...A WARMER AND DRIER AUGUST FOR ST PAUL ALASKA...

AUGUST 2015 WAS A CONTINUATION OF WARMER TRENDS FOR ST PAUL. HIGH PRESSURE EARLY IN
THE MOTH KEPT THINGS RELATIVELY DRY. LOWS ON THE 7TH AND 13TH BROUGHT PERIODS OF
LIGHT SHOWERS THROUGH THE AREA. ANOTHER HIGH BUILT BACK OVER THE EASTERN BERING
BEFORE BEING ERODED AWAY BY THE 27TH...AND THE TRAILING FRONT BEHIND A LATE MONTH
LOW MOVING NORTH THROUGH ST.LAWRENCE ISLAND SPARKED VIGOROUS SHOWERS...INCLUDING
PERIODS OF HEAVY RAIN WHICH INCLUDED 0.15 INCHES OF RAINFALL IN ONLY 15 MINUTES AT
TIMES. IT WAS NOT ENOUGH TO MAKE UP FOR WHAT ENDED UP BEING A 0.64 INCH DEFICIT FOR
THE MONTH.

WITH RESPECT TO TEMPERATURES...THE AVERAGE DAILY MAXIMUM TEMPERATURE WAS THE FIFTH
WARMEST...THE AVERAGE DAILY MINIMUM TEMPERATURE WAS THE FIFTH WARMEST ON
RECORD...AND THE AVERAGE MEAN DAILY TEMPERATURE CAME IN FOURTH WARMEST ON RECORD.
FIVE HIGH MINIMUM TEMPERATURE RECORDS WERE SET OR TIED AS FOLLOWS:

8/17 50 TIED THE RECORD SET IN 2005.
8/25 51 BROKE THE RECORD OF 50 SET IN 2004.
8/26 51 BROKE THE RECORD OF 50 SET IN 2004.
8/27 49 TIED THE RECORD SET IN 1996.
8/28 50 BROKE THE RECORD OF 49 SET IN 2005.

AUGUST 2015 WAS BELOW NORMAL FOR PRECIPITATION. THE MONTHLY PRECIPITATION TOTAL
RANKED 21ST DRIEST ON RECORD. HOWEVER...A PRECIPITATION RECORD OF 1.32 INCHES WAS
SET ON THE 29TH...WHICH SUPPLANTED THE 0.83 INCHES SET IN 2006.
