INDIANA — A dramatic reversal in long-range weather modeling is reshaping expectations for December across Indiana and much of the northern United States. Updated CFSv2 data now shows a stronger Arctic influence, a sharper jet-stream dip, and colder temperature anomalies—a major shift from the warm, stable pattern originally forecast in early November. A Flattened Jet…
Waldron, Indiana — A massive dome of Arctic air is pushing south out of Canada this week, setting up a potentially disruptive pattern shift across the United States. Meteorologists warn that this developing configuration in the jet stream could slow east-coast flow, alter storm tracks, and increase the potential for larger winter storm systems heading…
UNITED STATES — A powerful lake-effect snow event is expected to intensify late Wednesday night through early Thursday, bringing a high probability of more than six inches of snow to several Great Lakes communities. New ensemble data shows a concentrated corridor of heavy snowfall forming downwind of Lakes Erie and Ontario, with Buffalo, Erie, Cleveland,…
UNITED STATES — A major upper-air pattern developing over North America could influence Christmas week weather across the central and eastern United States, according to new long-range ensemble guidance. While early projections strongly favored a widespread warm pattern heading into the holiday, the latest 500mb height anomaly maps suggest a possible shift that forecasters say…
ILLINOIS — A quick-moving clipper system is set to sweep from Illinois through Indiana, Ohio, and into West Virginia, producing a sharp, narrow snow band capable of dropping 2 to 4 inches, with isolated pockets near 5 inches where the strongest forcing locks in. The system arrives Thursday night and continues into Friday, targeting major…
MINNESOTA — An exceptionally dangerous blast of Arctic air is set to plunge into the Midwest this weekend, bringing wind chills as low as –50°F across portions of Minnesota, North Dakota, South Dakota, and Wisconsin. Forecasters warn that these temperatures pose an immediate risk to life, with frostbite possible in as little as 5–10 minutes…
UNITED STATES — Meteorologists are closely watching a developing upper-air pattern that could determine whether the East Coast will face small, fast-moving snow events or the potential for a major winter storm in the coming days. New model analyses show that the Northern Jet Stream and Southern Jet Stream remain separated, preventing the type of…
FLORIDA — A rare level of forecast agreement across three major weather ensemble systems is pointing toward a significantly warmer-than-normal Christmas for much of the United States, including the Deep South, Midwest, and East Coast. New long-range data from the European Ensemble (EPS), the AI-enhanced ECMWF AIFS Ensemble, and the American GFS Ensemble all show…
WASHINGTON — More than 100,000 people in western Washington could face evacuation orders overnight as forecasters warn of historic and potentially record-breaking river flooding fueled by another round of 3–5 inches of additional rainfall expected through Saturday morning. New high-resolution precipitation guidance shows extreme rainfall totals targeting Skagit, Snohomish, and surrounding river basins, where soil…
ALABAMA — New long-range guidance from the Climate Prediction Center (CPC) shows the Deep South trending much warmer than normal between December 18 and December 24, sharply reducing the odds of any Christmas-week snowfall across Alabama, Georgia, and Mississippi. The newly issued 8–14 Day Temperature Outlook highlights a pronounced warm pattern developing across the southern…
