How We Track Tornadoes For This Area (58643)
This page tracks live tornado alerts, radar updates, and nearby warnings for 58643. This specific location's boundary is used to focus the map, compare active National Weather Service alert polygons, and calculate exactly how far nearby tornado threats are from this area.
Geographic Data Used For This Location
The following location-specific geographic values are utilized for tracking tornado threats to this area. The internal point and bounding box summarize the location area, while the full geometry coordinate set is used to construct the actual boundary shown on the map and to perform our precise tracking calculations.

Location Boundary Data Source
For ZIP code pages, this website uses Census ZIP Code Tabulation Area data. ZCTAs are Census geographic areas that approximate ZIP code service areas for mapping and statistical use. Extreme Weather Tracking processes this geographic data into lightweight location-specific boundary files. The full coordinate geometry from each boundary file is used to draw the exact geographical area on our live map and compare that area against active weather alert polygons.

How Tornado Threat Distances Are Calculated For This Location
The distance values shown in the "Closest Tornado Threats" table — and used to trigger our browser-based alarm — represent the approximate edge-to-edge distance in miles between the 58643 boundary area and each active National Weather Service alert polygon. A distance of 0 miles means the alert polygon overlaps or is contained within the tracked location boundary.
Distances are not calculated from a single center point or internal point coordinate. Instead, the full boundary geometry of 58643 — the same coordinate set used to draw the location boundary on the map — is compared against the full polygon geometry of each active weather alert. This means a tornado warning that is close to the edge of 58643 but not overlapping it will show a short but non-zero distance, while one that crosses into the boundary area will show 0 miles.
Live Tornado Tracking — FAQ (Frequently Asked Questions)
Does this interactive map only show confirmed tornadoes that are actually on the ground?
No. This tornado tracking page focuses on active NWS Tornado Warning polygons. A Tornado Warning may be issued when a tornado has been confirmed visually, reported by trained observers, or indicated by weather radar. Many dangerous tornado threats are detected through radar-indicated rotation, especially when rain, darkness, terrain, or visibility issues make direct observation difficult. That means the map can include tornado threats before there is a confirmed on-the-ground tornado.
Does the map show EF0–EF5 tornado ratings in real time?
No. Tornado intensity ratings are generally assigned after the storm, once damage surveys can be performed. Real-time Tornado Warnings usually do not include an official EF-scale rating, so this page does not attempt to classify live tornado warnings by EF0, EF1, EF2, EF3, EF4, or EF5 strength.
Does the tornado tracker include waterspouts?
If the NWS issues a polygon-based Tornado Warning for a waterspout or tornado threat over water, that warning can be included on the map. The page is driven by the official alert event and polygon data, not by a separate land-only tornado database.
Are the tornado warning polygons the exact area that is actively being damaged by a tornado?
No. The polygon shows the official Tornado Warning area from the NWS. It does not mean every point inside the polygon is currently being damaged by a tornado. It means the warned area is at risk and should be treated seriously according to the alert text, instructions, and timing.
Does this page provide information about the exact future path of the tornado?
Not as a guaranteed path line. Tornado Warning text often includes useful details such as the storm location, movement direction, movement speed, source, hazard, and impacted areas. Those details can help users compare the warning area against 58643 on the map, but tornado motion can change quickly, so the full warning polygon should be treated as the practical risk area.
What should I use if I want to track other severe weather threats near 58643?
This page is focused specifically on live tornado tracking for 58643. To monitor other severe weather categories for this same location, use the related pages for live thunderstorm tracking, live flooding tracking, or the broader live severe weather tracking map.
Weather Data Sources, Radar Processing, & Severe Weather Tracking Methodology
Extreme Weather Tracking uses official United States weather datasets as raw input data for this severe weather tracking application. Instead of simply embedding external weather maps or republishing raw alert feeds, this website processes, transforms, organizes, filters, and visualizes multiple live weather datasets into a location-focused interactive severe weather monitoring system.
National Weather Service (NWS) Alert Processing
Severe weather alerts, warning polygons, event timing, and alert details are sourced from the National Weather Service. Extreme Weather Tracking processes this live alert data into interactive map overlays, categorized alert layers, color-coded polygon systems, stacked overlapping-alert interfaces, closest-threat calculations, browser-based alarm functionality, and location-specific severe weather tracking pages.
Raw NWS polygon coordinate data is transformed into customized interactive map layers with dynamically assigned styling rules, warning-category filtering, active/expired alert handling, polygon overlap detection, popup interfaces, category-specific visual grouping systems, zoomable map interactions, and quick-navigation links that can automatically focus and zoom the map toward specific severe weather threats near each page's dedicated geographical location. Alert polygons are also compared directly against tracked location boundaries to calculate approximate edge-to-edge severe weather threat distances for the specific location.
NOAA Radar Data Processing
Radar imagery displayed on this website is based on NOAA MRMS (Multi-Radar Multi-Sensor) weather radar datasets. Instead of directly embedding static NOAA radar images, Extreme Weather Tracking downloads raw NOAA radar reflectivity data, processes the binary radar grid values, converts the reflectivity measurements into custom-generated radar imagery, and builds optimized radar overlay layers for use within the interactive map system.
The radar processing pipeline includes decompressing NOAA GRIB2 radar datasets, exporting raw reflectivity grids, interpolating radar values, converting reflectivity intensities into customized radar color mappings, generating optimized PNG radar image chunks, and constructing radar overlay layers aligned to precise geographic coordinate boundaries. These processed radar layers are then combined with live NWS warning polygons and tracked location boundaries within the interactive map interface.

Extreme Weather Tracking is not an official government weather service. Always follow instructions from the National Weather Service, local emergency management officials, and other official safety authorities during severe weather events.
