Based on 1800 UTC surface analysis and satellite imagery through 2345 UTC. ...TROPICAL WAVES... An Atlantic Ocean tropical wave is along 20W from 13N southward, moving west at about 10 kt. Precipitation: scattered moderate convection is from 05N to 09N between 18W and 22W. An Atlantic Ocean tropical wave axis is along 45W from 13N southward, moving westward 10 to 15 kt. NO convection is observed at this time with this feature. A Caribbean Sea tropical wave axis extends from 18N70W to 10N72W, moving westward 15 kt. Precipitation: no significant convective precipitation is apparent in satellite imagery due to Saharan dust in the wave's environment. A tropical wave extends over the Yucatan Peninsula along 91W, moving westward at 10 kt. Scattered moderate convection is observed south of 20N between 88W-94W. ...MONSOON TROUGH/ITCZ... The monsoon trough extends from 10N14W to 08N19W. The ITCZ is along 07N23W to 04N40W. Precipitation: Scattered showers are noted along the ITCZ between 22W-28W. ...DISCUSSION... GULF OF MEXICO... A stationary front extends from a 1009 mb Atlantic Ocean low pressure center that is near 33N76W, across northern Florida, continuing across the northernmost parts of the Gulf of Mexico, and beyond the Upper Texas Gulf coast. Precipitation: widely scattered moderate to isolated strong rainshowers cover the Gulf of Mexico from 25N northward between 80W and 91W, including across Florida. An upper level trough extends from the NE corner of the Gulf of Mexico into the Yucatan Peninsula. The current 90W tropical wave is moving across the Yucatan Peninsula also. No significant deep convective precipitation is apparent in satellite imagery. A stationary front across the NE Gulf from northern Florida to New Orleans will dissipate slowly through tonight. A surface trough will develop along the Yucatan Peninsula each afternoon, and then drift westward in the the SW Gulf at night. CARIBBEAN SEA... An upper level trough extends from the NE corner of the Gulf of Mexico into the Yucatan Peninsula. Broad upper level anticyclonic wind flow spans the rest of the Caribbean Sea, to the east of the trough. Precipitation: isolated moderate to locally strong rainshowers are from 15N northward from 74W westward, being on the eastern side of the trough. The monsoon trough is along 10N from NW Colombia westward, beyond NW Costa Rica. Precipitation: widely scattered moderate to isolated strong rainshowers are from 13N southward from 76W westward to Central America.

A stationary front extends from a 1009 mb Atlantic Ocean low pressure center that is near 33N76W, across northern Florida, continuing across the northernmost parts of the Gulf of Mexico, and beyond the Upper Texas Gulf coast. Precipitation: broken to overcast multilayered clouds and isolated moderate to locally strong rainshowers are to the north of the line that runs from 27N80W at the coast of Florida beyond 32N67W. Other isolated moderate to locally strong rainshowers are present from 25N northward between 60W and 74W. A surface ridge extends from a 1025 mb Atlantic Ocean high pressure center that is near 32N26W, to 27N40W, to a 1020 mb high pressure center that is near 24N54W, to 22N70W, and eventually toward NW Cuba. Precipitation: isolated moderate to locally strong rainshowers are from 20N to 28N between 70W and 80W, covering the Bahamas and parts of Cuba. Abundant moisture is streaming northeastward, on the eastern side of the NE Gulf of Mexico-to-Yucatan Peninsula upper level trough. A broad ridge across the west-central Atlantic Ocean will dominate the regional weather through Sunday. A stationary front will linger off northeast Florida through Thursday.
