WW 215 TORNADO IA NE SD 121810Z - 130200Z
URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 215 NWS Storm Prediction Center Norman OK 110 PM CDT Fri May 12 2023 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Far Western Iowa Central and Eastern Nebraska South-Central South Dakota * Effective this Friday afternoon and evening from 110 PM until 900 PM CDT. * Primary threats include... A couple tornadoes possible Scattered large hail and isolated very large hail events to 2 inches in diameter likely Scattered damaging wind gusts to 70 mph possible SUMMARY...Thunderstorms are expected to develop across portions of the central Plains this afternoon. Environmental conditions will support strong to severe thunderstorms, including some supercells capable of tornadoes and very large hail (i.e. greater than 2 inches in diameter). The tornado watch area is approximately along and 70 statute miles north and south of a line from 40 miles north northwest of Ainsworth NE to 40 miles northeast of Shenandoah IA.

MD 0776 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR EASTERN KANSAS
Mesoscale Discussion 0776 NWS Storm Prediction Center Norman OK 0357 PM CDT Fri May 12 2023 Areas affected...Eastern Kansas Concerning...Severe potential...Watch possible Valid 122057Z - 122300Z Probability of Watch Issuance...40 percent SUMMARY...Isolated, but intense, thunderstorms are possible across eastern Kansas within the next few hours. Storm coverage remains uncertain, but trends will be monitored for possible watch issuance. DISCUSSION...Visible satellite imagery across eastern KS shows a deepening trend of cumulus congestus along a dryline over the past hour. A 19 UTC sounding from TOP shows residual capping in place over the region, and forcing for ascent along this portion of the boundary remains somewhat weaker given some displacement from stronger synoptic ascent to the north. Additional daytime heating over the next couple of hours should allow temperatures to warm further into the mid 80s, combined with adequate residence time within the dryline circulation based on the TOP wind profile, may be sufficient for isolated convection. While the number of storms remains uncertain, the environment is characterized by strong buoyancy (MLCAPE near 3000 J/kg) and favorable deep-layer shear for organized supercells with an attendant risk of large hail and severe winds (and perhaps a tornado closer to the I-70 corridor where low-level flow is more backed to the southeast compared to locations further south). Trends will continue to be monitored for thunderstorm initiation, and a watch may be needed. ..Moore/Mosier.. 05/12/2023 ...Please see www.spc.noaa.gov for graphic product...

MD 0775 CONCERNING TORNADO WATCH 215... FOR NORTHEAST NEBRASKA TO NORTHEAST KANSAS
Mesoscale Discussion 0775 NWS Storm Prediction Center Norman OK 0323 PM CDT Fri May 12 2023 Areas affected...Northeast Nebraska to northeast Kansas Concerning...Tornado Watch 215... Valid 122023Z - 122230Z The severe weather threat for Tornado Watch 215 continues. SUMMARY...The severe threat across WW 215 will continue for the next several hours. The tornado threat will likely be maximized in the near-term across northeast Nebraska, while the severe threat is expected to increase across eastern Nebraska to northeast Kansas over the next couple of hours as storms mature. DISCUSSION...Over the past 1-2 hours, regional reflectivity/velocity imagery has shown several organized splitting supercells developing along and ahead of a northward migrating dryline. Splitting supercells have been observed within the arcing band of convection, with the right moving cells exhibiting strong mesocyclones capable of producing tornadoes (with a few tornadoes already reported). This is likely due to enhanced low-level SRH along a subtle confluence axis noted in recent surface observations. The storms associated with recent tornado reports appear to be residing along this boundary as they move to the northwest. This will maintain the tornado threat for the next hour or so. Beyond this time frame, increasing storm interactions casts some uncertainty into the longevity of any one cell. Further the southeast across eastern NE into far northeast KS, cell development is noted along the dryline where richer boundary-layer moisture is supporting MLCAPE values in excess of 1500-3000 J/kg. Additionally, VWP observations from KOAX, supported by recent 19 UTC soundings from OAX and TOP, suggest low-level SRH is on the order of 100-150 m2/s2, which should support an increasing tornado threat over the next couple of hours as cells mature, but prior to gradual upscale growth this evening. An additional watch may be needed in the near-term for parts of northeast KS to address this concern. ..Moore.. 05/12/2023 ...Please see www.spc.noaa.gov for graphic product...

