As we look ahead to a very warm week, let’s remember to pay attention to our children, pets, elderly parents. Not only is it important to watch after their well being at home, it’s critical when we’re out running errands. If you have to wear a face mask for a prolonged period, pay special attention to your body.

Let’s review how hot a car can get when you leave it parked in the heat. According to data provided by the National Weather Service…

The atmosphere and the windows of a car are relatively transparent to the suns shortwave radiation (yellow in figure below) and are warmed little. This shortwave energy, however, does heat objects it strikes. For example, a dark dashboard or seat can easily reach temperatures in the range of 180 to more than 200 degrees F. These objects (e.g., dashboard, steering wheel, childseat) heat the adjacent air by conduction and convection and also give off longwave radiation (red) which is very efficient at warming the air trapped inside a vehicle.

Weekend: Saturday low 70s and dry. Sunday chance of rain, upper 60s! Yes, this would make the 5th weekend in a row with measurable rain.

It is National Lightning Safety Awareness Week.

Though we are not the lightning capitol, we get our share of thunderstorms. For the record, according to NASA, the highest number of lightning flashes occur in the far eastern Democratic Republic of Congo, and Lake Maracaibo in northwestern Venezuela. For facts and stats see slideshow below.
