Live updates: Tracking holiday weekend snow threat as El Niño signals grow for 2026

Seattle-Tacoma International Airport (SeaTac) is currently facing operational constraints due to low ceilings. This typical Pacific Northwest gray-out means clouds are sitting low enough to force air traffic controllers to increase the spacing between arriving aircraft, naturally leading to a backlog of flights.

Currently, general arrival and departure delays are remaining relatively manageable at 15 minutes or less, though this number is expected to increase through the afternoon.

While the current delays are minor, low ceilings often result in "gate holds," where your plane is held at its origin to manage the volume of arrivals in Seattle.

If you are heading to the airport, keep a close eye on your airline's app for real-time gate changes or pushback adjustments.

The four-person crew will launch to the International Space Station aboard the SpaceX Dragon spacecraft tomorrow morning.

NASA and SpaceX had delayed the launch of the Crew-12 mission on Tuesday due to weather.

The previous Crew-11 mission was cut short due to an undisclosed medical issue with one of the crewmembers.

While the chance of a blockbuster blizzard has faded, the FOX Forecast Center warns that the I-95 corridor isn't entirely in the clear for the upcoming holiday weekend.

Despite an ongoing thaw, pushing temperatures into the 40s and 50s, a complex storm system tracking through the South is expected to graze the Mid-Atlantic and Northeast late Sunday into Monday.

Meteorologists are closely monitoring the transition zone, where just a slight shift in the storm's track could determine whether cities like Washington, D.C. and New York City see a cold rain or a couple inches of snow.

According to the latest analysis, there is notable model ensemble support for a light snow event along the I-95 corridor.

While individual operational models have vacillated on the exact rain-snow line, the broader ensemble means—which average dozens of potential outcomes—suggest that enough cold air may linger at the surface to support a few inches of accumulation.

This wintry fringe remains the primary forecast hurdle for President's Day travel, as even minor accumulations could create slick spots on roads that have only recently begun to melt out from January’s deep freeze.

Millions across the South are bracing for a Valentine's Day washout as a powerful 1,000-mile-wide storm system sweeps through the region, bringing a risk of severe thunderstorms and flash flooding. FOX Weather is tracking widespread rain totals of 1 to 4 inches from Texas to the Carolinas, with localized pockets of up to 6 inches where storms train over the same locations. The most intense activity is expected on Saturday, particularly across Louisiana, Mississippi, and Alabama, where Gulf moisture could fuel damaging wind gusts and isolated tornadoes, potentially disrupting holiday travel and outdoor celebrations.

After weeks of dry weather across the West, the Rockies are finally beginning to receive much-needed snow.

Many snowpacks throughout the region are between 25-60 percent below their average — a critical deficit for ski resorts, as well as the water supply for drinking and agriculture in the summer months.

Winter Weather Alerts are in place across parts of Utah, Wyoming and Colorado through Thursday.

After a historically dry January that saw California’s snowpack plummet to just nearly half of normal, a major pattern shift is finally delivering the "insane" snow totals needed to rescue the state’s frozen reservoir.

The FOX Forecast Center is tracking a series of relentless storms that could dump 5 to 10 feet of snow in the high country through next week.

Until this week, the Sierra Nevada was enduring a critical moisture deficit. A warm, dry January wiped out early-season gains, leaving the statewide snowpack at a third of typical numbers.

The Northern Sierra has been the hardest hit, sitting at just 39% of normal to date, while the Southern Sierra has fared slightly better at 72%.

This week's snow is just the opening act. While the first wave is delivering a refresh of 12 to 36 inches, a much more potent, slow-moving system is forecast to arrive late Saturday.

This "monster" storm is projected to bring feet of heavy snow to mountain passes over several days, potentially boosting the statewide snowpack by double digits in a single week.

Since the Sierra snowpack traditionally supplies 30% of California’s freshwater, this "insane" February surge is critical for replenishing the state's water infrastructure before the dry summer months.

A new era of high-definition weather tracking has arrived in the White Mountains of New England. In a first for New Hampshire, the Mount Washington Observatory (MWOBS) has installed a ground-based scanning LiDAR system at Bretton Woods to map the atmosphere in unprecedented 3D detail.

