NWS Sioux Falls, SD wrote its last area forecast discussion before the first event at Jun 3, 5:07 PM CST, 13 minutes earlier.
Area Forecast Discussion National Weather Service Sioux Falls SD 607 PM CDT Sat Jun 3 2017 .SHORT TERM...(This evening through Sunday) Issued at 256 PM CDT Sat Jun 3 2017 Frontal boundary extending from Yankton to Sioux Falls to Slayton will continue to slowly sag southeastward and will finally exit the area by late tonight. Very dry airmass has prevented precipitation from developing along this boundary so far this afternoon, however with strong heating and mid level moisture beginning to pool some ahead of the front, expect spotty showers to begin popping up in the cumulus field now developing in northwest Iowa, far southeast SD and southern Minnesota. Certainly looks like enough elevated instability for thunderstorms, but shear profiles do not support severe thunderstorm activity. Can't rule out some small hail or gusty winds in some of the storms. With the loss of daytime heating mid evening, the front weakens and the showers will quickly diminish. With plenty of sunshine, modest mixing under northwest flow, and warm thermal profiles, Sunday will be another hot day. Expect temperatures to be similar to today. Given that most locations heated out warmer than guidance, went ahead and bumped highs a degree or two for Sunday. Again, we should see highs in the mid 80s to lower 90s. Northwest winds will not be particularly strong, and mainly in the 5 to 15 mph range, so overall it looks like a pleasant summery Sunday. .LONG TERM...(Sunday night through Saturday) Issued at 256 PM CDT Sat Jun 3 2017 Upper level ridge will continue to bring warm and mostly dry conditions through mid-week. The work week starts slightly cooler than Sunday, as a backdoor cold front slides southward into the area Sunday night into Monday. Dry air and northeasterly flow will bring highs in the upper 80s west of I-29, and in the lower 80s east...with lower readings around Buffalo Ridge area. An upper wave over southern Canada/Northern Plains will move southeastward, while at the surface a frontal boundary will develop across central Dakotas Tuesday night into Wednesday. Profiles suggest an increase in moisture associated with this system, but there is no enough forcing/dynamics with it. Moderate instability, strong theta-e advection and southerly surface winds will support scattered showers and isolated thunderstorms. Most of the precipitation on Tuesday will occur west of I-29, and increases eastward early Wednesday morning. As the main upper low pressure slides southeastward across the Upper Mississippi Valley, isolated showers and thunderstorms will be possible through the weekend. Uncertainty in timing and location remains among models; therefore kept it as slight chances. Besides periodic chances of precipitation, the second half of the extended looks mild with near or slightly above seasonal temperatures. Highs will generally stay from the lower to mid 80s, and lows in the upper 50s to lower 60s. && .AVIATION...(For the 00Z TAFS through 00Z Sunday evening) Issued at 606 PM CDT Sat Jun 3 2017 Line of high-based showers/thunderstorms drifting slowly east to southeast across northwest Iowa early in the period. Storms are expected to weaken with loss of heating toward sunset, but thunder may impact KSUX vicinity through 01Z. After storms diminish in the mid-late evening, looking for clear skies and light winds through the TAF period. && .FSD WATCHES/WARNINGS/ADVISORIES... SD...None. MN...None. IA...None.
