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

Mom finds out daughter with autism was sexually abused at DC school week after it happened
CONTENT WARNING: This story contains content that may be uncomfortable to some readers. Discretion is advised.
WASHINGTON (7News) — A mother said she learned her 13-year-old daughter was sexually abused in a D.C. school when a detective contacted her a week after it happened. She said the school never notified her.
7News sat down with the mother on Friday, while her daughter was being evaluated and interviewed by detectives. We’re not sharing the mom’s identity to protect her daughter.

The mom said she got a call Sunday night, “regarding my daughter and a sexual assault that happened at school involving my daughter last Monday.”
However, it didn’t come from the place or people she said she counted on.
“I never got a phone call from the school, an email, a text, nothing to say,” said the mom. Nothing happened until a week later.
That’s when a detective called and told her what happened.
“She was forced to give oral sex to a student in school,” said the mom.
Her 13-year-old daughter is disabled, autistic, and has challenges communicating.
The mom said she was sending her daughter to school without knowing what happened.
“I noticed a little behavior, emotional changes,” said the mom. “When I got that call now, it makes sense to, you know, what you because of what she had experienced at school and to come home and she didn’t say anything or no one had called me and just like it breaks my heart.”
7News obtained a copy of the police report, which confirms the youth investigative branch is investigating what happened to her daughter as sexual abuse. It shows that a Kelly Miller Middle School social worker reported it to the Metropolitan Police Department (MPD) last week.
“I just hope that I can be able to get her back on the right track. From all the trauma, on top of trauma,” said the mom. “To be able to grow and not have to hold that in the back of her head that she experienced in school, which should have been her safe place.”
7News started reaching out to DCPS just after 12:30 p.m. to ask if the students suspected of the abuse have been removed from the school, and why parents wouldn’t have been notified about the incident. They did not get back to us until after our first report aired. They did not answer either question. They provided the following statement.
A district spokesperson provided this statement:
At DC Public Schools (DCPS), student safety and wellbeing are paramount, and the district treats any allegation of sexual misconduct with the utmost seriousness. DCPS will continue to cooperate with law enforcement as this matter is investigated.
In accordance with the Family Educational Rights and Privacy Act (FERPA) and our obligation to maintain student confidentiality, we are unable to provide comment on individual student cases.
If you or someone you know is a victim of sexual assault or abuse, the National Sexual Assault Hotline can be accessed by calling 1-800-656-4673.

For our faculty who use Canvas, we have created this guidance, and we will continue adding resources tomorrow. Please stay in touch with your students as we adapt to this evolving situation.
Prince George’s County Schools
There has been a cybersecurity incident involving Canvas, our Learning Management System.
Instructure, the parent company of Canvas, notified us of a global cybersecurity incident affecting 275 million users across numerous educational institutions. We have been informed that PGCPS was one of the many impacted organizations. While personal information including names, emails and Student IDs was impacted, NO sensitive information, such as dates of birth, passwords, financial information, was involved. PGCPS does not store that type of sensitive information or parent information in Canvas.
We are using this as an opportunity to reinforce the importance of exercising caution when communicating by email and remaining vigilant regarding suspicious messages, spam, phishing attempts, or other potentially fraudulent communications.
We will continue to monitor the situation and remain in close communication with Instructure.
Anne Arundel County Public Schools
Due to the ongoing issues with the Canvas Learning Management System (LMS), AACPS will operate schools on Friday, May 8, 2026, without the use of the LMS. The Virtual Academy will also remain open with altered instructional delivery that will also not use the LMS. Further instructions will be communicated from the school principal. The latest information regarding the breach and the status of school district operations can be found at www.aacps.org/canvasbreach.
