The United States is currently under the influence of a powerful and varied weather pattern that is bringing high-impact conditions from coast to coast. A substantial surge of Arctic air, coupled with active storm systems, means nearly every region faces a unique weather threat.
Here is a breakdown of the dominant weather patterns you need to be aware of:
1. The Deep Freeze: Arctic Air Invades the East
A massive blast of polar air is plunging southward, threatening to challenge or break low-temperature records from the Plains all the way to the East Coast.
- Plains & Midwest: Frigid air has already settled in, driving temperatures well below average. Dangerous wind chills are a major concern, and preparation for extreme cold should be prioritized.
- Eastern U.S.: This arctic air mass will keep temperatures well below normal across the Midwest, Appalachians, and Northeast for the remainder of the week and into the weekend.
2. Winter Hazards: Snow Squalls and Heavy Mountain Snow
Major wintry conditions are active in both the West and the Northeast.
- Northeast & Great Lakes: An arctic cold front is sweeping through, triggering dangerous snow squalls with the potential for whiteout conditions and rapid reductions in visibility. Lake-effect snow is also active, bringing moderate to heavy totals to downwind areas. Travel conditions are extremely hazardous.
- Rockies & Pacific Northwest: A persistent winter storm is delivering heavy snowfall to the Central Rockies and High Plains, with some mountainous areas receiving 6 to 12 inches of accumulation, locally higher. Another system is moving into the Pacific Northwest, bringing fresh mountain snow to the interior regions.
3. Gulf Coast & Southeast: Heavy Rain and Flood Risk
While the north shivers, the Gulf Coast and Southeast are bracing for excessive moisture.
- Heavy Rain & Thunderstorms: A frontal boundary interacting with the cold air is generating moderate to heavy rainfall, along with embedded thunderstorms, for the western and central Gulf Coast. This system will push eastward into the Southeast through the end of the week.
- Flash Flood Concern: Due to the intensity of the rain, there is an isolated risk for flash flooding along the Gulf Coast and the Southeast, particularly in low-lying and poor drainage areas.
