WEATHER Invest 96L // Yucatan Penisulia//FYI

An area of low pressure has been invested by the NHC/TPC as 96L. May move westward into the bay of Campeche where development is possible. Just FYI for the moment.

...DISCUSSION...

GULF OF MEXICO...
AN UPPER TROUGH OVER THE E CONUS AND A SECONDARY UPPER TROUGH
OVER MEXICO EXTEND INTO THE GULF. AS A RESULT...SOUTHWESTERLY
FLOW ALOFT COVERS MUCH OF THE GULF...WITH MOISTURE STREAMING
THROUGH THE FLOW OVER THE GULF SE OF A LINE FROM 27N85W TO
20N97W. ALSO TO THE SE OF THIS LINE...A SURFACE TROUGH EXTENDS
FROM 23N88W TO A 1012 MB SURFACE LOW OVER THE YUCATAN PENINSULA
NEAR 19N89W...AND ANOTHER SURFACE TROUGH EXTENDS FROM NEAR THE
FLORIDA KEYS NEAR 25N82W TO THE S FLORIDA PENINSULA NEAR 25N80W.
WEAKLY CONVERGENT FLOW INTO THESE FEATURES...COMBINED WITH
MOISTURE AND ATMOSPHERIC LIFT IN SW FLOW ALOFT...IS RESULTING IN
SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS OVER THE GULF S OF
26N BETWEEN 81W-88W. ISOLATED SHOWERS ARE OCCURRING OVER THE BAY
OF CAMPECHE IN RESPONSE TO LOW LEVEL SUPPORT FROM THE SURFACE
LOW OVER THE YUCATAN PENINSULA. DRY CONDITIONS COVER MUCH OF THE
GULF NW OF A LINE FROM 27N85W TO 20N97W.

CARIBBEAN SEA...
AN UPPER RIDGE EXTENDS FROM W CUBA TO THE GULF OF HONDURAS...
WITH DEEP MOISTURE CIRCULATING AROUND THE RIDGE. ALSO...A
1012 MB SURFACE LOW IS OVER THE YUCATAN PENINSULA NEAR
19N89W...WITH A SURFACE TROUGH EXTENDING FROM THE LOW INTO THE
GULF OF MEXICO NEAR 23N88W. THESE FEATURES CONTINUE TO RESULT IN
SCATTERED MODERATE CONVECTION OVER THE NW CARIBBEAN N OF 17N AND
W OF 82W...AFFECTING THE YUCATAN PENINSULA AND BELIZE. TO THE
E...AN UPPER TROUGH EXTENDS NORTHWARD FROM PANAMA TO HAITI. DEEP
TROPICAL MOISTURE AND WEAKLY UNSTABLE AIR WITHIN THE
TROUGH...COMBINED WITH WEAK LOW LEVEL CONVERGENCE NEAR THE ITCZ
AXIS...ARE RESULTING IN SCATTERED MODERATE CONVECTION FROM
9N-14N BETWEEN 72W-81W...AFFECTING THE SW CARIBBEAN. OVER THE E
CARIBBEAN...DRIER AIR IS PRESENT UNDER WEAK A WEAK RIDGE
ALOFT...WITH ISOLATED SHOWERS S OF 16N AND E OF 69W BEING
SUPPORTED BY THE ITCZ.

ATLANTIC OCEAN...
AN UPPER TROUGH OVER THE E CONUS CONTINUES TO SUPPORT MOIST
SOUTHWESTERLY FLOW ALOFT OVER THE SW ATLC...WHERE A WEAKENING
STATIONARY SURFACE FRONT EXTENDS FROM 23N71W TO 28N77W AND A
SURFACE TROUGH EXTENDS FROM 28N77W TO THE S FLORIDA PENINSULA
NEAR 25N80W. THE COMBINATION OF THESE FEATURES CONTINUES
RESULTING IN ISOLATED SHOWERS AND THUNDERSTORMS WITHIN 150 NM
EITHER SIDE OF THE WEAKENING STATIONARY SURFACE FRONT AND THE
SURFACE TROUGH. AN UPPER HIGH NEAR 29N68W AND ITS ASSOCIATED
UPPER RIDGE ARE BRINGING DRY AND STABLE CONDITIONS TO THE W ATLC
N OF 21N BETWEEN 59W-74W. A DEEP UPPER LOW SPINNING OVER THE
CENTRAL ATLC NEAR 22N57W IS SUPPORTING A SURFACE TROUGH THAT
EXTENDS FROM 27N55W TO NEAR 21N56W. THIS SURFACE TROUGH
CONTINUES TO MOVE WESTWARD ON THE SOUTHERN PERIPHERY OF THE
SURFACE RIDGE OVER THE CENTRAL ATLC ANCHORED BY A 1025 MB HIGH
NEAR 34N38W. THE SURFACE TROUGH IS SUPPORTING SCATTERED MODERATE
CONVECTION WITHIN 180 NM E OF THE TROUGH AXIS S OF 22N AND
ISOLATED MODERATE CONVECTION WITHIN 150 NM E OF THE TROUGH AXIS
N OF 25N. OVER THE NE ATLC...AN UPPER TROUGH IS N OF 19N BETWEEN
THE W AFRICAN COAST AND 32W. UPPER SUPPORT FROM AN UPPER LEVEL
WIND SPEED MAXIMUM E OF THE TROUGH AXIS IS GENERATING SCATTERED
MODERATE CONVECTION FROM 20N-24N BETWEEN 18W-23W. THE TYPICAL

