Early evening convection has developed across Central and
Northcentral Indiana, mainly associated with a couple notable
boundaries. All boundaries are found easily from the satellite
imagery, with a weaker less potent boundary displaced to the
southeast of the Indy Metro. The other is along the northern suburbs
of the Indy Metro, then the more active boundary along the northern
periphery of the forecast area from Warren/Fountain counties
stretching east through Tippecanoe into Carroll county. This
boundary is slowly drifting north, but along and just north there is
considerable upscale growth to the convective elements.
Unfortunately the boundary is equally adding some enhance helicity
and allowing a few updrafts to demonstrate some rotation based off
of latest radar imagery.

The environmental features are demonstrating around MUCAPE of
1000J/Kg within that northern boundary, further south MUCAPE is
marginally less but still worth a mention. Along the northern half
of the forecast area a layer of stronger wind shear is also found
within the 0-6km layer roughly in the 35-45kt range. This would
suggest that the continued development or sustaining the
current/ongoing convection will occur. But as convection lifts north
towards White County the environment is more favorable which is
along the stronger gradient of dynamics in the lowest 3km of the
atmosphere. Lapse rates are the one element keeping the atmosphere
under some control around 6-6.5 deg C/km which should help to limit
some stronger development and coverage for convection this evening
across Central Indiana.
