WW 723 TORNADO AL FL GA CW 290655Z - 291400Z
URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 723 NWS Storm Prediction Center Norman OK 155 AM EST Sun Dec 29 2024 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Southeastern Alabama Florida Panhandle to Big Bend Georgia Coastal Waters * Effective this Sunday morning from 155 AM until 900 AM EST. * Primary threats include... A few tornadoes possible Scattered damaging wind gusts to 70 mph possible SUMMARY...A line of strong-severe thunderstorms will continue to move through an environment characterized by modest instability but favorable shear, and may produce occasional embedded tornadoes and/or damaging nontornadic winds. The tornado watch area is approximately along and 90 statute miles east and west of a line from 15 miles southwest of Apalachicola FL to 40 miles northeast of Atlanta GA. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU3). 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 721...WW 722... AVIATION...Tornadoes and a few severe thunderstorms with hail surface and aloft to 1 inch. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 24030. ...Edwards Read more

Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0347 AM CST Sun Dec 29 2024 Valid 011200Z - 061200Z ...DISCUSSION... A broad/expansive upper-level trough will persist over much of the eastern U.S. during the upcoming week, while a ridge of high pressure will extend over the western portion of the CONUS. A series of surface high-pressure systems will result in generally dry/stable conditions and minimal to no chance for thunderstorms through Friday/Day 6. Towards Saturday/Sunday (Days 7 and 8), guidance is varied but does suggest some increase in thunderstorm potential over the south-central U.S. as an impulse over the western U.S. moves east of the Rockies. Uncertainty is high at this relatively extended range on the timing and degree of amplification of this feature, and therefore the overall potential for thunderstorms remains low with this outlook.

SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0212 AM CST Sun Dec 29 2024 Valid 311200Z - 011200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected Tuesday. ...Synopsis... A compact, negatively-tilted upper trough will lift northeast across the Ohio Valley and northeast U.S. Tuesday, as a developing coastal low near the Mid-Atlantic coast moves into southern New England by 12z Wednesday. Strong ascent will overspread this area in advance of a cold front, and an isolated lightning strike or two will be possible within an area of developing precipitation during the afternoon from coastal NC across the Delmarva region. With very minimal MUCAPE expected, coverage should be too sparse for introduction of a general thunderstorm area. Elsewhere, thunderstorms chances will be negligible in the presence of a generally dry and stable air mass over much of the CONUS. ..Bunting.. 12/29/2024 Read more

MD 2313 CONCERNING TORNADO WATCH 722...723... FOR EAST-CENTRAL/SOUTHEAST AL TO WEST-CENTRAL/SOUTHWEST GA
Mesoscale Discussion 2313 NWS Storm Prediction Center Norman OK 0121 AM CST Sun Dec 29 2024 Areas affected...east-central/southeast AL to west-central/southwest GA Concerning...Tornado Watch 722...723... Valid 290721Z - 290815Z The severe weather threat for Tornado Watch 722, 723 continues. SUMMARY...Primary corridor of tornado potential through the pre-dawn hours should exist from southeast of Montgomery, east-northeast along the I-85 to I-75 corridors in Alabama/Georgia. DISCUSSION...After merger of a long-track supercell with the extensive QLCS near the Montgomery area of AL, an embedded bowing structure with mesovortices has formed and recently produced a brief TDS per the MXX 88D. The downstream evolution of this bow/mesovortices will likely contain greater tornado potential within WWs 722/723 during the next few hours. The MXX VWP has sampled a rather enlarged low-level hodograph with 0-1 km shear from 35-40 kts. MLCAPE around 500 J/kg should gradually spread east-northeast as surface dew points slowly increase through the mid 60s from southeast AL/south GA. ..Grams.. 12/29/2024 ...Please see www.spc.noaa.gov for graphic product...

