Europe is bracing for a major weather shift this weekend, as an intense Arctic cold outbreak targets eastern, central, and southeastern regions. The season’s most severe winter storm is set to hit the Balkan peninsula, potentially dumping up to 50 cm (20 inches) of snow across areas from Romania to Ukraine. This significant event is forecasted to extend into the end of November...
After weeks of unusually warm weather, Europe is on the verge of a significant meteorological change. A classic dipole pattern is emerging, characterized by a robust high-pressure system in the west and a deep, cold trough in the east. Starting this weekend, this pattern will introduce a major Arctic cold outbreak across eastern and central Europe, extending to the Balkans.
As colder Arctic air clashes with warmer Mediterranean and Black Sea regions, a potent winter storm is expected to form over Greece, rapidly intensifying into a significant blizzard in Bulgaria, Romania, Moldova, and Ukraine from Saturday to Sunday, November 25 – 26, 2023. This event is set to cover areas from Sofia through Bucharest to Odesa and Kyiv with deep fresh snow, reaching local accumulations of around 50 cm (20 inches) in just 36 – 48 hours, accompanied by strong winds.
In the wake of this storm, central Europe will be engulfed by a much colder air mass, with significant snowfall predicted for the northern Alps due to persistent north-northwesterly winds. Meanwhile, other areas will see less snowfall, as the initial cold blast will act more as a fast-moving frontal system with limited moisture, until it encounters warmer air masses towards the Eastern Mediterranean.
This major dipole weather pattern is a classic setup for an intense cold outbreak from the Arctic into Europe. Temperatures across eastern and central Europe are expected to drop significantly, around 8 – 12 °C (14 – 22 °F) below normal on Saturday. While the west maintains near-normal temperatures, the Arctic cold pool will intensify over Eastern Europe and the Balkans through Sunday and Monday, November 26 and 27.
Intense winter storm brings heavy snow and freezing temperatures to the Plains and Rockies, U.S.
A significant winter storm is affecting the Rockies and Plains, bringing heavy snowfall and temperatures well below normal this holiday weekend. Forecasts predict snow accumulations of 10 – 15 cm (4 – 6 inches) in western Nebraska and central Kansas, and up to 30 – 45 cm (12 – 18 inches) in southwest Colorado. The system, which is also expected to impact the eastern states early next week, poses a severe travel risk due to gusty winds and heavy snow.
A powerful winter storm is tracking across the Intermountain West into the central Plains, bringing a notable drop in temperatures and hazardous travel conditions. The storm’s path will impact areas from the eastern Great Basin through the central Rockies to the central High Plains. Western Nebraska and Kansas are preparing for snow accumulations of 10 – 15 cm (4 – 6 inches) on Friday and Saturday, November 24 and 25, 2023, with potential for higher amounts in some areas. Southwest Colorado is expected to receive significant snowfall, with estimates of 30 – 45 cm (12 – 18 inches).
The storm’s impact is intensified by gusty winds, with snow rates reaching up to 2.5 cm (1 inch) per hour at times. This combination is expected to create particularly hazardous conditions for travelers in western and central Kansas this Saturday. Additionally, a wintry mix is forecast from the Texas Panhandle through northern Oklahoma into eastern Kansas and Missouri, resulting in light snow accumulations.
Following a cold front, below-average temperatures are anticipated for much of the U.S. this weekend. The central Plains will experience some of the most extreme temperature drops, with highs forecasted at -6 to 1 °C (20s and 30s °F) and morning lows dropping to -9 to -7 °C (16 – 19 °F). Wind chills in these areas could reach and even drop below -18 °C (0 °F).
The eastern U.S. will also face lower than average temperatures, with highs in the -6 to 1°C (20s and 30s °F) range for the Great Lakes and Interior Northeast. The Midwest, New England, and Mid-Atlantic states will see highs from 1 to 10°C (30s to 50s°F). The South, while warmer, will experience slightly below average temperatures.
