 Learn more about SKYWARNTM!
We ask our SkyWarnTM Spotters to contact our office (via web form:Thunderstorms:Winter, or phone) when they experience any of the following things:
NEW WINTER CRITERIA!
- Snowfall (NEW CRITERIA!)
- When (new) snow accumulation reaches 3 inches
- When (new) snow accumulation reaches 6 inches
- Give a final report/total at the end of the storm (water equivalent if possible)
- 1 inch per hour or greater accumulation rates
- Ice (NEW CRITERIA!)
- Any occurrance, or accumulation, of freezing rain
- Accumulation of 1/4" or more of ice on trees/wires
- General Winter Reports (NEW!)
- When forecast winter precipitation differs significantly from observed (i.e. snowing with no snow in forecast, sleet...when only snow is forecast...)
- Any other significant weather occurrence/oddity (i.e. flooding due to snow melt/ice jam, damage from strong winds not associated with a thunderstorm)
- Tornadoes or funnel clouds (be very wary of look-alikes; watch for rotation)
- Wall clouds, especially if they are rotating
- Hail (Be specific with regard to size; DO NOT report MARBLE size, as it is too ambiguous) Report in inches or relate it to a coin. Penny (3/4") and larger is severe!

- Wind Gusts (40 mph or greater; specify whether estimated or recorded)
- large branches downed (specify diameter of branch)
- Trees/power lines downed
- Structural damage to buildings (roof, windows, etc.)
- Rainfall
