2024 Thanksgiving Snow Outlook: From Rockies to Great Lakes – See Your State’s Forecast

This Thanksgiving week, the weather across the United States will undergo dramatic changes due to a moderate atmospheric river and a surface low pressure system that will traverse the nation. These systems will unfold a series of significant weather transformations, progressing from the West to the East Coast, impacting a multitude of regions along the way.

Initial Impact in Western States

Starting in the Western US, the atmospheric river is expected to bring “anomalous moisture,” leading to heavy precipitation.

Southern and central California are particularly vulnerable to flash flooding due to this excess rainfall and snowfall.

The Sierra Nevada, Intermountain West, and Central Rockies will witness significant snowfall, with higher elevations potentially receiving between 1 to 3 feet of snow on Tuesday.

This combination of heavy coastal and mountain rain could trigger instances of flash flooding and landslides, especially on the windward foothills of the southern Sierra Nevada below 8,000 feet.

Progression Towards Midwest and Great Lakes

As the system advances eastward from Wednesday night to Thursday night, it will carry additional moisture from the Gulf of Mexico and the Atlantic, enhancing its intensity.

The Midwest and Northeast will experience snow showers, particularly around the Great Lakes region.

The Upper Peninsula of Michigan and areas downwind of Lake Ontario could receive 4 to 8 inches of snow by Thursday morning.

This continuous snow shower activity will challenge both residents and travelers in these areas.

Anticipated Weather Changes

With the storm gathering strength, various regions will face notable weather shifts throughout the week.

The mix of rain and snow will require close monitoring as AccuWeather points out that the precise track and intensity of the storm will determine where the rain-snow line sets up and the amount of snow accumulation.

Potential travel disruptions are expected due to the winter conditions that accompany this system.

Looking ahead, anticipate an Arctic blast following Thanksgiving, as the storm system moves forward, affecting regions from Northern California to the Eastern US with persistent cold weather and heavy snowfall.

Western States Snow Forecast

Heavy Snowfall in Sierra Nevada

Buckle up, folks! The Sierra Nevada is in for a winter wonderland this Thanksgiving week.

This region can expect significant snowfall, ranging from one to three feet in higher elevations.

A moderate atmospheric river is teaming up with a surface low pressure system, bringing a deluge of precipitation.

This hefty snowfall event is poised to start on Tuesday, so if you’re in the area, get ready for some serious shoveling.

Intermountain West and Central Rockies

It’s not just the Sierra Nevada that will see heavy snow.

The Intermountain West and Central Rockies are also bracing for a substantial snowfall, with totals matching that of the Sierra Nevada at one to three feet.

These areas will likely experience the brunt of the storm on Tuesday.

For those living or traveling through these regions: it’s time to hunker down and prepare for some picturesque yet perilous snowy conditions.

Flash Flooding Potential in California

While the higher altitudes are enjoying their snowy scenes, southern and central California have their own weather worries.

The same weather system is bringing heavy precipitation that may lead to flash flooding.

With “anomalous moisture” saturating the area, there’s a heightened risk of landslides, mudslides, and rockslides.

It’s imperative for residents in these areas to stay vigilant and keep abreast of local weather alerts for any sudden changes.

Impact on Higher Elevations

Tuesday’s snowfall will have the most significant impact on higher elevations.

These areas will bear the brunt of the storm’s heavy snow, making them potentially dangerous for travel and outdoor activities.

If you have plans in the mountains this week, it might be best to reschedule or take extra precautions to ensure your safety.

As the week unfolds, this weather system is not only transforming the western landscape but will continue its eastward march, promising to bring more wintery weather and challenges ahead.

Stay tuned for updates on what else this storm system has in store for the rest of the country.

Midwest and Great Lakes Impact

Snow Showers Continuing Across Great Lakes Region

As the storm system progresses eastward, the Midwest and Great Lakes regions can expect a dynamic week of weather.

Snow showers are predicted to persist throughout the region, leading to significant accumulations in some areas.

The snow will not only contribute to picturesque winter landscapes but also pose challenges for daily commutes and travel plans.

Upper Peninsula of Michigan and Lake Ontario Snowfall

The Upper Peninsula of Michigan and the areas downwind of Lake Ontario are particularly in the storm’s sights.

By Thursday morning, these regions could see between 4 to 8 inches of snow.

This snowfall is a result of the storm system gathering additional moisture as it travels eastward, bolstering the snow showers across these areas.

Residents should brace for potential delays and plan accordingly to navigate the winter conditions.

Storm Gathering Additional Moisture as it Moves Eastward

One of the key features of this storm system is its ability to intensify as it moves across the country.

The storm is expected to draw in moisture from both the Gulf of Mexico and the Atlantic Ocean, increasing its strength.

This influx of moisture will not only enhance snow showers in the Midwest and Great Lakes but also set the stage for the next phase of significant weather changes as the system progresses further east.

With these anticipated conditions, communities in the Midwest and Great Lakes should remain vigilant, closely monitor local weather updates, and be prepared for the disruptions that this winter weather might bring.

Post-Thanksgiving Arctic Blast

The culmination of this storm system’s passage across the United States brings a bone-chilling shock with the onset of the Post-Thanksgiving Arctic blast.

Thanksgiving Day’s Arctic Outbreak

The Arctic outbreak is set to begin in the northern Rockies and Plains on Thanksgiving Day.

Residents in these areas will experience a sharp drop in temperatures that will resemble mid-January rather than late November.

The National Weather Service warns that this initial wave of cold air will pave the way for more severe conditions throughout the weekend.

Spreading Cold Front

As the Arctic air mass advances, the cold front will spread southward and eastward through the Plains and Midwest.

Places like Kansas, Nebraska, and Missouri will feel the chill by Friday, with temperatures plummeting rapidly.

By Saturday morning, nearly 196 million Americans could wake up to below-freezing temperatures, a stark contrast to the relatively mild weather much of the country has experienced so far this season.

This cold snap will likely result in widespread frost and potential damage to any remaining late-season crops.

Residents are advised to take precautions to protect plants, pets, and pipes from the severe cold.

Impact on Daily Life

The drastic temperature drop will not only create hazardous conditions for travel but also increase the likelihood of heating-related incidents.

With colder temperatures persisting, energy consumption is expected to rise, potentially leading to higher utility bills and increased strain on power grids.

Communities should prepare for possible power outages due to the spike in demand.

Travel and Safety Precautions

Travel safety is a significant concern as the nation enters its busiest travel period of the year.

The icy conditions and below-freezing temperatures will affect roadways, making them slippery and dangerous.

Air travel could see delays and cancellations due to de-icing requirements and weather-related operational challenges.

Travelers are encouraged to plan ahead, monitor weather updates, and allow extra time for their journeys to ensure safety.

Throughout this period, it’s crucial for individuals and families to stay informed about the weather forecasts and heed any advisories from local authorities.

Stocking up on essential supplies, ensuring vehicles are winter-ready, and checking on vulnerable neighbors can go a long way in navigating the aftermath of the Arctic blast safely.

The intensity of this cold front will be a critical test for the nation’s infrastructure and preparedness.

As temperatures continue to drop, staying vigilant and adaptive is key to weathering this abrupt winter onset.

Next up, we will explore how the widespread travel anticipated during the Thanksgiving period will face significant disruptions and the essential precautionary measures that travelers should be prepared to take.
