DANGEROUSLY HOT TEMPERATURES WILL OCCUR. THE COMBINATION OF HOT
TEMPERATURES AND HIGH HUMIDITY WILL COMBINE TO CREATE A DANGEROUS
SITUATION IN WHICH HEAT ILLNESSES ARE LIKELY. DRINK PLENTY OF
FLUIDS…STAY IN AN AIR-CONDITIONED ROOM…STAY OUT OF THE SUN…
AND CHECK UP ON RELATIVES AND NEIGHBORS.

Heat Grip Relaxes a Few Days

June 23, 2009 Eddie Leave a comment

PMBrief

(Tuesday, June 23, 2009) – Very high dew point temperatures (a measure of the amount of moisture in the air) and the hot air temperatures combined to push heat index values into the 110 category this afternoon. In North Jackson our high temperature was 96º with the highest heat index at 111º. McKellar-Sipes Regional Airport hit 97º today. Bemis topped out at 98º.

The frontal boundary mentioned in this mornings brief has almost pushed west to the MS River now. Thunderstorms have formed in the more humid air to the west of the boundary. This is well depicted on the satellite image above. Other isolated storms are noted on radar that could drift into or form around West TN. Most areas will remain dry.

Air that is drier and not as hot will settle in over the region for the next day or so and then the hot weather will take the stage again with dangerous heat index values returning by Friday. The next rain chance worth noting will begin Sunday.

Heat warnings and advisories will expire at 7 PM.

Front Coming in the “Back Door”

June 23, 2009 Eddie Leave a comment

 

AMBrief

 

(Tuesday, June 23, 2009) – Only a few passing clouds this morning at sunrise. Low temperatures in the 70s. At 6 AM, temperatures ranged from 70 at Savannah, Lexington and Paris to 77 at Dyersburg.

The high pressure ridge that has been directly over us has shifted a bit to the west and will do so a little more today and will allow a cold front to come in from the EAST! This is called a backdoor front since cold fronts usually come in from the west or northwest. This front will do two things: 1) allow for some pop-up thunderstorms this afternoon (chances at 20% that it will rain on your garden/lawn) and 2) will push the highest heat index values a little further west.

At 4 am, the boundary streached from Springfield, IL to Chattanooga, TN to Jacksonville, FL. One lone thundershower was near Evansville, IN which was along the boundary. The West TN counties in the heat advisory today are Lake, Dyer, Lauderdale, Tipton, Shelby and Fayette. It will be hot all over W.TN today. Highs will be back into the mid-upper 90s. So even if your county is NOT under a heat advisory, it will be hot enough to use caution especially between 10 am and 7 pm.

I’m not optimistic about any big-time relief the rest of the week. Drier air will work into the region, but that won’t curb the hot temperatures. It will lower risks associated with high heat index values so that advisories may not be necessary after today.

A/C & Water Activities Only Relief for the Week

June 22, 2009 Eddie Leave a comment

(Monday, June 22, 2009) – First full week of summer had a week of practice! Satellite images and surface reports at 7 am showing mainly clear skies and temperatures in the mid-upper 70s.

Local weather news continues to be dominated high pressure at the surface and aloft that is producing sweltering temperatures and humidiites. Heat advisories continue today with AMBriefonly very minor relief expected as the week wears on. Instead of mid and upper 90s we will see temperatures come down a bit as the upper ridge eases west and thus relaxing a bit its grip on us.

Hard pressed to find some rain chances before Friday and then only about a 20 percent chance. Its a week of summer fun by the lake or pool!

Hot Weather Into First of the Week; Heat Advisories Continue

1 PM Satellite Image

Highs in the mid and upper 90s across West TN today.  (97º here in N. Jackson with highest heat index recorded:  108º) Upper level high pressure centered over the Lower Mississippi Valley will continue to provide hot, humid weather with highs in the mid and upper 90s and heat index values over 105 degrees.  Thus the heat advisories will continue into the first of the week.  A reminder of heat safety measures courtesy of the Red Cross:

Beat the Heat with Red Cross Safety Tips

Monday, June 09, 2008 — As the sweltering summer heat sweeps the nation, the American Red Cross reminds everyone to take precautions against heat related incidents.  So many simple measures can be taken to significantly reduce the chance of getting heat exhaustion and heat stroke.  The Red Cross encourages drinking plenty of water and taking frequent breaks while working outside. Staying inside and avoiding strenuous activity is also recommended. 

