The strong low remainded near the pole. A second cold front crossed SHEBA ship. This front was weaker than the front of July 26th. However, cloud cover was very dense. The radar reported echoes up to 9 km earlier in the day (21:00 UT). At 23:30 UT faint echoes up to 8.5 km were reported. Cloud bases varied from 1.5 to 2.5 km during the flight. From 23:20 to 23:35, the radar reported echoes down to near the surface. Light rain was reported in the ship's 00 UT weather observation. Visibilities remained high through out the day - 10 miles. The satellite images show a lot of horizontal variability in both the visible and IR giving the appearance of convective cells.
The trajectories to SHEBA ship show the air from all levels flowed around the low north of the ship. The 1.0, 1.5, and 3.0 km trajectories make a full circle indicating that this air originated near SHEBA ship about 5.5 days earlier. The surface trajectory only makes a half circle around the polar low going back to Europe. The high level trajectories circle around the low to Greenland.
