.DISCUSSION...
Issued at 304 AM CDT Sat Oct 11 2025

Today through Sunday Night...

Quiet and dry weather conditions will continue today across our CWA
thanks to high pressure ridging and light northerly flow under
mostly clear skies. Expect afternoon highs to peak into the low/mid
80s areawide. Quiet conditions will continue later tonight with
nighttime temperatures dipping into the upper 40s/low 50s for areas
along and east of I-55. Areas west of I-55 will see overnight lows
dipping into the mid 50s. Dry conditions will persist looking ahead
into Sunday with daytime highs peaking into the low/mid 80s.
Similar conditions are occur Sunday night under clear skies with
lows in the low/mid 50s.

Regarding the concerns for fire wx, near term guidance is still
showing RHs dropping to around 35-40% across much of our forecast
area today and Sunday with slightly lower RHs (around 30%) across
portions of east and southeast MS. These low RHs could cause some
low-end fire weather concerns. Because of this, we went ahead and
introduced a "Limited" risk for fire weather concerns through this
weekend mainly for areas east of I-55. RHs values will continue
to be monitored as we get through the weekend.

Monday through Friday...

Not much to talk about in the extended period. Heading into the new
work week, the upper ridge axis will shift slightly
eastward towards the ArkLaMiss Region. This will help maintain
the sfc high pressure system across the Deep South. Because of
this, dry conditions will continue across our CWA. Temperatures
will begin to trend upward looking ahead into the mid week as
global guidance continues to show shows surface trajectories
taking on a more southerly component. Dry and quiet conditions
will continue heading into Friday. /CR/
