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.

SPC Oct 20, 2025 2000 UTC Day 1 Convective Outlook
SPC 2000Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0245 PM CDT Mon Oct 20 2025 Valid 202000Z - 211200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... No severe threat is expected today or tonight across the continental U.S. No change is made to this outlook from the previous outlook. ..Broyles.. 10/20/2025 .PREV DISCUSSION... /ISSUED 1115 AM CDT Mon Oct 20 2025/ ...Synopsis and Discussion... Current satellite imagery shows a pair of shortwave troughs traversing the CONUS: a sharp, well-defined wave moving across the Northeast and a lower-amplitude, more broad wave progressing through the northern High Plains/northern Plains. The majority of the CONUS is characterized by dry and stable conditions as high pressure follows in the wake of a strong cold front associated with the Northeast shortwave trough. The only exception is across New England and far southern FL, which remain ahead of the cold front. The cold front is expected to continue eastward/northeastward through New England today, while becoming increasingly occluded as the associated surface low tracks more northerly. A band of showers is ongoing across New England now, but scant buoyancy across the region has kept storms shallow thus far. A few instances of lightning are still possible within this band as well as a few stronger, convective augmented gusts. However, the overall severe probability should remain too low to introduce an outlook area. A few isolated thunderstorms are possible ahead of the front in south FL as well, but weak shear should preclude any severe threat. Two other areas could see isolated thunderstorms this afternoon/evening and overnight, both associated with the western shortwave trough moving across the northern Plains into the Upper Midwest. A few isolated thunderstorms are possible this afternoon/evening across southeast MT and adjacent northeast WY and western SD amid strong forcing for ascent and cooling mid-level temperatures. Aa instance or two of small hail is possible as well. Farther southeast, a few thunderstorms are possible overnight into early tomorrow morning from the Arklatex into northwest MS as the cold front associated with this shortwave moves through. These storms should be post-frontal with very limited severe potential.

SPC Oct 20, 2025 1930 UTC Day 3 Severe Thunderstorm Outlook
SPC 1930Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0203 PM CDT Mon Oct 20 2025 Valid 221200Z - 231200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe storms are not expected on Wednesday. ...Synopsis... A deep upper low will remain dominant across the northeast states on Wednesday, while a shortwave trough moves across southern CA and into the desert southwest. Scattered thunderstorms will be possible beneath the cold upper low over parts of New England, and along the immediate leeward shores of the lower Great Lakes. No severe storms are anticipated. Other scattered thunderstorms will be possible in a plume of mid-level moisture ahead of the western trough - mainly from southern UT into parts of CO/NM. Again, no severe storms are currently expected. ..Hart.. 10/20/2025

SPC Day 2 Fire Weather Outlook
SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0245 PM CDT Mon Oct 20 2025 Valid 211200Z - 221200Z ...Southeast Piedmont... Dry southwest flow ahead of an approaching cold front is expected across portions in the Piedmont region of the VA, Carolinas and northern GA Tuesday. Relative humidity as low as 20% amid dry fuels will align, but limiting factor will continue to wind speeds, struggling to reach 15 mph by Tuesday afternoon. Nonetheless, a locally elevated fire weather threat will exist across the region. ...Central and Southern Plains... Dry, post-frontal flow is still expected to support an elevated fire potential across north-central TX Tuesday. Northeast winds of around 15 mph, along with relative humidity dropping to 15% in some areas will align with dry fuels (ERCs near the 90th percentile) to promote elevated fire weather conditions across north-central TX, where Elevated highlights remain. Farther north, enhanced north/northwest winds and low relative humidity behind the cold front are likely across portions of the Central Plains. However, a less receptive fuelscape should mitigate significant fire potential in this region. ..Williams.. 10/20/2025 .PREV DISCUSSION... /ISSUED 0147 AM CDT Mon Oct 20 2025/ ...Synopsis... Post frontal northeasterly breezes will overlap relative humidity reductions to around 20 percent across portions of north-central Texas. Though this is occurring on the cool side of the front, temperatures will still remain fairly warm, with fuels exceeding the 75th percentile for dryness given below normal rainfall and ongoing drought conditions. An Elevated area was maintained with this outlook to cover potential for some increased fire potential. ...Please see www.spc.noaa.gov/fire for graphic product...
