This chart presents the total number of Local Storm Reports disseminated by the NWS by month and year.

Autoplot 171 produces a similar plot, but contains totals of Watch, Warnings, and Advisories issued.

This is how some of the LSR summary types map to database queries, FWIW:

  • All LSR Types -
  • All LSR Types except HEAVY RAIN + SNOW - and typetext not in ('HEAVY RAIN', 'SNOW', 'HEAVY SNOW')
  • One Inch and Larger Hail - and typetext = 'HAIL' and magnitude >= 1
  • Two Inch and Larger Hail - and typetext = 'HAIL' and magnitude >= 2
  • Three Inch and Larger Hail - and typetext = 'HAIL' and magnitude >= 3
  • Four Inch and Larger Hail - and typetext = 'HAIL' and magnitude >= 4
  • Thunderstorm Wind Gust >= 58 MPH - and type = 'G' and magnitude >= 58
  • Thunderstorm Wind Gust >= 75 MPH - and type = 'G' and magnitude >= 75
  • Any Wind Gust >= 100 MPH - and typetext in ('DOWNBURST', 'HIGH SUST WINDS', 'MARINE TSTM WIND','NON-TSTM WND GST', 'TSTM WND GST') and magnitude >= 100
  • Convective LSRs (Tornado, TStorm Gst/Dmg, Hail) - and typetext in ('TORNADO', 'HAIL', 'TSTM WND GST', 'TSTM WND DMG')
  • Convective minus automated station gusts - and typetext in ('TORNADO', 'HAIL', 'TSTM WND GST', 'TSTM WND DMG') and upper(source) not in ('MESONET', 'ASOS')
  • TSTM and NON-TSTM Wind Damage - and typetext in ('TSTM WND DMG', 'NON-TSTM WND DMG')
  • Winter Precipitation (Snow, Sleet, Freezing Rain) - and typetext in ('SNOW', 'SLEET', 'FREEZING RAIN', 'HEAVY SNOW', 'BLIZZARD')
