Heat index tops 100+

Heat indexes are going to reach 103 to106 degrees every day this week, as hot weather continues to plague the area.
National Weather Service Meteorologist Stephen Miller said the heat indexes are high because of the moisture in the air.
“Basically, we’re looking at highs in the mid-90s,” Miller said. “With the moisture we have around, it’s giving us heat indexes around 103 to 106 degrees every day through the rest of the week. It’s not enough for a heat advisory, but still, if you’re not cognizant of that and what to do, it still can cause problems.”
For the next three days, the high is expected to be 96 degrees. The temperature will drop down to 94 on Friday.
Miller said high pressure in the upper atmosphere causes the warmer temperatures to be prevalent.
“If you were to look at the upper levels in the atmosphere, say 10,000-15,000 feet up, there is a upper level of high pressure,” he said. “With that higher pressure, it forces air down. That’s leading to warmer temperatures.”
Miller said temperatures are hotter than the NWS’s 30-year seasonal average.
Unfortunately, a break in the hot weather isn’t going to come any time soon as the high pressure system is working its way east, Miller said.
“The problem with high pressure is that it tends to cut off the rain,” he said. “We need to have little pools of moisture working through, which give us a better chance of seeing rain.”
Miller said day-to-day, the chance of rain is between 20-30 percent for the rest of the week and into the weekend.
