SYNOPSIS FOR THE SW N ATLC INCLUDING THE BAHAMAS

.SYNOPSIS...The western segment of a stationary front that
extends westward from 27N65W to 27N75W and northwest to Cape
Canaveral Florida will lift northward as a warm front through

the forecast waters north of the Bahamas this afternoon and

eastward across the southeastern United States through tonight.
The surface low will track northeastward towards the Carolinas

front will move over the far northwest portion Wed night and Thu
before it also slows down Thu night and Fri.
