Monday fourth day of excessive heat warning

Johnson County has moved into day four of an excessive heat warning that is in effect until 7 p.m. Friday.

Expect temperatures in the upper 90's to nearly 105 degrees every day this week, with afternoon heat indices from 105 to 112 degrees. It appears the region will still be sweltering during the evening as well, with overnight lows only cooling down to the upper 70's and lower 80's, according to the National Weather Service.

Prolonged exposure to the dangerous heat could result in heat exhaustion, heat cramps and heat stroke. Remember to drink plenty of water and stay in an air conditioned building if possible. Many public buildings in Johnson County will be open for those trying to stay cool.


'Dangerously hot weather’ expected; excessive heat warning Friday to Tuesday

De Soto and all of northeast Kansas will spend another weekend sweating under temperatures so high as to cause the National Weather Service to issue an excessive heat warning.

According to the weather service, warm and moist air in combination with sunny skies will lead to high temperatures of about 100 degrees, with heat indices above 105 degrees through Tuesday. Accordingly, an excessive heat warning goes into effect at 1 p.m. Friday and will not expire until "at least" 7 p.m. on Tuesday.

The weather service urges everyone to be mindful of strenuous outdoor activity, and to reschedule being outside to early morning or late evening hours, when possible.

You should also check on family members and neighbors, especially the elderly. And remember not to leave pets without shelter or water.

For those of you wondering the difference between a heat watch and a heat warning, the NWS says that heat watches are issued when prolonged periods of high temperatures are expected. Heat warnings, however, are issued when the combination of high humidity and high temperature are expected to make it feel as though it is 110 degrees or hotter.


NWS warns: Weekend will be hot

The National Weather Service has issued an excessive heat watch for the area. The watch goes into effect Friday afternoon, and is slated to last until Monday evening.

Temperatures during the weekend heat watch could reach as high as 100 degrees. Factoring in humidity, heat indices will be between 105 and 110 degrees.

The NWS (and we) would like to remind everyone that exposure to these high temperatures and humidities can lead to heat exhaustion and heat stroke. Remember to drink plenty of water and to take rest breaks in the shade.

Counties affected by the watch include:











Excessive heat warning in effect until 8 p.m. Tuesday

The National Weather Service in Topeka has issued an excessive heat warning for Johnson County until 8 p.m. Tuesday.

It should be mostly sunny and hot all day with a high near 97 degrees and a heat index value as high as 105. There is a 30 percent chance of showers and thunderstorms, mainly after 4 p.m.


Ozone alert in effect today in metro KC

The prospect of unhealthy levels of smog today has prompted officials to issue an orange Ozone Alert for the entire metropolitan Kansas City area.

The alert was issued Sunday by the Mid-America Regional Council (MARC) Air Quality Program.

This alert indicates that an unhealthy level of ground-level ozone, also known as smog, is expected in the Kansas City region.

The two most important actions residents should take on Ozone Alert days are:

• Protect your health

Ozone pollution can cause a variety of problems in healthy adults, including chest pains, coughing, nausea, throat irritation and difficulty breathing. People who are sensitive to air pollution—children, seniors and people with breathing or heart problems—should limit their exposure to outdoor air between 10 a.m. and 7 p.m. Everyone should consider scheduling outdoor activities before 10 a.m. or after 7 p.m.

• Reduce pollution

More than half of all emissions that lead to ozone pollution is caused by doing yard work, driving, grilling and other everyday activities. Residents can help reduce pollution by carpooling, taking the bus, postponing mowing and postponing refueling vehicles. On Ozone Alert days, fares for regular bus routes are only 75 cents.

Emissions from vehicles, lawn and garden equipment and other sources react in heat and sunlight to form ozone pollution. Other environmental factors—such as warm, sunny weather, low wind speeds and lack of rain—increase the likelihood of poor air quality.


Excessive heat warning issued for Monday, through 8 p.m.

One day after topping 100 degrees for the first time in 2011, the National Weather Service expects more of the same and has issued a second excessive heat warning.

The warning is in effect until 8 p.m. Monday night. The heat advisory that had been in effect has been expired.

According to the weather services, heat indices are expected to be between 110 and 115. Prolonged exposure can lead to heat related illnesses.

Those in the area of the warning, which covers virtually all of northeast Kansas, are urged to stay hydrated and avoid outdoor activities. Remember to check on family and neighbors who may not be as able to take care of themselves and monitor pets as well.


Slight risk of severe weather across much of Kansas Wednesday

The National Weather Service has put De Soto and much of Kansas in a slight risk of severe weather.

According to the Storm Prediction Center, there is a risk of large hail and damaging remains with the remnants of the storm system that pushed across northern Kansas last night. The chance of storms remains throughout the day.

The slight risk area also includes the Topeka and Kansas City area, as well as the rest of Kansas except the extreme northeast and southwest corners.


Johnson County Libraries encourage use as cooling centers

With the temperature rising and no sign of relief until the weekend, the Johnson County Library system encourages the public to use the libraries as cooling centers.

  • 10 a.m.-6 p.m., Monday, Wednesday, Friday

Johnson County, along with the majority of northeast Kansas, is under a heat advisory until Saturday, July 2.


Cool Savings: Expert offers tips on air conditioning

Bruce Snead, K-State Research and Extension residential energy specialist, answers questions about holding down cooling costs this summer.

Q: What’s the best temperature to set my thermostat?

A: Pick a comfortable temperature. Be aware, however, that unnecessary cooling can be costly, as homeowners can save 1 to 3 percent of their cooling costs for each degree of higher setting on their thermostat.

Q: I’m not always home, but I want the house cool when I get there. What can I do?

A: Install a programmable thermostat to cool the home when needed, and reduce cooling when away from the home. In Kansas, customers of Westar are encouraged to consider a WattSaver Program offering a free programmable thermostat to improve energy efficiency and reduce cooling costs.

Q: Servicing my air conditioner is costly. Is it worth the money?

A: There is a cost to a service call, but a savings as well, if a routine inspection reveals potential problems before a breakdown occurs. Regularly scheduled maintenance also helps to maintain the efficiency of the system and can prolong its length of service.

Q: What are some easy steps to take to save over the long term?

A: Indoors, keep blinds or other window coverings closed during the day. Outside, plant shade trees to shield a home from the sun; the trees will need time to grow, and, in the interim, plant vines on a trellis to shield windows from the sun.

Q: Any other advice?

A: Invest in a home energy audit to see if adding insulation, caulking, weather stripping, etc., will result in a savings. For more information, go online to to learn about a low-cost energy audit and loan program to improve energy efficiency.


Tornado watch issued for Johnson County until 10 p.m.

The National Weather Service's Storm Prediction Center in Norman, Okla., has issued a tornado watch for Johnson County until 10 p.m. this evening.

According to the weather service, there is a moderate risk of tornadoes and damaging winds, as well as a high risk of severe hail.

An area of unstable air is moving towards a wind shear, making it possible for thunderstorms to quickly turn into supercells, the NWS reports.

A tornado watch means conditions are favorable for the formation of tornadoes and severe thunderstorms, but none have been reported in this area at this time. Stay tuned to local media and the NOAA weather radios for updates on this potentially dangerous storm system.
