Area Forecast Discussion
National Weather Service Jackson MS
925 PM CDT Sat Jun 2 2018

.UPDATE...
Updated for evening discussion.

&&

.DISCUSSION...
Updated the forecast to reflect the current trends. Storms to the
west continue to pound that area but weren't quite making much
southward progress. Storms just ahead of the boundary were a
little further away, so slowed the rain moving into the area. It
looks like another hot and muggy night with mid to upper 70s
likely. Could see one or two record low max records broken at
Hattiesburg, Jackson or Meridian. Other than the timing of the
rain, no really changes to the forecast./07/

&&

.AVIATION...
00Z TAF discussion:
VFR flight categories will continue to prevail at all TAF sites
into this evening. A complex of showers and storms are progged to
rapidly drop south southeast into and through the area late this
evening and during the overnight hours. Convection during this
time will cause both ceilings and visibilities to drop to MVFR/IFR
categories for at least a 1-4 hour period of time. Gusty northwest
winds are expected with this complex, along with frequent
lightning, and heavy downpours. Both ceilings and visibilities
will quickly improve in the wake of this convection. Winds will
subside to light from the west around 3-5 knots ahead of the
complex. /17/19/
