Conditions over the Atlantic region to the east of KCOF expanded to become a large area of stratiform precipitation from JAX down toward MIA. Moisture was fed from numerous convective cells throughout the day, but by early evening the area toward JAX southward to Daytona beach began an impressive disintegration as subsidence took over in the northern regions of the precip. Low level winds in the area (sfc-700mb) were largely convergent, with the axis of convergence just about over KCOF. Weak and temporary linear features were seen in the radar imagery, but they were short lived. Orientation of the lines were generally east/west, but they built and collapsed so rapidly that at times it seemed that the orientation was north/south. Elsewhere, the depression turned into TS Bonnie by mid afternoon located about 17.9N 60.7W at 21Z.
Accomplished spirals and multi-level penetrations of convective cells offshore from Melbourne, about 80-90 km ENE of S-POL. Thanks to the radar tech at S-POL who supported the mission with volume scans. The target was a cluster of rather strong (for ocean) cells on the NW flank of a mesoscale convective band. The band propagated northward by such growth. Very interesting variety of particles sampled; instruments appeared to work well. Takeoff 2248 UT/21 Aug; landing 0031 UT/22 August.

Convective cell sampling with S-Pol only. S-Pol was doing sector scans in the area We did a stair-step climb between 10 k feet and 29 k feet in a moderate rain cell east of the radar. Had a few strong updrafts. Selected a second cell and did a down. Results should provide vertical profiles through two convective cells. There's a cirrus shield (anvil) that topped the cells.
