Questions Thornton homeowners ask

When was the last hail storm in Thornton?

June 17, 2025. 1 inch hail was reported about 0.6 miles from Thornton on June 17, 2025. Hail that size (quarter) can bruise asphalt shingles and dent gutters, downspouts and air-conditioner fins; this is the size the National Weather Service calls severe.

How many storms has Thornton had since 2023?

10 storm days reached the National Weather Service's severe line in or within a mile of Thornton: 4 with heavy snow, 3 with hail, 2 with high wind, 1 with thunderstorm wind. Each one is listed on this page with its date and what was reported.

Does a storm in Thornton mean my roof is damaged?

No. It means the storm reached your area at a strength that can mark a roof, which is why insurers and roofers both look after one. Hail of an inch or more and gusts of 58 mph or more are the sizes that can leave damage you cannot see from the yard, so the next step is a look at the roof, not a decision.

How do you know a storm reached my street?

From the National Weather Service: its storm reports (hail sizes and wind speeds called in by trained spotters, emergency managers and weather stations), its warnings and damage surveys, and the radar hail estimates it publishes. The street check on this page reads the same records for one address.
