| 2026-06-22 | SIDEBURN, VA | 90 | Severe | A severe thunderstorm produced a strong downburst one mile|northwest of Burke VA with peak winds estimated 90 MPH. While|other minor scattered tree damage was noted outside of the|microburst in the general area, the microburst affected the|communities around Lake Royal. Significant concentrated damage|began along Zion Road between the cross streets of Guinea Drive|and Hillard Lake Road. Tree damage continued along Bridgewood|Drive and Falmead Road before reaching Lake Royal. Through this|area, many, though not all, of the trees were snapped midway,|uprooted, or had large branches snapped off. Trees fell onto cars,|powerlines, roads, and homes with substantial damage. Damage was|unidirectionally pushed to the east northeast in the direction of|storm movement.||As the microburst crossed Lake Royal, the lack of trees and|roughness allowed the winds to accelerate and then blast the|townhomes on the east shore. Several townhomes on that row facing|the lake had significant portions of their roofs lifted off. Winds|were estimated to have peaked at 90 MPH.||On the south side of the lake along Guinea Drive, trees were|snapped onto the road and powerlines. A business park building was|noted to have some damage due to the roof being slightly lifted|temporarily.||Significant tree damage continued to the community on the east|side of Lake Royal with similar tree damage along Lakepoint Drive|west of Guinea Road. Trees and branches were again snapped onto|cars and homes, and townhome fences were pushed down on many|properties. East of Guinea Road, winds lessened and tree damage|became isolated. One further point of note was Burke Road near|Peppercorn Drive where a few trees were downed, one onto a bus|stand and street light.||Throughout the survey, damage was pushed to the northeast in the|direction of storm movement. NWS Doppler Weather Radar KLWX in|Sterling, VA, as well as FAA Terminal Doppler Radars from TDCA|and TADW, displayed thunderstorm downburst signatures at the Burke|location at the time, with no evidence of rotation indicating the|storm being tornadic. Severe straight line thunderstorm downburst|wind gusts can sometimes produce damage equivalent to damage from|EF0 and EF1 tornadoes.||Severe thunderstorms can produce wind gusts equal to EF0 and EF1|tornadoes.||The National Weather Service would like to thanks Fairfax County|Department of Emergency Management and Security for their|assistance. |

The most recent quarter-size-or-larger hail storm recorded by NOAA within 25 miles of Ashburn was on July 28, 2026. HailCheck refreshes from the NOAA Storm Events database daily, so newer events appear here as they are reported.
Ashburn averages roughly 15 reported hail events per year within a 25-mile radius. Significant storms (quarter-size or larger) account for 72 of the 76 events recorded over the last five years.
The largest documented hail near Ashburn in the last five years was egg-sized. Most Ashburn-area hail falls in the marble-to-quarter range, with destructive storms (egg-size or larger) appearing roughly once every few years.
Most homeowners insurance policies in VA cover hail damage to roofs, siding, and gutters under the dwelling and other-structures coverage. Coverage typically requires the damage to be tied to a verifiable storm date — which is where the NOAA hail history above (and a HAAG-style test square validation) becomes important for the claim file.
Use the HailCheck address search to enter any street address in or near Ashburn. HailCheck returns every NOAA hail event within a configurable radius, along with severity bands, dates, and storm narratives for Pro members.
If your property in or near Ashburn took on hail during one of the storms above, the standard process for documenting damage is a 10×10 foot test square inspection. A HAAG-trained reviewer counts impact indicators — granule displacement, mat fractures, and bruising — within the marked square and produces a PASS or FAIL document for the claim file.
HailCheck offers a $99 photo-based HAAG-style test square validation. You submit photos from the field, our reviewer evaluates the impact indicators and cross-references the NOAA storm dates listed above, and a written PASS/FAIL determination is returned within one business day. We do not send anyone to the roof — the validation is built around the photos you submit.
Learn About $99 HAAG-Style ValidationAshburn sits east of the traditional hail alley, where hail events are less frequent than the central plains but tend to be associated with strong squall lines and tropical systems. Local roof systems are less commonly hardened for hail, which can mean even moderate impacts produce claim-worthy damage.
