The episode as NWS ABR wrote it up.
Severe drought continued across most of central and north central South Dakota throughout much of September west of the James River Valley. There was some improvement towards the end of September. Periodic episodes of precipitation across the region had prevented widespread worsening of the drought conditions. The severe drought had began across the region in early June. Several counties still had burn bans in place. Crops and pastureland continued to suffer from the the long term dryness. The spring and winter wheat production was at its lowest in years and more than 60 percent below long-term norms. Only 670,000 acres of spring wheat were harvested in the state this year, the lowest since the big drought year of 1936 when only 550,000 acres were harvested.

Area Forecast Discussion...UPDATED National Weather Service Aberdeen SD 1228 AM CDT Fri Sep 1 2017 .UPDATE... Issued at 1225 AM CDT Fri Sep 1 2017 See updated aviation discussion below. UPDATE Issued at 934 PM CDT Thu Aug 31 2017 Radar/satellite showing good shower/storm development into northwest SD this evening. Will see how this holds together as it moves east along with any new development. Current forecast POPs look good. && .SHORT TERM...(This Evening through Friday Afternoon) Issued at 247 PM CDT Thu Aug 31 2017 High pressure to the east is enabling some stratus to advect northwest into areas along and east of I-29. This stratus is likely to stay in place until the advancing low pressure system and cold front push it out on Friday. Showers and isolated thunderstorms have begun to fire already west of the James Valley on some shortwave energy and the southerly flow ahead of the front. Interestingly, none of the CAMS show precip that far east, but the GFS does. The NAMNest is starting to catch up with the current radar trends, but keeps any showers out of the James Valley until near midnight. The shortwave trough is leading the way with the front trailing slowly behind and slated to reach central SD Friday afternoon before stalling. If the timing and placement are correct, this means winds will not be as strong over central SD during peak heating time and fire concerns will be minimal. Showers and isolated thunder will progress eastward through the day on Friday. .LONG TERM...(Friday Evening through Thursday) Issued at 247 PM CDT Thu Aug 31 2017 An up then down temperature trend for the extended with mainly dry conditions. There is still some uncertainty over temperature expectations for Saturday with the GFS/ECMWF in different camps on timing of a warm surge. GFS mixes us to around 700mb which would yield highs in the low to mid 90s, while the ECMWF is slower with the warm surge and thus low to mid 80s, which is closer to the blended guidance. Trended temperatures Saturday up about 2-3 degrees but not as warm as the GFS potential. Sunday looks more confident with the warm air overhead, with 850mb temperatures a standard deviation above climo. Blended guidance is still quite a bit lower then the potential with mid/upper 80s and low 90s. GFS mixes us to around 650mb, and using the mixed tool to 700mb still yields to around the century mark. Added about 5 degrees to blended guidance. A dry, cold frontal passage expected Sunday night early Monday with a transition to a Canadian airmass. 850mb temperatures bottom out around 2 standard deviations below climo for Wednesday morning. Might see a few readings in the upper 30s under favorable radiational conditions. && .AVIATION...(For the 06Z TAFS through 06Z Friday Night) Issued at 1225 AM CDT Fri Sep 1 2017 Scattered showers, along with some isolated thunderstorms, will be moving across the region from the west overnight and Friday as an upper level low pressure trough moves in. These will likely affect the stations at or in the vicinity. Otherwise, expect IFR/MVFR stratus to affect ATY and ABR tonight as low level RH will be high. Expect these lower ceilings to remain in at ATY through much of Friday. && .ABR WATCHES/WARNINGS/ADVISORIES... SD...None.
