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 2251 CONCERNING HEAVY SNOW FOR CENTRAL IOWA
Mesoscale Discussion 2251 NWS Storm Prediction Center Norman OK 0654 PM CST Sat Dec 06 2025 Areas affected...central Iowa Concerning...Heavy snow Valid 070054Z - 070400Z SUMMARY...Moderate to heavy snow to continue across portions of central Iowa over the next couple of hours. Occasional rates 1"/hr with heavier bands. DISCUSSION...Recent radar and surface observations suggest moderate to heavy snow continues across portions of central Iowa. This is occurring near the surface low and in the region of strong DPVA aloft overspreading central Iowa. Two regions that will favor heavy snow (possible 1"/hr rates) over the next couple of hours are near the zone of 700-850 mb frontogenesis across central Iowa north of Des Moines and in a smaller mesoscale sector along and south of I-80 and trending eastward of I-35 where a more narrow band of heavy snow has developed. Guidance indicates a gradual downward trend in snowfall rates is expected through the late evening/early morning Sunday. However, periods of locally moderate snow may continue at times across northeastern Iowa into southern Wisconsin/northern Illinois. ..Thornton.. 12/07/2025 ...Please see www.spc.noaa.gov for graphic product...

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0652 PM CST Sat Dec 06 2025 Valid 070100Z - 071200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms are possible near a portion of the north-central/northeast Gulf Coast during the early morning Sunday. ...Discussion... Conditions will be too dry/stable for appreciable lightning-producing convection across much of the CONUS through the period. However, elevated thunderstorms are expected to commence across the north-central to northeast Gulf Coast overnight. Some of this activity might approach the nearshore waters and immediate coastline over the MS River Delta and the FL Panhandle before 12Z Sunday. ..Grams.. 12/07/2025

SPC Day 3-8 Fire Weather Outlook
SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0305 PM CST Sat Dec 06 2025 Valid 081200Z - 141200Z ...Synopsis... Surface high pressure moving into the eastern U.S. will promote benign fire weather conditions across the region Day 3/Monday, including additional rainfall over the Southeast along an advancing cold front. A mid-level short wave translating southeastward within broad northwesterly flow aloft should reach the Northern Plains by Day 4/Tuesday. A corresponding surface cyclone over the Dakotas and southward extending lee troughing along the High Plains should support dry and breezy downslope conditions across eastern NM and portions of West TX by Tuesday afternoon. However, even with additional days of drying through Tuesday, fuels are expected to remain muted, reducing the overall fire weather threat. A stronger polar jet develops within a gradually amplifying upper-level wave pattern over CONUS through late next week as mid-level troughing persists across the eastern U.S. while ridging builds further into the western states. This will support another cold air mass intrusion into the eastern U.S. while much of the Great Basin, CA and the Southwest remain dry within a lighter wind regime under the expanding/advancing ridge, limiting broader fire weather concerns. ..Williams.. 12/06/2025 ...Please see www.spc.noaa.gov/fire for graphic product...
