Widespread damaging winds expected with scattered significant gusts to 90 mph likely Widespread large hail expected with scattered very large hail events to 4 inches in diameter likely A few tornadoes possible SUMMARY...Numerous severe thunderstorms are expected to develop and track rapidly eastward across the watch area through the afternoon evening. Supercells capable of giant hail, damaging winds, and isolated tornadoes will be the main threat early. Storms will organize into multiple fast-moving bowing lines through the evening with a risk of widespread damaging winds. The severe thunderstorm watch area is approximately along and 135 statute miles east and west of a line from 55 miles southwest of Alva OK to 45 miles northwest of Russell KS.

Local NWS offices concurrently issue Watch County Notification (WCN) messages that list subdivisions within their designated area of responsibility that the office has considered to be in the initial watch; WCN messages—which the SPC uses as the basis for their Watch Outline Update product—are updated to denote changes to the watch by local WFOs, which are provided responsibility for adding or removing counties/subdivisions from the watch, extending its time of expiration, or cancelling the watch entirely if conditions no longer support a severe weather threat (if atmospheric conditions have become less conducive to form severe thunderstorms or were insufficient for severe weather development compared to earlier forecast analysis). The SPC updates Watch Outline Updates at least on an hourly basis to incorporate changes made by the accordant WFOs in their Watch County Notification messages.
450:, issues component watch products to communicate the approximate area, primary hazards and other pertinent information about the severe thunderstorm watch to the public, NOAA meteorologists, emergency management and aviation personnel. The graphical and text Public Watch products—in addition to outlining the approximate affected area, valid time, meteorological and aviation discussions, and other pertinent information—includes language specifying the forecast severe weather threat (e.g., "widespread large hail and isolated very large hail events to 3 inches in diameter likely, scattered damaging wind gusts to 70 mph likely, a tornado or two possible") in the primary hazards list. The Watch Probability Table describes probabilities for all modes of severe weather, including probabilities of 10 or more severe wind or hail events and one or more reports of winds exceeding 65 knots (75 mph) or hailstones exceeding two inches (5.1 cm). (Typically, the minimum event probabilities for a severe thunderstorm watch issuance require an ~30% chance of 10 or more wind and hail reports and, for PDS watches, a 70% chance of one or more reports of >65 kt winds and/or >2-inch hail within the watch area over the valid time period.)
476:)—and the NWS offices decide what counties to remove from the watch (the local offices will almost always follow the SPC recommendation on the status messages). If conditions are no longer favorable for severe convective thunderstorms in the watch area, the severe thunderstorm watch may be cancelled outright; occasionally, a severe thunderstorm watch, if not merely a section of it, may be replaced by a tornado watch should conditions that were originally forecast to be conducive for non-tornadic severe thunderstorms evolve to allow an increased possibility of tornado formation, and likewise may replace a tornado watch if conditions for tornadogenesis are no longer considered favorable. If no convective development or reported severe weather occurs, this leads to a severe thunderstorm watch "bust", which can factor into determinations by the SPC and National Weather Service offices on whether to cancel the watch.