This cutting-edge "laser radar"—a Vaisala WindCube 200S—allows meteorologists to peer into the boundary layer, the turbulent slice of air where terrain meets sky and fuels the region's notoriously lethal weather.

This doppler scanner is monumental for our wind, cloud, and general lower-atmosphere studies, especially regarding the boundary layer, which heavily influences Mount Washington’s uniquely extreme weather.

Situated at 1,600 feet, the scanner sends vertical and horizontal laser beams several kilometers into the sky, measuring how winds shift as they collide with the Presidential Range.

The system provides 360-degree data coverage for nearly nine miles, meaning researchers can now monitor wind profiles directly over the summit of Mount Washington in real-time.

By tracking clouds, aerosols, and turbulence, the LiDAR helps scientists understand why winds intensify so dramatically over complex terrain, providing a bankable look at atmospheric dynamics that traditional stations simply can't capture.

The project, funded by a congressional request from U.S. Senator Jeanne Shaheen, is designed to serve both the scientific community and the public.

Beyond improving high-resolution forecasting, the data will be used to enhance safety for the thousands of hikers and skiers who visit the range each year.

MWOBS says it plans to integrate this 3D mapping into their public website, allowing anyone to see the invisible forces shaping the "home of the world's worst weather."

As the Pacific Ocean shows signs of a rapid shift, FOX Weather meteorologists are closely watching how a brewing El Niño could rewrite the script for the 2026 Atlantic hurricane season.

While El Niño is often viewed as a "shield" for the Atlantic, history proves that even in a "quiet" year, it only takes one breakthrough storm to define a season.

The transition from our current La Niña to a likely El Niño by late summer 2026 creates a hostile environment for tropical systems.

The primary mechanism is vertical wind shear—the change in wind speed and direction with height. During El Niño years, the subtropical jet stream strengthens, sending high-speed westerly winds across the Atlantic and Caribbean. These winds act like a scissors, effectively cleaving the tops off developing tropical depressions before they can organize into powerful hurricanes.

While the statistical probability of a major hurricane landfall drops during El Niño, this protection is never a guarantee. History is littered with catastrophic exceptions like Hurricane Andrew (1992), which became one of the most destructive Category 5 hurricanes in U.S. history, and Hurricane Alicia (1983) which clobbered the Texas coast, causing billions in damage.

The current 2026 outlook suggests that while we could see a lower total number of named storms, the presence of exceptionally warm Atlantic sea surface temperatures could still allow any storm that avoids the wind shear to intensify rapidly.

For residents along the Gulf and East Coasts, the brewing El Niño might lower the odds, but it doesn't lower the stakes.

NASCAR drivers and fans are eyeing this weekend's cross-country storm, ahead of the unfurling of the green flag Sunday afternoon at the Daytona 500.

Zach Dean, NASCAR columnist for Outkick.com, discussed the impact of rain on the big race with FOX Weather Meteorologists Stephen Morgan and Marissa Torres.

Recent analysis shows warmer weather and a week of sunshine has vanquished much of the snow left behind after January's historic winter storm.

Thanks to a recent pattern shift, warmer weather is expected to grip much of the East over the coming week, meaning more puddles than piles of snow.

A powerful, 1,000-mile-wide storm system is set to sweep across the South this Valentine’s Day weekend, bringing widespread drenching rain and the threat of severe thunderstorms from Texas to the Carolinas. Rain totals are expected to reach 1 to 4 inches, with localized "training" storms potentially dumping up to 6 inches, which could trigger flash flooding in urban areas and low-lying neighborhoods.

Flurries are flying west of Interstate 95 this morning under a deck of thick clouds. Those flurries are expected to continue into early afternoon, but accumulating snow is unlikely.

"Slush season" has arrived. Temperatures in major hubs like Philadelphia and NYC are flirting with the mid-30s and 40s today, but the ground remains chilled from the recent deep freeze.

This creates a "slushie" effect where the top layer of snow melts into a gray soup while the bottom layer remains a treacherous sheet of ice.

Even with temperatures rising, the February sun angle is still relatively low. This means that while your lawn might look clear, north-facing stoops, alleyways, and parking spot savers (those giant piles of gray snow) will likely linger for days as frozen obstacles.

As we head into the Valentine's and President's Day weekend, a shift toward even milder air and potential rain will turn those remaining snowbanks into mini-lakes, making high-quality waterproof boots the must-have fashion accessory of the week.

