Area Forecast Discussion...UPDATED National Weather Service Jackson MS 912 PM CDT Sun Sep 4 2022 .UPDATE... Updated for evening discussion. && .DISCUSSION... A few showers and thunderstorms will continue to be possible overnight, mainly focused over eastern parts of Mississippi, where moisture content is greater (PWAT ~2.2 inches). Zooming out to the CONUS scale, water vapor satellite imagery clearly shows the deep upper-level trough which extends from the Great Lakes southwest toward Texas and the broad plume of moisture being lifted northeast ahead of it. Several embedded low pressure centers can be seen rotating in the axis of the trough, including a disturbance of particular interest centered over OK/AR and its cold front diving into TX at this hour. In addition to the general flow of warm moist air over our region, increasing 850mb flow on the east side of this disturbance will support the chance for showers and thunderstorms capable of producing heavy rain through the day tomorrow. POPs were adjusted based on latest trends in guidance, but overall thinking remains the same from previous forecast. Flow aloft should carry any showers and storms to the northeast. Lastly, it should be noted that there is a chance for some fog development by early Monday morning, with best chances focused around the ArkLaMiss Delta region where skies have a chance to clear out some and temps could cool below afternoon crossover temps. /NF/ Prior discussion below: Tonight and Monday: Upper troughing will remain in control through the short term period as a broad weakness overhead will be slow to move, remaining to the west of the subtropical ridge centered over the western Atlantic. Our area will be on the eastern side of the upper trough where the height gradient will reach a relative maximum as the subtropical ridge becomes a bit stronger. This will allow a continued influx of moisture through the column as enhanced deep layer southwesterlies remain in place through Monday and beyond. At the surface, a weak frontal boundary reinforced by showers and storms will remain stalled northwest of our area which will serve to help focus confluence and moisture flux to its east and south further aiding in numerous showers and storms. With this moisture, we will see rain chances both tonight and Monday with some embedded thunderstorms. Storms may strengthen sufficiently during the afternoon and early evening hours Monday to allow for frequent lightning, gusty winds, and locally heavy rainfall. The risk for damaging wind will remain low due to a lack of available instability with cloud cover impeding effective diurnal warming. With showers and storms moving slowly, we could see some chance for isolated urban, poor drainage flooding with potential for ponding on roadways. After dropping into seasonable lows tonight in the lower 70s F, cloud cover and rain chances will result in afternoon temperatures below average for Monday with temperature similar to what we are seeing this afternoon in the middle 80s F. /86/ Monday night through Wednesday night: An elongated trough extending from the ArkLaTex to the Ohio Valley/Great Lakes region will continue to transport considerable deep layer moisture into the forecast area. While the larger scale pattern should not feature significant ascent for getting much rainfall, there could be subtle disturbances and occasionally favorable jet dynamics that might help to enhance the chances for convective rainfall, possibly resulting in localized heavy rainfall. Thursday through Saturday: Global models agree that the based of the upper level trough will cut off and and form a closes low near the lower MS Valley region that may persist for a few days. If this should be the case, then there could be greater moisture transport into portions of the forecast area resulting in greater coverage of convective rainfall, and perhaps greater potential for localized heavy rainfall. This will be pattern to monitor for and will hold off on any mention of heavy rainfall/flooding in the HWO graphics for now. /EC/ && .AVIATION... 00Z TAF discussion: A few SHRA and TSRA are still affecting parts of the forecast area to begin the TAF period, but coverage should continue to decrease with only a slight chance for showers or storms before 18Z Monday. Low stratus and patchy fog are expected to produce widespread MVFR to IFR conditions by 09Z to 12Z Monday, with conditions gradually improving to prevailing VFR between 14Z to 18Z. /NF/ && .PRELIMINARY POINT TEMPS/POPS...
