Synopsis for the the SW N ATLC including the Bahamas .SYNOPSIS...A large pressure gradient between the Bermuda High and a strong cold front, for this time of year, over the eastern Gulf of Mexico is causing S winds up to gale force north of the NW Bahamas today. The front will reach the Atlantic waters tonight and S winds up to gale force will push farther east on Sat before diminishing below gale on Sun. Forcing behind front should produce substantially weaker W winds. The cold front should extend from 31N74W to the central Bahamas Sat afternoon, from 31N71W to the SE Bahamas Sun afternoon, and becoming stationary near the same location Mon afternoon, and finally dissipating on Tue. Numerous showers and scattered strong thunderstorms will accompany the front. There is potential for severe thunderstorms associated with the front north of 27N tonight and Sat.
