TROPICAL STORM TOMAS DISCUSSION NUMBER 1
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL212010
500 PM AST FRI OCT 29 2010

AN AIR FORCE RESERVE RECONNAISSANCE AIRCRAFT INVESTIGATING THE
VIGOROUS TROPICAL WAVE LOCATED SOUTHEAST OF THE WINDWARD ISLANDS
FOUND A CLOSED SURFACE CIRCULATION...ALONG WITH FLIGHT-LEVEL WINDS
AND UNCONTAMINATED SFMR SURFACE WINDS THAT SUPPORT A 35-KT TROPICAL
STORM. AS A RESULT...ADVISORIES HAVE BEEN INITIATED ON TROPICAL
STORM TOMAS...THE NINETEENTH NAMED STORM OF THE 2010 SEASON.

THE INITIAL MOTION IS AN UNCERTAIN 295/15...DUE TO THE POSSIBILITY
OF REFORMATION OF THE LOW-LEVEL CENTER WITHIN THE CENTRAL DEEP
CONVECTION. TOMAS IS EXPECTED TO CONTINUE MOVING WEST-NORTHWESTWARD
FOR THE NEXT 48 HOURS...PASSING THROUGH THE WINDWARD ISLANDS IN
ABOUT 24 HOURS OR SO. AFTER THAT...THE BROAD TROUGH THAT IS LOCATED
OFF THE U.S. EAST COAST AND THE BAHAMAS IS FORECAST TO LIFT OUT TO
THE NORTHEAST...WHICH ALLOWS A RIDGE TO BUILD TO THE NORTH OF TOMAS
ACROSS THE GREATER ANTILLES...THE BAHAMAS...AND FLORIDA. THE
EASTERLY FLOW ON THE SOUTH SIDE OF THE RIDGE SHOULD FORCE TOMAS ON
MORE OF A WESTERLY TRACK THROUGH 96 HOURS. BY DAY 5...A SECOND MUCH
DEEPER TROUGH IS EXPECTED TO DIG SOUTHWARD INTO THE SOUTHERN PLAINS
AND SOUTHEASTERN U.S. AND CAUSE THE RIDGE AND ASSOCIATED STEERING
CURRENTS TO WEAKEN. THE RESULT SHOULD BE A SHARP DECREASE IN
FORWARD SPEED BY 120 HOURS. THE NHC MODEL GUIDANCE IS IN GOOD
AGREEMENT ON THIS DEVELOPING SCENARIO...EXCEPT FOR THE GFDL AND
HWRF MODELS...WHICH ARE CONSIDERED TO BE OUTLIERS AT THIS TIME.
THE OFFICIAL FORECAST TRACK IS ALONG THE SOUTHERN EDGE OF THE
GUIDANCE ENVELOPE...BUT NOT AS FAR SOUTH AND WEST AS THE GFS...
ECMWF...AND UKMET MODELS...WHICH ARE DEPICTING A MUCH WEAKER AND
SMALLER TROPICAL CYCLONE THAN IS EXPECTED.

RECON AND SATELLITE DATA INDICATE THE LOW-LEVEL AND UPPER-LEVEL
CIRCULATIONS ARE NOT YET VERTICALLY ALIGNED...WHICH SHOULD RESULT
IN ONLY SLOW INTENSIFICATION IN THE NEAR TERM. HOWEVER...WITH A
CENTRAL PRESSURE OF 998 MB...VERY MOIST MID-LEVELS...AND LOW
VERTICAL SHEAR...IT WOULD NOT TAKE MUCH FOR TOMAS TO INTENSIFY AT A
FASTER THAN NORMAL RATE. WHILE NOT EXPLICITLY INDICATING RAPID
INTENSIFICATION...THE OFFICIAL INTENSITY FORECAST REFLECTS THESE
FAVORABLE ENVIRONMENTAL CONDITIONS...AND IS ABOVE THE SHIPS/LGEM
INTENSITY MODEL GUIDANCE.

CHANGES WITH THIS ADVISORY...

NONE.

Tomas is not messing around. Looks like a CDO is forming.

If Tomas traverses the northern half of the Caribbean, I would not be surprised if he becomes the strongest November hurricane on record.

18Z...

What will Tomas do if and once he enters the Gulf of Mexico?

DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
AT 1100 AM AST...1500 UTC...THE CENTER OF HURRICANE TOMAS WAS
LOCATED NEAR LATITUDE 13.3 NORTH...LONGITUDE 60.7 WEST. TOMAS IS

HURRICANE TOMAS DISCUSSION NUMBER 6
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL212010
500 PM AST SAT OCT 30 2010

AN AIR FORCE RESERVE HURRICANE HUNTER AIRCRAFT INVESTIGATING TOMAS
THIS AFTERNOON FOUND MAXIMUM 700 MB FLIGHT-LEVEL WINDS OF 67 KT IN
THE NORTH QUADRANT...WHICH EQUATES TO ABOUT 60 KT SURFACE WINDS.
SATELLITE INTENSITY ESTIMATES ARE A CONSENSUS T4.0/65 KT FROM TAFB
AND SAB. THE STRUCTURE OF TOMAS HAS IMPROVED CONSIDERABLY IN RADAR
IMAGERY FROM MARTINIQUE...AND THE CYCLONE NOW POSSESSES A CLOSED 25
N MI DIAMETER EYE. THE INTENSITY IS BEING HELD AT 65 KT FOR THIS
ADVISORY...WHICH COULD BE A LITTLE LOW BASED ON SOME OF THE DAMAGE
REPORTS THAT HAVE BEEN RECEIVED FROM HAM RADIO OPERATORS ON ST.
LUCIA AND ST. VINCENT.

THE INITIAL MOTION ESTIMATE IS 290/09. TOMAS REMAINS ON TRACK...
AND THERE IS NO SIGNIFICANT CHANGE TO THE PREVIOUS FORECAST TRACK OR
REASONING. THE LOW- TO MID-LEVEL RIDGE TO THE NORTH OF TOMAS IS
EXPECTED TO CONTINUE TO BUILD WESTWARD ACROSS THE GREATER ANTILLES
FOR THE NEXT 96 HOURS...WHICH SHOULD KEEP TOMAS ON A WEST-NORTHWEST
TO WESTWARD TRACK. HOWEVER...A BROAD LONGWAVE TROUGH CURRENTLY
ALONG THE U.S. WEST COAST IS EXPECTED TO MOVE EASTWARD AND THEN
SOUTHEASTWARD INTO THE SOUTHEASTERN UNITED STATES...AND PINCH OFF A
CLOSED LOW OVER THE GULF OF MEXICO AND SOUTHEASTERN MEXICO BY 120
HOURS. THE STRONG SOUTHWESTERLY FLOW ON THE EAST SIDE OF THE
AFOREMENTIONED TROUGH AND LOW IS EXPECTED TO RESULT IN A
SIGNIFICANT EROSION OF THE WESTERN PORTION OF THE GREATER ANTILLES
RIDGE AND CAUSE THE STEERING CURRENTS ACROSS THE WESTERN AND
CENTRAL CARIBBEAN SEA TO WEAKEN...ALLOWING TOMAS TO SLOW DOWN
CONSIDERABLY AND BEGIN TO MOVE POLEWARD. MOST OF THE MODEL GUIDANCE
IS IN GOOD AGREEMENT ON THIS GENERAL TRACK SCENARIO EXCEPT FOR
SPEED DIFFERENCES. THE OFFICIAL FORECAST TRACK IS JUST AN UPDATE OF
THE PREVIOUS ADVISORY TRACK...AND REMAINS ALONG THE SOUTHERN EDGE
OF THE NHC GUIDANCE ENVELOPE...BUT NOT AS FAR SOUTH AS THE GFS AND
ECMWF MODELS.

WITH A CLOSED EYE AND A FAVORABLE UPPER-LEVEL ENVIRONMENT...TOMAS IS
FORECAST TO STRENGTHEN FOR THE NEXT 24 HOURS OR SO BEFORE WEAK
WESTERLY 400-300 MB WINDS UNDERCUT THE IMPRESSIVE OUTFLOW LAYER AND
ENTRAINMENT OF DRY MID-LEVEL AIR FROM THE WEST COMBINE TO INTERRUPT
THE STRENGTHENING PROCESS. HOWEVER...BY 48-72 HOURS...ENVIRONMENTAL
CONDITIONS ARE FORECAST TO IMPROVE...WHICH SHOULD ALLOW TOMAS TO
RESUME STEADY INTENSIFICATION. THE GFS-BASED SHIPS AND LGEM MODELS
ARE FORECASTING STEADY WEAKENING AFTER 48 HOURS...BUT THAT IS
BELIEVED TO BE DUE TO ERRONEOUS MODEL-INDUCED SOUTHWESTERLY
VERTICAL SHEAR AFFECTING TOMAS AS A RESULT OF THE OFFICIAL FORECAST
TRACK BEING ABOUT 120 N MI NORTH OF THE LARGE SCALE UPPER-LEVEL
ANTICYCLONE DEPICTED IN THE GFS MODEL. THE INTENSITY FORECAST
REMAINS ABOVE THE SHIPS/LGEM MODELS...AND IS SIMILAR TO THE
PREVIOUS FORECAST AND LAST TWO GFDL MODEL RUNS.