SPC 2000Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0308 PM CDT Fri May 12 2023 Valid 122000Z - 131200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS FROM NORTHEAST NE/FAR SOUTHEAST SD INTO EAST-CENTRAL NE/WESTERN IA... ...SUMMARY... Strong to severe thunderstorms are expected to continue into this evening across northeast Nebraska and vicinity, where a few tornadoes, very large hail and wind damage will be possible. Strong to severe storms are also expected to develop from eastern Kansas southward to Texas later this afternoon, with a potential for damaging winds and large hail. ...20Z Update... A 10% tornado area has been added from north-central into east-central NE. An arc of several potentially tornadic storms is ongoing across central/northern NE, in association with an occluded cyclone centered near North Platte. Favorable low-level shear within an environment characterized by enhanced low-level CAPE and ambient vorticity near the surface cyclone will continue to support the potential a few tornadoes. Severe potential is expected to expand into parts of southeast NE and western IA later this afternoon, with all severe hazards possible. Farther south, a substantial increase in thunderstorm coverage is expected later this afternoon and evening from OK into much of TX, along/east of a weak surface boundary. While deep-layer shear is marginal at best, large buoyancy will support a threat of hail and severe gusts with outflow-driven cells/clusters through the evening and potentially into the overnight hours. See the previous discussion below for more information. ..Dean.. 05/12/2023 .PREV DISCUSSION... /ISSUED 1119 AM CDT Fri May 12 2023/ ...Eastern NE into the Mid MO Valley ... Morning satellite imagery and surface observations show a stacked cyclone centered over western KS/NE border vicinity. Occluded surface low associated with this cyclone is forecast to further occlude as it lifts northward throughout the day. Warm sector to the north and east of the surface low is characterized by temperatures and dewpoints in the mid to upper 60s. Modest heating within this moist low-level environment is expected to result in moderate to strong buoyancy by the early afternoon. Thunderstorm development is then anticipated as a cold front associated with the low pushes into the region during the early afternoon. Ample buoyancy will exist for storms to persist as the move northward/northeastward off the boundary. Vertical shear is sufficient for storm organization, but is not overly strong, owing to the weakening mid-level flow. This weakening is somewhat countered by the modest southeasterly low-level flow, and resulting low-level veering with height. However, the overall wind profile leads to some questions regarding overall supercell coverage, with a somewhat clustered storm mode currently anticipated. Even so, a few supercells capable of all severe hazards, including very large hail and tornadoes, are still possible. Additionally, ambient low-level vorticity should enhance the tornado potential along and north of the front. ...Eastern KS into southern OK/northwest TX... Ample low-level moisture exists east of a Pacific front/dryline extending from the surface low over the western KS/NE border vicinity southward through central KS and then back southwestward through northwest TX. This dryline may make modest eastward progress across KS today (and even less across OK) before then retreating back westward later this evening. Large-scale forcing for ascent is nebulous, but mesoscale ascent along this dryline combined with a destabilized airmass with moderate to strong buoyancy is expected to result in thunderstorm development. Modest deep-layer flow and resultant modest shear suggests a potential outflow-dominant storm mode, but a few transient supercell structures could still occur. Strong gusts and large hail are the primary severe threats. ...West TX into the TX Hill Country... Current satellite imagery shows a weak shortwave trough moving through northern Mexico. This shortwave is expected to continue northeastward into Trans-Pecos, interacting with the warm, moist, and strongly buoyant air mass across the region. Widespread thunderstorm development is anticipated, with an outflow-dominant, multicellular mode favored. Some amalgamation along outflows is expected, with resulting clusters also capable of damaging gusts. Storm interactions may also result in updrafts strong enough to produce large hail. ...Portions of the Southeast... Weak convective cluster continues to gradually push southeastward from the Mid-South into MS. 12Z JAN sounding sampled over 7 deg C per km from 700 to 500 mb and recent observations show upper 60s to low 70s dewpoints ahead of the cluster across MS. These conditions, coupled with diurnal heating, is expected to result in strong buoyancy this afternoon. Redevelopment along this outflow could result in a few stronger storms capable of water-loaded downbursts. Read more

