TORNADO UPDATE: NWS details damage in Clark, Greene counties

GREENE COUNTY TORNADO

Five sheep were killed in the EF1 tornado that touched down near Xenia on Tuesday afternoon, National Weather Service investigators said. 

The finding was included in the public statement based on their survey of damage to more than 25 properties as the result of the tornado, with 95-mph winds, that hit about 4:45 p.m. 

NWS investigators said the first confirmed damage area was in the 1000 block of Ludlow Road in Beavercreek Twp., where there was wall damage and roof was taken off a large barn and a collapsed silo occurred at a second barn. There was roof and chimney on a residence on the property. Numerous hardwood and softwood trees were damaged as well.

Several properties farther east along Ludlow Road were damaged. The most significant damage occurred in the 800 block, where more than 30 percent of one home’s roof was torn off and multiple windows were broken. 

Additional, significant barn and tree damage occurred on the property. 

In the 700 to 500 block of Ludlow, several homes had roof damage. Barns had significant damage.

The tornado continued east, in the 2400 North Block of U.S. 68. Minor damage was done to a home, mainly siding and roof damage as well as a collapsed chimney and a destroyed fence. A large camper was rolled over and the roof was lifted off a brick outbuilding. 

Farther east along Clifton Road, in the 700 and 800 block, barns and homes had roof and porch damage. Significant roof and siding damage was present on the residences of two homes in the 2400 block of Clifton Road.

“A sheep farm in this area did experience the loss of five sheep,” weather service investigators said.

The northern most extent of confirmed tornado damage was along state Route 72 and Clifton Road. They reported widespread tree and roof damage along Wilberforce-Clifton Road and 72, south of Clifton, all in the same north-northeast direction. 

“While the wind damage was significant in this area, estimated to be as high as 80 mph, this damage was more consistent with straight line wind damage," investigators said.

CLARK COUNTY TORNADO

National Weather Service investigators released details about the EF1 tornado that touched down 3 miles west and northwest of Selma and southwest of South Charleston, in Clark County. 

The tornado hit during a three-minute period (4:56 to 4:59 p.m.), cutting a path of 4.3 miles and packing 90-mph winds. There were no injuries. 

Investigators said the first visual sign of tornadic damage was observed on Cortsville Road, where a barn was destroyed and a large hardwood tree was knocked down.

“Damage continued to the east-northeast, particularly at the McDorman Farm on Selma Pike where multiple buildings were damaged. A significant portion of the roof of one building was lifted off and blown into an adjacent field. On another building, multiple sides had siding removed and sustained some roof damage. Exterior walls on multiple sides of a large barn were also damaged. 

“It is possible that the tornado briefly lifted beyond this property, although additional tornadic damage was observed as far east as Clifton Road. Shutters were removed and lifted from multiple sides of a two-story home. One tree was also downed nearby. 

“An eyewitness report confirmed the presence of a tornado in this vicinity. The tornado is believed to have ended shortly after as no additional damage was observed further east along Clifton Road and within South Charleston.”

“It has been determined that the tornadic damage in this vicinity is separate and independent from the tornadic damage further southwest in parts of Greene County, Ohio,” NWS officials said in their Public Information Statement. 

INITIAL REPORT (April 4)

National Weather Service investigators plan to conduct storm damage surveys this morning to confirm whether a tornado touched down Tuesday in northern Greene and possibly into southeastern Clark counties.

“Based on radar evidence and damage reported, it is believed that a tornado was responsible for damage in northern Greene County, possibly extending into southeastern Clark County,” the National Weather Service said in a statement.

The NWS will look at radar evidence, and consider photos, videos and storm reports from the public and first responders to determine what caused the damage. 

“They look at how the damage is thrown about when they are on the survey site,” said Storm Center 7 Meteorologist Kirstie Zontini. “If trees are snapped in random directions, a tornado likely caused the damage. If trees or damage looked to be knocked over in one direction, then straight line winds are more likely to blame.”

No injuries were reported.

