Along with the cooler air, some lingering moisture may move up the East Coast during the day Thursday. As that moisture runs into colder air higher in the atmosphere, there could be a brief window for snow showers.
The FOX Forecast Center said any snow that reaches the ground is unlikely to stick because of the recent warmth. Some accumulation is possible across the Mid-Atlantic and any elevated locations.

After Thursday, temperatures across the East will settle back closer to seasonal averages, with no immediate signs of another major burst of spring warmth returning anytime soon.
The Southwest is set to remain well above average through the end of March, according to the long-range temperature outlooks from the Climate Prediction Center. Their 2-3 week outlook also maintains above-average temperatures across much of the West through the first week of April.
