Here’s why there was a downpour of large hail in the D.C. area on Monday


In a relatively uncommon occurrence for the region, a widespread downpour of large hail impacted parts of the District and Loudoun, Fairfax and Prince George’s counties Monday afternoon, as a severe thunderstorm storm raced east and southeast across the area. Readers captured numerous photos and videos of the hail, while three-dimensional radar imagery detailed a stunning view of the storm’s inner workings.

Dozens of severe-hail reports were logged by the National Weather Service. Hail that is about one inch in diameter, or roughly the size of a quarter or larger, is considered severe with the potential for damage. Hail as big as golf balls — which are 1.68 inches in diameter and more likely to leave dents in vehicles — was reported near Brambleton in southeast Loudoun County. Another storm also tossed large hailstones to the north, in Montgomery County.

Significant hail days are not terribly common around Washington, but when they happen, it is often during the spring before peak thunderstorm season arrives. This is because of the combination of strengthening spring sunshine, which creates strong currents of rising air in the lower atmosphere, and a lingering winter chill at the mid-levels, plus stronger jet stream winds. These factors allow spheres of ice to rapidly grow within bubbling clouds.

One striking aspect about yesterday’s “hailers” is that they developed over the D.C. region less than 24 hours after a similar widespread outbreak of severe hail-producing thunderstorms across north-central Pennsylvania on Sunday afternoon. It was the same weather front, but a different atmospheric disturbance along it, that triggered Monday’s hail.

The conditions that produced severe hail

The strong contrast between warm, relatively humid air in the lower atmosphere and cold, dry air higher up was a key factor in promoting the explosive thunderstorm growth that produced the large hail, but it wasn’t the only aspect.

A strong belt of winds from the west associated with the jet stream — a river of racing winds aloft — created a change in both the direction and speed of winds with height, or wind shear, which is typically required for powerful thunderstorms to develop.

The storm cells became powerful enough to keep growing hailstones suspended in the air, allowing them to swell to large sizes before falling to the ground. The longest-lived of the Monday storms qualified as supercells, at least at times. Supercells are characterized by strong and stable upward currents of air that persist for up to hours at a time. They are the types of storms most likely to produce severe hail and other hazards such as large tornadoes.

The swath of hail from southern Loudoun County to southern Prince George’s County seen on the image above was created by a single long-lived storm cell that is shown in the radar image below.

It had a very long track. The cell initiated northwest of Capon Bridge, W.Va., and pulsed up and down in severity. It appeared to have briefly generated hail over Winchester, Va., but then really got going over east-central Loudoun County, continuing in pulses through Fairfax County and southern D.C. and into Prince George’s County.

WTOP’s Dave Dildine reported cars suddenly parking under highway overpasses along the storm track, seeking refuge from the volley of large, potentially damaging hailstones. (As a brief aside, this is not advised for many reasons, including increased risk of accidents).

The radar image below, created with computer software that depicts the three-dimensional structure of the storm, shows intense precipitation lofted into freezing air above as the hail-generating supercell moved across Arlington. It is essentially a CT scan revealing the vertical structure of the storm, which towered to 45,000 feet, using microwave energy. This is shown in the figure below, as the hail-generating supercell was working across Arlington.

In this case, the mushroom-shaped inner core punches high up into the atmosphere like a fist. The air in that core was probably rising at speeds of 40 to 50 mph or faster.

The whole cloud is leaning, or tilting, because of the influence of the shearing winds. The white region below 10,000 feet represents the dense curtain of hail falling out of the storm. Few images so strikingly depict the impact of shearing winds on the development of a severe storm cell.

Photos and videos shared by readers

Impressive imagery and harrowing videos of the hail poured in via social media, especially on Facebook. One person said they had “never seen one this intense!”

Below are a few of the photos and videos we received. In the first photo, streaks of hail can be seen falling from the boiling mass of clouds amid the shining afternoon sun.

Draft DOJ report accuses DC police of manipulating crime data

Draft DOJ report accuses DC police of manipulating crime data


The Justice Department has notified D.C.’s Metropolitan Police Department that it completed its investigation into whether members of the department manipulated crime data to make crime rates appear lower, sources tell News4.

