.DISCUSSION...
Issued at 141 AM CDT Fri Sep 5 2025
FRIDAY (Today) THRU SATURDAY:
Currently, Arkansas is under the influence of warm and
southeasterly flow which is situated on the upper lvl western
periphery of a subtropical ridge. It is this feature which has
resulted in slightly warmer than average temperatures compared to
early September normals. However, considerable changes will begin
Friday morning into Saturday as an upper lvl trof is digging over
the Central and Eastern regions of the CONUS.
This upper lvl feature will coerce a sfc cold front to push across
Arkansas beginning Friday morning (this morning) across northwestern
Arkansas and track south-southeastward across the state, eventually
tracking into Louisiana paralleling the I-20 corridor by Saturday
morning.
Guidance consisting of the GFS, ECMWF, and NAM are in cohesion with
regards to positioning of this feature. The only small deviations
are the timing and amount of rain and storm development associated
with the movement of this front as it track across the Natural
State. The ECMWF continues to be a slightly quicker and drier
solution. However, guidance across the board is trending with a
quicker moving cold front and rain and storm activity clearing out
of central Arkansas by Saturday afternoon.
Likewise, now in the range of short-term model guidance, are on
board with these CAMS solutions such as the RAP and HRRR moving all
rain and storm activity into southern Arkansas by Saturday
afternoon.
Expect rain and thunderstorm activity to begin impacting northern
Arkansas later Friday morning into midday on Friday, central
Arkansas by late Friday afternoon into Friday evening, and southern
Arkansas into Friday evening and Friday night. The progression of
this cold front is slow and precipitation will be present behind
this anafront. Rain and isolated storm activity will taper off on
Saturday from north to south across the state throughout the day.
High temperatures today will be dependent on the placement of the
cold front and seasonable temperatures to temperatures a few degrees
above average can be anticipated across much of central and southern
Arkansas; whereas, northern Arkansas will feel high temperatures
around 10 degrees below normal as the cold front will have already
tracked through part of northern Arkansas by this afternoon.
On Saturday, with the FROPA complete across Arkansas, expect
temperatures with respect to morning lows and afternoon highs
roughly 10 degrees below average compared to normals for this time
of the year.
SUNDAY THRU THURSDAY:
Sfc high pressure will settle back in behind the cold front and lead
to a Sunday and Monday with temperatures slightly below normal with
fair and dry weather conditions will persist through the remainder
of the forecast period. The most noted difference over this period
will be the gradual increase of temperatures back to seasonal
averages or near normal for early to transitioning into mid
September by Thursday.

(18Z TAFS)
Issued at 1229 PM CDT Fri Sep 5 2025
A cold front will push through the state this evening through the
overnight and early morning hours. Along and ahead of the front,
the front will generate shower and thunderstorms that will bring
periods of MVFR with some intermittent IFR/LIFR ceilings possible
to all terminals. Surface winds will be light and out of S/SW
ahead of the boundary, then veer N/NW shortly after FRPA before
turning N/NE during the early to mid morning hours. Thunderstorm
near or over terminals will also bring strong gusty winds for a
brief period along with frequent lightning and locally heavy
rainfall.
