Scattered thunderstorms formed along a boundary that sliced from eastern to southern portions of Indiana during the early afternoon hours on the 23rd.  By the late afternoon and early evening, an elevated front dropped south into central Indiana which allowed for an increase in moisture across the northern half of the warning area. Scattered thunderstorms developed along this boundary and produced large hail and some damaging wind across northern portions of the Indianapolis metro area.

Thunderstorm Wind in HAMILTON, INDIANA
From 23-MAR-11 19:05:00 to 23-MAR-11 19:05:00 (EST-5)
Location: NOBLESVILLE
Magnitude: 70.00 EG
Property damage: 60.00K
Crop damage: 0.00K
Reported by: NWS Storm Survey

Based on a National Weather Service damage survey, it appeared the wind damage in Noblesville during the evening of Wednesday March 23 was caused by downbursting straight line winds.  The majority of the damage was uprooted pine trees and downed Bradford Pear trees and limbs, both of which tend to be damaged by winds of 60 to 80 mph. The trees were laid down in an outward fanning or diverging pattern often found with a downburst wind event.  Most trees west of State Road 37 were blown down by a strong south wind.  Trees and fences east of State Road 37 were blown down by strong west-southwest winds.   This damage occurred at the lead edge of the storm, not the usual location at the rear of the storm where a tornado typically would form.  Other damage included stripped shingles and siding from around a dozen homes.
