ILLINOIS — A powerful surge of Arctic air has caused a dramatic temperature collapse across Illinois, with readings dropping as much as 50 degrees in just 24 hours, according to early-morning data Monday. The sharp cooldown followed a fast-moving cold front that swept across the Midwest overnight, bringing some of the most extreme short-term temperature…
Missouri — A rare and extreme “blue norther” cold front swept through Missouri, delivering one of the most dramatic temperature collapses the state has seen in decades and sending St. Louis from near-record warmth to snow and near-freezing conditions in just hours. The data shows temperature drops of 50 to 60 degrees within a single…
Southern California — Strong Santa Ana winds intensified across Los Angeles, San Bernardino, Riverside, and San Diego counties on Monday, peaking during the afternoon hours before remaining gusty through Tuesday afternoon, according to the latest wind gust forecasts and real-time observations.

SOUTHERN CALIFORNIA — A multi-day storm system is set to impact Southern California through New Year’s Eve and New Year’s Day, bringing periods of moderate to heavy rainfall, gusty winds, and elevated risks of flooding, mudslides, and downed trees, according to forecast data from the National Weather Service. The areas facing the greatest impacts include…
MISSOURI — A violent polar vortex–fueled bomb cyclone triggered an extraordinary temperature collapse of up to 55 degrees Fahrenheit across Missouri, marking one of the most extreme 24-hour temperature swings seen this winter. Newly analyzed temperature-change data shows the cold front racing southeast through the Central Plains, Midwest, and Lower Mississippi Valley, replacing mild air…
UPPER PENINSULA AND LOWER MICHIGAN — A powerful winter system delivered significant snowfall across Michigan’s Upper Peninsula, while strong winds and lighter accumulations created a chaotic and hazardous day across Lower Michigan and parts of the western Great Lakes. Snowfall totals clearly show the Upper Peninsula as the hardest-hit area, with some locations seeing well…
