The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Rapid City, SD wrote its last area forecast discussion before the first event at Jun 28, 1:55 PM MST, 23 minutes earlier.
Area Forecast Discussion For Western SD and Northeastern WY National Weather Service Rapid City SD 255 PM MDT TUE JUN 28 2016 .SHORT TERM...(This Evening Through Wednesday Night) Issued at 255 PM MDT Tue Jun 28 2016 Current surface analysis shows low pressure over northeast WY, with frontal boundary extending south across eastern WY and the lee of the CO Rockies. Upper level analysis shows high pressure centered over eastern UT, with ridge extending north across the Northern Rockies. Weak shortwave noted on water vapor imagery crossing southeast MT and eastern WY, moving southeast through our area late this afternoon and evening. Instability is rather strong to the east of the boundary, with cape values of 2000 to 3000 j/kg currently from far northeast WY to southwest SD. A few storms developed over the Black Hills around midday, but struggled to move off the hills with strong cap in place. Cap is eroding now across the plains and more robust storms are developing across northeast WY ahead of the shortwave. Temps are in the 80s to around 90 degrees with southeasterly winds at most locations, especially to the east of the boundary. Active weather is expected across a good portion of the cwa over the next few hours, especially from northeast WY through southwest SD. Strong to severe storms can be expected with large hail and strong wind gusts the main threats. An isolated tornado cannot totally be ruled out, but the threat looks to be rather low with low level shear on the weaker side. The stronger storms should shift toward southern portions of northeast WY and southwest SD by early evening, with most of the stronger activity moving south-southeast out of the cwa by mid evening. Isolated showers and storms will likely linger across the area overnight, especially across southern SD. Lows will be in the mid 50s to lower 60s. Wednesday will see more showers and thunderstorms across the area, mainly during the afternoon and evening hours, as another shortwave rotates across the area. At this point, the threat for severe storms looks to shift a bit further south, but will still cover most of the Black Hills area and much of the southwest SD plains. Hail and wind will be the main threats again. Temps will be a bit cooler, with highs mostly in the 80s across the plains, 70s in the Black Hills. Activity should become more isolated again overnight, with lows in the mid 50s to lower 60s. .LONG TERM...(Thursday Through Tuesday) Issued at 255 PM MDT Tue Jun 28 2016 Progressive westerly to northwesterly upper level flow will continue through the extended period with relatively moist southeasterly upslope flow at the lower levels. As a series of disturbances push through the area, the persistent flow of low/mid level moisture will aid in the development of diurnal convection nearly every day. Most days the coverage will be limited, with only isolated to scattered thunderstorms. Deep layer shear aloft will support the threat of severe storms; however, the lack of strong upper level forcing will keep the coverage of severe storms limited. Temperatures will remain slightly warmer than average, with highs mainly in the 80s through the weekend leading into a more significant warm-up early next week. && .AVIATION...(For the 18Z TAFS Through 18Z Wednesday) Issued At 255 PM MDT Tue Jun 28 2016 Scattered to numerous thunderstorms this afternoon and evening. Some thunderstorms may be severe this afternoon and early evening, with large hail and damaging wind gusts. VFR conditions will prevail through the period except for local MVFR conditions near any thunderstorms. && .UNR Watches/Warnings/Advisories... SD...None. WY...None. && SHORT TERM...26 LONG TERM...MLS AVIATION...MLS
