...DISCUSSION...

THE GULF OF MEXICO...
A MIDDLE LEVEL TO UPPER LEVEL TROUGH IS CHURNING SOUTHWARD 
THROUGH MEXICO...ALONG 100W. CYCLONIC FLOW THAT IS AROUND THE 
TROUGH COVERS THE AREA THAT IS TO THE NORTH OF 20N BETWEEN
90W AND 110W. STRONG SHOWERS AND THUNDERSTORMS THAT ARE WITHIN
15 NM ON EITHER SIDE OF 25N91W 27N89W ARE ASSOCIATED WITH
A SQUALL LINE. A SURFACE TROUGH HUGS THE TEXAS GULF COAST 
WATERS. A SEPARATE AREA OF CYCLONIC FLOW FROM 26N TO 31N BETWEEN 
THE WEST COAST OF FLORIDA AND 90W...IS CAUGHT UP IN THE LARGER 
AREA OF CYCLONIC FLOW THAT EMANATES FROM MEXICO. SHOWERS ARE 
FROM 26N TO 31N BETWEEN 81W IN FLORIDA TO 90W.

THE CARIBBEAN SEA...
A MIDDLE LEVEL TO UPPER LEVEL INVERTED TROUGH EXTENDS FROM 
12N61W IN THE SOUTHEASTERN CORNER OF THE AREA TO EASTERN 
VENEZUELA NEAR 6N63W. ISOLATED MODERATE SHOWERS COVER THE AREA 
FROM 9N TO 11N BETWEEN 59W AND 63W. SHOWERS ALSO ARE POSSIBLE
INLAND IN VENEZUELA TO THE EAST OF 65W. BROAD MIDDLE LEVEL TO 
UPPER LEVEL ANTICYCLONIC FLOW COVERS THE NORTHWESTERN CORNER OF 
THE AREA...TO THE NORTH OF 16N TO THE WEST OF 75W. THE CENTER
IS NEAR 16N85W JUST OFF THE COAST OF HONDURAS. BROAD AND
COMPARATIVELY LESS WELL-DEFINED UPPER LEVEL CYCLONIC FLOW COVERS
CENTRAL AMERICA AND THE SOUTHWESTERN CORNER OF THE AREA TO THE 
SOUTH OF THE ANTICYCLONIC FLOW TO THE WEST OF 75W. UPPER LEVEL 
ANTICYCLONIC FLOW COVERS THE AREA TO THE NORTH OF 16N TO THE 
EAST OF 75W ALSO. 

THE ATLANTIC OCEAN...
SCATTERED STRONG SHOWERS AND THUNDERSTORMS ARE FROM 21N TO 26N 
BETWEEN 67W AND 70W...ASSOCIATED WITH A SURFACE TROUGH THAT IS 
ALONG 24N70W 22N73W INTO THE WINDWARD PASSAGE. A CENTRAL 
ATLANTIC OCEAN MIDDLE LEVEL TO UPPER LEVEL TROUGH PASSES THROUGH 
33N47W TO 26N48W TO 17N49W. THIS TROUGH SUPPORTS IN SOME WAY THE 
SURFACE TROUGH THAT IS ALONG 31N27W TO 29N30W TO A 1020 MB LOW 
PRESSURE CENTER THAT IS NEAR 29N34W. THE TROUGH CURVES AWAY FROM
THE LOW CENTER TO 25N35W 25N42W 20N46W AND 16N50W. MULTILAYERED
CLOUDS AND POSSIBLE PRECIPITATION REMAIN FROM 23N TO 30N BETWEEN
40W AND 46W.
