.DISCUSSION...
Issued at 102 PM CDT Tue Oct 7 2025

The semi-permanent subtropical ridge that has largely controlled
the weather over our region the past few weeks will continue to be
the primary influence for us going through the remainder of the
week and into the weekend. This will result in more dry weather
with seasonably warm temperatures that are a little above normal.

Through tonight: Scattered light showers associated with a weak
cold front pushing slowly southeast into the area will diminish
quickly with sunset. The combination of the weak frontal boundary
moving into a very humid boundary layer will result in areas of
fog over southeast portions of the forecast area, and we are
messaging for a limited threat of dense fog. /EC/

Wednesday through Monday: Any fog should lift and dissipate by
mid morning. Thereafter, the weak cold front will continue to
shift south and eventually out of the area as we go into
Thursday, bringing a noticeable decrease in moisture and humidity.
This will significantly limit rain chances over the remainder of
the week into early next week. While temperature change will be
less significant behind the front, and the drier air will allow
daytime temperatures to remain close to normal, overnights and
mornings should be noticeably cooler, albeit still near seasonal
norms. /DL/EC/

.AVIATION...
(18Z TAFS)
Issued at 1223 PM CDT Tue Oct 7 2025

A mix of VFR/MVFR flight categories will prevail at area TAF
sites through much of the period. This is mainly as a result of
low stratus across the area as a weak frontal boundary slowly
pushes east through the area. While stratus will continue to be an
issue overnight, fog development will be possible across mainly
east and southeast Mississippi toward day break Wednesday. Some of
this fog could be dense, lowering visibilities to MVFR/IFR
categories for a few hours. Both fog and low stratus will erode
through the morning Wednesday, with a return to mainly VFR
categories anticipated heading into the Wednesday afternoon. Winds
in the wake of this boundary will become northwesterly between
3-5 knots, but will become calm to light from the northwest this
evening and overnight. /19/
