Wet Weather Continues Across Parts of the Northeastern States; Unsettled Weather Pattern Returning to the Pacific Northwest

A series of storms will bring rain and gusty winds to the Northeast U.S. for the next couple of days. The rain could combine with melting snow to produce flooding on main stem rivers, especially in northern New England. Unsettled weather will return to portions of the Northwest this weekend and continue for several days. Rain, some high elevation snow, and gusty winds will be possible. Read More >

Thomas Tornado

This tornado began 4.5 miles south of Thomas, and touched down intermittently as it moved east-southeast. The tornado was wrapped in rain for much of its existence. It appeared to weaken/dissipate as it crossed Highway 54 about 6.5 miles south-southeast of Thomas, where several power poles were snapped.

Geary Tornado

WSR-88D Twin Lakes, OK (KTLX) Radar Reflectivity Image at 7:32 PM CDT on May 29, 2004The second tornado of this storm began 3 miles northeast of American Horse Lake, or 9 miles west-northwest of Geary. This tornado also was obscured by rain for much of its life cycle, but was documented at close range by Doppler on Wheels (DOW) research scientists. The center of the tornadic circulation initially moved east-southeast, approaching American Horse Road around 6:24 PM CST, about 6 to 7 miles west-northwest of Geary, and then turned to the east-northeast.

Damage occurred over a wide swath to the right of the center of circulation, and was the combined result of the tornado and damaging winds from the very strong mesocyclone within which it was embedded. A peak instantaneous wind gust was measured by the DOW team at 81 m/s (157 knots, or 181 mph) at a height of 6.5 meters above ground level (AGL) in the mesocyclone circulation just north of Geary at 6:36 PM CST.

Four miles northwest of Geary, several smaller-scale vortices developed around the initial circulation center - one of which became the dominant circulation and formed about a half a mile south of the original center at 6:32 PM CST. Due to continuity of the parent mesocyclone circulation and the continuous damage path, these circulation centers are considered to be sub-vortices within the same tornado, and not separate tornadoes. The newly-formed circulation center moved slightly south of due east, and crossed U. S. Highways 270/281 at 6:37 PM CST, two miles north-northwest of Geary. The tornado crossed into Canadian County at 6:38 PM CST, 11.8 miles west-northwest of Calumet.

The tornado caused widespread tree damage with trees downed or uprooted across the area. Several barns were also damaged or destroyed in Blaine County. A house sustained some roof damage and power lines were downed in the area. A stock trailer was found rolled and farm machinery damaged. An old church one mile north of Geary also lost its roof.

The tornado, 2.5 north of Geary in Blaine County, crossed into Canadian County at 6:38 PM CST. Damage remained confined to the right side of the track of the circulation center. The tornado and the parent mesocyclone then turned to the northeast, inflicting F1 and low-F2 damage to several rural homes northeast of Geary. Seven miles northeast of Geary, the storm’s center of circulation turned back to the east at 6:52 PM CST, paralleling 220th Street (EW91 Road) for about 2 miles. It then turned to the northeast at 7:02 PM CST and eventually to the north by 7:08 PM CST. The tornado was wrapped in rain during its entire latter stages, and therefore was not visible. Doppler on Wheels (DOW) data indicate that the tornadic circulation crossed into Kingfisher County 11 miles west of Okarche. One farmstead, approximately 5-6 miles northeast of Geary, received heavy damage with the 100-year-old farmhouse sustaining substantial damage and several outbuildings and barns destroyed.

Data from the Doppler on Wheels (DOW) research scientists indicate that the tornadic circulation, 9.1 miles north-northwest of Calumet in Blaine County, crossed into Kingfisher County 11 miles west of Okarche at 7:11 PM CST. The forward speed slowed as the parent mesocyclone occluded. The tornado then turned west, then south, and finally dissipated at 7:15 PM CST, two miles east of the Blaine/Canadian/Kingfisher county junction. No damage was reported with this portion of the tornado.

Calumet #1 Tornado

This anti-cyclonic tornado formed from a new lowering that first developed west-northwest of Calumet. Unlike the earlier tornadoes, this one was not wrapped in rain and was documented visually by numerous spotters as well as the Doppler On Wheels (DOW). The tornadic circulation first formed at 7:02 PM CST about 2 miles north-northwest of Calumet, based on DOW data, but spotters observed only a funnel cloud until debris was spotted at 7:04 PM CST, 2 miles north of Calumet.

The tornado tracked generally east near EW95 Road, with occasional jogs to the northeast and southeast. It ended 4 to 5 miles northeast of Calumet at 7:14 PM CST. This tornado was visible mainly as a debris cloud on the ground; the condensation funnel reached the ground only briefly at 7:04 PM CST and again at 7:10 PM CST, otherwise it either remained aloft or was non-existent. The tornado also had multiple vortices briefly.

Two permanent homes received damage. One home towards the beginning of the tornado sustained minor roof damage with shingles blown off. Another home had an enclosure, which was built over the pool, destroyed. A nearby manufactured home also showed damage to its siding, roof, and windows. Damage was estimated at low end to middle F1.

Calumet #2 Tornado

This tornado, also anti-cyclonic, formed about 1 mile northwest of the previous tornado (4.5 miles east-northeast of Calumet) shortly after the latter dissipated. It touched down intermittently as it moved east-southeast, lifting 4 miles northwest of Concho at 720 PM CST after forming a very brief, needle-like condensation funnel seen by spotters and caught on video by local media. Damage was reported by spotters at a location 3 miles north and 4 miles east of Calumet.

