UNITED STATES — A noticeable moderation trend is now underway across much of North America, signaling a shift away from persistent, entrenched cold toward a more variable temperature pattern that will bring frequent ups and downs every few days. The latest temperature analysis shows arctic air retreating northward, while milder Pacific and southern air masses…
UNITED STATES — New guidance from the ICON model is signaling a high-impact coastal storm developing by early Monday, February 16, with a broad precipitation shield spreading across the Mid-Atlantic and parts of the Northeast. While details will continue to evolve, the data shows a deepening low-pressure system capable of producing heavy rain, interior snow,…
UNITED STATES — A developing storm system is expected to bring widespread heavy rainfall across the Tennessee Valley and parts of the Lower Ohio Valley this weekend, increasing the risk of flooding—especially in areas where frozen or partially frozen ground could limit water absorption. Forecast guidance valid from Friday, February 13 through Sunday, February 15…
UNITED STATES — At first glance, new European (ECMWF) model guidance shows a large, organized storm system moving into the central and eastern United States by Saturday, raising early concerns for severe weather. However, a closer look at the atmospheric setup suggests that low instability will likely keep severe storms in check, shifting the primary…
UNITED STATES — A widespread and unusually intense cold outbreak gripped the eastern United States early Sunday morning, with dozens of locations across the Mid-Atlantic and Northeast approaching or breaking daily low-temperature records, according to temperature analysis from February 8. The cold was not confined to northern states. Data shows record-level chill extending deep into…
UNITED STATES — New National Weather Service precipitation anomaly data shows a widespread and significant drying trend across much of the central and eastern United States, reinforcing signals that the broader weather pattern is transitioning away from mid-winter and toward an early spring regime. The map, covering the last 14 days from January 26 through…
UNITED STATES — New European model guidance highlights a critical upper-level interaction unfolding through Thursday evening, a phase that meteorologists say will ultimately determine where the next significant winter weather threat sets up along the East Coast. According to the data, forecast confidence drops sharply beyond Thursday night, as small timing differences between key atmospheric…
UNITED STATES — Long-range weather guidance is once again hinting at a potential Presidents Day weekend storm, with the European (ECMWF) model re-introducing a coastal system affecting the eastern United States. While confidence remains low at this distance, the setup shown in the latest data is enough to put forecasters back into tracking mode. The…
UNITED STATES — Meteorologists across the Great Lakes and Midwest, including Michigan, Wisconsin, Illinois, Indiana, and Ohio, rely on a specialized satellite product known as Day Cloud Phase to better understand winter weather conditions at the surface and in the atmosphere. During the winter months, traditional satellite imagery can struggle to distinguish between clouds and…
UNITED STATES — A complex winter storm that affected large portions of Massachusetts, Connecticut, Rhode Island, eastern New York, Long Island, and parts of southern Maine between February 6 and February 9, 2026, delivered widespread snowfall totals largely in line with forecasts issued days in advance, even as localized banding and mesoscale features created inevitable…
