.DISCUSSION...
Issued at 128 PM CDT Mon Sep 29 2025
Cumulus clouds have developed across parts of Iowa this afternoon
associated with a shallow plume of mid level moisture into the area.
The large blocking pattern across the central US will continue to
dominate sensible weather over Iowa throughout this week. Late
tonight and into Tuesday the western US trough will sink
towards the area, increasing convergence over western and
northern Iowa with a narrow moisture plume. While a few CAMs
squeeze out weak echos in simulated reflectivity, soundings are
fairly dry. A few sprinkles may occur with increasing cloud
cover, but any notable precipitation is unlikely. That cloud
cover may put a damper on temperatures by a few degrees, but it
will still be quite warm. Steady southerly flow through the
week will help keep temperatures in the mid to upper 80s, 10-15+
degrees above seasonal averages which are in the low 70s this
time of year. Precipitation chances return this weekend as the
western trough finally shifts east, however uncertainty remains
in terms of timing and placement at this time range and will
depend in some part on how the Atlantic systems evolve.
