A historic onslaught of swift moving severe thunderstorms with embedded tornadoes, followed by several hours of severe gradient winds and areas of blowing dust/smoke (and even a touch of wind-whipped snow) unfolded within South Central Nebraska on this Wednesday afternoon-evening, with the local area serving as the initiation zone of what would not only end up being the most impactful convective event on record during the month of December for the state of Nebraska (far eclipsing Christmas Day 2016), but also for other nearby states including IA/MN. In fact, the nearly continuous swath of damaging winds that stretched from south central NE/north central KS northeastward into southeast MN/western WI was officially declared a serial derecho...the first December derecho on record in the United States. Including nine confirmed tornadoes in South Central Nebraska (and 19 others that occurred in eastern NE), there were 28 confirmed tornadoes within the state...a remarkable fact considering that prior to this day only five Nebraska tornadoes had occurred in December since 1950! Focusing exclusively on the local South Central NE area going forward, the nine tornadoes consisted of five rated EF-1 and four rated EF-0. There were also dozens of measured reports of damaging winds in the 60-80+ MPH range (both thunderstorm/non-thunderstorm), including a peak thunderstorm gust of 85 MPH at Central Nebraska Regional Airport in Grand Island and a peak non-thunderstorm gust of 77 MPH by an unofficial mesonet in southwestern Clay County. Fortunately, there were no reported injuries, despite countless instances of damage primarily to irrigation pivots, outbuildings, power lines/poles and trees.
Breaking down event evolution/timing for the local area, first of all, even before convection flared up it was already an unusual/noteworthy December weather day given unseasonable warmth/humidity being pumped into the area on strong south winds. By late morning-early afternoon, southerly gusts were commonly 35-50 MPH as temperatures soared into the mid-60s to low-70s F (setting new Dec. 15th records in Grand Island/Hastings), accompanied by dewpoints surging at least briefly into the 50s F (mainly near/east of Highway 281). This set the stage for severe convection/tornadoes during the early-mid afternoon, as the squall line that eventually impacted all but a few far western local counties raced through South Central NE at an incredible average forward motion of 65-75 MPH. The squall line, which was still in its infant stages as it entered Harlan County out of Kansas shortly before 1 p.m., rapidly intensified/expanded in scope while reaching the Highway 281 corridor by 2 p.m., and then in the blink of an eye had all-but-exited the extreme eastern fringes of the local area (Highway 81 counties) by 3 p.m....wrapping up a brief-but-wild two hours of weather. As for the nine confirmed South Central NE tornadoes, they all occurred between 1:27-2:43 p.m. and had at-times-intermittent path lengths between 7-15 miles. The tornadoes concentrated within counties mainly situated between the Highway 92 and Highway 6 corridors, touching down as far west as eastern Kearney/Franklin counties and as far east-northeast as Hamilton/Polk counties. The circulations were firmly embedded within the aforementioned squall line, making these quasi linear convective system (QLCS) tornadoes with often-intermittent damage paths. As is typical of such tornadoes, there was little in the way of clear cut photographic/video evidence, with the main exception consisting of a more classic looking photo of an EF-1 near Marquette. Although specific details regarding each of the nine tornadoes can be found in their respective event narratives, the vast majority of damage occurred to irrigation pivots, power poles/lines and a handful of outbuildings/grain bins, including a few fairly large metal outbuildings that were partially or completely demolished within only a few miles of communities such as Hastings, Marquette and Polk. Fortunately, no homes suffered major damage, although a few sustained relatively minor roof/siding issues. And although there were no reported injuries, one family north of Hastings had a fairly close call as their sport utility vehicle had several windows blown out of it only about one minute after they arrived home and sought shelter. Although straight-line thunderstorm winds along the surging line took a publicity backseat to the tornadoes, there were dozens of reported measured/estimated gusts of at least 60-70 MPH, and a handful of measured gusts as high as 75-85 MPH, highlighted by 85 MPH at Central Nebraska Regional Airport (official) and unofficial mesonet gusts of 84 MPH near Shickley, 83 MPH near Davenport and 81 MPH near Oxford. As just a sampling of damage attributed to convective winds: a blown-over semi truck on Highway 6 near Hastings; an overturned pickup truck and trailer along I-80 near Grand Island; significant roof and siding damage to a brick building in downtown Giltner; a metal outbuilding largely destroyed near Fullerton; a carport lofted into power lines in Bruning. Lastly in the convective department, hail was a minimal issue for the vast majority of South Central Nebraska. However, stones up to golf ball size significantly damaged a home near Marquette, while slightly smaller, wind-driven hail up to quarter size was reported in the Grand Island and Hastings areas, including a report of considerable damage to siding, fences and shingles in the Lake Hastings area.