Xenia and Beavercreek townships, Greene County

Severe storms Tuesday afternoon caused significant damage in Xenia Twp. and Beavercreek Twp. There was significant damage to trees, barns and other buildings from Ludlow Road to Clifton Road in the area of U.S. 68 and Ohio 235.

“It was southwest of the village,” said Chris Clark, Madison Twp. Fire and EMS Chief. “It was moving east. There was obvious and significant rotation in it, however I couldn’t see the base because of the vantage point. I can’t say it was on the ground but it was a rather large funnel cloud.”

Reports of hail, damaging winds amid tornado warning

Another system moves in today, this time bringing the potential for severe thunderstorms, said Storm Center 7 Meteorologist Kirstie Zontini.

>> Live Doppler 7 Interactive Radar 

Tornado Warning is issued until 4:30 p.m. for Montgomery and Preble counties.

Flash Flood Warning is in effect until 7 p.m. Shelby, Preble, Champaign, Logan,  Darke, Montgomery and Miami counties.

The Storm Prediction Center has most of the Miami Valley under an Enhanced Risk for severe storms. The best ingredients for strong and severe storms looks to come together along and ahead of a cold front that approaches tonight. Impacts from this system will be felt from the morning and into Tuesday night.

>> Severe Weather: Slight vs Enhanced risk

COMMUTE IMPACTS 

Tuesday eveningStorms are expected to redevelop late in the afternoon and through the evening mainly from 5 to 11 p.m.

These storms have a high chance of becoming severe. The main threat is damaging winds and flash flooding but there is the possibility of an isolated tornado or two to develop in a strong storm or line of storms.

Larger sized hail is a low threat for the day.

>> Severe weather alerts sign-up 

Drivers should check the forecast and Live Doppler 7 Radar for a look at the afternoon development. Storms will become more widespread toward the end of the drive.

>> WHIO Weather App

Drivers should watch for flash flooding, reduced visibility and severe storms during the evening hours. The biggest impacts outside of flooding will be damaging winds. Some storms could also produce hail and an isolated tornado can't be ruled out.

>> Impacting your drive: Strong wind, heavy rain

Once the cold front passes at night, the rain will taper off. The Wednesday morning drive should be quiet, but a few flurries are possible if it gets cold enough. 

Slick spots possible as temperatures drop overnight

Skies will clear with temperatures dropping into the lower 20s overnight, Storm Center 7 Chief Meteorologist Eric Elwell said. Some refreeze of slushy areas likely, which could lead to some slick spots.

Blizzard of 1978: Today marks daily snowfall record anniversary

If you think we’ve had a rough winter so far, at least it’s not a repeat of 1978.

On Jan. 26, the storm dropped over a foot of snow; this date still holds the record for the most snow in Dayton in a 24-hour period, according to Dayton Daily News archives.

The 40th anniversary of the Blizzard of 1978 is this week. The blizzard lasted three days, from Jan. 25 until Jan. 27, 1978.

The National Guard was called in to help deliver supplies and rescue those stuck in the snow. Interstate 75 was closed for four days, air traffic was halted at the airport, and RTA and the postal servic both halted service.

Winter storm timeline: When the storm will hit where you live

Don't let the spring-like weather fool you Thursday. A winter storm is still going to impact the Miami Valley Friday. 

Here’s the latest projected timing of the storm:

FRIDAY: Rain showers will impact most of the area before 8 a.m.. A transition to a wintry mix of sleet and freezing rain will develop between 7 and 10 a.m. in communities like Celina, Wapakoneta, Sidney and Greenville. The cold air will transition the central Miami Valley to a wintry mix from 12 p.m. into the early afternoon in the Dayton area. Everyone then has the chance to see scattered snow for the evening drive. The chance for a light glaze of ice then snow will keep the roads slick Friday into Saturday morning. 

>> RELATED: Rainy and warm today; Winter Storm Watch issued Friday through Saturday morning

SATURDAY: Active snow will end very quickly overnight. Most of the impacts Saturday will come from refreeze and blowing/drifting snow. Saturday will be much colder so anything wet or untreated could stay snowy or icy. Gusts around 30MPH will be possible. Temperatures overnight will drop into the single digits!

