$$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 Jun 10, 7:29 AM CDT, 2 hours 53 minutes earlier.
Area forecast discussion, Jun 10, 7:29 AM CDT, 2 hours 53 minutes before
Area Forecast Discussion National Weather Service Des Moines IA 729 AM CDT Sun Jun 10 2018 ...Updated for 12z Aviation Discussion... .SHORT TERM.../Today through Tonight/ Issued at 416 AM CDT Sun Jun 10 2018 Rest of this Morning... Focus is on eastern Nebraska. At 08z Sun, GOES-R IR imagery clearly picking up on an MCS that was developing over east-central Nebraska and slowly propagating towards Iowa. This MCS cluster is associated with a shortwave/vort max area that is being initiated well with most models. GOES-R showed cloud top temps cooling as SPC Mesoanalysis showed the cap breaking over the heart of the cluster. Well-phased with PVA of this system is a 40 to 50KT LLJ oriented SW- NE. Along the nose of this LLJ is strong low-level frontogenetical forcing that has likely contributed to ascent processes to help these storms punch through this cap. MUCAPE values are roughly around 2000 J/KG from these storms and through Iowa. The orientation of the instability axis and frontogenetical forcing is NW-SE, so am expecting the general cluster of storms to favor a more easterly/southeasterly track as the near the DMX CWA. Timing-wise, am expecting these storms to be in the west-central portion of the DMX CWA around 12z to 18z... which is not a climatologically favored time for severe weather. In short, forcing parameters wane through this time-frame, so would expect storms to gradually weaken as they traverse through west-central Iowa. QPF amounts are generally one-tenth to one-quarter of an inch. Temperatures today will be tricky. Somewhat thick, low-level stratus will be in place over northeastern Iowa associated with the previous days rainmaker of a shortwave. These clouds will slowly move northeastward throughout the daytime with this system. If clouds linger into the afternoon, Mason City & Waterloo may struggle to get out of the mid 70s... while southwestern Iowa may make flirt with the mid 90s if the track and subsequent cloud cover from the Nebraska system keeps the easterly component in its track. If the storms hold to the Des Moines metro during the early afternoon, max temperatures may be held to the low 80s... if the system dissipates more rapidly than expected, low 90s would seem more prudent... so for now, am near the middle. This Afternoon/Tonight... Another round of moderate to heavy rainfall possible tonight as the LLJ mentioned above creeps into western Iowa. Models have had a westward trend with this LLJ, so will need to watch and see if this continues. If the trend does continue, axis of highest precip amounts will need to be shifted to west of I-35. At this point in time, Axis of heaviest precip from Mason City through Marshalltown. Important to note that Mason City area has received substantial rain over the past few days... so this rainfall is certainly not going to alleviate flooding issues in that area. MUCAPE values to be near 1000 J/KG. PWATs around 1.5 to 1.75 inches... +1 to +2 std dev once again. Ultimately, heavy rainfall/flooding potential in already rain- soaked areas biggest threat. Severe weather threat fairly low, with damaging winds the secondary threat. .LONG TERM.../Monday through Saturday/ Issued at 416 AM CDT Sun Jun 10 2018 Potential for some elevated convection to be ongoing Monday morning across the northeast and it is possible some convective elements will linger through the morning in that region. The activity should diminish by late morning and into the early afternoon as drier mid level air arrives. Elsewhere, a capping inversion around 800 mb should limit any convective potential until later in the day. Over all trends are a bit slower on the upper level short wave and surface boundary arriving on Monday. Storms should develop as the boundary arrives by mid to late afternoon as the cap erodes. Similar thinking to SPC SWODY2 with generally multicells developing in a highly unstable environment. Broad CAPE through the mid levels will supports good updraft accelerations and large hail good 0-3 km Theta-e differences of 30-35k and DCAPE approaching 1500 will support cold pool development and lead to a damaging wind threat. All guidance is suggesting at least a weak low pressure depression lifting up along the boundary by the afternoon. While the GFS wind fields are not capturing this, there should be a little better deep and low level shear in place immediately north and east of the surface low. This region could become supportive of isolated supercell development and could have an attendant tornado threat in addition to very large hail and damaging wind gusts. Locally heavy rainfall will remain a concern until the boundary finally exits central Iowa as PWATs increase to 1.75-2 inches ahead of the boundary. Initial storm motions will also be seasonably slow and in the 5 to 20 kt range. Any supercells in particular could drop a significant amount of rain given expected slow motions. Finally, northeast Iowa could again be the target for heavy rainfall as more widespread storm development looks to focus on that region. Will certainly need to monitor that region as much of the Shell Rock and Cedar River basins are running high. Storms will end from west to east Monday night and will be followed by high pressure. Tuesday should be an outstanding day with lighter winds, dew points in the 50s leading to low humidity and high temperatures in the upper 70s to mid 80s. Wednesday will be similar though with the area of high pressure beginning to shift east, temperatures and dew points will be a bit higher that Tuesday. There will be a low chance for late afternoon thunderstorms over the northwest as theta-e advection begins to move back into the state. More widespread storms are expected Wednesday night into early Thursday. Additional scattered storms could occur Friday into Saturday as the upper flow becomes more southwesterly allowing the weather to remain active. && .AVIATION.../For the 12Z TAFS through 12Z Monday morning/ Issued at 727 AM CDT Sun Jun 10 2018 Inserted thunder into KDSM from roughly 8 am through 930 am or so this morning, and then again this evening. Have thunder in at other TAF sites at various times late this afternoon and evening. Eastern Iowa appears much more likely to receive storms than western Iowa after this morning. Non-thunderstorm winds should generally be under 10 kts throughout the TAF period. && .HYDROLOGY... Issued at 416 AM CDT Sun Jun 10 2018 Primary concerns for river flooding remains along the Winnebago, Shell Rock and Cedar Rivers and along some smaller streams including Willow Creek and Flood Creek. Pockets of heavy rainfall occurred with Saturday evenings storms especially along the Winnebago basin and along the Shell Rock just south of Nora Springs. Stream gages have resumed rising along the Shell Rock river at Marble Rock and Packard and there is another surge coming down the Winnebago that is 1-2 kcfs higher than what moved through the system 24 hrs ago. This could place the Shell Rock river level at Greene near to higher than what was observed Saturday morning though a bit difficult to forecast with the local surge currently arriving followed by the Winnebago River flow. The Winnebago flow may just attenuate and slow the fall at Greene rather than cause an additional rise. The currently forecast near Clarksville would not directly impact the community itself but would place water levels less than 1 ft from impact Highway 188 south of town. Additional storms will be possible across this area Sunday night into Monday morning and again late Monday into Monday night. River levels should be receding prior to this activity at most locations therefore it would take another heavy rain event upstream to overturn the trends. Another very heavy rain event would eclipse current levels. The Cedar River Basin is in a bit better shape though upstream, flooding is forecast near Charles City and certainly some Agricultural flooding is occurring. Again though, it will likely need another very heavy rain event to occur to cause significant issues. That said, the potential is there given the current setup through Monday night. && .DMX WATCHES/WARNINGS/ADVISORIES...
