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/

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/