Concho Tornado

This brief tornado was observed at close range by spotters 2 miles northwest of Concho. It likely originated from the same parent circulation that produced the previous two anti-cyclonic tornadoes near Calumet and west-northwest of Concho, but was likely a separate event. No damage was reported.

6 05/29/2004 1945-1947 1 50 F1 0 0 Canadian 6.5 W - 5.5 W Piedmont

Piedmont Tornado

Most of the damage in and around Piedmont appeared to be the result of strong straight-line winds - both inflow into the storm and strong winds within the mesocyclone. But local media showed video of and storm chasers observed a condensation funnel about 5 to 6 miles west of Piedmont. The tornado damaged a barn and downed several electric poles before crossing Northwest Highway near Banner Road. The tornado damaged several more barns before lifting 5.5 miles west of Piedmont.

7 05/29/2004 2004-2010 4.6 100 F2 0 0 Oklahoma 10.3 WNW Edmond - 7.1 NW Edmond (just N of Council/NW 206 - just E of Portland/Sorghum Mill)

Deer Creek Tornado

Sporadic F1 to low-end F2 damage occurred in the Deer Creek area, from Council Road between 206th and 220th Streets, east-northeast to near Highway 74 (Portland Ave.) and Sorghum Mill Road. As with earlier tornadoes, much of the damage in this area may have been the result of strong straight-line winds, although the concentration and severity of damage in this area suggests a probable tornadic spin up.

In the Deer Creek area, 135 homes sustained minor damage, with 7 incurring major damage, and another 7 homes were destroyed. Six mobile homes were damaged. Three were reported to have minor damage, while three others sustained major damage. Two businesses were also destroyed. The Deer Creek/Edmond public school received damage along with the First Baptist Church which was heavily damaged.

8 05/29/2004 2101-2103 0.3 50 F1 0 0 Logan 5 SSE Meridian

Meridian #1 Tornado

This nighttime tornado formed in rural areas 1 mile east of Indian Meridian Road and 2.5 miles north of the Oklahoma-Logan County line, or 5 miles south-southeast of Meridian, causing a small but concentrated area of tree and power line damage. Several large trees, with trunk diameters of 1 to 2 feet, were uprooted or snapped off near the base. Large tree limbs were snapped off from numerous other trees in the area. The damage was confined to mostly open country. No structural damage was found.

9 05/29/2004 2117-2125 4 100 F0 0 0 Logan 5 SE Meridian - 6 E Meridian

Meridian #2 Tornado

This tornado was described by spotters as having a large funnel and as a possible "wedge" tornado, but no damage was reported (although power flashes were observed). The estimated track, based on spotters and National Severe Storms Laboratory (NSSL) rotation track maps from the Twin Lakes radar, began 5 miles southeast of Meridian and continued northeast across rural areas, ending just inside the Logan/Lincoln County line at 9:25 PM CST, 6 miles east of Meridian. The parent mesocyclone occluded shortly thereafter, with a new one forming to the southeast.

10 05/29/2004 2127-2132 2.5 300 F1 0 0 Lincoln 3.5 WSW - 1 SW Carney

Carney Tornado

NSSL rotation track maps from the Twin Lakes, OK WSR-88D radar (KTLX) suggest that this was the first tornado from a new mesocyclone that formed southeast of the one that produced the two tornadoes near Meridian in Logan County. This tornado began 3.5 miles west-southwest of Carney in Lincoln County and tracked generally east along Hamner Park Road for 2.5 miles, ending about a mile SW of Carney. The tornado was described by spotters as being quite large. Eyewitness accounts and damage patterns indicate that it was likely a multiple-vortex tornado, but straight-line winds likely contributed to the damage.

Numerous large trees were snapped at the trunk or lost large branches. Several outbuildings and trailers were heavily damaged or destroyed. A 20 foot livestock trailer was rolled about 150 yards to the northeast. Impact marks indicate that the trailer bounced over two barbed-wire fences without damaging the fences. A riding lawn mower also was carried east about 50 yards over two chain-link fences with no significant damage to the fences. There were several permanent homes in the damage path, but all received minimal damage that was limited mostly to shingles, window frames, and impalement from wind-driven debris. Maximum path width was about 300 yards along Hamner Park Road about 2.5 miles west-southwest of Carney. Damage in this area was rated high-end F1.

Note: The last 6 tornadoes during the event occurred in the NWS Tulsa county warning area in Creek, Wagoner, and Mayes Counties.
11 05/29/2004 2218-2233 7.5 700 F3 0 0 Creek 6.2 WNW - 4.9 NNE Depew

Depew #1 Tornado

A tornado moved from the west-northwest of Depew to the north-northeast of Depew in Creek County. At its strongest it produced F3 damage. The F3 rating was based on a 20-foot section of a concrete anchored iron pipe cattle gate being removed from the ground and displaced 30 feet. The gate was anchored by 3 posts. All of the posts were set in 24 inches of concrete. Tornado #12 formed near and just after this tornado dissipated.

Depew #2 Tornado

This tornado formed near and just after tornado #11 dissipated near Depew in Creek County. The two tornadoes formed a nearly continuous damage path. The damage produced by the two tornadoes in western Creek County included 5 mobile homes destroyed, 2 houses destroyed, and 4 houses with significant roof damage. Tornado #12 and traveled mainly through open territory, but some of the structural damage that was mentioned previously occurred along its path.

13 05/29/2004 2312-2326 5.4 200 F1 0 0 Creek 3.6 W - 2.8 NE Kellyville

Kellyville Tornado

This tornado traveled to the west and north of Kellyville in Creek County, producing F1 damage to mainly trees and power poles.
