THE WEATHER PATTERN ACROSS SOUTHEAST ALASKA WILL TURN VERY COLD AND WINDY STARTING LATE FRIDAY NIGHT AND PERSIST THROUGH NEXT WEEK. A STRONG HIGH PRESSURE CENTER WILL BUILD OVER THE YUKON FRIDAY NIGHT AND THE NORTHERN PANHANDLE SATURDAY. THIS HIGH PRESSURE WILL SEND VERY COLD ARCTIC AIR ACROSS THE AREA CAUSING TEMPERATURES TO FALL THROUGH THE DAY FRIDAY INTO THE 20S OVER THE NORTHERN AREAS AND LOWER 30S OVER THE SOUTHERN AREA. TEMPERATURES WILL CONTINUE TO FALL THROUGH THE WEEKEND WITH HIGHS RANGING FROM THE SINGLE DIGITS OVER THE NORTHERN THIRD OF THE PANHANDLE TO THE MID 20S TO MID TEENS OVER THE SOUTHERN THIRD. LOW TEMPERATURES WILL RANGE FROM BELOW ZERO OVER THE NORTHERN HALF TO LOW TEENS OVER THE SOUTH THIRD. THE COLD AIR WILL PERSIST INTO NEXT WEEK AND HIGH TEMPERATURES WILL RANGE FROM SINGLE DIGITS OVER THE NORTHERN HALF AND NEAR 20 OVER THE SOUTHERN HALF. LOWS WILL REMAIN BELOW ZERO TO SINGLE DIGITS. PEOPLE SHOULD TAKE ACTION TO KEEP PIPES FROM FREEZING SINCE MANY LOCATIONS ACROSS SOUTHEAST ALASKA ARE SNOW FREE.
ALONG WITH THE VERY COLD TEMPERATURES THE HIGH PRESSURE WILL PRODUCE VERY STRONG WINDS FROM THE NORTHEAST. WINDS WILL INCREASE THROUGH FRIDAY NIGHT AND PERSIST INTO NEXT WEEK. MARINE WATERS WILL SEE WIDESPREAD GALES OVER THE NORTHERN TWO THIRDS WITH GUSTS FROM 60 TO 70 KT OUT OF INTERIOR PASSES OVER THE INNER CHANNELS AND OVER THE NORTHEAST GULF. THE STRONG WINDS AND COLD TEMPERATURES WILL PRODUCE HEAVY FREEZING SPRAY LATE FRIDAY NIGHT INTO SATURDAY AND CONTINUE THROUGH THE WEEKEND. THERE WILL ALSO BE VERY STRONG WIND GUSTS IN EXPOSED AREAS AND NEAR INTERIOR PASSES OVER LAND AREAS. THE JUNEAU AREA CAN EXPECT TAKU WINDS TO DEVELOP LATE FRIDAY NIGHT AND PERSIST INTO EARLY NEXT WEEK. THE COMBINATION OF THE STRONG WINDS AND COLD TEMPERATURES WILL CREATE VERY COLD WIND CHILLS RANGING FROM -30 OVER THE FAR NORTHERN AREAS TO -10 OVER THE CENTRAL INNER CHANNELS.
