Area Forecast Discussion National Weather Service Jackson MS 548 PM CDT Fri Sep 18 2020

UPDATE. Updated for 00Z aviation discussion

AVIATION. 00Z TAF discussion:

High level moisture streaming across the area will support some lowering of cloud decks, and even some --RA over the Pine Belt region, but ceilings will remain VFR across the entire area through the forecast period with breezy northeast surface winds continuing. /EC/

DISCUSSION. Tonight and tomorrow . High pressure is building into the region as the 500 mb pattern shifts to more northwesterly flow in the eastern half of the CONUS. Cirrus/mid level clouds stream into the region from TD 22 in the western Gulf of Mexico. General subsidence over the area through tonight and tomorrow will keep the forecast dry for the most part with the exception of some isolated showers creeping into the south tomorrow afternoon. Overnight lows will drop into the lower 60s and upper 50s with the drier air in place over the southeast. Tomorrow's highs remain below seasonal normals . in the lower 80s and upper 70s.

Sunday - end next week (Sunday- next Friday) . Sunday-next Tuesday . The region will be under building mid-level ridge across the Ozarks & Mid-South while likely developing Tropical Storm Beta(?) across the western Gulf of Mexico. With the strengthening mid- level ridge axis & surface high building across our region, this will keep the tropical activity suppressed well to our southwest across the western Gulf of Mexico near the Texas coastline. The tropical system is progged to slowly move west- northwest before beginning the northeast drift along the coastline. Southwesterly flow aloft could help some higher & dense cirrus to drift across the area. Slightly below normal highs are expected Sunday, while increasing cloud cover & some better moisture will help some rain chances/clouds & cooler than normal highs at the start of the work week (i.e. Monday-Tuesday). Kept rain chances slightly suppressed to mostly slight chances due to a slow uptick in moisture & no real low-level convergence mechanism.

Wednesday-Friday: As the mid-level & surface high ridge axis build east-southeast into the southeastern CONUS & eastern Gulf of Mexico, the tropical system will slowly drift northeast along the Texas coastline into mid-late week. This will help a warm front to lift northeast into the area & in conjunction with better deeper moisture near 2 inch PWs, help better rain chances move in mid-late week (i.e. Wednesday & especially Thursday). There is some spatial differences in the global consensus, with the GFS slower to phase & Euro showing faster closed low/progged northeast ejection of the tropical system. At the most, expect increasing rain chances across our southwestern half of the ArkLaMiss mid-week on Wednesday & better consensus of scattered rain & storm coverage across our southern half of the region Thursday. With some synoptic uncertainties, left highest scattered coverage across southwest Wednesday & southern half Thursday. Some rain chances could linger into end of the work week on Friday, but synoptic details are unclear at the moment. With considerable uncertainty on progged track & intensity, there remains lower than normal confidence in eventual downstream impacts. Otherwise, expect below normal but slight uptick in warmth closer to normals by mid-late week. /DC/

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.
