HURRICANE LESLIE DISCUSSION NUMBER  27
NWS NATIONAL HURRICANE CENTER MIAMI FL       AL122012
1100 PM AST WED SEP 05 2012

RECENT TRMM AND SSMI MICROWAVE IMAGES INDICATE THAT LESLIE HAS NOT
FORMED A CLOSED EYEWALL...AND IN FACT...THE INNER CORE CONVECTION
HAS BECOME SOMEWHAT RAGGED.  THERE IS STILL SOME INDICATION OF
WESTERLY SHEAR AS WELL...WITH MOST OF THE CONVECTIVE BANDING
LOCATED OVER THE EASTERN SEMICIRCLE.  THE INITIAL INTENSITY IS
BEING HELD AT 65 KT BASED ON DVORAK ESTIMATES OF T4.0 FROM TAFB AND
SAB...AND A UW-CIMSS ADT ESTIMATE OF T3.7/4.3.

BASED ON RECENT TRMM MICROWAVE FIXES...THE MOTION IS ESTIMATED TO BE
010/2 KT.  LESLIE SHOULD CONTINUE A SLOW NORTHWARD CREEP FOR THE
NEXT 48 HOURS OR SO WHILE IT REMAINS TRAPPED TO THE SOUTH OF A
MID-LEVEL HIGH CENTERED TO THE NORTHEAST OF BERMUDA.  THE HURRICANE
SHOULD GAIN SOME NORTHWARD MOMENTUM BY DAY 3 ONCE A DEEP-LAYER
TROUGH DEVELOPS OVER THE EASTERN UNITED STATES.  THE GFS MODEL HAS
SHIFTED BACK TO THE EAST ON THIS CYCLE AND IS THE EASTERNMOST AND
SLOWEST OF THE DYNAMICAL GUIDANCE ON DAYS 3 THROUGH 5.  SINCE THIS
HAS NOT YET TURNED INTO A CONSISTENT TREND...THE NHC FORECAST IS
BEING KEPT CLOSER TO THE MIDDLE OF THE GUIDANCE ENVELOPE AND IS
VERY SIMILAR TO THE PREVIOUS TRACK FORECAST.

LESLIE IS PRECARIOUSLY CLOSE TO DRY AIR LOCATED OVER THE WESTERN
ATLANTIC.  A CROSS SECTION BASED ON GFS MODEL DATA SHOWS AIR WITH
RELATIVE HUMIDITY LESS THAN 30 PERCENT ABUTTING AGAINST THE
CIRCULATION IN THE 250-500 MB LAYER.  SINCE MODERATE WESTERLY SHEAR
IS EXPECTED TO AFFECT LESLIE FOR THE NEXT 24 HOURS OR SO...THE DRY
AIR COULD CONTINUE TO SEEP INTO THE CIRCULATION.  IN ADDITION...
MICROWAVE DATA INDICATES THAT THE SEA SURFACE BENEATH LESLIE IS
COOLING DUE TO UPWELLING...AND THIS IS UNLIKELY TO CHANGE AS LONG
AS THE HURRICANE MOVES SO SLOWLY.  THE NHC INTENSITY FORECAST IS
MOSTLY UNCHANGED FROM THE PREVIOUS ONE AND INDICATES GRADUAL
STRENGTHENING DURING THE NEXT 3 TO 4 DAYS. 

LESLIE IS A LARGE TROPICAL CYCLONE THAT IS FORECAST TO GROW IN SIZE
OVER THE NEXT SEVERAL DAYS. THE WIND FIELD OF THE CYCLONE...
COMBINED WITH ITS EXPECTED SLOW MOTION...WILL HELP TO GENERATE
LONG-PERIOD SWELLS THAT WILL PRODUCE LARGE WAVES AND LIFE-
THREATENING RIP CURRENTS ON BERMUDA AND MUCH OF THE U.S. EAST COAST
FOR THE REMAINDER OF THIS WEEK.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CARIBOU ME
327 PM EDT WED SEP 5 2012......

.....LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/.....