According to the Centers for Disease Control and Prevention, approximately 400 Americans die each year due to summer’s sweltering heat. Furthermore, the National Weather Service asserts that excessive heat was the number one weather-related killer, causing more fatalities per year than floods, lightning, tornadoes, hurricanes, winter storms and extreme cold from 1994 to 2003. 

Everyone is at risk when temperatures rise above 90 degrees but the elderly and the very young are most susceptible to heat and heat-related illnesses. Heat-related illnesses can cause serious injury and even death if unattended. Signs of heat-related illnesses include nausea, dizziness, flushed or pale skin, heavy sweating and headaches. Victims of heat-related illness should be moved to a cool place, given cool water to drink and ice packs or cool wet cloths should be applied to the skin. If a victim refuses water, vomits or loses consciousness, call 9-1-1 or your local emergency number immediately.

Red Cross Heat Safety Tips:

 

  • Dress for the heat. Wear lightweight, light-colored clothing. Light colors will reflect away some of the sun’s energy. It is also a good idea to wear hats or to use an umbrella.
  • Drink water. Carry water or juice with you and drink continuously even if you do not feel thirsty. Avoid alcohol and caffeine, which dehydrate the body. Avoid using salt tablets unless directed to do so by a physician.
  • Eat small meals and eat more often. Avoid high-protein foods, which increase metabolic heat.
  • Slow down. Avoid strenuous activity. If you must do strenuous activity, do it during the coolest part of the day, which is usually in the morning between 4 and 7 a.m.
  • Stay indoors when possible. If air-conditioning is not available, stay on the lowest floor out of the sunshine.  Remember that electric fans do not cool, they simply circulate the air.
  • Be a good neighbor. During heat waves, check in on elderly residents in your neighborhood and those who do not have air conditioning.
  • Learn Red Cross first aid and CPR.

Know What These Heat-Related Terms Mean:

 

  • Heat cramps: Heat cramps are muscular pains and spasms due to heavy exertion. Although heat cramps are the least severe, they are an early signal that the body is having trouble with the heat.
  • Heat exhaustion: Heat exhaustion typically occurs when people exercise heavily or work in a hot, humid place where body fluids are lost through heavy sweating. Blood flow to the skin increases, causing blood flow to decrease to the vital organs. This results in a form of mild shock. If not treated, the victim may suffer heat stroke. Signals of heat exhaustion include cool, moist, pale flushed or red skin; heavy sweating; headache; nausea or vomiting; dizziness; and exhaustion. Body temperature will be near normal.
  • Heat stroke: Also known as sunstroke, heat stroke is life-threatening. The victim’s temperature control system, which produces sweating to cool the body, stops working. The body temperature can rise so high that brain damage and death may result if the body is not cooled quickly. Signals include hot, red and dry skin; changes in consciousness; rapid, weak pulse; and rapid, shallow breathing. Body temperature can be very high—sometimes as high as 1050 F.


General Care for Heat Emergencies:

 

  • Heat cramps or heat exhaustion: Get the person to a cooler place and have him or her rest in a comfortable position. If the person is fully awake and alert, give half a glass of cool water every 15 minutes. Do not let him or her drink too quickly. Do not give liquids that contain alcohol or caffeine. Remove or loosen tight clothing and apply cool, wet cloths, such as towels or sheets. Call 9-1-1 or the local emergency number if the person refuses water, vomits or loses consciousness.
  • Heat stroke: Heat stroke is a life-threatening situation! Help is needed fast. Call 9-1-1 or your local emergency number. Move the person to a cooler place. Quickly cool the body. Immerse victim in a cool bath, or wrap wet sheets around the body and fan it. Watch for signals of breathing problems. Keep the person lying down and continue to cool the body any way you can. If the victim refuses water or is vomiting or there are changes in the level of consciousness, do not give anything to eat or drink.