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0146 AM CST Sun Dec 29 2024 Valid 301200Z - 311200Z ...CRITICAL FIRE WEATHER AREA FOR EASTERN NEW MEXICO...WESTERN TEXAS/TEXAS PANHANDLE...FAR WESTERN OKLAHOMA PANHANDLE... ...Synopsis... Enhanced westerly flow aloft will overspread the central/southern Rockies through the base of a mid-level shortwave moving across the central/southern Plains on D2/Monday. Resulting surface cyclogenesis and strengthening lee troughing will lead to an increase in westerly surface winds across portions of the southern High Plains. This will support a broad region of Elevated to Critical fire weather concerns across areas from southeastern Colorado to the Oklahoma Panhandle and into New Mexico and Texas. ...Eastern New Mexico, Texas/Oklahoma Panhandle, Western Texas... Warm/dry/gusty westerly downslope flow is expected across eastern New Mexico into western Texas/Oklahoma Monday. Afternoon relative-humidity reductions to around 10-20 percent (driest across portions of western Texas) will overlap surface winds sustained around 20-25 mph. Fuels within this region have seen drying over the last several days. While latest fuel guidance suggests 100-hr fuels are largely marginal, the extended period of critical winds and relative humidity should lead to further drying (especially of fine fuels), supporting risk for fire spread. The previous D3 70 percent was converted to a Critical area to support this risk. ..Thornton.. 12/29/2024 ...Please see www.spc.noaa.gov/fire for graphic product... Read more

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0144 AM CST Sun Dec 29 2024 Valid 291200Z - 301200Z ...NO CRITICAL AREAS... ...Synopsis... A mid-level ridge across the western US will continue to build and shift eastward across the Rockies today as a mid-level trough exits the eastern US. A cool continental air mass will remain in place across much of the Plains, with generally light winds where the driest conditions are forecast in the southern High Plains. A few westerly downslope breezes will be possible across eastern New Mexico. Overall fire concerns will remain low with little overlap of dry/windy conditions and receptive fuels. ..Thornton.. 12/29/2024 ...Please see www.spc.noaa.gov/fire for graphic product... Read more

WW 721 TORNADO AL FL LA MS CW 290030Z - 290800Z
URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 721 NWS Storm Prediction Center Norman OK 630 PM CST Sat Dec 28 2024 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Southern Alabama The Western Florida Panhandle Southeast Louisiana Southern Mississippi Coastal Waters * Effective this Saturday night and Sunday morning from 630 PM until 200 AM CST. * Primary threats include... Several tornadoes likely with a couple intense tornadoes possible Scattered damaging winds likely with isolated significant gusts to 80 mph possible Isolated large hail events to 1.5 inches in diameter possible SUMMARY...Thunderstorms will continue to pose a threat for tornadoes and severe/damaging winds this evening and overnight. The most intense winds may reach 70-80 mph within the developing line of thunderstorms. A strong tornado also appears possible with any sustained supercell that can be maintained ahead of the line. The tornado watch area is approximately along and 70 statute miles east and west of a line from 40 miles north northwest of Evergreen AL to 70 miles south of Slidell LA. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU1). 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 720... AVIATION...Tornadoes and a few severe thunderstorms with hail surface and aloft to 1.5 inches. Extreme turbulence and surface wind gusts to 70 knots. A few cumulonimbi with maximum tops to 500.

SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1253 AM CST Sun Dec 29 2024 Valid 301200Z - 311200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorm chances appear low on Monday. ...Synopsis... A departing upper-level trough will lift northeast early Monday as a surface cold front moves offshore over New England. An upstream upper-level trough will amplify as it moves into the central Plains, contributing to the development of a surface low near the KS/MO border by afternoon. Low-level moisture will begin to return north across the lower Mississippi Valley/Ark-La-Miss region, however richer moisture will remain confined to near the TX/LA coast. This will limit destabilization potential even as ascent/cooling mid-level temperatures develop near the surface low. Thus, while an isolated lightning strike will be possible in the presence of meager MUCAPE (around 100-200 J/kg) across the mid-Mississippi Valley area Monday night, overall coverage should be less than 10%. Elsewhere across the CONUS, generally dry/stable conditions should preclude thunderstorm potential. ..Bunting.. 12/29/2024 Read more