Turning to non-convective severe winds, for the majority of South Central Nebraska they peaked in intensity a few hours after the passage of the squall line (and also impacted those few far western counties that were spared by convection), ramping up initially from the southwest and eventually west-northwest behind a surging composite cold front/dryline. Generally speaking, roughly the southwestern half of the local area observed its strongest non-convective winds between 2-7 p.m., while the northeastern half of the area peaked more so 4-9 p.m. However, the entire area endured at least a few hours of sustained speeds commonly 30-45 MPH and sporadic gusts of 50-70 MPH, including official peak gusts of 73 MPH at Hastings and Ord airports, and unofficial peak mesonet gusts of 77 MPH near Glenvil, 76 MPH near Davenport and 75 MPH near Norman. Although these non-convective winds undoubtedly caused considerable minor damage and/or exacerbated damage already done by earlier convective winds, specific reports were actually quite limited. However, one unique highlight of these southwesterly-turning-westerly winds is that they shrouded much of the local area a under an eerie pall for a few hours during the mid-late afternoon...a combination of blowing dust (emanating off the western High Plains) and also smoke (from large wildfires in northern KS) that reduced visibility to under a mile in some spots. Fortunately, no wildfires were sparked within South Central NE itself, despite favorable conditions for large fire growth behind the dryline (especially in southwestern counties). The final severe-criteria gust of the evening (59 MPH) occurred in Nance County shortly after 7 p.m., and gusts eased down to only 30-40 MPH within most of South Central NE by 10 p.m.
The last weather element of this multi-faceted event (and ironically of least-overall impact for December) was snow, as far western/northwest portions of the local area observed roughly a one-hour period of wind-whipped snow between 3:30-5:30 p.m. as a weakening deformation zone on the backside of the system clipped parts of mainly Dawson, Sherman, Valley and far western Buffalo counties. Although total accumulations were mainly at-or-below one-half inch and there were no reports of significant travel impacts, the fact that this snow band prompted brief, greatly-reduced visibility reductions along Interstate 80 prompted the first-ever Snow Squall Warning issuance within South Central NE.
Examining the meteorology behind this event, this would have been considered a powerhouse setup for severe convection/high winds during the more typical spring season usually associated with this type of system, let alone in mid-December. In the mid-upper levels, not only was the parent, negatively-tilted shortwave trough notably intense as it slammed across the central United States, but it was also notably fast. At daybreak, its vorticity maximum was just passing by the Four Corners, but by mid-day it had already reached the NE/CO/KS border area and by sunset had advanced into far northeast NE. At the 500-millibar level, a stout jet streak of 100+ knots nosed into South Central NE from the south-southwest during the afternoon, while lower in the column a potent southerly low level jet (evident at 850 millibars) ramped up to 40-60 knots. At the surface, a vigorous low pressure center sliced across the heart of Nebraska from southwest-to-northeast during the afternoon, deepening to around 984 millibars along the way and driving a sharp dryline/cold frontal combo eastward through the area. As mentioned, surface dewpoints climbed into the 50s F across much of the area prior to convective initiation, fostering a corridor of mixed-layer CAPE up to 500-1000 J/kg. Although somewhat modest instability values by warmer-season standards, in this case it was more than enough to promote robust severe convection in the presence of extreme wind fields, with embedded QLCS tornadoes no surprise given 0-1 kilometer bulk shear around 40 knots and effective storm-relative helicity (SRH) around 200-300 m2/s2. In the wake of the squall line, the ensuing non-convective wind event corresponded to a zone of deep subsidence (likely associated with a sting jet) and a pronounced surface pressure gradient on the backside of the departing low, with a 16-millibar gradient noted across South Central NE at 6 p.m. (ranging from 988 mb at Columbus to 1004 mb at McCook).
Closing with some comments about official NWS forecasts leading up to this historic event, there was excellent awareness several days in advance regarding the likelihood of powerful non-convective winds both ahead of (southerlies) and behind (westerlies) the intense surface low pressure system. An area-wide High Wind Watch was issued early on the 13th (48-60 hours in advance) and was subsequently upgraded to a High Wind Warning early on the 14th. However, what was not as well anticipated (both at the local and national forecast level) was how great of a convective/tornado threat South Central NE would face, as the fast-tracking squall line ended up forming slightly earlier and several counties farther west than most model data suggested (especially 12+ hours out). As a result, there was a noticeable ramp-up of convective threat categories within South Central NE on Dec. 15th SPC Day 1 Outlooks, progressing from the initial 06Z outlook that barely brushed the far eastern fringes of the area with a Marginal Risk (level 1 of 5), to the 1630Z outlook that correctly shifted Slight (level 2) and Enhanced (level 3) categories westward into several counties along/east of Highway 281.
