.DISCUSSION...
Issued at 121 PM CDT Wed Sep 3 2025

An anomalously deep upper-level trough remains the dominant
feature over the CONUS and should remain so into this weekend.
Various shortwaves rounding the trough will keep rain chances in
the broader Deep South region through the weekend, with best
chances for rain in our forecast area being today and then Friday
Night into Sunday.

Tonight - the rain today is associated with a weak surface trough
and axis of pooled deep moisture. As afternoon and evening rain
comes to an end and clouds thin out, fog will be a concern. Have
included an "Elevated" threat for areas of dense fog across
northeast LA, and western/central MS overnight. Patchy fog is
possible elsewhere in MS and southeast AR.

As the trough axis translates eastward, high pressure from Canada
will build south into the Great Lakes region for early next week,
and upper-level ridging will begin to overspread the central
CONUS. The combo should result in drier weather next week and some
cooler weather again by early week. /NF/
