Out With The Old...

Over the past couple weeks, you have probably noticed our new Storm Center and weather graphics. Although things have improved significantly as we continue to modernize our TV station, I couldn't help but be somewhat sentimental as the engineers dismantled the old set. Here are some photos and video:



Heat Index This Weekend

As a strong ridge of high pressure remains over the eastern U.S. this weekend, highs will climb into the upper-80's and low-90's, as detailed in the previous blog entry. Winds will be from the southwest at the surface this weekend, allowing for the return of some moisture into the Commonwealth. Moisture and heat combine to produce the heat index value. This "temperature" is a value based on the air temperature and the dew point temperature. It measures what the temperature will feel like to your body when you are in the shade. Yes, in the SHADE. Not in the sun. When you're outdoors in the sunlight, you can tack on about another ten degrees on top of the heat index value for what it will feel like to your body. In addition, the higher the humidity, the harder it is for the human body to effectively cool the skin quickly by sweating. On Saturday in Central Virginia, the heat index will be around 90 degrees, but by Sunday, heat indices will rise into the mid-90's in the shade. Add ten degrees for standing in the sun, and you've got an apparent temperature of 100 degrees. That falls into the "Extreme Caution" category for high risk people (kids, the elderly, and anyone with chronic conditions). But anyone spending extended time outdoors can still experience these symptoms.

You can calculate your heat index here.
In addition to the heat index, as you enjoy the warm temperatures this weekend outdoors, remember the UV Index will be High to Very High.

Be safe and enjoy the warmth this weekend!
