Area Forecast Discussion National Weather Service Jackson MS 400 PM CST Tue Dec 10 2019

DISCUSSION. Tonight through Wednesday: The cold front has now cleared the area, with strong cold advection continuing along with a considerable swath of post-frontal precipitation. Light snow began mixing in with the rain north of the US 82 corridor around midday. For the most part, precipitation has been rather light, and given the warm ground temperatures and air temperatures still hovering above freezing, this has prevented any notable accumulations thus far. More recently, precipitation has begun to change to all snow across parts of SE Arkansas over into the Cleveland area, where there is now a light dusting of snow in grassy areas.

Though precip has been generally light so far, an approaching shortwave and a right upper jet entrance region are enhancing precip over NW Louisiana. This area of somewhat greater precip rates will likely move across northern portions of the CWA during the evening hours, presenting a brief window of potential for some light snow accumulations. From an impacts perspective, bridges and elevated surfaces have the greatest potential to cool off enough for slick spots to develop, and we'll continue to highlight this as the main concern. Accumulations of around 1/2" are possible, but I wouldn't be entirely surprised if a locally higher total is reported. Farther south, precipitation is expected to end before there is a meaningful window of opportunity for impacts, but a brief mix of light rain and snow is possible north of I-20 before precip ends.

Clouds will clear quickly behind the precip late tonight into Wednesday morning, with mostly sunny and cool (albeit warmer than today) conditions on Wednesday. /DL/

Wednesday night through Monday night . Surface high pressure ridging will prevail across the region Wednesday night, with lows falling into the low to mid 30s for most of the area. As the surface ridge continues to shift east of the area on Thursday, moisture will begin to increase across the south with a chance for light rainshowers. An upper short wave will move into the region Thursday evening and a surface low will deep over the northern gulf moving into the Florida Panhandle on Friday. Light rainshowers will spread northward over much of the area Thursday night on the backside of the this low and continue into Friday. As the upper trough axis swings across the area Friday evening into the overnight hours, the showers will end from west to east. The GFS is the outlier during this period, indicating that most of the precip will remain east of the area. Will lean towards the ECWMF because it lines up better with the NAM/GEM solutions.

Weak high pressure ridging will build in for Saturday and continue through Sunday. A nice weekend is on tap with highs mostly in the 60s to low 70s. The global models are in general agreement that a deep upper trough and associated strong cold front will sweep across the area on Monday and Monday night. Depending on the movement of the track of the surface low, it looks like there will be some potential of severe weather early next week. Considering this is still a week away, will hold off on any mention in the HWO/Graphicasts. /15/

AVIATION. 18Z TAF discussion: Central Mississippi TAF sites alternating this morning between MVFR and IFR conditions. Low cigs and a lot of visibility variability dominate the short term. Deep rich moisture streaming into the region in southwesterly flow aloft will keep the area primed for precip through tonight. Concern for a quick changeover to snow this evening for northern terminals.

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.