Multiple law enforcement sources familiar with the matter tell News4 that DOJ will release its findings as early as Monday.

A draft version of the report obtained by News4 describes members of the department as repeatedly downgrading and misclassifying crimes amid pressure to show progress.

MPD’s “official crime statistical reporting mechanism is likely unreliable and inaccurate due to misclassifications, errors, and/or purposefully downgraded classifications and reclassifications. A significant number of MPD reports are misclassified,” the draft report says.

Investigators spoke with more than 50 witnesses and reviewed thousands of police reports, the draft report says. Witnesses described a change under Chief of Police Pamela Smith.

“While witnesses cite misclassifications and purposely downgraded classifications of criminal offenses at MPD for years prior, there appears to have been a significant increase in pressure to reduce crime during Pamela Smith’s tenure as Chief of Police that some describe as coercive,” the draft report says.

The draft report faults a “coercive culture” at in-person crime briefings held twice a week.

“The individuals presenting are denigrated and humiliated in front of their peers. They are held responsible for whatever recent crime has occurred in their respective districts. For instance, if a district had a homicide and numerous ADWs over a weekend, Chief Smith would hold the Commander of that district personally responsible,” the draft report says.

Smith announced this week that she will step down from her position at the end of the month. News4 asked her on Monday if she is leaving because of the allegations and she said they didn’t play into her decision.

The DOJ review is one of two that were launched in relation to MPD crime stats, along with a separate investigation by the House Oversight Committee.

Both MPD and Mayor Muriel Bowser’s office have been given copies of the report. They did not immediately respond to inquiries by News4. The U.S. Attorney’s Office for D.C. also did not immediately respond.

News4 was first to report in July that the commander of MPD’s 3rd District was under investigation for allegedly manipulating crime statistics on his district. Cmdr. Michael Pulliam was placed on leave with pay and denied the allegations. The White House flagged the reporting.

“D.C. gave Fake Crime numbers in order to create a false illusion of safety. This is a very bad and dangerous thing to do, and they are under serious investigation for so doing!” President Donald Trump wrote on social media.

Trump has repeatedly questioned MPD crime statistics. He put News4’s reporting in the spotlight on Aug. 11, when he federalized the police department. He brought up the allegations against Pulliam at a news conference, and the White House linked to News4’s reporting in a press release titled “Yes, D.C. crime is out of control.”

A D.C. police commander is under investigation for allegedly making changes to crime statistics in his district. News4’s Paul Wagner reports the department confirmed he was placed on leave in mid-May.

D.C. Police Union Chairman Gregg Pemberton told NBC News’ Garrett Haake this summerthat he doubts the drop in crime is as large as D.C. officials are touting.

“There’s a, potentially, a drop from where we were in 2023. I think that there’s a possibility that crime has come down. But the department is reporting that in 2024, crime went down 35% — violent crime – and another 25% through August of this year. That is preposterous to suggest that cumulatively we’ve seen 60-plus percent drops in violent crime from where we were in ’23, because we’re out on the street. We know the calls we’re responding to,” he said.

In an exclusive interview on Aug. 11, News4 asked Bowser about the investigation.

“I think that what Paul’s reporting revealed is that the chief of police had concerns about one commander, investigated all seven districts and verified that the concern was with one person. So, we are completing that investigation and we don’t believe it implicates many cases,” she said.

D.C. Chief of Police Pamela Smith will step down at the end of the month after heading the department for less than three years. She spoke about her decision and whether tumult in D.C. including the federal law enforcement surge and community outrage over immigration enforcement played a role. News4’s Mark Segraves reports.

Senators Seek to Change Bill That Allows Military to Operate Just Like Before the DC Plane Crash

Senators Seek to Change Bill That Allows Military to Operate Just Like Before the DC Plane Crash


Senators from both parties pushed Thursday for changes to a massive defense bill after crash investigators and victims’ families warned the legislation would undo key safety reforms stemming from a collision between an airliner and Army helicopter over Washington, D.C., that killed 67 people.

The head of the National Transportation Safety Board investigating the crash, a group of the victims’ family members and senators on the Commerce Committee all said the bill the House advanced Wednesday would make America’s skies less safe. It would allow the military to operate essentially the same way as it did before the January crash, which was the deadliest in more than two decades, they said.

