.DISCUSSION...
Issued at 159 AM CDT Fri Aug 22 2025

Through Sunday: Isolated showers an patchy fog are ongoing early
this morning ahead of a weak front pushing across the area. This
front will stall and begin to fall apart today roughly along the
Gulf Coast to our south then extending northward into Alabama. In
the wake of this front, relatively drier air is advancing into
the region. Today more areas will begin to see dewpoints mixing
down into the 60s, and we`ve already seen PW fall by nearly an
inch over the northern half of the area. The drier airmass will
still allow for seasonably warm days through this weekend, but it
will also make for pleasantly cooler mornings. No heat stress
issues are anticipated, with heat indices remaining below 100 in
most areas even in the middle of day. Closer to the front, there
will still be potential for isolated to scattered diurnal
convection, across areas like central LA, south MS, and far east
MS.

Monday through Thursday: A reinforcing front will move across the
area Sunday night into Monday, bringing a more substantial push
of dry air along with a bit of a drop in temperature. By Tuesday
and Wednesday, high temps below 90 will become more common, and
most areas will have morning lows in the 60s. A few cooler spots
in north MS could even touch the upper 50s by Thursday morning.
Rain chances will be quite limited by Monday, though isolated
shower chances may return later in the week. With the increasing
dryness, we will need to pay greater attention to fire weather
concerns. Daytime RHs are forecast to fall as low as the 25-30
pct in some areas by Monday, and with stronger mixing in the dry
conditions, winds could become a relevant factor. Otherwise, no
other hazards are on the horizon in the long term portion of the
forecast. /DL/
