Don't need to post every warning statement.

Not that big a deal at this point (not like we have a million warnings), but anything from precautionary/preparedness actions on down isn't really necessary.

a bunch of convention has developed SE of the north storm and it helped weaken it....lets see if any of these new storms will start to rotate

the south storm also has weakened and looks more linear...no active warnings but 6 TOR and 1 SVR so far

Still waiting on LOT and possibly IWX.  Last I saw they were still trying to pinpoint location(s) and the cwa boundary does run through that area.

If it crosses a CWA boundary, the begin time (or end time) recorded in that CWA is the time when it crosses said boundary.

But it didn't cross a cwa boundary? Video I shot was in IND cwa and IND issued public information statement. Should I bring this up with them or just let it be?

Survey Summary:

A small tornado touched down just north of West Galway Trail N in
a tree line behind some houses. The tornado uprooted and snapped
trees as it moved east. An eyewitness reported seeing a black mass
with debris moving horizontally. The tornado covered his house in
fallen trees. As it crossed Paper Mill Road, the inflow winds into
the tornado pulled off siding from nearby houses and moved light
objects several hundred feet. A camper parked on the southern edge
of the path rolled three times toward the center of circulation
and was destroyed. After crossing the road it struck an abandoned
farm house and did more tree damage. There was no more evidence of
damage after the tornado passed east of the farmhouse.

You can always submit your concerns via our office email account (link at the bottom of NWS IND's webpage). I wasn't there for this event, but the time on the PNS may have been estimated by radar.
