(CNN) -- A potent storm system socked the Mid-Atlantic and as far north as New York on Thursday, lashing the region with damaging hail, strong winds and pelting rains.
At various points Thursday afternoon and evening, parts of Delaware, Virginia and Maryland were under tornado warnings tied to the system. There were reports of a few possible touchdowns, though thankfully no widespread damage or injuries.
Even without twisters, the storms did damage in other ways. Photos posted to Twitter from Wyomissing, Pennsylvania -- which is just outside of Reading -- showed some cars with smashed windshields thanks to large, powerful hail. Lt. Thomas D. Endy said two police cars in town aren't drivable, and three can go out only if absolutely necessary.
"It got really loud," said Heather Knaub, who was working at a department store in Berkshire Mall in Wyomissing when the hail started pounding down, eventually caving in some overhead glass windows. "... It looked like a white-out; hail was everywhere."
The National Weather Service documented scores of other such reports, including ones indicating hail the size of golf balls in locales from Hamden, New York, to Roxbury Mills, Maryland.
Central Virginia was particularly hard-hit, with Dominion Electric reporting about 14,000 customers without power around 9:15 p.m. due to hail and strong winds. This activity includes a "possible brief tornado" that may have hit in Prince George County, according to the weather service.
New York state got its share of bad weather as well, with the weather service tweeting that there was a tornado in Delanson. It later tweeted an image of house there that had been obliterated.
Much of upstate New York also had to deal with flooding concerns due to the combination of rain and hail. Some places north of Rome, New York, already got as much as 6 inches of rain, for instance.
The system caused temporary headaches for those traveling in and out of the region, with all traffic bound for New Jersey's Newark airport, New York's LaGuardia airport and Philadelphia's airport not allowed to take off until after 6:30 p.m.
And the Mid-Atlantic wasn't the only part of the country braving severe weather.
Hazardous weather outlooks were once in effect for huge swaths of the central and southwestern United States -- as far north as Montana and North Dakota, as far south as Arizona and Texas, and as far east as Tennessee.
The storms were also affecting areas in and around Denver, which was the site of several reported tornadoes on Wednesday.
Frontier Airlines tweeted that its call center there was evacuated due to the storm, around the same time Denver International Airport urged travelers to be on-guard for instructions if the situation takes a sudden turn for the worse.