GULF OF MEXICO...
AN UPPER TROUGH IS MOVING ACROSS THE NE US ONLY EXTENDS TO OVER
THE NE GULF COAST STATES WITH THE BROAD UPPER RIDGE ANCHORED IN
THE YUCATAN CHANNEL COVERING ALL OF THE GULF WATERS BRINGING
MOIST TROPICAL AIR ACROSS THE S AND E GULF S OF A LINE FROM NE
FLORIDA NEAR 30N83W TO MEXICO BETWEEN MATAMOROS AND TAMPICO. A
1008 MB LOW THAT HAS MOVED FROM THE CARIBBEAN ACROSS THE YUCATAN
PENINSULA NOW IS ALONG THE COAST OF THE BAY OF CAMPECHE NEAR
NEAR CIUDAD DEL CARMEN WITH A SURFACE TROUGH (96L) EXTENDING N INTO
THE GULF OF MEXICO NEAR 24N89W...THIS MAY BECOME A SPECIAL
FEATURE OVER THE NEXT FEW HOURS AS IT MOVES INTO THE BAY OF
CAMPECHE. HEAVY SHOWERS/THUNDERSTORMS ARE ASSOCIATED WITH THIS
FEATURE S OF 22N TO INLAND OVER MEXICO BETWEEN 89W-94W.
SCATTERED SHOWERS/ISOLATED THUNDERSTORMS ARE OVER THE E GULF
FROM 26N-29N E OF 86W ACROSS THE FLORIDA PENINSULA. A THIN LINE
OF SHOWERS ARE IN THE NW GULF FROM 26N92W TO 28N94W AS INDICATED
BY MOSAIC RADAR IMAGERY. ISOLATED SHOWERS ARE MOVING W IN THE
FLORIDA STRAITS. A SURFACE RIDGE IS BUILDING OVER THE NE GULF
WITH THE NEXT FRONTAL BOUNDARY EXPECTED TO ENTER THE GULF LATE
TUE.

CARIBBEAN SEA...
A BROAD UPPER RIDGE COVERS THE NW CARIBBEAN ANCHORED IN THE
YUCATAN CHANNEL AND EXTENDS N OVER THE GULF OF MEXICO. TO THE E
IS AN UPPER LOW CENTERED JUST OFF THE SW COAST OF JAMAICA
EXTENDING AN UPPER TROUGH SW TO CENTRAL NICARAGUA. THE REMAINDER
OF THE CARIBBEAN IS DOMINATED BY A BROAD UPPER RIDGE ANCHORED
OVER E VENEZUELA. MOIST OF TROPICAL AIR REMAINS ACROSS THE
ENTIRE CARIBBEAN. HOWEVER...CLUSTERS SCATTERED SHOWERS/ISOLATED
THUNDERSTORMS ARE INLAND AND WITHIN 120 NM ALONG THE COASTS OF
HISPANIOLA...CUBA...AND CENTRAL AMERICA LEAVING MOST OF THE
CENTRAL WATERS WITH ISOLATED SHOWERS AT MOST.

ATLANTIC OCEAN...
A LINGERING DISSIPATING STATIONARY FRONT ENTERS THE W ATLC NEAR
32N71W TO N OF THE BAHAMA ISLANDS NEAR 28N79W GENERATING
ISOLATED SHOWERS WITHIN 200 NM NW OF THE FRONTAL BOUNDARY. AN
UPPER RIDGE DOMINATES THE W ATLC ANCHORED NEAR 27N73W DRAWING
THE MOIST TROPICAL AIR ACROSS THE FLORIDA PENINSULA TO N OF THE
FRONTAL BOUNDARY AND SUPPORTING DRY STABLE AIR ACROSS THE
REMAINDER OF THE W ATLC N OF THE CARIBBEAN FROM 62W-76W. A LARGE
CUT-OFF UPPER LOW IS IN THE CENTRAL ATLC CENTERED NEAR 22N58W
WITH A SURFACE TROUGH EXTENDING FROM 27N55W TO 22N58W AND
GENERATING SCATTERED SHOWERS/ISOLATED THUNDERSTORMS WITHIN 75 NM
OF LINE FROM 20N52W 24N53W TO THE SURFACE TROUGH NEAR 26N57W AND
