.DISCUSSION...
Issued at 135 PM CDT Sat Oct 11 2025
Tonight through Sunday...
Stagnant but seasonable conditions will continue this weekend. The
Gulf Coast region will remain locked in between synoptic ridging to
the west over south TX and cutoff low over the east. This will keep
northeasterly low level flow and dry advection of low humidity
aloft/precipitable water below 0.75 inches through the weekend.
Dewpoints should mix out in the 47F to 53F range east of I55 and 54F
to 60F to the west. Combined with seasonably warm highs, afternoon
minimum relative humidity could fall into the 30 to 40 percent
range. As the gradient relaxes, lows could fall near seasonable
levels, as low as 48 to 50F in the Hwy 45 corridor, outside of areas
northwest of the Natchez Trace. Both low relative humidity and
drying fuels support continued advertisement of Limited fire danger
in GHWO, mainly east of I55 through Sunday. However, this is a low
end risk. This may persist into early next week but light winds may
limit potential.
Next week into next weekend...
Ridge to the west will propagates eastward across the ArkLaTex into
the Gulf Coast region through midweek. As it moves near or over the
northern Gulf, mean ridging will fall from around 593 to 595DM to
around 586DM into mid to late week. Low level trajectories will
become more southerly into late week, helping mean moisture profiles
to increase. Dry period is expected through the work week, with
continued curing of dry fuels and afternoon warmth and low humidity
(85F to 90F highs and 28 to 40 percent minimum RHs). An increase in
southerly return flow will help highs and lows moderate seasonably
warm (highs some 8F to 12F above by mid to late week and lows some
10F to 15F by late week). There are some indications of frontal
convergence into next weekend and combined with an increase in mean
moisture, some scattered rain probabilities next weekend (up to 30
percent). /DC/