Democratic Sen. Maria Cantwell and Republican Committee Chairman Sen. Ted Cruz filed two amendments Thursday to strip out the worrisome helicopter safety provisions and replace them with a bill they introduced last summer to strengthen requirements, but it’s not clear if Republican leadership will allow the National Defense Authorization Act to be changed at this stage because that would delay its passage.

“We owe it to the families to put into law actual safety improvements, not give the Department of Defense bigger loopholes to exploit,” the senators said.

Right now, the bill includes exceptions that would allow military helicopters to fly through the crowded airspace around the nation’s capital without using a key system called ADS-B to broadcast their locations just like they did before the January collision. The Federal Aviation Administration began requiring that in March. NTSB Chairwoman Jennifer Homendy called the bill a “significant safety setback” that is inviting a repeat of that disaster.

“It represents an unacceptable risk to the flying public, to commercial and military aircraft, crews and to the residents in the region,” Homendy said. “It’s also an unthinkable dismissal of our investigation and of 67 families … who lost loved ones in a tragedy that was entirely preventable. This is shameful.”

Senate Majority Leader John Thune said he is looking into the concerns but thinks they can be addressed by quickly passing the aviation safety bill that Cruz and Cantwell proposed last summer.

“I think that would resolve the concerns that people have about that provision, and hoping — we’ll see if we can find a pathway forward to get that bill done,” said Thune, a South Dakota Republican.

The military used national security waivers before the crash to skirt FAA safety requirements on the grounds that they worried about the security risks of disclosing their helicopters’ locations. Tim and Sheri Lilley, whose son Sam was the first officer on the American Airlines jet, said this bill only adds “a window dressing fix that would continue to allow for the setting aside of requirements with nothing more than a cursory risk assessment.”

Homendy said it would be ridiculous to entrust the military with assessing the safety risks when they aren’t the experts, and neither the Army nor the FAA noticed 85 close calls around Ronald Reagan National Airport in the years before the crash. She said the military doesn’t know how to do that kind of risk assessment, adding that no one writing the bill bothered to consult the experts at the NTSB who do know.

The White House and military didn’t immediately respond Thursday to questions about these safety concerns. But earlier this week Trump made it clear that he wants to sign the National Defense Authorization Act because it advances a number of his priorities and provides a 3.8% pay raise for many military members.

The Senate is expected to take up the bill next week, and it appears unlikely that any final changes will be made. But Congress is leaving for a holiday break at the end of the week, and the defense bill is considered something that must pass by the end of the year.

Bill would rename former Black Lives Matter Plaza for slain conservative activist Charlie Kirk – WTOP News


A South Carolina Republican Congresswoman wants to rename a well-known stretch of 16th Street NW in D.C. after slain conservative activist Charlie Kirk.

A South Carolina Republican Congresswoman wants to rename a well-known stretch of 16th Street NW in D.C. after slain conservative activist Charlie Kirk.

Rep. Nancy Mace introduced legislation Wednesday to designate the area once known as “Black Lives Matter Plaza” as the “Charlie Kirk Freedom of Speech Plaza.” The proposal comes three months after Kirk was killed while speaking at a free-speech event at a Utah college.

Mace said the change would honor Kirk’s commitment to the First Amendment, calling him “a champion of free speech and a voice for millions of young Americans.” Her bill would require official signs to be placed in the plaza and updates made to federal maps and records.

In a statement, Mace contrasted the unrest that followed George Floyd’s killing in 2020, when the plaza was created, with the response to Kirk’s death, saying the earlier period was marked by “chaos and destruction,” while Kirk’s killing brought “prayer, peace and unity.”

She argued that after Floyd’s death, “America watched criminals burn cities while police officers were ordered to stand down,” adding that officers were “vilified and abandoned by leaders who should have supported them.”

But D.C. Del. Eleanor Holmes Norton pushed back, saying Congress should not override local control.

“D.C. deserves to decide what its own streets are named since over 700,000 people live in the city,” Norton wrote on X. “D.C. is not a blank slate for Congress to fill in as it pleases.”

The stretch of 16th Street was originally dedicated as Black Lives Matter Plaza in 2020 following nationwide protests over Floyd’s death. Earlier this year, the city removed the mural.
