For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU4). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Tornado Watch means conditions are favorable for tornadoes and severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. && OTHER WATCH INFORMATION...This tornado watch replaces tornado watch number 23. Watch number 23 will not be in effect after 955 PM EST. AVIATION...Tornadoes and a few severe thunderstorms with hail surface and aloft to 1.5 inches.

SEVERE WEATHER OUTLOOK FROM SPC
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1028 AM CST Sun Jan 22 2017 Valid 221630Z - 231200Z ...THERE IS A HIGH RISK OF SEVERE THUNDERSTORMS OVER PARTS OF SOUTHERN AND CENTRAL GEORGIA...NORTHERN FL...AND EXTREME SOUTHEAST AL... ...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS OVER PARTS OF AL...FL...GA...AND SC... ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS OVER PARTS OF AL...FL...GA...SC...AND NC... ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER MUCH OF AL...FL...GA...SC...AND NC... ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS OVER MUCH OF THE SOUTHEAST STATES... ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS PARTS OF CENTRAL CA... ...SUMMARY... A severe thunderstorm and tornado outbreak is expected today across north Florida and south Georgia, with the significant severe threat also expected to extend southward into central Florida and northeastward into South Carolina this evening. ...AN OUTBREAK OF SEVERE STORMS AND TORNADOES IS EXPECTED THIS AFTERNOON AND EVENING OVER PARTS OF NORTHERN FLORIDA, AND CENTRAL/SOUTHERN GEORGIA... ...Southern AL/North FL/Southern GA... The late morning surface analysis shows a rapidly deepening low near MOB, with a convectively reinforced warm front extending eastward from the low along the FL/GA border. This low is forecast to deepen over 12mb in the next 12 hours as it tracks northeastward. This rapid cyclogenesis will be accompanied by very strong low and mid level wind accelerations across parts of GA/FL. The result will be a zone of impressive shear profiles in the warm-sector of the low, along with ample low level moisture and rather steep lapse rates. Forecast soundings in the HIGH risk area are characterized by effective helicity values of 500-700 m2/s2 overlapping MLCAPE of 1000-1500 J/kg. This rare parameter space will support the risk of long-track strong tornadoes across the HIGH risk area. Also, very strong low and mid level winds and steep lapse rates suggest a significant risk of bowing structures capable of widespread damaging winds and large hail. The line of storms will eventually sag southward across the entire FL Peninsula overnight with a continued severe risk. ...Northeast AL/Northern GA... As the rapidly deepening surface low lifts northeastward, a plume of rather steep mid level lapse rates and strong winds aloft will wrap around the low. This may result in an arc of strong to severe storms affecting parts of northeast AL and northern GA later this afternoon and evening. Ample low level vorticity along this arc may be sufficient for a few tornadoes, along with large hail and damaging wind gusts. ...Carolinas... The convective evolution is uncertain over parts of SC/NC later today due to the widespread upstream thunderstorm coverage expected, and the persistent thunderstorm complex now over southeast GA. Given the strength of the wind fields and cyclogenesis, there remains a significant threat of severe storms spreading northeastward across much of SC and into southeast NC after dark, with damaging winds and a few tornadoes being the main threat. Its unclear how far north and west this threat will extend, but have lessened severe probabilities over parts of western/central NC where cool air and clouds are likely to persist. ...Central CA Coast... Multiple bands of showers and thunderstorms are expected to spread inland and affect the central CA coast this afternoon. Cool temperatures aloft and steep mid level lapse rates, combined with the strong west-southwesterly winds aloft, will support a risk of fast-moving bowing structures capable of locally damaging winds and hail. ..Hart/Leitman.. 01/22/2017 CLICK TO GET WUUS01 PTSDY1 PRODUCT NOTE: THE NEXT DAY 1 OUTLOOK IS SCHEDULED BY 2000Z CURRENT UTC TIME: 1906Z (2:06PM), RELOAD THIS PAGE TO UPDATE THE TIME
