ROUGH WEATHER: Cooldown coming after unusual humidity
Cooldown coming after unusual humidity
Hot, sticky and uncomfortably heavy heat crawled in today with persistent thunderstorms creating unusually high humidity for June, according to the National Weather Service in State College.
The weighted and lingering heat Sunday made worse by humidity around 58 percent may seem mild compared to today’s oppressive humidity.
High temperatures in the upper 70s will seem much hotter with a humidity level of about 76 percent, meteorologist Craig Evanego said.
“There’s nearly a 100 percent chance of showers and severe thunderstorms,” he said. “It’s going to be humid and there will probably be some downpours with that.”
The Lycoming County 911 Center announced over dispatch at 6 p.m. Sunday that the National Weather Service had issued a severe thunderstorm warning.
A little over 2 1/2 hours later, the first signs of a powerful storm — very dark clouds and distant lightning — rapidly moved closer and hit Williamsport with heavy rain at 8:30 p.m.
Storms today are expected to linger all day and drop an average of half an inch of rain in most places across the county, Evanego said. But, some localized spots caught under the thick clouds of the storm could receive over an inch.
The storm should taper off tonight as temperatures drop to the lower 60s.
Chances of showers will continue Tuesday, but not with the same certainty as today’s storm, Evanego said.
“It will be partly to mostly sunny with a high around 80 degrees,” he said. “Once it clears back up, you’re looking at lows in the low 60s overnight.”
Tuesday begins what Evanego said is cooling down for the rest of the business week.
Wednesday is expected to be mostly sunny with highs in the upper 70s, with clouds coming in overnight to make for a pleasant mid-50-degree night.
Thursday will be 10 degrees hotter with a 40 percent chance of thunderstorms in the evening.
Temperatures Thursday night into Friday are expected to be in the mid- to upper 60s.
Chances of thunderstorms continue Friday, accompanying cloudy skies and a warmer day in the mid-80s.
“Basically, what the area is seeing is a bit of a cool-off with those storms after (to)day,” Evanego said.
After the dip, temperatures will rise once again — continuing with the summer heat until its late summer peak.
