A fresh storm is lining up for the middle of the week across the eastern United States, but this time the bigger story will be soaking rain rather than blockbuster snow for most communities. After a stretch of Arctic air, power outages and coastal snow, the new system is poised to wring out moisture over ground that is already cold and, in many places, snow covered, raising a different set of hazards from flooding to ice.

The setup is classic late-winter whiplash: a stubborn Polar vortex keeping the region chilled while a milder, moisture-rich disturbance rides in from the south. That clash will tilt the balance toward chilly rain in the Southeast and Mid-Atlantic, with a narrower stripe of accumulating snow farther north and inland, and it will unfold against a backdrop of lingering damage from the recent Bomb cyclone and Historic cold.

Rain-dominant storm tracks across the Southeast and Mid-Atlantic

Forecast models show the midweek system drawing Gulf and Atlantic moisture into a broad shield of precipitation that spreads from the Gulf Coast through the Carolinas and into the Northeast. For most of the Southeast, the air near the surface has moderated enough that the incoming moisture will fall as rain, turning what had been a deep freeze into a chilly, soggy stretch from the Gulf Coast to the coastal plain. Forecasters expect the next storm system to bring a welcome dose of rain to the Southeast Tuesday into Wednesday, easing fire concerns and helping replenish soil moisture even as it complicates travel.

As the storm lifts north, the same moisture plume will run into colder air over the interior Mid-Atlantic and Northeast, where the rain-snow line is likely to set up near the Appalachians and interior valleys. That means cities closer to the coast are more likely to see a chilly, wind-driven rain while higher elevations and inland communities pick up a slushy accumulation. The overall pattern fits with guidance that the midweek system will bring more rain than snow to the eastern United States, with the heaviest liquid totals focused along a corridor from the Gulf Coast through the coastal Carolinas and into parts of the I-95 corridor.

Cold pattern locked in by the Polar vortex

The reason this storm can deliver so much rain without fully scouring out the cold is the persistent grip of the Polar vortex over the eastern half of the country. Earlier forecasts warned that the Polar vortex would keep a frigid pattern locked over the region through much of Feb, effectively holding the freezer door open on the central and eastern United States. That entrenched cold has already produced multiple rounds of Arctic air and set the stage for snow cover to expand, especially after the recent coastal storm.

Even as the midweek system taps milder air aloft, the lingering influence of the Polar vortex means temperatures at the surface will stay near or below normal for many areas, especially at night. Another outlook noted that the Polar circulation could unleash repeated waves of cold air, each accompanied by chances for snow or mixed precipitation. That backdrop increases the risk that any overnight rain on frozen ground or existing snowpack could refreeze into ice, particularly on untreated roads and sidewalks.

Storm arrives on the heels of a Bomb cyclone and Historic cold

The midweek rainmaker is not arriving in a vacuum. It follows a Bomb cyclone that rapidly strengthened off the East Coast, bringing blizzard conditions, coastal flooding and a deep freeze to parts of the eastern and central United States. That earlier system, described as a Bomb cyclone off the East Coast, intensified the dangerous cold and contributed to widespread power outages across the South, leaving infrastructure and residents vulnerable to another round of adverse weather.

At the same time, a rapidly intensifying coastal storm delivered Arctic air and heavy snow to the Carolinas and mid-Atlantic, shattering February temperature records in Florida. Reports highlighted Historic cold that broke multiple February records across Florida, underscoring how unusual the recent chill has been even in typically mild parts of the Southeast. With that Arctic air mass still nearby, the incoming storm will be interacting with a landscape of frozen pipes, stressed power grids and residents already worn down by days of extreme conditions.

Snow stripe, advisories and expansive snow cover

While rain will dominate for many, a narrow but impactful band of snow is expected from the Ohio Valley into the interior Mid-Atlantic. One forecast described how another storm would bring a stripe of snow to the Ohio Valley and mid-Atlantic, with meteorologist Courtney Travis noting that some areas could finally get a little relief from the most intense cold even as they trade it for wintry precipitation. That snow band will likely set up along the northwest side of the storm track, where colder air undercuts the moisture plume and supports accumulation on roads and elevated surfaces.

Official alerts are already reflecting the wintry side of the system. A WWA map shows winter weather messaging across parts of the Ohio Valley and central Appalachians, while a separate bulletin labeled Winter Weather Advisory as an URGENT WINTER WEATHER MESSAGE urges drivers to slow down and use caution. On the ground, there is already an Expansive snow cover across the United States, with Charlotte reporting a snow depth of 11 inches following the weekend storm, more than many Northeast cities. That existing snowpack will amplify runoff where heavy rain falls on top of it, increasing the risk of localized flooding and slushy, hard-to-clear streets.

Southern strain, local alerts and travel impacts

In the South, the new storm arrives as communities are still grappling with prolonged outages and lingering cold. Earlier this week, coverage of the Southern U.S. described a second week of biting cold and prolonged outages, with one report noting that the content was available to Open in Our App as the cold stretched into parts of northern Florida. That same cold pattern has left some homes and businesses without reliable heat, so even a shift from snow to cold rain can be hazardous for those still relying on temporary shelters or generators.

Local alerts are underscoring the risks. In eastern North Carolina, a weather alert issued NC Weather Bot and Updated February highlighted hazardous conditions until Tuesday at 10 a.m., signaling that saturated ground and lingering ice will complicate the arrival of new rain. Farther north along the Delmarva Peninsula, a forecast noted that Temperatures will moderate into the mid to upper 30s on Tuesday and Wednesday before another blast of Arctic air arrives, with a period of light snow possible on the backside of the system. For travelers, guidance from midweek forecasts stresses that the combination of rain, snow and lingering ice could impact your travel plans, particularly on secondary roads and during the overnight hours.
