SYNOPSIS FOR THE SW N ATLC INCLUDING THE BAHAMAS .SYNOPSIS...Strong high pres centered over the central Atlantic will shift eastward through Mon in response to a cold front that extends from 31N77W to the NW Bahamas and to western Cuba this morning. The cold front will reach from near 31N75W to the central Bahamas and to central Cuba this evening, then become stationary from 31N73W to the central Bahamas and to eastern Cuba on Sun. A post-frontal trough will quickly swing across the NW waters and help to move the cold front a little farther to the SE from near 31N65W to the Windward Passage by Mon evening before it undergoes a weakening trend thereafter through Wed. A strong cold front will move off the SE United States coast on Wed and reach from near 31N74W to near 26N75W and to E central Cuba Wed night. Strong NW winds will follow in behind this front.
