Description:
...ANOTHER PERIOD OF SNOW FOR THE CENTRAL AND NORTHERN PANHANDLE
SATURDAY...
.Widespread snowfall has begun across the coastal and northern
panhandle as of early Saturday morning as the first front pushes
into the coast. There are no major changes to current forecast
snow accumulations for Saturday. There is still some uncertainty
of exact snow accumulations at the surface for Saturday afternoon
as temperatures at sea level are expected reach into the mid 30s
to the upper 30s due to increasing daylight and sun angle while
in contrast, temperatures aloft are still favorable for
accumulating snow amounts. This battle between the warmer surface
temperatures and cooler atmosphere will be the main forecast
challenge through Saturday afternoon. If the heavier precipitation
rates are significant enough to overcome the warmer surface
temperatures, snow accumulations will be greater. But if the
temperatures are able to overcome the precipitation rates,
snowfall will be limited as it melts by the time it reaches the
surface. This will need to be monitored for any changes in
potential snow accumulation. The orientation of the low and where
the showers move into the panhandle will also impact the snow
amounts, with how northward and inland the heavier moisture will
push and how organized the bands of snow are expected to be when
moving through this weekend. Highest snow rates are expected to
continue through Saturday morning before warmer temperatures in
the afternoon begin to limit snow accumulations. Additional bands
of snow may move into SE AK through the remainder of the weekend.
* WHAT...Snow expected. Total snow accumulations of 3 to 5
inches. Winds gusting as high as 45 mph.

* WHEN...From 4 AM to 7 PM AKDT Saturday.
* IMPACTS...Travel by land, air, and sea could be impacted.
* ADDITIONAL DETAILS...Highest snow rates will be through Saturday
morning. Temperatures are expected to warm through the afternoon
into the mid 30s and may likely lead to lower snow totals.
