Area Forecast Discussion . UPDATED National Weather Service Mobile AL 1122 AM CDT Mon Mar 30 2020

UPDATE. A Wind Advisory is now in effect for lower parts of southwest and south central AL . lower parts of inland southeast MS and all locations in the western FL Panhandle on Tue from 9 AM CDT through 7 PM CDT. Southwest to westerly winds at 15 to 25 mph with frequent gusts to 30 mph can be expected during this time frame. Gusty winds could blow around unsecured objects. 32/ee

PREV DISCUSSION. /issued 638 AM CDT Mon Mar 30 2020/

AVIATION . 12Z issuance . Clouds were streaming from west to east over the central Gulf coast. Bases today are expected to be at mid to high levels. Vsby ok. Light northeast winds this morning. Wind changes more from the east to southeast along the coastal portions mid-day into the afternoon. /10

PREV DISCUSSION . /issued 450 AM CDT Mon Mar 30 2020/

NEAR TERM UPDATE /Now Through Tuesday/ . 30.06Z Surface analysis shows a front draped just off the central Gulf coast with a cooler and drier air-mass in place. Unfortunately, this "less humid" weather will not last as the front begins to ease slowly northward as a warm, front today. Aloft, a flat ridge centered over the central Gulf supports a zonal west to east flow atop the area today with rain-free conditions. The next rain maker comes late tonight into Tuesday. A mid-level impulse in the southern stream over the central plains today ejects eastward tonight, approaching the Mid-South by daybreak Tuesday. Concentrated height falls allows for surface pressures to lower causing a frontal wave of surface low pressure to become better defined as it tracks east across central MS and AL Tuesday morning. In advance of the mid-level impulse, surface front and low, an increasingly diffluent flow operating on deeper Gulf moisture and increased layer ascent from the passage of a 120 to 130 kt speed max at high levels just to our north leads to increased coverage of showers and storms as the evolving warm sector undergoes destabilization. 0-6 km bulk shear magnitudes increase to 50 to 70 knots and with the passage of a modest H85 jet streak from 35 to 45 knots, the stage is set for strong to severe storms perhaps beginning as early as near daybreak Tuesday over interior southeast MS before spreading east through the remainder of the morning. Forecast soundings show veering low levels beneath strengthening westerly flow with height, supportive of organized storm updrafts, including supercells. In addition to damaging straight line wind gusts with the stronger storms, a tornado risk could develop as well. The Storm Prediction Center has outlooked the local area Tuesday for a slight risk of severe storms over portions of interior southeast MS eastward to the interior of southwest/southcentral AL. A marginal risk is outlooked over the Gulf coastal counties. The severe weather threat looks to taper off early afternoon over the eastern zones with any lingering convection there before moving out as the low moves quickly east over GA and SC.

Highs mostly in the lower to mid 80s today. Lows Monday night will be warm in the presence of increasing moisture ranging from near 70 at the coast to lower to mid 60s inland. Highs Tuesday in the upper 70s to lower 80s. /10/03

SHORT TERM /Tuesday night Through Wednesday night/ . An upper trof over the eastern states moves off into the western Atlantic through Wednesday morning and will be followed by an upper ridge which builds from the Plains into the eastern states through Wednesday night. A surface low associated with the upper trof will be located near coastal South Carolina early Tuesday evening with a trailing cold front which extends back westward to across the marine portion of the forecast area. As the front moves well off into the Gulf, much drier and cooler air flows into the region and remains in place during the remainder of the period as a surface ridge builds into the eastern states. Have continued with a dry forecast through Wednesday night. Lows Tuesday night range from the mid 40s well inland to the lower 50s at the coast and lows Wednesday night will be similar. Highs on Wednesday range from the upper 60s well inland to the lower 70s elsewhere. A moderate risk of rip currents is expected Tuesday night through Wednesday then a low risk follows for Wednesday night. /29

EXTENDED TERM /Thursday Through Sunday/ . Ridging both at surface and aloft prevails on Thursday, maintaining the dry and relatively mild conditions. By Thursday night, the ridging slides off to the east of the forecast area, allowing slight moisture return from off of the Gulf of Mexico to begin. Nearly zonal flow aloft Friday and Saturday, bringing a series of weak upper level disturbances east across the area. The combination of the increasing low level moisture and the weak impulses aloft will support isolated to low- end chances for showers Friday and Saturday, perhaps even lasting into Sunday. Models are hinting however at renewed ridging aloft on Sunday, and this may limit rain chances somewhat then, but a little too early to tell for sure. A slight warming trend returns Thursday through the weekend, but not nearly as extreme as it was prior to Tuesday's cold front thanks to persistent cloud cover, scattered showers, and a lack of strong upper ridging and associated deep- layer subsidence. High temps reach the upper 70s to lower 80s (over the interior) each afternoon and lows dipping into the upper 50s inland to low 60s each night, with the warmer temps along the coast. /12

MARINE . Main impacts to commercial and recreational boating interests comes Tuesday. A moderate to strong southwest to westerly flow and building seas to develop on Tuesday ahead of an approaching low pressure system and associated cold front. Winds, waves and seas locally higher in and near storms Tuesday. A moderate to strong offshore flow sets up Tuesday night in the wake of the frontal passage with seas continuing to build. Small craft advisories are in effect for southern Mobile Bay, adjacent MS Sound waters and over the open Gulf waters Tuesday through Mid-morning Wednesday morning. /10

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
