Area forecast discussion, Aug 2, 2:59 PM CDT, 2 hours 5 minutes before
Area Forecast Discussion National Weather Service Jackson MS 259 PM CDT Fri Aug 2 2019 .DISCUSSION... Tonight and tomorrow... For today, most of the activity has stayed east of I-55 and things have been minimal to the west. Thunderstorm chances will continue to stick around late this afternoon, but diminish with the loss of heating. Overnight, storms will have dissipated, but lingering cloud cover will help keep minTs in the lower 70s. A mid-level low, over the northern Gulf of Mexico, will push north tonight into AL. As this system continues to push through, thunderstorm chances will increase for the region tomorrow. PWs were showing some 1.84" in forecast soundings showing there will be some deep level moisture in place. While better lapse rates will exist in proximity to the cold core low, deep moisture will keep rates no greater than moist adiabatic. Despite the extensive cloud cover, low level convergence will be sufficient to initiate convection with some breaks in the cloud cover serving to initiate further development later in the day. Some storms may be strong with gusty winds but as of now, confidence isn't great for any severe chances. /JNE/26/ Next week: Somewhat higher than average summertime daily thunderstorm chances will remain through the end of the forecast period. An upper ridge will persist over the western/central CONUS, with troughing in the northeast to Atlantic coast. Through the week, the ridge will build slightly eastward, resulting in an uptick in temperatures in our area. Still, upper flow will remain northwesterly with a steady diet of weak upper disturbances traversing the Atlantic coast trough and tapping into a lingering rich supply of moisture across the region. Somewhat higher rain chances will exist on Sunday as a weak surface trough moves across the area. Lesser coverage is expected Monday into Tuesday as deep layer moisture decreases in the wake of this feature. However, a resurgence of moisture is anticipated Wednesday ahead of an approaching jet streak and shortwave, with somewhat greater rain chances continuing through next Friday. With upper heights increasing toward the end of next week, temperatures will trend slightly upward, with resultant heat indices potentially nearing the triple digits in some areas. /DL/ && .AVIATION... 18Z TAF discussion: Chances for some isolated to scattered thunderstorms will continue for some sites today mainly east of I-55. Other than that, VFR conditions will prevail. Some patchy fog is possible tomorrow morning just before sunrise so some sites may drop to MVFR for a short moment, but conditions will improve as we began to mix out after sunrise./JNE/ && .PRELIMINARY POINT TEMPS/POPS...
