Synopsis For Pascagoula MS To Okaloosa Walton County Line FL Out 60 NM Including Major Area Bays And Sounds - GMZ600
402 PM CST Wed Feb 19 2020

A light to moderate northerly wind flow will continue through early Thursday in the wake of a weak cold front that moved across the marine area earlier in the week. Northerly winds and seas will build late Thursday through early Friday in response to a stronger cold front that moves across the region by Thursday afternoon. A light to moderate east to southeast flow will develop over the weekend as a broad surface ridge of high pressure to north settles along the eastern seaboard.

NEAR TERM UPDATE /Now Through Thursday night/...Widespread light to moderate rain, generally located along and north of highway 84 this afternoon, will continue to fill in from the west overnight through Thu morning spreading southward over remaining areas of the forecast area generally before sunrise Thu, continuing through mid to late afternoon. This ongoing precipitation to the north is mostly from weak forcing occurring in the mid levels associated with a continued series of weak impulses tracking eastward in mostly a zonal flow across the deep south combined with deep moisture in the boundary layer (PWATs (Precipitable Waters) up to about 1.5 inches or slightly less) currently located generally over the northern half of the forecast area. This pattern remains fairly consistent with the better precipitation remaining well to the north this evening and most of tonight before shifting southward towards the coast and offshore later in the morning on Thu continuing through late afternoon and early evening in response to a well defined shortwave trough digging southward stretching from the central Plains States to the Mississippi River Valley and further east during the day on Thu. Near the surface a well defined cold front is also forecast to move south over the north central Gulf coast region by Thu afternoon with a few hours of light rain or drizzle in the wake of the front continuing through Thu evening. Due to very limited instability near the surface combined with the weak forcing aloft along with very weak lapse rates in the boundary layer the threat for thunderstorm development remains low to nil. The main concern will be the possibility of more nuisance type flooding or ponding of water where drainage is poor along with gusty northerly winds developing in the wake of the cold front late Thu afternoon and Thu night. For Thu night skies clear quickly generally from west to east with a brisk northerly flow at the surface making conditions feel more like winter for the deep south.

Temperatures will continue to be above seasonal norms for most locations tonight returning to near seasonal levels during the day on Thu then 4 to 6 degrees below seasonal norms for Thu night and early Fri morning. Lows tonight will range from the middle 40s to middle 50s generally from west to east inland and the middle to upper 50s closer to the coast. Highs Thu will range from the lower 50s to lower 60s generally from west to east for most inland areas and the middle 60s closer to the coast. Lows Thu night will fall to the lower to middle 30s generally north of the I-10 corridor and the upper 30s to lower 40s closer to the coast. 32/ee
