C3LOUD-Ex mobile platforms (primarily sounding vans and drone systems) followed an area of thunderstorms that became more intense as they moved to ranges of ~100 km from CHILL. By 2157 UTC a Bounded Weak Echo Region (BWER) reflectivity structure became apparent in the storm inflow / updraft area. Some of the project sondes intercepted these strong updrafts. During a time period when mobile platform support was not needed (2332 - 0046 UTC), the radar conducted rapid update, 4 sweep PPI sector scans that covered additional isolated storms that developed behind (i.e., at shorter radar ranges) the BWER echo system.
