'Run-of-the-mill storms' sparked by afternoon heat
Posted May 27, 2014
Raleigh, N.C. — A line of thunderstorms fired up from the west and crossed the Triangle Tuesday afternoon.
"The chance for severe storms is slight," said WRAL Chief Meteorologist Greg Fishel, "but many of us could see these regular, old, run-of-the-mill thunderstorm this evening."
Some pea-sized hail and wind gusts of up to 40 mph was reported in Chatham County, but most areas just saw solid, steady rain.
Warm, moist air boosted temperatures and humidity over central and eastern North Carolina on Tuesday, marking the beginning of an unsettled pattern that will linger until a cold front passes through the area on Thursday.
Scattered showers and thunderstorms are possible during the late afternoon and evening over the next three days. The chance for showers builds with the heat of the day and dissipates after nightfall. The story will be similar on Wednesday, when storms could begin to fire after lunchtime.
"We won't see any widespread rain Tuesday or Wednesday, and our severe threat is relatively low, but we could see afternoon thunderstorms pop up pretty much anywhere during the middle of the week," said WRAL meteorologist Elizabeth Gardner. "You will also notice the increase in our dew points, which will make it feel much more like summer during the afternoon."
The best chance for precipitation will come on Thursday, when a front will push through the area from north to south. Daytime highs will top out only in the 80s thanks to the front, and cooler, drier air will arrive behind it.
"We will still have a chance for showers on Friday, but beautiful weather is going to return for the weekend," Gardner said. "We will see highs in the upper 70s to low 80s both Saturday and Sunday, and overnight lows will be crisp."
