Commentary:
Many strong thunderstorms were observed visually and by radar to the
southeast last night, advecting toward the ship but dissipating as they
approached. The Ron Brown has remained within 200 m of the buoy all day
due to a cooperating wind. The Cessna overflights continue, twice per
day. Last night at sunset, the fishermen made a big catch.

Visual Observations:
Steady wind has roughened the sea surface. Many puffy marine boundary
layer cumuli, with occasional showers are developing around the ship.
Instrument Status:
The C-band radar is repaired and running well again. The column water
vapor discrepancy between sondes and the microwave radiometer (MWR) has
been resolved by adjustments to MWR processing parameters.
