US Tornado Alert News
Tornadoes are fast-moving and unpredictable
Tornadoes are fast-moving and unpredictable, with winds that can devastate buildings and hurl debris over long distances. Survivors often face immediate dangers from collapsing structures, flying debris, and power outages. Preparedness involves identifying safe indoor areas, such as basements or interior rooms without windows, and creating go-bags with essential supplies, including food, water, and flashlights. With SimpliGO, users can access tornado preparedness programs from agencies like the National Weather Service (NWS), offering advice on how to shelter in place and protect their families. Through its RSS News Feeds, the app keeps users updated on tornado warnings and weather developments in their area, allowing them to act quickly. The app also helps users locate local stores to purchase emergency supplies like tarps, tools, and backup lighting.

MD 2159 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR SOUTHWEST INDIANA AND FAR NORTHERN KENTUCKY.

Concerning...Severe potential...Watch unlikely Valid 191242Z - 191415Z Probability of Watch Issuance...20 percent SUMMARY...Isolated damaging wind gusts are possible this morning across southwest Indiana and far northern Kentucky. DISCUSSION...A focused area of ascent in the left-exit region of the upper jet and on the leading edge of the mid-level vorticity maximum has resulted in some stronger/fast-moving convection across southern Illinois this morning. A few estimated 60 mph wind gusts and a measured 62 mph wind gust have been associated with this cluster of storms thus far. While downstream instability remains weak (100-200 J/kg MUCAPE per SPC mesoanalysis), the strong forcing should continue to support an isolated damaging wind threat as this cluster of storms moves across southern Indiana and far northern Kentucky this morning. A severe thunderstorm watch is not expected. ..Bentley/Smith.. 10/19/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...LMK...IND...PAH...

SPC 1300Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0735 AM CDT Sun Oct 19 2025 Valid 191300Z - 201200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM PARTS OF THE UPPER OHIO VALLEY/CENTRAL APPALACHIANS INTO THE MID ATLANTIC AND SOUTHERN NEW ENGLAND...AND THE NORTHEAST GULF COAST... ...SUMMARY... Isolated strong to severe storms are possible this morning from south Alabama into southwest Georgia and the Florida Panhandle. Localized wind damage will be possible later today from upper Ohio Valley/central Appalachians into parts of the Mid Atlantic. Late tonight, localized wind damage and possibly a brief tornado will be possible from the northern Mid Atlantic into parts of southern New England. ...Synopsis... Water-vapor imagery this morning shows a powerful mid- to upper-level trough from western Ontario southward to the central Gulf Coast. This upper feature will attain a negative tilt as it moves towards the Eastern Seaboard tonight. A cyclone analyzed this morning over Lake Huron will move north-northeastward toward Hudson Bay, while a trailing cold front will push east-southeastward through parts of the Southeast, Ohio Valley, and Mid Atlantic. ...FL Panhandle vicinity... An ongoing band of convection will continue to move eastward across the northeast Gulf Coast as the airmass attempts to slowly destabilize ahead of it. The latest surface observations confine the richer moisture to the immediate coastal counties (i.e., beaches and bays) of the FL Panhandle, where upper 60s to low 70s deg F dewpoints reside. Relatively poor lapse rates will limit updraft vigor and the overall coverage/intensity of strong to locally severe storm activity. Nonetheless, the moist low levels in the presence of moderate speed shear in the surface-2km layer will perhaps support an isolated threat for a brief/weak tornado and/or a damaging gust. This activity will likely weaken towards midday as large-scale ascent focuses farther north and away from the region. ...Eastern OH into the central Appalachians and Mid Atlantic vicinity... Buoyancy will remain quite limited through most of the day along/ahead of the cold front from the upper OH Valley/central Appalachians into the Mid Atlantic. However, low/midlevel flow will be strong, with 40-50 kt in the 850-700 mb layer. Recent convection-allowing model guidance agrees in showing a developing low-topped convective band initially over eastern OH spreading into western PA coincident with weak instability. Have correspondingly adjusted the western bound of the wind risk to account for this model trend. Late in the period, somewhat richer low-level moisture (with dewpoints in the low 60s F) will advect inland into northern parts of the Mid Atlantic and southern New England. Buoyancy may become sufficient for somewhat deeper convection, as indicated by a modest increase in HREF calibrated thunderstorm probabilities between 06-12Z. With strong low-level flow/shear in place, locally damaging wind and possibly a brief tornado could accompany convection along the front into early Monday morning. ..Smith/Bentley.. 10/19/2025

SPC Oct 19, 2025 Day 4-8 Severe Weather Outlook
Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0353 AM CDT Sun Oct 19 2025 Valid 221200Z - 271200Z ...DISCUSSION... In the wake of the strong upper low over the eastern US, thunderstorm chances will be temporarily muted across the central and eastern US with surface high pressure and offshore flow limiting available instability. Isolated thunderstorms are possible late D4/Wed over parts of the Southwest ahead of a southern stream shortwave trough moving onshore from the eastern Pacific. However, moisture and buoyancy should be quite sparse, suggesting only isolated coverage and negligible severe risk. ...Southern Plains to the lower MS Valley D5-D8... The shortwave trough over the Southwest is forecast to move into the southern Plains as high pressure over the eastern US settles along the Gulf Coast. As the trough crosses the Rockies, a lee low should develop, allowing for modest low-level moisture return over parts of the lower MS Valley and southern Plains. Cooling mid-level temperatures and moistening of the airmass over TX/OK should support increasing thunderstorm chances through the end of the week, with thunderstorm potential extending into the ArkLaTex and lower MS Valley next weekend. Some severe potential is apparent as westerly flow aloft increases amidst the returning moisture/instability. However, details such as the degree of destabilization, timing/structure of the upper trough, and the potential for organized storms remains highly uncertain. 15% severe probabilities could be introduced in future outlook cycles should confidence in organized severe potential increase.
