MohrWhat 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 Aberdeen, SD wrote its last area forecast discussion before this river flood warning went out at Apr 20, 12:32 AM CDT, 47 minutes earlier.
Area forecast discussion, Apr 20, 12:32 AM CDT, 47 minutes before
Area Forecast Discussion...UPDATED National Weather Service Aberdeen SD 1232 AM CDT Fri Apr 20 2018 .UPDATE... Issued at 914 PM CDT Thu Apr 19 2018 No changes planned to the forecast tonight. But, local streams, creeks and rivers are being monitored closely. With the warm up comes a faster rate of snow/ice melt within area drainage basins. Between recent reservoir water releases and considerable snowmelt, several rivers and creeks within the James River valley and the Big Sioux River valley (up in the Glacial Lakes region on the Prairie Coteau) have responded and are either running at bankfull or rapidly approaching bankfull. South Branch Mud Creek near Rauville has gone above flood stage this evening. An Areal Flood Advisory was issued a short time ago for that area, after coordination with the Codington County Sherrif's Office. Additional Flood-related products may be needed within the next 24 hours for some locations throughout northeast South Dakota (and possibly west central Minnesota). Flooding situations can be particularly dangerous at night. Don't drive through areas where water covers the road! UPDATE Issued at 640 PM CDT Thu Apr 19 2018 See below for an aviation forecast discussion for the 00Z TAFs. && .SHORT TERM...(This Evening through Friday Afternoon) Issued at 300 PM CDT Thu Apr 19 2018 Though largely passing south, a large cut-off low currently across the 4-corners region of the US will migrate east towards the Plains and impact our weather during the short term. Cloud cover will be on the increase this evening into Friday which, along with southerly surface winds, should prevent temperatures from dropping too far below the low 30s/upper 20s tonight. Conversely, increasing and eventually widespread cloud cover Friday may limit daytime high potential to the upper 40s and mid to lower 50s. Models do bring light showers into southern South Dakota by the noon hour Friday, however temperatures should be warm enough for an all rain event. POPs continue through the day Friday mainly across central South Dakota, but totals only on the order of hundredths of an inch of moisture are expected. .LONG TERM...(Friday Evening through Thursday) Issued at 300 PM CDT Thu Apr 19 2018 The extended period begins with high pressure exiting to the east and low pressure over the lee of the Rockies. The southern portion of this low will slide southeastward to Texas by midday Saturday, dragging an area of precipitation with it. The northern fringe of this precipitation looks to possible affect western and southern portions of the CWA Friday night into Saturday morning, but amounts will be fairly light and the precipitation should be in the form of rain. The Saturday afternoon through Sunday night time period looks to be dry with weak high pressure in place. Attention then turns to an upper level shortwave and frontal boundary forecast to track across the area, bringing a more well organized area of rain to the region. Timing continues to be the question, with the Canadian model being just about 6-12 hours faster than the GFS and ECMWF. Will keep POPs going during the Monday through Tuesday morning time frame for now. May see one quarter to one half inch of rain in some locations, and cannot rule out a period where the rain may mix with snow late Monday night, with minor accumulations possible. The remainder of the extended period will be dry with high pressure moving in control Wednesday and Thursday. In general, temperatures will be leaning toward a warming trend. Highs will be in the 50s on Saturday, and in the 50s and 60s Sunday and Monday. Cooler temperatures move in with the rain Tuesday, with highs back down in the 50s before warmer air returns, with highs mainly in the 60s Wednesday and Thursday. && .AVIATION...(For the 06Z TAFS through 06Z Friday Night) Issued at 1231 AM CDT Fri Apr 20 2018 VFR conditions are expected through most of the TAF valid period. By late afternoon, some rain showers may be working northward into the region (mainly affecting KPIR), and after 00Z some sub-VFR cigs may be developing. Currently, not a lot of confidence in sub-VFR conditions setting up Friday evening/night. Will continue to monitor. && .ABR WATCHES/WARNINGS/ADVISORIES... SD...None.
