It's gettin nasty here: ATLANTIC... MID/UPPER LOW OVER THE FLORIDA STRAITS NEAR 25N79W IS THE MAIN FOCUS OF WEATHER TODAY. THE UPPER LEVEL TROUGH EXTENDS S INTO THE CARIBBEAN AND ALSO COVERS A PORTION OF THE E GULF. A SURFACE TROUGH...PREVIOUSLY A PORTION OF A TROPICAL WAVE...EXTENDS FROM 30N78W ALONG 26N79W TO CENTRAL CUBA NEAR 22N78W. DIFFLUENCE E OF THE UPPER TROUGH IS GENERATING A LARGE AREA OF CLOUDINESS WITH SCATTERED SHOWERS/ISOLATED THUNDERSTORMS S OF 32N TO OVER THE E CUBA AND HISPANIOLA AND A SMALLER AREA OF SCATTERED MODERATE/ STRONG CONVECTION FROM 22N-26W BETWEEN 70W-75W. A SWATH OF SCATTERED MODERATE/ISOLATED STRONG CONVECTION IS W OF THE WAVE WITHIN 45 NM OF LINE FROM 30N78W TO OVER THE E COAST OF FLORIDA BETWEEN VERO AND WEST PALM BEACH. THE UPPER TROUGH IS EXPECTED TO MOVE W INTO THE GULF OVER THE NEXT DAY OR TWO HOWEVER THE SURFACE FEATURE IS EXPECTED TO LAG BEHIND. A SURFACE LOW IS ALSO EXPECTED TO DEVELOP BY THE END OF THE WEEKEND. TROPICAL FORMATION IS NOT FAVORABLE AT THIS TIME BUT THE AREA HAS THE POTENTIAL FOR HEAVY RAINS AND GUSTY WINDS FOR CUBA...THE BAHAMA ISLANDS...AND THE E COAST OF FLORIDA. FARTHER E...AN AMPLIFIED MID/UPPER RIDGE EXTENDS FROM ACROSS PUERTO RICO NE TO BEYOND 32N57W. MODERATE/STRONG SUBSIDENCE IS BETWEEN THE THIS RIDGE AND A DEEP-LAYERED CENTRAL ATLC TROUGH THAT EXTENDS FROM BEYOND 32N46W S THROUGH AN UPPER LOW NEAR 29N47W TO 14N51W. A SURFACE TROUGH EXTENDS INTO THE AREA THROUGH 32N46W TO 25N54W. SCATTERED MODERATE CONVECTION IS WITHIN 250 NM SE OF THE SURFACE TROUGH FROM 25N-29N. SCATTERED SHOWERS/ISOLATED THUNDERSTORMS ARE WITHIN 75 NM OF 30W FROM 26N-32N. TO THE SE...BROAD MID/UPPER LEVEL RIDGE COVERS THE THE REMAINDER OF THE ATLC S OF 25N WITH A MID/UPPER HIGH LOCATED SE OF THE CAPE VERDE ISLANDS NEAR 14N30W. A SECOND UPPER LEVEL LOW IS OVER THE NE ATLC NEAR 29N27W. A SURFACE RIDGE EXTENDS THROUGH 32N34W SW TO 22N45W. |
