.DISCUSSION...
Issued at 121 PM CDT Thu Sep 18 2025
Embedded impulses associated with a 500 mb trough over the northern
Plains will dig towards the FA on Friday, triggering a low risk
of isolated showers and storms mainly across portions of
southeast Missouri and southern Illinois. Bumped up NBM PoPs in
the afternoon to account for the slightly wetter 12z CAMs that
also indicate uncertainty on placement. The RAP13 shows modest
instability and poor shear, but steep low-level lapse rates may
support a stray gusty storm.
Daily chances continue through the weekend, especially on Sunday as
a shortwave moves through. Energy over the northwest CONUS will
set the stage for a fairly unsettled week as a cut off 500 mb
low develops over the central CONUS by Wednesday. There remains
a large spread among model guidance regarding the evolution of
the synoptic details, but the general consensus is for shower
and storm chances to become more probable through the middle of
the week. The GFS remains more progressive and drier compared to
the ECMWF that holds the aformentioned low back in the vicinity
of the FA. Should the slower scenario be correct, more
impactful rainfall upwards of 1 to 2+ inches would be possible.
Regardless, increased rain chances along with cloud cover and
more seasonable temperatures in the low to mid 80s is expected.
