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 Dec 7, 2025 0600 UTC Day 1 Convective Outlook
SPC 1200Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1141 PM CST Sat Dec 06 2025 Valid 071200Z - 081200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS IN THE FL PENINSULA... ...SUMMARY... Isolated damaging winds and a brief tornado or two are possible, mainly across central Florida during the late afternoon and evening. ...FL Peninsula... Abundant convective development is expected later this morning across the north-central to northeast Gulf along a largely west/east-oriented quasi-stationary front. Downstream cloudiness/rain along/north of the front will support pronounced differential boundary-layer heating across it, from central to north FL. With most guidance indicating potential for an MCV to evolve from the morning convection, within the broadly cyclonic mid-level flow regime across the Southeast, it is plausible that convection may strengthen along the baroclinic zone towards peak heating. Weak mid-level lapse rates will remain a key limiting factor to convective intensity. But adequate deep-layer shear will exist for transient mid-level rotation. With a warm boundary layer anticipated across central to south FL, a few strong gusts capable of localized damaging winds are possible. While the 00Z NAM appears to be an aggressive outlier with stronger low-level mass response, expected modest low-level SRH may be sufficient for a brief tornado or two. ..Grams/Thornton.. 12/07/2025

SPC Dec 7, 2025 0700 UTC Day 2 Convective Outlook
SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1100 PM CST Sat Dec 06 2025 Valid 081200Z - 091200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Aside from the possibility of a couple weak thunderstorms near and, perhaps, inland of southern Florida coastal areas, the risk for thunderstorms will remain negligible across much of the U.S. Monday through Monday night. ...Synopsis... The center of a fairly prominent, but relatively compact mid-level vortex is likely to continue redeveloping east-southeast of southern Hudson/James Bay, into and across the Newfoundland and Labrador vicinity during this period. However, models indicate that large-scale mid-level troughing will be maintained east of the Rockies through the western Atlantic, downstream of persistent broad ridging across the eastern mid-latitude Pacific into U.S Intermountain West. One notable short wave perturbation embedded within the troughing is forecast to accelerate east-northeast of the southern Appalachians, across and offshore of the southern Mid Atlantic, but this may contribute to suppression of subtropical ridging as far south as the Caribbean and Bahamas. In lower levels, an associated reinforcing intrusion of cooler/drier air appears likely to contribute to the southward advancement of the primary cold front through much of the remainder of the Florida Peninsula and Gulf Basin. At the same time, it appears that another notable short wave perturbation, progressing through the crest of upstream ridge, will provide support for surface cyclogenesis to the lee of the Canadian and northern U.S. Rockies by late Monday night. This likely will be accompanied by downslope aided warming across much of the high plains, but dry, stable conditions will be maintained there and across much of the remainder of the U.S. ...Southern Florida/Keys... Latest model output remains varied concerning potential for thunderstorm development along/ahead of the southward advancing front. Mid/upper support appears weak, with potential for appreciable destabilization, particularly inland of coastal areas, limited as well. ..Kerr.. 12/07/2025

SPC Dec 7, 2025 0830 UTC Day 3 Severe Thunderstorm Outlook
SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0114 AM CST Sun Dec 07 2025 Valid 091200Z - 101200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... The risk for thunderstorms appears negligible across the U.S. Tuesday through Tuesday night. ...Discussion... Models continue to indicate little substantive change to the large-scale mid/upper flow impacting the U.S. through this period. Broad ridging is likely to persist across the eastern mid-latitude Pacific into the U.S. Intermountain West and Rockies, with downstream troughing east of the Rockies through the Atlantic Seaboard and western Atlantic. The troughing is likely to be reinforced by another significant short wave perturbation, digging within northwesterly flow to the lee of the crest of the ridge. It appears that this will be accompanied by a rapidly migrating cyclone across the northern Great Plains through much of the upper Great Lakes region by late tonight. In the wake of this feature, models indicate an increasingly significant intrusion of cold air will begin to surge southward into parts of the northern Great Plains and upper Mississippi Valley, preceded by strengthening flow veering to an increasing westerly component as far south as the Gulf coast vicinity. Even as the Gulf boundary layer begins to modify to the north of a stalling and weakening front, south of the Florida Peninsula through the southern Gulf Basin, appreciable inland moisture is unlikely through this period and beyond. ..Kerr.. 12/07/2025