>> RELATED: Friday storm brings threat for icing before transition to snow

The combination of a wintry mix and snow (likely two to four inches w/isolated higher amounts) will make this system impactful.

Could a coming storm system turn into a ‘weather bomb’?

UPDATE (Nov 15) 2:30 p.m.

The first of two major storm systems to impact the Miami Valley is crossing the area this evening bringing with it showers and breezy conditions.

We are still tracking a stronger system which will impact our area Friday into Saturday. There have been some changes in how the late week storm is set to evolve. Earlier model runs from a few days ago showed this storm system rapidly strengthening and pushing across the Miami Valley late on Friday. 

That timing would have increased the risk for severe storms in our area late Friday and produced a significant threat for high winds. While the threat for strong winds still appears to be on the table, the timing has changed based on the latest model runs.

RELATED: See more trending stories on WHIO.com

Now, the storm system is forecast to move into the Ohio Valley early Saturday morning which will lower the threat for any severe storms. It also appears the storm system will not quite “bomb out” as it moves across the Great Lakes, although it will still intensify rapidly as it moves into the region. It now appears the storm system will not meet the definition of a “bombogenesis” which would mean the storm system would need to strengthen 1 millibar per hour for 24 hours.

That being said, there will still be a strong low-level jet stream that sets up with and just behind the storm system. As the storm system moves into the region late Friday, gusty winds will pick up to near or over 25 mph. As the cold front crosses early Saturday morning, wind gusts of over 40mph will be possible.

As cold air ushers in on Saturday morning, wind gusts could jump to between 40 to 50mph briefly before diminishing some Saturday afternoon and evening.

It will remain blustery through the weekend with temperatures falling from the 50s into the 30s Saturday and holding in the 30s on Sunday.

There will also be the chance for some scattered flurries or snow showers late Saturday night into Sunday, especially north of I-70. 

FIRST REPORT

As the seasons begin to change, the clash of warm and cold air masses fuel big storms, and we’ve certainly been a witness to that this month.

November is certainly known in history to produce some doozies. Just this past weekend, we passed the anniversary of the Veteran’s Day tornado outbreak that killed 36 people, including four in Ohio, in 2002. It was also the 42-year anniversary of a severe Great Lakes storm in 1975 that sank the Edmund Fitzgerald, killing all 29 on board.

A little more than a week ago, another massive storm produced 17 tornadoes in Ohio alone, with more in Indiana. Now, if the forecast models are correct, another major storm looks to impact the Miami Valley by the end of this week.

» READ MORE: National Weather Service confirms 17 tornado touchdowns in Ohio

Since last weekend, our long-range models have been showing the potential for another intense storm system to develop across the Northern and Central Plains late this week. The storm system is then forecast to begin “bombogenesis” as it sweeps into the Upper Midwest and Great Lakes. Bombogenesis refers to a rapidly intensifying area of low pressure.

To be classified as a weather bomb, the central pressure of an intensifying storm system must drop at least 24 millibars within 24 hours. Such storm systems are known to produce very strong, and in some cases near hurricane-force, winds. These types of systems are quite common near New England in the winter when Nor-Easters produce massive amounts of snow and blizzard conditions up the East Coast.

Sometimes these power storm systems can form near or over the Great Lakes and are aided by the relatively warm waters of the lakes. Late this week, we may get to witness what one of these intense storm systems looks — and feels — like.

At this point, it is too early to know if severe winds will be felt across the Miami Valley, but the potential exists for wind gusts to exceed 50 mph by late Friday and perhaps into Saturday. With such wind speeds, some power outages could be possible and should be planned for. If you have any loose items still outside, you’ll want to secure those before you go to bed Thursday night.

The greatest impact from the high winds will likely be closer to the Great Lakes themselves, not to mention on the Great Lakes where waves could grow to over 10 to 15 feet (or perhaps higher). Also, if you have early Thanksgiving Day travel plans, some flights could be impacted by this storm beginning late Thursday and through the weekend.

