WITH THE SYSTEM ALREADY BEGINNING TO IMPACT SOUTHEAST ALASKA FRIDAY
MORNING WITH SNOW IN THE YAKUTAT AREA AND RAIN AROUND SITKA.

TEMPERATURES ACROSS MUCH OF THE PANHANDLE FRIDAY MORNING ARE RANGING
FROM THE LOW 30S TO THE UPPER 30S. ESSENTIALLY IT IS THE DEW POINT
TEMPERATURES THAT IS DETERMINING WHETHER THE PRECIPITATION TYPE IS
SNOW OR RAIN. ALTHOUGH THE BETTER CHANCES OF SNOW WILL BE OVER
NORTHERN LYNN CANAL REGIONS.

BELIEVE THAT MOST OF THE SNOW AMOUNTS WILL REMAIN UNDER THE
ADVISORY LEVELS THROUGH A FEW OF THE AREAS THAT WILL STAY SNOW

OUR TYPICALLY WINDY LOCATIONS ALONG THE OUTER COASTAL LOCATIONS

SNOW MIXED IN TOO. ADDITIONAL ACCUMULATIONS WILL RANGE FROM 2-4
INCHES SAT MORNING THROUGH SAT NIGHT FROM PETERSBURG NORTH.

BEHIND THE FRONT SCATTERED SNOW SHOWERS WILL CONTINUE OVER THE

TREND FROM NORTH TO SOUTH AS FLOW TURNS OFFSHORE. WINDS WILL SHIFT
FROM SOUTHEAST AHEAD OF THE FRONT TO SOUTHWEST BEHIND IT THEN
TURN OUT OF THE NORTH AS THE LOW MOVES TO THE SOUTHEAST. THE NORTH
