This page allows you to generate a GIS shapefile of NWS issued Local Storm Reports for a time period of your choice. Please be sure to read the archive status and dbf schema below. The IEM's archive is certainly not complete or official.
Looking to automate the downloading of LSRs?
You can use the following URI form to get the most recent number of seconds worth of LSRs. Note that these times are based on the valid time of the LSR and not the issuance of the text product itself that contained the LSR.
fmt=csv portion to return the zipped shapefile.

Shapefile DBF schema:
VALID Timestamp of LSR in GMT/UTC time MAG Magnitude value of the LSR WFO Weather Forecast Office originating the LSR TYPECODE 1 character identifier of the report type, IEM specific TYPETEXT Textual value of LSR type used in report CITY Location used for the LSR COUNTY County/Parish of the LSR city STATE Two character state abbreviation SOURCE Who reported the LSR REMARK Text summary with the LSR LAT Latitude LON Longitude UGC IEM computed NWS UGC code (6 character), sometimes null UGCNAME IEM computed NWS UGC name (128 character), sometimes null
- Before 1 Dec 2006, there was no differentiation between Snow and Sleet reports.
- 18 July 2022: Added output fields that attempt to cross reference NWS UGC County/Zones database to the referenced county/state found in the LSR text. This all is sub-optimal, but works in 99% of cases.
