Hello,

 

Low clouds from the Ross Sea will begin to pick up with the progression of the low. A slightly higher but thin cloud ceiling currently pushes in to Crary from the SW today from across the Transantarctic Mountains. Ridging associated with a strong high pressure system in the Southern Ocean will aid in transporting clouds and mist in from the Ross Sea as the clouds develop further.  

 

Sunday: CIR will get a brief chance to see its surroundings until fog develops in the afternoon. Skies will be partly cloudy to mostly cloudy due to a patchy mid-level ceiling above CIR pushing in from the SW and developing. It will be relatively short lived until another low ceiling below 1000ft moves in from the north. Winds will be light and variable.

 

Monday: A weak upper low pressure system develops on the shelf near CIR and move to the East. The ridging moves completely away from the Ross Ice Shelf, and the lower cloud decks will follow. Skies will be low-ceiling overcast in the morning, but clouds will scatter out in the afternoon as the system draw away. Visibility will be 2-4 miles in the morning, lifting to unrestricted in the afternoon. Winds will remain light and variable.

 

Tuesday: Another fog bank with low cloud ceilings is expected to materialize. Expect visibility to be 3-5 miles in the morning and drop to 1-3 miles by midday with overcast skies. Winds will be light and variable.

 

Thank you,
