<br />In addition to the SPC's information and products, the local National Weather Service Forecast Office
<br />issues a Hazardous Weather Outlook (HWO), generally 1-2 times per day, as situations warrant, to share
<br />thoughts about the potential for severe weather, including hail. These outlooks often discuss likely timing
<br />and locations.
<br />4.3.4.10. Detection & Warning
<br />Local responsibility for detecting and warning citizens about severe hail lies with the National Weather
<br />Service forecast office in Chanhassen. The primary means to communicate urgent storm location and
<br />timing information is with Severe Thunderstorm and Tornado Warnings. These warnings indicate that
<br />severe weather is imminent and will be affecting the warned area for a specified period of time. As with
<br />watches, hail can be expected in both Severe Thunderstorm and Tornado Warnings, and neither is a better
<br />indicator than the other of hail risk.
<br />The NWS uses a combination of trained spotters and radar to detect severe hail. NWS Chanhassen has a
<br />RADAR site for remote monitoring of hail -containing storms --the NEXRAD WSR-88D in Chanhassen.
<br />Numerous tools and algorithms enable NWS staff in Chanhassen to use this system for identification of
<br />severe hail in thunderstorms.
