Good day,

 

The ridge of the Ross Sea/ Southern Ocean high pressure system is pushed northwards by the developing low pressure system moving through the Bellingshausen Sea. As the low progresses further towards the Antarctic Peninsula, the outer pressure gradient across the Ross Ice Shelf may cause some lower cloud decks to be pushed over station later in the forecast period.

 

Monday: The skies today should remain mostly clear. Visibility will be unrestricted with possible drops to 2-4 due to increased winds and blowing snow overnight. Winds will be mostly S-SE at 8-12 knots, increasing to 13-18 knots gusting 25 in the evening.

 

Tuesday: The day will begin with clear skies until the low pressure system over Eastern Antarctica pushes clouds from the East to over CIR. Skies should be broken with a ceiling around 1000ft. Fog will begin to form around noon and continue into the evening, decreasing the visibility to 1-3 miles. Winds will be S-SE at 10-15 knots in the morning, declining to 5-10 knots from the SE in the evening.

 

Wednesday: The low overcast layer is expected to persist, and fog will likely be restricting visibility throughout the day to around 2-4 miles. Winds will be SE at 5-10 knots for most of the day.

 

Thank you,
