Cool Lightning, Hot Temps!July 17th, 2013 at 8:09 am by Jeremy Wheeler under Weather
There were some scattered showers and storms out there yesterday across the region. There was ample fuel for the storms as the temperatures climbed into the low/mid 90s and the humidity was rather high. There was also a weak pocket of energy (shortwave) moving through the region. This created some great shots of lightning. Here was one photo:
Colleen Umphlett took this from Grandy, North Carolina. It is a great shot of lightning under the moon. Very cool to see. The next shot is from Dan McLain. He got this shot of the lightning from Grandy, NC.
I love shots of lightning. Especially the ones where the shutter is left open. Anyway, the storms moved south of the region by the mid evening and then dissipated. Today we will still have a lot of heat and humidity, but the pocket of energy will not be there. So we may see an isolated shower or storm this afternoon, but there shouldn’t be much. A large area of high pressure has allowed the heat to build into the Midwest and Northeast over the last couple of days.
Temperatures today will rise to the mid 90s with some upper 90s inland. The dew points are still in the mid 70s. So that creates a heat index between 100-110. There were several cities yesterday that got up to that level. Highs for the next 3 days will be in the mid 90s. The heat index will again be between 100-110. These are the average high temps and heat indices for Hampton Roads over the next 4 days.
With a heat index over 100, heat illnesses can overcome a person through time. Here are is a site from NOAA with a little more explanation of what can happen: Heat illnesses.
