Area forecast discussion...updated National Weather Service Jackson MS 958 PM CDT Tuesday Sep 2 2014 Update... strongest convection with the afternoon mesoscale convective system is mostly moving out of the region. Left probability of precipitation in until 06z for central/southeast MS. Left some slight chance wording in the NE due to a disturbance moving through and hrrr/RUC indicating some storms between 06-12z. However...this could be tough to do in the wake of the afternoon mesoscale convective system. Left some slight chance thunder into central MS due to some waning instability aloft. Storms should move out of southeast MS by 06z. Clouds will be slow to clear...mainly in the E/se...but could clear some from northwest to southeast. Due to the heavy rainfall in the region....higher boundary layer moisture...light winds and some clearing...put patchy fog in the grids for the entire area tonight after 09z Wednesday. Fog should lift around 15z Wednesday. Hrrr/GFS indicate some potential overnight for fog. Some areas could be locally dense where winds are lightest and clearing is the best. Lows look good overnight. Adjusted hourly temperatures/dewpoints to current trends. Rest of the forecast is on track. /DC/ && Aviation...light rain and a few embedded thunderstorms will end over southeastern portions of the region before midnight with only slight chances of precipitation in glh/gwo/cbm/gtr corridor through the rest of the night and into tomorrow morning. Many areas received a good deal of precipitation late today and at least partial clearing late tonight will set the stage for patchy fog formation by dawn Wednesday. MVFR flight cats in the 10 through 14 UTC should be relatively widespread with patchy and brief IFR conditions definitely possible. After 14z some minor MVFR ceilings could still be possible in the middle to late morning before conditions break to primarily VFR through the remainder of the day. However...expect more scattered thunderstorms and rain tomorrow afternoon which will bring a few issues for flight operations. /Bb/ && Previous discussion... /issued 739 PM CDT Tuesday Sep 2 2014/ Update...a localized organized thunderstorm cluster (small mcs) got going late this afternoon across central MS...and is now slowly weakening while pushing southeast to the I-59 corridor. Instability has waned to the point where severe weather is not looking likely although pockets of heavy rainfall remain possible over southeastern portions of MS over the next 1 to 2 hours. Further back over central MS the trailing stratiform region of the thunderstorm cluster will continue to produce generally light rain with an occasional rumble of thunder for the next few hours before dissipating altogether. Another update will come in a few hours to address fog potential for late tonight given surplus of wet ground across the region. /Bb/ Previous discussion... /issued 438 PM CDT Tuesday Sep 2 2014/ Discussion... Tonight through Wednesday night... Better moisture convergence supported initial development of shower and thunderstorm activity over north central into northeast MS earlier this afternoon...but it is now most prevalent over portions of northeast Louisiana extending northeastward into north central MS. Looking at storm total precipitation...there has been a relative min in activity along the I-20 corridor from Rayville to the Vicksburg area up until now... but with several nearby convective clusters...this will likely not remain the case as we go through the late afternoon into the early evening. Storm intensity has been strong at times with lapse rates marginal for supporting a few severe storms. Expect lesser but continued chances for shower/thunderstorms along the Highway 84 and I-59 corridors. Convection should diminish with sunset and have kept small probability of precipitation going in the forecast for late tonight across portions of north central MS with some nwp guidance still supporting it. The subtropical ridge axis will persist and become slightly more fixed over the lower MS valley region Wednesday through Wednesday night. Models generally agree that diurnal shower and thunderstorm activity will be focused along and southeast of the Natchez trace corridor and that coverage will be less than today due to less influence from the westerlies. A similar hot and humid airmass will persist with thermodynamic profiles supportive of a few strong to severe thunderstorms...and very moist air with precipitable water above two inches supports will support locally heavy rainfall. The activity will diminish quickly with sunset. /Ec/ Thursday through Monday... Deep layered ridge looks to remain anchored over the lower Continental U.S. Through the period. This should keep the moist and unstable airmass locked in place and a continuation of the sensible weather we have been experiencing. Will pretty much have to contend with afternoon/evening airmass convection each day through the extended time frame. Although convective coverage should remain scattered...storms may be somewhat more numerous over the south where interactions with the sea breeze may be encountered. Went close to GFS MOS maximums with highs in the low to middle 90s as believe this level of warming will still be likely given middle afternoon convective initiation times. Moving into the weekend...subtle middle level troffiness over the eastern portions of the country will allow a weak cold front to ease into the region from the north Saturday night/Sunday. The boundary looks as though it will quickly stall over the north and not offer anymore than an increase in convective coverage for the remainder of the weekend and the first part of next week. While the cool air behind the boundary should stay to the north of the area...increased convection Sunday and Monday should only allow maximums to reach around 90...but overnight lows will remain in the lower 70s./26/ && Preliminary point temps/pops...