........LOW PRESSURE WILL DRAW A COLD FRONT EASTWARD ACROSS THE REGION SATURDAY NIGHT THROUGH SUNDAY. AT THE SAME TIME...AN UPPER TROF WILL MOVE EAST TOWARD THE REGION THROUGH THE WEEKEND. THIS WILL RESULT IN A PERIOD OF RAIN AND SHOWERS FOR SATURDAY NIGHT INTO SUNDAY AS MOISTURE IS DRAWN NORTHWARD IN ADVANCE OF THE FRONT. WHAT SHOULD THEN BE HURRICANE LESLIE WILL ALSO BE TRACKING NORTH SUNDAY THROUGH MONDAY. CURRENT INDICATIONS ARE THAT THE COLD FRONT AND UPPER TROF CROSSING MAINE SHOULD STEER THE STORM EAST OF THE GULF OF MAINE TOWARD NOVA SCOTIA MONDAY. HOWEVER...MOISTURE BEING DRAWN NORTH FROM LESLIE INTO THE FRONTAL BOUNDARY COULD ENHANCE RAINFALL ACROSS THE REGION SUNDAY NIGHT INTO EARLY MONDAY DEPENDING ON THE LOCATION OF THE FRONT AND THE EXACT TRACK OF THE STORM. A PERIOD OF HIGH SURF CAN ALSO BE EXPECTED BY SUNDAY INTO MONDAY REGARDLESS OF THE TRACK AS LARGE WAVES WILL BE PROPAGATED WELL AWAY FROM THE STORM`S CENTER. FINALLY, A PERIOD OF GUSTY WINDS WILL ALSO BE POSSIBLE BY MONDAY DUE TO THE PRESSURE GRADIENT SETTING UP BETWEEN THE STORM TO THE EAST AND HIGH PRESSURE TO THE WEST. THE STORM WILL RAPIDLY LIFT NORTH THROUGH THE MARITIMES LATER MONDAY WITH DIMINISHING SHOWER CHANCES. HIGH PRESSURE SHOULD THEN BUILD EAST TUESDAY INTO WEDNESDAY........

Tropical cyclone information statement updated by the Canadian
Hurricane Centre of Environment Canada at 3:10 PM ADT Wednesday
5 September 2012.
---------------------------------------------------------------------
Tropical cyclone information statement for:
      Atlantic provinces.

      For hurricane Leslie.

      The next statement will be issued at 9:00 AM ADT Thursday.

      General discussion regarding recently-upgraded hurricane Leslie
      And possible influence in Eastern Canada.

---------------------------------------------------------------------
==discussion==
The Canadian Hurricane Centre is monitoring the development of
hurricane Leslie.  The storm is expected to move very slowly and
intensify gradually over the next 3 days.  Computer models are
predicting Leslie to only travel 250 kilometres over the next 2 days
which is basically a person's average speed of walking.  With such a
slow speed of travel and the fact that the storm is still in its
organizing stage, there is much (more than usual) uncertainty in the
predicted path and intensity.

Computer models indicate that Leslie should eventually push through
the large 'Bermuda high' and accelerate toward Eastern Canada with a
range of track scenarios spanning Nova Scotia and Newfoundland.
The middle of these track forecasts crosses through Newfoundland -
but even that 'average' will likely shift several times with each new
run of simulations.  If Leslie makes it to Eastern Canada, it would
not likely do so until early next week.  There are other factors such
as 'cold-water upwelling' and 'high pressure building' resulting from
the hurricane itself that the computer models can sometimes fail to
predict.  Thus, the range of scenarios may be even broader than those
models indicate now.

The Canadian Hurricane Centre will continue issuing these general
information statements on Thursday with more detailed track
information forecasts likely beginning on Friday.

August 2012: Warmest on Record for Caribou and 2nd Warmest for Houlton (Maine)


...August 2012: Warmest on Record for Caribou and 2nd Warmest for Houlton...

August 2012 will go down in the record books as the warmest August on record for Caribou (records began in 1939) and the 2nd warmest for Houlton (records began in 1948).

Caribou's average temperature was 68.0F, beating the old record of 67.2F from 1944. Houlton's average temperature was 67.7F, coming up just shy of the record of 67.9F from 1973.

Although temperatures were also several degrees warmer than average for Bangor and Downeast, they did not come close to record territory for the month as a whole.

What was interesting about August 2012 was that it wasn't super hot (Caribou only topped out at 89F and Houlton 88F), but it was consistently warm. For example, both Caribou and Houlton had the most 75F+ days on record in August with 25 and 27 days respectively, even though no one day hit 90F.

For the "meteorological summer" as a whole (Jun 1-Aug 31), it was the 3rd warmest on record for Caribou, 9th warmest for Houlton, but only 20th warmest for Bangor. And, like August, we didn't have many really hot days, but it was consistently warm. For example, Caribou tied its most 75F+ days for Jun 1-Aug 31 with 60.