One other important note, if you have already started decorating for the holidays, or are planning to start later this week or even into the weekend, you may either want to make sure everything is secure or just hold off until the weekend after Thanksgiving. Otherwise, your Santa Claus may just take flight after all, along with the rest of your decorations.

He said many farms and turkey barns were destroyed. Farmers in the area are bringing out their equipment to help their neighbors in need, Grey said.

Celina Mayor Jeff Hazel said Grand Lake and Havemann roads in Celina also remain shut.

Power is restored to about 90 percent of the city. A total of 40 businesses are without power.

EARLIER REPORT

A storm survey is scheduled for Monday morning and will reveal more details about the severe storms that made their way through Wabash and Celina.

The survey will focus on supercell thunderstorms that moved through the county, according to the weather service.

Late Sunday, Celina Mayor Jeffrey Hazel declared a State of Emergency for the city.

Hurricane Nate downgraded to tropical storm, continues path on land

UPDATE @ 5:10 p.m. (Oct. 8)

Tropical Storm Nate continues to move north through as tropical storm and surge warnings for Southeast Louisiana and South Mississippi were canceled Sunday morning.

Natenever reached the Category 2 level forecasters expected, according to the National Weather Service, and began weakening overnight.

Social media posts from those living in parts of Louisiana, Alabama and Mississippi showed flooding and storm surges, but nothing near the destruction originally expected.

While the storm lost strength quickly, the National Weather Service reports Nate earned the distinction of the fastest moving Hurricane the Gulf of Mexico has ever seen.

UPDATE @ 8:15 p.m. (Oct. 7)

Hurricane Nate made landfall at the mouth of the Mississippi River as a Category 1 storm with winds of 85 mph.

The National Hurricane Center said that Nate is expected to make a second landfall along the Mississippi coast later tonight. Evacuations have been ordered along the central Gulf Coast.

UPDATE @ 6:20 p.m. (Oct. 7)

Hurricane Nate is expected to strengthen into a Category 2 hurricane at landfall tonight along the northern Gulf coast, the National Hurricane Center reported.

The storm’s top sustained winds were 90 mph as of earlier today.

Some oil and gas platforms in the Gulf of Mexico are being shut down as the hurricane churns toward the U.S. mainland, the Associated Press reported. About one-fifth of U.S. oil is produced in the Gulf.

UPDATE @ 11:50 p.m. (Oct. 6)

The National Hurricane Center reported late Friday that Nate is now a hurricane with maximum winds estimated at 75 mph.

UPDATE @ 1:10 p.m. (Oct. 6) 

Tropical Storm Nate is pulling away from the Honduras coastline and moving closer to the Yucatan Peninsula, according to the Friday update from the National Hurricane Center.

>> Fall color increases across the Miami Valley

Nate will bring heavy rain, damaging winds, storm surge and life threatening flash flooding to the Yucatan Peninsula region later today.

>> WHIO Interactive Radar

The storm will move north into the Gulf of Mexico early Saturday, then is expected to intensify to a hurricane before making landfall near New Orleans late Saturday or Sunday. Direct impacts will also be damaging winds, heavy rain, and significant storm surge.

The Miami Valley is expected see the remnants of this storm late Sunday night into Monday as it tracks to the south. The greatest threats locally will be heavy rain and gusty winds. 

EARLIER REPORT

A tropical depression that developed off the coast of Costa Rica has strengthened to become Tropical Storm Nate, said Storm Center 7 Meteorologist Kirstie Zontini.

The National Hurricane Center is expecting Nate to directly impact Nicaragua and Honduras today. Rain could exceed 20 inches in Nicaragua with as much as a foot possible near Honduras and eventually the Yucatan Peninsula. 

Tropical storm force winds extend 60 miles out from the center of the storm. Strengthening is possible as the storm moves north through the Gulf. Heavy rain, strong winds and dangerous storm surge will be possible up to the northern Gulf Coast, but specific placement and impacts are yet to be determined.

>> WHIO Interactive Radar

A long range track does show the left over moisture/the remnants from Nate bringing an increased chance for rain to the start of next week here in the Miami Valley. This could change as well.
