Atlantic high pressure extends a ridge across central Florida and then westward along 26N to S Texas. This ridge will shift E-NE through Wed, allowing a cold front to enter the NW Gulf Wed. Ahead of the front, fresh to locally strong southerly return flow will prevail over the western Gulf today, then expand into eastern portions Tue night into Wed. The cold front will sink into the northern Gulf Wed night into Thu, then stall from near Tampa Bay to the mouth of the Rio Grande Thu night, before lifting N Fri. ...CARIBBEAN SEA...

Precipitation: isolated to widely scattered moderate is within 135 nm on either side of the stationary front. Broad surface anticyclonic wind flow is on either side of the stationary front. A surface ridge extends from a 37N59W 1030 mb high pressure center, through 31N69W, to south Florida. Broad surface anticyclonic wind flow is to the east of the stationary front. A 1038 mb high pressure center is near 40N23W. Near gale-force NE winds are from 27N northward between the Canary Islands and 24W. Strong NE winds are from 20N to 27N from 25W eastward. Strong NE winds are: from 22N to 26N between 32W and 38W; from the stationary front to 28N between the front and 65W; and from 19N to 21N between 72W and 75W including in the Windward Passage.
