Area Forecast Discussion National Weather Service Jackson MS 353 AM CST Mon Dec 9 2019
DISCUSSION. Through tonight: WV imagery this morning showing our next weather maker in the form of a mid level wave dropping south through southern CA into northwestern Mexico. In advance, a large swath of moisture has been tapped from west of Baja and is being funneled northeastward across the southern CONUS in increasingly southwest mid level flow. Already, mid/high level cloudiness has built into the region.
At the surface, high pressure remains centered off the east coast while a shallow cold front approaches the MS valley from the Plains. The tightening pressure gradient ahead of the boundary will allow low level winds to increase today, especially over the open areas of the ArkLaMiss Delta. As the southwest flow aloft continues and low level winds increase today, moisture levels will increase steadily in the column, enough so for showers to be possible by late morning/afternoon over the south and west.
Coverage of showers will increase from the northwest tonight as convergence along the frontal boundary encounters increasing low level moisture. Some thunder looks possible over the south where model soundings are indicating 300-500 J/kg of skinny CAPE ahead of the boundary. With the mid level energy moving into the region after midnight, backing winds aloft will allow widespread isentropic rains to break out, especially overtop the passing boundary./GG/
Tuesday Night through Sunday: Really the only period of interest for the remainder of the week will be Tuesday into Tuesday night as the anticipated shortwave trough swings east over our region and a colder post-frontal air mass seeps in from the northwest. With the right entrance region of the upper-level jet positioned overhead into Wednesday night, frontogenesis through the mid- levels should continue to support precipitation falling behind the cold front. Drier air will gradually work in aloft and at the surface as the trough axis moves eastward, but there may be enough of a window for a wintry mix to develop in the cooling air mass.
Looking at forecast soundings especially across northern Mississippi and southeast Arkansas, the column will be awfully close to the tipping point between all rain and all snow, with precipitation rates being increased due to dynamics aloft. Given the uncertainties of just how much of a warm layer will remain aloft, and if low-level temps can chill to near freezing, weather type has been set at a mix of rain or snow mixing into areas generally around the US Highway 82 corridor and northwards. Have also included a light accumulation of snow up to around one quarter of an inch in those areas, but warmer ground temperatures and the likelihood of standing puddles, etc. before any kind of transition can occur will probably limit much if any accumulation. Will also include a "Limited" threat area for winter weather to the Hazardous Weather Outlook text and graphics for this potential. For areas to the south of this zone, a little light wintry mix cannot be ruled out as precip tapers off Tuesday night, but confidence in a change over is much lower to include in the weather grids at this time.
The rest of the forecast is relatively low key, with a gradual warming trend ahead of the next shortwave trough passage over the weekend. A chance for showers will return to parts of the forecast area Friday into Saturday as this system passes, but at this time do not anticipate thunderstorms or winter weather to be of any concern for the weekend. /NF/
AVIATION. 06Z TAF discussion: Ceilings will become predominantly MVFR overnight as winds increase from the south at 10 to 15 knots and gusty by sunrise. These conditions will last for the majority of the forecast period, although ceilings may rise to MVFR after 10/00Z as showers begin increasing from the west./GG/

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