After weeks of relentless arctic blasts and impactful winter storms, a significant pattern flip is providing the Northeast with a much-needed thaw. High-pressure is replacing deep-digging troughs, shifting the focus of cold and snow to the Western U.S. and allowing unseasonably mild air to flood the Atlantic corridor.

For millions from D.C. to Boston, this means a break from the shovel; daily highs are projected to climb into the 40s and even 50s through next week, effectively putting winter on a temporary hiatus.

The upcoming week’s forecast is remarkably quiet, with most major metro areas seeing little to no snow accumulation. While this weekend's big storm may bring spotty rain or a light wintry mix to the interior mountains late this weekend, coastal hubs like New York City and Philadelphia are trending toward a snow-free stretch through next week.

This prolonged reprieve is helping to dent the glacial shell that has covered the region, providing ideal conditions for travel and outdoor plans as we head toward the President's Day holiday.

The multi-year grip of La Niña is finally loosening. According to the latest update from the Climate Prediction Center, there is now a 60% chance that the Pacific will transition to "ENSO-neutral" conditions between in the weeks ahead.

While chilly sea surface temperatures still linger in the central Pacific, a significant surge of subsurface warmth is moving eastward—acting like an underwater heater that is rapidly eroding the cold La Niña base.

This shift means the reliable "steering wheel" of our winter weather is being removed, likely leading to a more variable and unpredictable spring for much of the U.S.

Looking further ahead, the "neutral" phase is expected to persist through the summer, but a bigger flip is on the horizon.

Forecast models are now signaling a 50-60% chance of El Niño forming by late summer or fall of 2026.

If this rapid transition verifies, it could have major implications for the 2026 hurricane season, as El Niño typically increases wind shear in the Atlantic, which can help suppress storm development.

For now, we are in a "wait and see" period as the atmosphere begins to decouple from the old La Niña pattern and resets for the year ahead.

FOX Weather has just received the latest weekly U.S. Drought Monitor and it shows worsening drought conditions across the Southern U.S.

According to the report , conditions worsened followed another mostly dry week in the High Plains, western Midwest, the eastern southern Plains of Oklahoma and Texas eastward into the Lower Mississippi Valley and the western Carolinas.

Despite scattered precipitation in some locations, rain and snow deficits continue to grow, with drying soils and low streamflows supporting intensification of drought conditions.

In southern Georgia and Florida, fire danger continues to rise.

Wildfire activity increased during the week, and multiple water management districts, including the South Florida Water Management District, have issued water shortage advisories or warnings due to declining groundwater and surface water levels.

The report says from August 14, 2025, through February 10, 2026, Rio Grande City, Texas ranks as the fifth warmest and third driest on record dating back to 1928, while McCook, Texas ranks as the second warmest and sixth driest since 1942 according to NWS and NOAA data.

Tampa is experiencing travel trouble this morning as a Dense Fog Advisory remains in effect until 10:00 a.m. ET, covering Hillsborough and surrounding counties.

Visibility at Tampa International Airport (TPA) and across major corridors like I-75 has dropped to a dangerous quarter-mile or less, forcing several early morning flights into delays. The fog is expected to thin out by late morning, leading to a mostly sunny afternoon.

The Climate Prediction Center is set to release an update on the current status of La Niña in the Pacific, and the expected development of El Niño later this year.

FOX Weather will provide comprehensive coverage when the report is released later this morning.

While millions in the South prepare for a rainy washout, the Northeast and Mid-Atlantic are eyeing a complex forecast for the Valentine’s and President's Day weekend. After a brief thaw earlier this week, a clash of seasons is set to unfold as a sprawling weekend storm brings the threat of snow back to the region.

Forecast confidence is currently split between "wet and white" as a surge of milder air battles lingering cold entrenched in the interior. The FOX Forecast Center says most computer model guidance has pulled back when it comes to snow for the region. As of now, it appears the higher terrain of West Virginia and Maryland could still see flakes late Sunday into Monday.

For major cities like Washington D.C., Philadelphia, and New York City, the forecast is welcome news. While early guidance suggested a major hit, the most recent trends favor a brief rain-snow mix or just plain rain altogether. Accumulating snow appears unlikely, though a slight shift in the storm's track could easily push numbers higher.
