SATELLITE ANALYSIS OF Gulf Of Mexico - Caribbean Sea image shows at 2330 Z MAR 23 2014 the following: FOUR North Atlantic (non tropical) Low Pressure Storm One North Atlantic Low Pressure System That Is Located At 30.00 N 95.00 W One North Atlantic Low Pressure System That Is Located At 30.00 N 90.00 W ... One North Atlantic Low Pressure System That Is Located At 35.00 N 81.00 W One North Atlantic Low Pressure System That Is Located At 35.00 N 75.00W ONE Tropical Waves One Tropical wave that is located at 31.00 N 75.00 W to 25.00 N 79.00 W GULF OF MEXICO... WESTERLY FLOW ALOFT IS NOTED ON WATER VAPOR IMAGERY OVER MUCH OF THE GULF BASIN THIS EVENING AS BROAD MIDDLE TO UPPER LEVEL RIDGING REMAINS ANCHORED OVER SOUTHERN MEXICO AND CENTRAL AMERICA NEAR 17N91W. WHILE FAIRLY ZONAL...GLOBAL MODEL GUIDANCE INDICATES VERY WEAK MID-LEVEL ENERGY FOCUSED OVER LOUISIANA NEAR 29N90W AND THE LARGER-SCALE TROUGHING TO THE NORTH OVER THE GREAT LAKES REGION THAT SUPPORTS A COLD FRONT EXTENDING FROM THE FLORIDA PANHANDLE NEAR 31N84W W-SW TO 29N90W TO THE SOUTHERN TEXAS GULF COAST NEAR 27N97W. MOSAIC DOPPLER RADAR IMAGERY AND LIGHTNING DATA INDICATE SCATTERED SHOWERS AND ISOLATED TSTMS OCCURRING ACROSS THE NORTHERN GULF GENERALLY N OF 27N... INCLUDING INLAND PORTIONS OF THE EASTERN TEXAS...LOUISIANA...AND SOUTHERN MISSISSIPPI AND ALABAMA. OTHERWISE...THE REMAINDER OF THE GULF IS UNDER INFLUENCE OF WEAK PRE-FRONTAL TROUGHING WHICH IS RESULTING IN AN OVERALL LIGHT AND VARIABLE WIND REGIME. A WEAK 1019 MB HIGH IS CENTERED ACROSS WESTERN CUBA AND IS EXPECTED TO CONTINUE DISSIPATING DURING THE NEXT 24 HOURS. LOOKING AHEAD...A STRONGER SECONDARY COLD FRONT IS EXPECTED EARLY TUESDAY ACROSS THE GULF AS CYCLOGENESIS OCCURS IN THE SW NORTH ATLC. THE LOW IS EXPECTED TO DEVELOP QUICKLY N-NE ALONG THE EASTERN U.S. SEABOARD WITH THE FRONT CLEARING THE GULF BASIN BY LATE TUESDAY INTO EARLY WEDNESDAY. STRONG N-NE WINDS IN THE RANGE OF 20 TO 25 KT WILL FOLLOW IN WAKE OF THE FRONT AS A STRONG PRESSURE GRADIENT SETS UP WEDNESDAY INTO THURSDAY. CARIBBEAN SEA... WEST TO NORTHWEST UPPER LEVEL WINDS PREVAIL OVER MUCH OF THE CARIBBEAN BASIN THIS EVENING WITH WATER VAPOR IMAGERY INDICATING VERY DRY AND STABLE AIR OVER THE REGION. THE OVERALL STABILITY AND LACK OF ANY SIGNIFICANT MOISTURE IS RESULTING IN MOSTLY CLEAR SKIES AND FAIR CONDITIONS. THE ONLY AREA OF POSSIBLE ISOLATED SHOWER ACTIVITY IS OCCURRING ALONG THE NICARAGUA... COSTA RICA...AND WESTERN PANAMA COAST DUE TO LOW-LEVEL MOISTURE CONVERGENCE. FINALLY...THE OTHER SIGNIFICANT IMPACT TO NOTE ACROSS THE BASIN IS STRONG TRADE WINDS OCCURRING ACROSS THE SOUTH-CENTRAL CARIBBEAN S OF 15N BETWEEN 67W-78W. THESE TRADES RANGE FROM 20 TO 25 KT AND ARE EXPECTED TO PERSIST THROUGH TUESDAY. ...HISPANIOLA... VERY DRY AND STABLE AIR ALOFT IS NOTED ON WATER VAPOR IMAGERY OVER HISPANIOLA THIS EVENING RESULTING IS MOSTLY CLEAR SKIES AND FAIR CONDITIONS. THIS OVERALL SYNOPTIC PATTERN IS EXPECTED TO PERSIST OVER THE NEXT FEW DAYS DUE TO PERSISTENT UPPER LEVEL NORTHWESTERLY WINDS.
