...RECORD DRY WEATHER ACROSS SOUTHEAST ALASKA THIS OCTOBER...

CONSISTENT HIGH PRESSURE OVER WESTERN CANADA COMBINED WITH A MEAN
JET STREAM LOCATION TO THE SOUTH RESULTED IN VERY FEW LOWS AND THEIR
ASSOCIATED FRONTS FROM AFFECTING SOUTHEAST ALASKA THIS PAST OCTOBER.

OVERALL, MOSTLY CLEAR SKIES DOMINATED THE WEATHER FOR THE FIRST TWO
WEEKS OF THE MONTH. IN SPITE OF THE LOW SUN ANGLE, SOME RECORD WARM
HIGHS WERE RECORDED. THE CLEAR NIGHTS ALSO RESULTED IN SOME RECORD
COLD OVERNIGHT LOWS. MONTHLY AVERAGE TEMPERATURES TRENDED FROM
SLIGHTLY ABOVE, TO SLIGHTLY BELOW NORMAL.

RECORD, OR NEAR RECORD LOW PRECIPITATION TOTALS ACROSS THE PANHANDLE
WERE ALL THE MORE NOTABLE SINCE OCTOBER IS TYPICALLY ONE OF THE
WETTEST MONTHS OF THE YEAR FOR SOUTHEAST ALASKA. ANOTHER HIGHLY
ANOMALOUS WEATHER EVENT OCCURRED AROUND THE MIDDLE OF THE MONTH WHEN
8 TO 12 INCHES OF SNOW FELL OVER THE CENTRAL INNER CHANNELS. EVEN
THOUGH THE MONTH RECORDED RECORD LOW TOTAL PRECIPITATION, THE 5.1
INCHES RECORDED AT THE JUNEAU AIRPORT ON THE 16TH RESULTED IN THE
THIRD SNOWIEST OCTOBER ON RECORD.
