SSTWhat 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 Sioux Falls, SD wrote its last area forecast discussion before this river flood warning went out at May 8, 6:23 AM CDT, 3 hours 19 minutes earlier. Its key messages:
- Showers and isolated storms expected today. Some storms could be strong to severe and bring another round of meaningful and locally heavy rainfall. Confidence is low in severe weather threat as well as location of heaviest rainfall.
- Warmer and mainly dry conditions move in for the weekend. Continued warm with renewed rain chances by mid week.
Area forecast discussion, May 8, 6:23 AM CDT, 3 hours 19 minutes before
Area Forecast Discussion National Weather Service Sioux Falls SD 623 AM CDT Wed May 8 2024 .KEY MESSAGES... - Showers and isolated storms expected today. Some storms could be strong to severe and bring another round of meaningful and locally heavy rainfall. Confidence is low in severe weather threat as well as location of heaviest rainfall. - Warmer and mainly dry conditions move in for the weekend. Continued warm with renewed rain chances by mid week. && .DISCUSSION... Issued at 334 AM CDT Wed May 8 2024 CURRENTS: Pleasant conditions this morning with calm to light winds and some clouds across the Hwy 20 corridor and south central SD. A few weak echoes are visible on radar in these areas as well, but dry low levels is precluding any measurable precip. Temperatures through 08z/3 AM CDT are in the 40s to mid 50s, and expect widespread 40s by daybreak. Surface low is located over north central NE, with upper low across northwestern SD/southeastern MT. TODAY AND TONIGHT: Some uncertainty today in the forecast, as models disagree on where exactly the stacked low pressure meanders and where the associated fronts are. This will impact everything from rain chances to winds to severe weather potential through today. Guidance shows the surface low by 18z/1 PM CDT anywhere from northeastern NE to over Sioux Falls to over IA/MN border. By this time, the mid and upper low are located in central and southwestern SD, respectively, with roughly the same amount of variability as the surface low. All this to say the subtle differences are leading to lower than average confidence in precipitation forecast today. Overall, trends in the hi-res and other guidance show showers developing by late morning into the early afternoon hours, generally isolated at first becoming more widespread through the later afternoon and early evening hours. Although risk is low, we could see a few strong to severe storms. Instability increases fairly quickly this morning into the early afternoon to around 1000 to as high as 1500 J/kg. Steep mid level lapse rates over 7 deg C/km with this instability and increasing bulk shear would support some large hail of quarter to half dollar sized. Think that damaging wind gusts to 60 mph are less of a concern with DCAPE at or less than 500 J/kg, but can't entirely be ruled out. As we sit under the upper low, funnels and/or landspouts are also possible. Landspout/non-supercell tornado threat is additionally supported by 0-3 km MUCAPE and 0-1 km MLCAPE both over 500 J/kg and steep low level lapse rates (over 8 deg C/km). This threat will also be variable in location depending on where the warm front ends up, which would provide another focus. Folks should stay weather aware today and this evening. Regarding heavy rain potential, with the variance in model solutions, it is difficult to say exactly where the highest QPF will be realized and how much. Taking a look at the 08.00z deterministic guidance, the axis of heaviest precip ranges from the Hwy 14 corridor to north central IA. Ensemble guidance (outside of the HREF and GFS) shows a less than 10% chance of any portion of our area seeing over 0.50" of rain. However, the GFS ensemble paints a 50% chance over the MN/IA border stretching east. The HREF is the most bullish - with most locations across southwestern MN and northwestern IA having a 60-90+% chance of over half an inch of rain. Think that some folks will see 0.50-0.75" through Thursday, with locally higher amounts possible in thunderstorms. This could lead to localized ponding and some small rises on local creeks/streams if the heavier precip falls in our more saturated areas. Otherwise, highs today in the 60s to lower 70s with increasing clouds. Winds will be variable as the low moves across the area, with sustained winds 5-15 mph and gusts to 20-25 mph. Showers and isolated storms continue to slowly sink south during the overnight hours. Lows fall into the 40s. TOMORROW THROUGH THE WEEKEND: Our persistent stacked low pressure system is shoved out of the way Thursday as another wave drops south, keeping scattered shower/isolated storm chances in play. We'll see drier weather for Thursday night into Friday. We'll remain in northwesterly flow with another wave or two skirting by to the east over the weekend which could bring the return of low end shower and storm chances. Still some variability in the timing/location of the wave(s), so have left the NBM for now. Periodically breezy winds expected. A warming trend is also expected, with highs warming into the 70s by the weekend and lows in the 40s and 50s. Some 80 degree highs are possible by Sunday. EARLY TO MID NEXT WEEK: More zonal flow is progged to move over the Plains by early next week, with models varying widely on the tracks of waves/troughs. Generally expect near to above average temperatures to continue. Rain and storm chances also return, greatest currently expected in the middle of the week with a more robust trough. && .AVIATION /12Z TAFS THROUGH 12Z THURSDAY/... Issued at 614 AM CDT Wed May 8 2024 Outside of convection, expect VFR conditions to prevail for much of the period. Showers and storms may reduce category to MVFR or IFR for brief periods. Guidance is continuing to poorly handle the isolated to scattered convection beginning late this morning/early this afternoon through much of the period, but tried to average the timing within the latest guidance for convective PROB30 groups. More widespread precipitation is possible toward the end of the period along and south of I-90, which could bring a period of more widespread near MVFR ceilings. Winds will be variable in direction today as low pressure slides over the area. Expect gusts at times around 20 knots. && .FSD WATCHES/WARNINGS/ADVISORIES... SD...None. MN...None. IA...None.