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0135 PM CDT Fri May 12 2023 Valid 131200Z - 141200Z ...NO CRITICAL AREAS... The previous forecast (see below) remains on track, with no changes or additions made. ..Squitieri.. 05/12/2023 .PREV DISCUSSION... /ISSUED 0143 AM CDT Fri May 12 2023/ ...Synopsis... A broad midlevel low will be centered over portions of the Great Basin. On the backside of this feature, enhanced northerly midlevel flow will overspread a relatively warm/dry airmass over the western CONUS. While locally dry/breezy conditions are possible (primarily focused along/east of the Cascades), these conditions will be too marginal/localized for any highlights. ...Please see www.spc.noaa.gov/fire for graphic product...

SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1230 PM CDT Fri May 12 2023 Valid 131200Z - 141200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM CENTRAL/EASTERN IA INTO NORTHWEST IL...AND ACROSS PARTS OF SOUTH TX... ...SUMMARY... Scattered severe storms are possible across parts of Iowa and Illinois, with more isolated storms into the lower Ohio Valley. Scattered severe storms are also possible across parts of South Texas, with an isolated risk across a broader portion of the southern Plains. ...IA/IL into the lower OH Valley... A weakening deep-layer cyclone is forecast to move slowly eastward from the mid MO Valley across northern IA on Saturday. The evolution of convection during the D1/Friday period will influence the position of important surface features, but in general, a warm front is expected to extend east-southeastward from central IA into northwest IL, while a surface trough will extend south of the warm front and weakening cyclone. Midlevel lapse rates will be rather weak, but relatively rich low-level moisture will support moderate buoyancy by afternoon, and scattered thunderstorm development is possible near the surface low and along the warm front. Favorably veering wind profiles will support the potential for a few supercells initially, posing a threat of hail, locally damaging wind, and possibly a couple of tornadoes with any cells near/just north of the warm front, where low-level shear/SRH will be modestly enhanced. One or more clusters may eventually evolve and move southeastward into the evening, posing a continued threat of isolated hail and damaging wind that may spread into the lower OH Valley. ...South TX and vicinity... An MCS may be ongoing across parts of south/central TX at the start of the forecast period Saturday morning. Depending on the intensity/organization of the system overnight leading into D2/Saturday, some threat for severe wind/hail will be possible in the morning. The severe risk is expected to spread southeastward toward the lower TX coast with time, though guidance varies regarding whether this occurs early in the day, or if the morning MCS decays and allows for redevelopment during the afternoon. Regardless, rich low-level moisture will support moderate to strong buoyancy in the preconvective environment, which in turn will support a threat of severe wind/hail until storms move offshore. ...OK into north TX... An MCV is forecast to move northward across the TX South Plains/Panhandle during the day on Saturday. Scattered thunderstorms are expected east of the MCV track. Instability may remain rather modest due to weak midlevel lapse rates, but diurnal heating and modest deep-layer shear (effective shear generally 20-30 kt) may support a few strong storms during the afternoon, with a threat of isolated hail, locally damaging gusts, and perhaps a brief tornado. ..Dean.. 05/12/2023 Read more

The Centennial Water and Sanitation service areas have been in a stage one restriction since July 2022. Stage one restrictions limit outdoor irrigation to twice weekly. The area remained in moderate drought due to below normal snowpack and ongoing drought. The aim is to reduce outdoor water use by 15% to 20%. Highlands Ranch Herald (Englewood, Colo.), May 11, 2023 Stage 1 drought restrictions took effect for parts of Douglas County for the first time in 20 years. Centennial Water and Sanitation serves customers in Highlands Ranch, Solstice and northern Douglas County. Residents were asked to limit outdoor watering to two days per week. McLellan, South Platte and Chatfield reservoirs, where Centennial Water stores its water, was at 37% capacity. Storage was about 6,368 acre-feet of water, compared to the normal storage of about 10,000 acre-feet. 9News (Denver, Colo.), July 21, 2022
