.DISCUSSION...
Issued at 244 PM CDT Mon Apr 7 2025

Quiet conditions this afternoon behind a boundary with good cold
advection limiting highs despite full sunshine.  The brisk north
winds die off quickly this evening as pressure gradient relaxes with
light and variable winds overnight.  The light winds, clear skies
and dry airmass are expected to allow temperatures to fall quickly
with lows falling into the low to mid 20s in most areas.  Warm
advection kicks in on Tuesday with strengthening south surface winds
and a nearly 10 degree rebound in highs.  Continued isentropic lift
through the day into the evening will eventually lead to increasing
clouds.  Any precipitation is initially fighting dry near surface
air into Tuesday night with saturation deepening across the south
and east overnight.  Some light isolated showers are possible after
midnight across the south and east but with light amounts as
moisture remains limited.

Another shortwave approaches the state from the northwest late
Wednesday night into Thursday morning with additional forcing.
Scattered showers are expected once again late Wednesday night into
Thursday across central Iowa with this wave.  Moisture remains
limited with precipitation staying scattered and light.  Quiet
weather returns on Friday and into Saturday with warm advection
intensifying.  The next shortwave passes through the Midwest on
Sunday/early Monday timeframe but once again, the bulk of forcing
and moisture are not across Iowa with any chances for precipitation
staying limited.
