Severe Storms

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0752 PM CDT Thu Apr 10 2025 Valid 110100Z - 111200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE SOUTHEAST INTO THE SOUTHERN APPALACHIANS... ...SUMMARY... Scattered strong to severe thunderstorms are expected across parts of the Southeast this evening, northward into the southern Appalachians. Large hail and damaging winds will be the main threats. ...Southeast/Southern Appalachians... The latest water vapor imagery shows a cyclonic flow pattern over the eastern U.S., with multiple embedded shortwave troughs. One of these features appears to be in the mid Mississippi Valley, with a second located in the southern Appalachians. At the surface, surface dewpoints are mostly in the 40s F from northern sections of the Southeast northward into the southern Appalachians. A low is analyzed in northeast Alabama, where surface dewpoints are locally maximized with dewpoints in the lower 50s F. An outflow boundary extends from west to east from northern Mississippi to northern Georgia. To the south of this boundary, surface temperatures near 70 F are contributing to RAP-analyzed MLCAPE around 1000 J/kg. This instability will help maintain convective development through the evening. At mid-levels, a jet streak is currently moving through the central Plains and lower Mississippi Valley. The left exit region of the jet is located over northern sections of the Southeast. Strong deep-layer shear and lift associated with this feature will continue to support severe thunderstorm development this evening. Supercells and short bowing line segments will likely be capable of producing wind damage. The large-hail threat will be most likely with supercells. This evening, the severe threat is expected to shift southward with time into parts of east-central Mississippi, central Alabama and west-central Georgia. By late evening, the severe threat should become isolated and marginal as instability decreases across the Southeast ..Broyles.. 04/11/2025 Read more

MD 0443 CONCERNING SEVERE THUNDERSTORM WATCH 135...136... FOR WESTERN TENNESSEE...NORTHERN MISSISSIPPI...NORTHERN ALABAMA
Mesoscale Discussion 0443 NWS Storm Prediction Center Norman OK 0508 PM CDT Thu Apr 10 2025 Areas affected...Western Tennessee...northern Mississippi...northern Alabama Concerning...Severe Thunderstorm Watch 135...136... Valid 102208Z - 110015Z The severe weather threat for Severe Thunderstorm Watch 135, 136 continues. SUMMARY...Severe wind gusts and large hail are expected with convection as it spreads southeast this evening. DISCUSSION...Mid-level heights are falling across the Mid South this evening as a 500mb speed max digs across eastern KS toward northern MS. Left-exit region of this jet appears partly responsible for an expanding cluster of thunderstorms along the cold front over western TN. Additionally, while the boundary-layer lapse rates are quite steep across much of this region, surface temperatures are considerably warmer across northern MS into central AL where readings are in the lower 80s. As profiles cool aloft, the greatest buoyancy should focus across northern MS into northern AL. Frontal convection may continue to grow upscale due to the aforementioned exit region and thermodynamic profiles favor strong downdrafts, in addition to large hail. Severe storms should spread across northern MS and northern AL through mid evening. ..Darrow.. 04/10/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...OHX...BMX...HUN...MEG...

URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 136 NWS Storm Prediction Center Norman OK 335 PM CDT Thu Apr 10 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Northern and Central Alabama Far Eastern Arkansas Northern and Central Mississippi Far Southern Middle Tennessee * Effective this Thursday afternoon and evening from 335 PM until 1100 PM CDT. * Primary threats include... Scattered damaging winds likely with isolated significant gusts to 75 mph possible Scattered large hail likely with isolated very large hail events to 2 inches in diameter possible SUMMARY...Robust thunderstorms will continue to develop this afternoon and spread southeastward through the evening. Supercells will pose a threat for large hail generally ranging from 1-2 inches in diameter. Scattered severe/damaging winds, with peak gusts up to 65-75 mph, should also occur as clusters form later this afternoon and evening. The severe thunderstorm watch area is approximately along and 70 statute miles north and south of a line from 55 miles north northwest of Greenwood MS to 25 miles northeast of Anniston AL. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU6). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Severe Thunderstorm Watch means conditions are favorable for 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. Severe thunderstorms can and occasionally do produce tornadoes. && OTHER WATCH INFORMATION...CONTINUE...WW 135... AVIATION...A few severe thunderstorms with hail surface and aloft to 2 inches. Extreme turbulence and surface wind gusts to 65 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 31035. ...Gleason Read more

MD 0444 CONCERNING SEVERE THUNDERSTORM WATCH 137... FOR NORTHERN GEORGIA
Mesoscale Discussion 0444 NWS Storm Prediction Center Norman OK 0652 PM CDT Thu Apr 10 2025 Areas affected...Northern Georgia Concerning...Severe Thunderstorm Watch 137... Valid 102352Z - 110145Z The severe weather threat for Severe Thunderstorm Watch 137 continues. SUMMARY...Scattered severe thunderstorms are expected this evening. DISCUSSION...Convection is gradually expanding in areal coverage this evening, likely in response to the left-exit region of an approaching mid-level speed max. West-southwesterly boundary-layer inflow is also contributing, as this trajectory is allowing higher instability air mass across northern AL to spread downstream into northern GA. Latest radar data suggests the most robust updrafts are generating hail, much of it approaching golf ball size. Additionally, damaging winds are likely noted as the steepest lapse rate plume does extend into this portion of GA. This expanding convective corridor will gradually sag southeast as the evening progresses. ..Darrow.. 04/10/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...GSP...FFC...BMX...
