Nome really frowns on
risk-takers I guess. Some radiational cooling did occur but not nearly as much
as it often does with fresh snow cover, light winds, and mostly clear skies. The
wind then mysteriously got going way earlier than expected, limiting the low to
14F. So far, max wind is 15 kt. It is cloudy now and temperatures will continue
to rise through tomorrow with southerly winds off the Bering Sea, warm
advection, and thick cloud cover, so no radiational cooling is expected. The
warm advection and upslope will lead to enhanced precipitation in the form of freezing
rain and then rain, given the impressive warm surge aloft. Although the mountains
are to the north, the not-so-strong southerly winds and very stable lower
atmosphere will lead to the upslope flow being blocked, with a very low Froude
number, leading to the flow being forced upward before reaching the mountains
and over the coastal area, like Nome. This might be why the high-resolution
models show much higher precipitation (even like 1.5-2”), and while they are
probably exaggerated, they might have a point. The blocked flow and deep snow
cover will also prevent the temperatures from surging too much and the wind
from getting that strong. The MOS temperatures seem
way too high.
