WW 4 TORNADO AL FL GA CW 091205Z - 091900Z
URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 4 NWS Storm Prediction Center Norman OK 705 AM EST Tue Jan 9 2024 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Southeastern Alabama Northern Florida and central/eastern Florida Panhandle Southern Georgia Coastal Waters * Effective this Tuesday morning and afternoon from 705 AM until 200 PM EST. * Primary threats include... A few tornadoes likely with a couple intense tornadoes possible Scattered damaging winds and isolated significant gusts to 75 mph possible Isolated large hail events to 1 inch in diameter possible SUMMARY...A severe squall line, with embedded potentially tornadic circulations and damaging nontornadic winds, will sweep eastward across the watch area through the remainder of the morning, into early afternoon. A few supercells also are possible ahead of the line with a threat for tornadoes (some strong), severe gusts and isolated hail. The tornado watch area is approximately along and 85 statute miles north and south of a line from 10 miles south southwest of Crestview FL to 55 miles east northeast of Valdosta GA. 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...CONTINUE...WW 3... AVIATION...Tornadoes and a few severe thunderstorms with hail surface and aloft to 1 inch. Extreme turbulence and surface wind gusts to 65 knots. A few cumulonimbi with maximum tops to 450. Mean storm motion vector 23035. ...Edwards Read more

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1056 AM CST Tue Jan 09 2024 Valid 101200Z - 111200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected on Wednesday. ...Synopsis... A strong mid/upper-level trough and related deep cyclone are forecast to move quickly into eastern Canada and the western Atlantic early in the forecast period. Weak convection may be ongoing at the start of the period near Cape Cod and the coast of Maine, but instability appears too weak to support lightning potential before convection moves offshore. Otherwise, a large upper trough will remain over most of the CONUS, with multiple embedded shortwaves moving through broad cyclonic flow. One embedded shortwave may produce weak convection capable of sporadic lightning flashes across parts of the Great Basin during the afternoon/evening. Cold temperatures aloft (colder than -30C at 500 mb) may support shallow convection capable of occasional lightning flashes near the Pacific Northwest coast. Elsewhere across the CONUS, generally dry/stable conditions should limit thunderstorm potential on Wednesday. ..Dean.. 01/09/2024 Read more
