09/11/00 Storm Chase in WI and IL


Small, non-rotating wall cloud near Belmont, WI.

Composite view looking WSW at a rotating tail-end Charlie entering Grant Cty. WI.

Later view of same storm now beginning to split.

 

The right mover with a very laminar inflow band.

Another view of this small, yet impressive storm.  It went SVR shortly after this image producing golfball size hail

Base reflectivity at 4:45pm depicting a pendant shape in this small storm.

Rotating updraft of same cell ~2 miles to my NNW!

The same meso later on.

 

Poor contrast inflow stinger to meso

RFD occlusion led to demise of meso


 

Looking SW: neat LP convection and inflow along a strong outflow boundary in NW IL.

Final view of LP convection shortly before collapsing.

 

RFD gust front occluding new rotation to the north (left). Note shearing on top is to the north.

Same boundary feeding into rotating storm (directly over my previous location!).

Impressive rainfoot to the west.


 

View of last individual cells to the west before consolidation.

 

Racing north to Platteville shortly before being blasted by winds and hail.
