.DISCUSSION...
Issued at 331 AM CDT Fri Oct 18 2024

Today and Tonight...The region will remain under the control of
ridging aloft today, despite its axis residing just east of the
forecast area.  This`ll result in moisture aloft beginning to
increase across the CWA, which will be in the form of mainly some
scattered high clouds lifting northeast through the region during
the period.  Meanwhile at the surface, high pressure centered across
Appalachia will remain wedged into the forecast area.  This will
result in east to east southeast winds between 5-8 mph across the
CWA this afternoon.  Overall, this setup will continue to yield
quiet weather across the region today and tonight.

Highs will be a touch warmer today, compared to yesterday, as they
top out in the low and middle 70s. Once again, the airmass will
remain rather cool and dry across the area, as dew points generally
mix into the 30s.  With soil conditions remaining dry, coupled with
afternoon minimum relative humidity values between 25-30%, a
"limited" fire danger threat continues across the area today as
extra caution is advised with any open burning.

Cool conditions will exist again across the area tonight.  With a
few clouds overhead, look for lows to range in the mid and upper
40s. /19/

Saturday through next Thursday...Extended forecast remains on
track as dry and quiet conditions continues over the ArkLaMiss
region. Expect seasonal highs and below to near seasonal lows
through the period.

Upper-lvl ridging/surface high pressure will remain in place over
the eastern/southern CONUS over the weekend and into next week.
Currently, RH values look to range between 25-35% into the weekend.
With continued dry soil conditions, it`s possible the "limited" fire
danger threat may need to be extended into the weekend. RH values
are expected to increase into the new work week. Overall pattern
will shift by mid-week as the ridge pattern transitions into a more
broad trough axis. This will allow for a shortwave disturbance to
push a dry frontal boundary towards the area toward the end of the
period; however, rainfall is not expected with this system. /SW/
