Recent Storm Days in Connecticut: Wind & Storm History
By StormAuditor Editorial Team · Published 2026-07-16 · Updated 2026-08-26
Based on public NOAA and National Weather Service records, published under StormAuditor's methodology and data-source standards. Radar-derived hail sizes are estimates unless attributed to a ground report.
Damage-threshold ranges in this article are general guidance synthesized from industry and federal research — IBHS building-performance research, NWS severe criteria, and product standards such as UL 2218 (hail impact resistance) and ASTM D3161/D7158 (shingle wind ratings). Actual performance depends on product rating, age, installation quality, exposure, and impact characteristics — thresholds describe when damage becomes possible, not when it occurs.
Connecticut experiences various severe weather events, from damaging winds to hail. StormAuditor provides detailed historical data to help you understand past storm activity in the Nutmeg State.
Recent Storm Activity in Connecticut
Connecticut sees plenty of severe weather. Winter storms get most of the attention. But the state also gets strong thunderstorms in the warmer months, with damaging wind and hail. These storms can damage property, so date-of-loss research needs accurate weather history. StormAuditor helps you look into past hail and wind at specific places in Connecticut.
What Makes a Storm Severe?
The National Weather Service (NWS) calls a thunderstorm severe when it produces any of these:
- hail 1.00 inch (quarter size) or larger,
- wind gusts of 58 mph (50 knots) or more, or
- a tornado.
"Significant severe" means hail 2.00 inches (hen-egg size) or larger, gusts of 75 mph or more, or an EF2+ tornado.
These levels help when you judge the risk to a property. Asphalt shingles often show functional damage from hail 1.00" to 1.25" across. On aged or poorly fastened roofs, shingles can lift with gusts of 46–57 mph, shingle loss is possible from 58 mph, and widespread roof-covering loss is possible from about 74 mph.
How StormAuditor Estimates Connecticut Storms
StormAuditor rebuilds past storms from public data and its own methods.
- Wind: Our SAWE-2, the Storm Auditor Wind Estimate method builds a wind field that agrees with nearby stations. It uses observed weather conditions, gusts measured at ASOS/AWOS stations, and NWS Local Storm Reports (LSRs). This lets us estimate the wind at your location.
- Hail: The Storm Auditor Hail Estimate v2 (SAHE-2) mainly uses radar hail swaths from MRMS: the Maximum Estimated Size of Hail (MESH), shown on Hail Explorer with a size estimate for each grid cell. We check these against SPC storm reports.
- Warnings: We add NOAA/NWS warning areas to show when a property was under a severe thunderstorm warning.
StormAuditor reports estimates, not measurements. Every value comes from public sources such as NOAA, NWS, and SPC reports.
Recent Notable Storm Days in Connecticut
Recent severe weather reports across Connecticut:
- July 5, 2026 — New London County — 65.0 mph thunderstorm wind gust in New London
- July 5, 2026 — Fairfield County — 64.0 mph thunderstorm wind gust in Rowayton
- July 5, 2026 — Fairfield County — 58.0 mph thunderstorm wind gust in Rowayton
- July 5, 2026 — Several counties, including New London, Middlesex, Hartford, and Fairfield — Multiple thunderstorm wind damage reports
Damaging wind is a steady concern in Connecticut. On that one day, gusts at or above the 58 mph severe level were seen in more than one place.
How to Research a Date of Loss in Connecticut
To look into a date of loss for property damage in Connecticut, use these tools:
- Property reports: Our Address Lookup tool builds a weather history report for your exact address. It shows hail, wind, and warnings at or near your location.
- Search by date: Our Date of Loss Weather Research page lets you explore conditions across the state or a region on one day.
- Weather on any date: For general conditions, such as peak gusts and rainfall, use our Weather on This Date tool.
These tools help owners, contractors, and adjusters see the weather behind a damage event.
Practical Guidance for Homeowners and Professionals
Weather history is key when you look at storm damage in Connecticut.
- Homeowners: Knowing the hail size or gust strength at your property helps you judge how likely damage is.
- Contractors and adjusters: The data gives an objective basis for claims and repairs.
- Everyone: StormAuditor gives weather estimates. Have a qualified inspector check the property for actual damage.
Roofing ratings matter too:
- UL 2218 Class 4 shingles give the highest hail protection. They resist impacts from 2.00" steel balls.
- For wind, shingles rated under ASTM D7158 (Class D/G/H) or ASTM D3161 (Class A/D/F) give different levels of uplift resistance.
Limitations
Weather history has limits:
- Radar hail estimates (MESH) can under-estimate wet hail. They can over-estimate in very strong reflectivity cores.
- Wind stations are reliable where they stand. They may miss small microbursts between stations.
- A property inside an NWS warning area was under a warning. That does not always mean it got the storm's peak.
- StormAuditor gives weather history and estimates. It cannot decide what caused damage, and it does not replace an on-site inspection. We do not give legal, insurance, or engineering advice.

FAQ
Q: How do I find storm history for my Connecticut address?
A: Enter your address in StormAuditor's Address Lookup tool. It builds a weather history report with hail, wind, and warnings for your location.
Q: When was the last major wind storm in Connecticut?
A: In recent data, July 5, 2026 brought strong wind across Connecticut. Measured gusts reached 65.0 mph in New London, and several counties reported wind damage.
Q: What size hail is considered severe in Connecticut?
A: The NWS calls hail severe at 1.00 inch (quarter size) or larger. Hail 2.00 inches (hen-egg size) or larger is significant severe, and damage becomes more likely.
Q: Can StormAuditor tell me if my roof was damaged?
A: StormAuditor gives weather estimates for your property, such as hail size and wind speed. These show the potential for damage. We cannot tell whether your roof was actually damaged. That takes an inspection by a qualified professional.
Q: What is a "date of loss" and why does it matter for weather research?
A: A date of loss is the day the damage happened. Knowing it lets you look at the exact hail and wind at your location that day. That matters for insurance claims and repair plans.
Q: What's the difference between a wind gust and sustained wind?
A: Sustained wind is the average speed over a set time, usually 1 or 2 minutes. A gust is a short, sudden burst that lasts a few seconds. For severe weather and property damage, gusts usually matter most.
