 to 15 minute time span! I was so heavy that our driveway had ruts carved down it. This storm was the strongest to impact me so far this year, and will be one to remember.

This storm brings my monthly total to over 2 inches, My confidence is getting higher that we will soon be completely drought free!
