Several tornadoes and a couple intense tornadoes likely Widespread damaging winds and isolated significant gusts to 75 mph likely Scattered large hail events to 1.5 inches in diameter possible SUMMARY...A maturing squall line will surge eastward from Arkansas into western Tennessee and northwestern Mississippi through early tonight, with an accompanying threat for swaths of damaging winds (up to 75 mph) and tornadoes with embedded circulations. Farther south, a few semi-discrete supercells are expected ahead of the squall line, from northeast Louisiana across southeastern Arkansas and west central/northwestern Mississippi. A few strong-intense tornadoes will be possible in this corridor with any persistent supercells later this evening. The tornado watch area is approximately along and 120 statute miles east and west of a line from 25 miles northwest of Memphis TN to 20 miles south of Natchez MS. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU6). PRECAUTIONARY/PREPAREDNESS ACTIONS...

427:, and coastal marine zones) included in the broader watch area: Watch County Lists (WCL), which are produced internally preceding the watch issuance for collaborative use with local NWS offices to outline counties and equivalent subdivisions being proposed for inclusion in the watch, and Watch Outline Update (WOU) messages, a public list of the determined watch subdivisions published upon the initial tornado watch issuance. 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 tornadoes or were insufficient for tornadic 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.
412:, issues component watch products to communicate the approximate area, primary hazards and other pertinent information about the tornado 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 tornado threat (e.g., "several tornadoes and a few intense tornadoes likely"), and attendant severe wind and hail threats (e.g., "widespread damaging wind gusts to 70 mph likely, isolated very large hail events to 2 inches in diameter possible") in the primary hazards list. The Watch Probability Table describes probabilities for all modes of severe weather, including probabilities of two or more tornadoes and one or more strong to violent tornadoes. (Currently, the minimum tornado probabilities for a tornado watch issuance require a ~30% chance of two or more tornado reports and, for PDS watches, an 80% chance of one or more strong tornadoes within the watch area over the valid time period, although that criterion was previously lower.)
438:)—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 tornadoes in the watch area, a tornado watch may either be replaced by a severe thunderstorm watch or cancelled outright; likewise, a tornado watch may replace a severe thunderstorm watch, if not merely a section of it, should conditions that were originally forecast to be conducive for non-tornadic severe thunderstorms evolve to allow an increased possibility of tornado formation. If no convective development or tornadic activity occurs, this leads to a tornado watch "bust", which can factor into determinations by the SPC and National Weather Service offices on whether to cancel the watch.

outside the outlined quadrilateral; however the local
Weather Forecast Office is tasked with determining which counties should be included in or, in lieu of a new downstream watch, added to the designated watch area. The WFOs monitoring their sector of the watch area can also consult, via conference call, with the Storm Prediction Center to relay and determine locally dictated changes to the tornado watch, regarding replacement of the watch and extensions of time and areal coverage if conditions warrant.
