Wright Patterson Welcome History


Clark, Greene, Miami, Montgomery and Preble counties were all created in the early 1800s: Clark County in 1818, Greene County in 1803, Miami County in 1807, Montgomery County in 1803 and Preble County in 1808.

Clark County was named for George Rogers Clark, a hero of the American Revolution. It was originally part of Greene, Champaign and Madison counties. The county began to flourish during the 1830s, with the completion of the National Road through Ohio.

Greene County was named for Gen. Nathanael Greene, an officer in the Revolutionary War. In 1818, a small amount of territory was taken from Greene County to form Clark County. Greene County’s territory has remained the same since that time.

Miami County residents named the county in honor of the Miami Indians. Previously, the county had been part of Montgomery County. Montgomery County was named in honor of Richard Montgomery, an American Revolutionary War general killed in 1775 while attempting to capture Quebec City, Quebec. Montgomery County flourished during the 19th century. With the completion of the Miami and Erie Canal in 1829, Dayton was connected to Cincinnati.

Preble County was formed from portions of Butler and Montgomery counties. It is named for Edward Preble, a naval officer who fought in the American Revolutionary War and against the Barbary Pirates.

Weather and Climate

Wright Patterson Welcome Weather and Climate

67 degrees. The coldest month is January, with an average high of 36 degrees and an average low of 21 degrees. Dayton’s average yearly rainfall is about 41 inches.

Local Hazards

Every second counts in a disaster so planning and preparation can be lifesavers.

Ready Ohio is Ohio’s official emergency preparedness campaign managed by the Department of Homeland Security. The Ready Ohio campaign gives residents, communities, public safety professionals, businesses and schools valuable information and resources regarding a variety of emergency scenarios. The website provides information on creating an emergency plan and emergency kit, pet preparedness and disaster preparedness for seniors. For more information about disaster preparedness, visit www.ready.ohio.gov.

Another great resource for natural disaster and severe weather information is the Centers for Disease Control and Prevention website at www.cdc.gov/disasters. Here you can find information on how to prepare for various weather emergencies.

The following are considered significant hazards in Ohio.


Ohio doesn’t typically experience earthquakes on a large scale, but they do occur. In 2016, there were 10 earthquakes in Ohio. Besides the damage from the shaking, earthquakes can trigger landslides, surface fault ruptures and liquefaction, all of which can cause injury or property damage. Contact your local city or county government for information on how to be prepared where you live. More information and ideas on how to secure the contents of your home can be found by visiting www.ready.ohio.gov/ReadyForEarthquakes.stm.


Floods are the most common natural disaster in the United States. Even beyond coastal regions, flash floods, inland flooding and seasonal storms affect every region of the country, damaging homes and businesses. It is dangerous to underestimate the force and power of water.

During a flood watch or warning, gather your emergency supplies and stay tuned to local radio or TV stations for further weather information. If you are outdoors during a rainstorm, seek higher ground. Avoid walking through any floodwaters — even water 6 inches deep can sweep you off your feet. If you are driving, avoid flooded areas. The majority of deaths in floods occur when people drive through flooded areas. Roads concealed by water may not be intact. Water only a foot deep can displace a vehicle. If your vehicle stalls, leave it immediately and seek higher ground. Rapidly rising water can engulf a vehicle and sweep it away.

Sun Exposure

Some exposure to sunlight is good, even healthy, but too much can be dangerous. Broad-spectrum ultraviolet radiation, listed as a known carcinogen by the National Institute of Environmental Health Science, can cause blistering sunburns as well as long-term problems like skin cancer, cataracts and immune system suppression. Overexposure also causes wrinkling and premature aging of the skin.

Cloud cover reduces UV levels, but not completely. Depending on cloud cover thickness, you can still burn on a chilly, overcast day, so be prepared with sunglasses, sunscreen, long-sleeved garments, wide-brimmed hats and a parasol.


While more likely at certain times of the year, thunderstorms can happen anytime. A severe thunderstorm can knock out power; bring high winds, lightning, flash floods and hail; and spin into a twister in seconds. Pay attention to storm warnings. Remember the rule: “When thunder roars, head indoors.” The National Weather Service recommends following the 30/30 rule: People should seek shelter if the “flash-to-bang” delay — the length of time in seconds from the sight of the lightning flash to the arrival of its subsequent thunder — is 30 seconds or less, and remain under cover for 30 minutes after the final thunderclap.

For more information, visit www.ready.ohio.gov/ReadyForThunderAndLightning.stm.


Tornadoes can develop quickly, with minimal warning, so it is important to have a plan in place before they occur. If a tornado watch is issued, weather conditions favor the formation of tornadoes, such as during a severe thunderstorm. A tornado warning is issued when a tornado funnel is sighted or indicated by weather radar. You should take shelter immediately during a tornado warning.

For more information on tornado preparedness, go to https://www.ready.ohio.gov/ReadyForTornadoes.stm.

Winter Storms

Prepare for winter storms by assembling a disaster supply kit for your home and vehicle. Have your car winterized before the winter storm season arrives. Listen to weather forecasts and plan ahead.

When winter storms and blizzards hit, dangers include strong winds, blinding snow and frigid wind chills. Avoid unnecessary travel during storm watches and warnings and stay indoors.

Winter storms can also cause power outages. During a power outage, gather in a central room with an alternative heat source. Use fireplaces, wood stoves and other heaters only if they are properly vented to the outside. Never use an electric generator or a gas or charcoal grill indoors. The fumes are deadly. If you use a space heater, keep the heater away from any object that may catch fire (drapes, furniture or bedding) and never leave it unattended. Avoid letting pipes freeze and rupture by leaving faucets slightly open so they drip continuously.
