Glad to finally have a storm chase in my own
"backyard". I had laid down for a nap in the
afternoon and when I woke, found that severe storms
had erupted just to my north.
went into intercept mode. I decided to attack
the storm from the east. Headed north on 367 and
then west on Highway 94 when I got to West
Alton. I stopped briefly at the Sioux Energy
Power Plant just east of Portage De Sioux, Missouri to
take a closer look at radar. I was getting concerned
about hail size as the core of the lead storm was
about to cross in front of me.
a quick look, I determined I could continue west as
the lead storm was weakening slightly and figured
potential large, window-breaking hail would no longer
be an issue. As I moved west, then south on the curve on Highway
94, I was treated to many cloud to ground lightning
bolts. Unfortunately, the only pictures were
with the dash cam through the front windshield with
raindrops hitting the glass.
Once I got to I-370,
I made the decision to not follow the storm
southeastward into the urban areas, so I headed home
and made it just before the storms reached the house.

My son Ryan
was out in his own vehicle. He was
approaching the southern end of the storms from
the west. Here is his summary.....
I saw a
messy supercell develop to my north, so I headed out
for an intercept. I first stopped near an
updraft along New Town Boulevard in St. Charles
County Missouri where I noticed some minor rotation
under a wall cloud.
continued west on Highway "B" to intercept
another updraft. Knowing the area well, I
found a nice spot offering me a great view of my
surroundings. I was sitting about a
quarter mile south of the Hayford Road and the
Highway "B" intersection (about a mile or so
south of the Golden Eagle Ferry). A
massive scud cloud was pulled up to the bottom
of the storm and a wall cloud came into
view. Then a circulation formed under
it. It was very difficult to tell exactly
what both the cloud motion and ground motion
were like as contrast was a bit difficult, but
it appeared it was rotating. There was a
lot of rising and sinking motion going on as
well. It was extremely turbulent.
The first picture below was the first picture I
took of the feature and it is blurry
unfortunately. But what looks like a
funnel is present above the dust. The next
3 photos below show the dust under what appeared
to be rotation. The dust went away for a
few minutes, but then reappeared again just
before it got wrapped up in rain. I then
got hit by 60mph winds and had to bail.
I followed the storm south to
Mason Road and the I-40 intersection.
The wall cloud came into view with a rear
flank downdraft present.
this fell apart, the storm features become
hidden due to the wrapping rain and the
storm was heading into a more difficult
chase area, so I called it a day and headed
