Area Forecast Discussion...UPDATED
National Weather Service Jackson MS
940 PM CDT SUN SEP 25 2016

.DISCUSSION...Convection continues for the western half of the cwa.
Raised pops to scattered this evening and maintained a slight chance
in the west overnight. Models were in decent agreement with activity
expected to continue through the night and redevelop along the
prefontral trough axis by late tonight/early Monday morning...mainly
for the western zones. Not sure how far the actual front will make it
tonight. The tail end of the boundary seems to extend down into
northwest Arkansas at time, but models show it moving a little slower
through the CWA. Considered raising temps along the MS river the low
at GLH was 75 last night. However winds were out of the northeast and
there were breaks in the clouds, so some slightly drier may move
settle in and help with cooling. Basically tweaked the pops and
adjusted the hourly values to line up with current trends. Also added
patchy fog to the southeast. Otherwise, the forecast was ok. The
update was already out.

.AVIATION...An axis of scattered SHRA/TSRA mainly west of the
GLH/JAN/HBG corridor is lingering well into the evening in the
summerlike airmass. Expect the convective threat to diminish
overnight with loss of daytime heat and VFR conditions should
prevail. There may be some fog/stratus development during the early
morning hours, particularly in rain areas. Stratus may be a bigger
concern in the GLH to GWO area Monday morning in association with a
weak cold frontal passage, but confidence is low in this scenario.
Expect additional SHRA/TSRA development Monday aftn ahead of the cold
front. /EC/
