Radar tells you what the storm is doing; these tell you what it looks like. Pictures open at their source - ODOT and the Mesonet allow linking, not republishing.

No net is listed for NWS Glasgow yet. If you know the repeater and who runs it, suggest it - the state coordinator checks it and it shows up here and on the state hub. Never guess a frequency from memory; a wrong one during a warning is worse than none.

  • ·Wall cloud, especially a rotating one
  • ·Where it is relative to you, and which way it's moving
🧊 Hail
  • ·The largest stone, compared to a coin or ball (chart below)
  • ·1″ (quarter) is the severe threshold - smaller is still worth a report to most offices
  • ·How long it fell and whether it's covering the ground
💨 Wind
  • ·Measured gusts of 40 mph+; 58 mph is severe
  • ·Damage: trees down, limbs bigger than your arm, roof or structure damage, power lines

🚫 Not this
  • ·Lightning and thunder on their own
  • ·Rain that isn't causing flooding
  • ·Ordinary dark clouds, scud, or clouds that only look scary
  1. 1 · The net, if one is up

    When the office activates SKYWARN, a net control on the local repeater takes reports in a set format and relays them straight to the forecaster. Listen first, check in when asked, keep it short: who, what, where, when.

  2. 2 · The office directly

    No net running? Every office has a spotter line or online report form on its SKYWARN page - for you that’s NWS Glasgow. Trained spotters get the number in class; anyone can use the form.

  3. 3 · Tell the room here

    /report hail quarter · 71st & Memorial in #mt-wx puts it in front of everyone watching the state. It does not reach the NWS - do 1 or 2 for that.
