Evidence / storm surfaces
How Jefferson saw the hail — from two instruments
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.
Radar signature field NEXRAD's hail signatures for this storm: the spots the radar detected from above. A detection overhead is not the same thing as a confirmed stone below.
Only the NEXRAD radar-signature surface resolved for Jun 2, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.
The storm in context
Where Jun 2, 2026 sits in Jefferson's hail record.
This was Jefferson's 2nd recorded hail day, arriving 5 days after the May 28, 2026 storm. By severity it ranks 4th of the 4 storms we have logged here. Radar put the day's largest stone over Jefferson at 0" — radar-estimated size aloft.
The Jun 2, 2026 convective day was bigger than Jefferson: the same system put hail over 635 other tracked cities, 7 of them in Colorado. Nearest: Shawnee (9 miles northeast, up to 0"); Lake George (19 miles southeast, up to 0.75"); Woodland Park (35 miles southeast, up to 0.5").

Ground reports
What people on the ground reported
These are storm reports filed with the National Weather Service and released through the NOAA Storm Prediction Center — public-domain observations from spotters, the public, and NWS surveys. We quote each one exactly as filed.
For this storm over Jefferson, the NWS report log is empty — a common outcome, since ground reports only happen when someone witnesses the hail and takes the time to call it in. The detection record for the date lives in the radar maps above.
Below the severe threshold
What 0" hail means for Jefferson roofs.
Radar signals under three-quarters of an inch stay below the National Weather Service severe threshold and generally indicate lower roof risk. Older or already-worn materials can still show effects, but radar alone cannot determine whether a specific roof was damaged.
