Greetings,

 

A weak high pressure system on the western side of the Ross Ice Shelf decays as it is pushed northwards past Ross Island over the next day and a half. A decaying low pressure system crosses into the Ross Sea and Ice Shelf from the Southern Ocean along the edge of the Western Antarctic side of the shelf.

 

Monday: Low overcast ceilings will be constant throughout the day. Visibility will be between ½ -2 miles in fog with visibility occasionally decreasing below ½ mile. Winds will be mostly light and variable, increasing in the evening to 5-10 knots from the SE.

 

Tuesday: Low overcast ceilings will be the condition for the morning into the afternoon. In the evening, the winds will begin to increase enough to thin out the fog on the shelf and improve visibility. Visibility will be ½ -3 miles due to fog in the morning, increasing to 4-6 miles in the afternoon. Winds will be SE at 5-10 knots in the morning, climbing up to 10-15 gusting 25 knots in the afternoon.

 

Wednesday: The low pressure system will continue to raise winds across the Ross Ice Shelf, though the exterior winds will be relatively weak. Visibility will be unrestricted in the morning and decline to ½-3 miles due to fog in the afternoon. Skies will be partly cloudy becoming overcast with low ceiling heights in the afternoon. Winds will be SSE at 10-15 gusting 25 knots in the morning, declining to SE at 5-10 knots in the late afternoon.

 

Thank you,
