$$What forecasters said that day
The local office's own words before this river flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Des Moines, IA wrote its last area forecast discussion before this river flood warning went out at Jul 1, 3:14 AM CDT, 1 hour 16 minutes earlier.
Area forecast discussion, Jul 1, 3:14 AM CDT, 1 hour 16 minutes before
Area Forecast Discussion National Weather Service Des Moines IA 314 AM CDT Sun Jul 1 2018 .DISCUSSION.../Today through Saturday/ Issued at 306 AM CDT Sun Jul 1 2018 Strong upper level low that has brought tremendous rainfall to parts of central Iowa tonight continues to churn over the northern Plains. Showers and thunderstorms are likely to continue over the next several hours as a persistent stream of anomalously moist low level flow remains focused on the state. On the positive side, mucape has weakened considerably over the last couple hours which has led to more disorganized activity as lower rainfall intensity. However, still can't rule out some places picking up another inch or so of rainfall. Precip chances diminish by mid to late morning as the upper level low pushes a cold front through and northwesterly winds advect a much drier airmass into the state. Relatively cooler and less humid conditions will be a welcome relief through the first few days of the week. However, a strong ridge will retrograde west and amplify over the central Plains by Wednesday, returning stifling heat and humidity back into the region. Peak heat index values for the 4th of July holiday and again on Thursday may push close to heat advisory criteria in the 100-105 range. Model guidance suggests dew points in the mid 70s, but this may be a little underdone especially considering the wet surface conditions and maturing crops. Shortwave trough rounding the top of the ridge looks to be robust enough to send a cold front through the state by Friday, which should bring temperatures back into the 80s. Precipitation forecast through the week remains somewhat uncertain, but the threat for more widespread excessive rainfall appears low as the main focus for thunderstorm activity hangs up north of the state. Models continue to generate spurious QPF as subtle shortwave shortwaves round the ridge mid- week, but these weak transient waves are typically tough to hang your hat on at this time range. Highest confidence in next round of precip will be with the aforementioned frontal passage Thursday night into Friday. Strong to severe storms may be a threat given the highly unstable air mass ahead of the front, however at this time it looks like weak flow aloft will be a limiting factor. && .AVIATION.../For the 06Z TAFS through 06Z Sunday night/ Issued at 1241 AM CDT Sun Jul 1 2018 Showers and thunderstorms will continue through the remainder of the overnight hours and into early morning. This will bring tempo restrictions of MVFR or lower due to low cigs and significant rainfall rates at times. Lingering MVFR cigs and a few showers are possible into Sunday afternoon before we begin to clear out as this system departs the area. && .DMX WATCHES/WARNINGS/ADVISORIES...
