A storm system will likely bring the first accumulating snow to the higher elevations of the central Appalachians and the interior Northeast late week into the weekend. In the low elevations, precipitation will mostly fall as rain. Visit weather.gov for more details.

Enjoy the milder temperatures across the East because colder air is on the way 🥶. The next storm system will usher in high temperatures in the 40s and 50s, along with rain and blustery conditions.

You may have heard there is a threat for snow in the Northeast/Mid-Atlantic late this week. Here is the latest information on that possibility. Please stay weather aware at weather.gov for the latest on the storm!
Confidence is high that a low pressure system will develop across the Ohio Valley Wednesday and then shift off the Mid-Atlantic coast while strengthening Friday. Trends in the model guidance suggest a slightly faster system with less overall precipitation. The threat for at least some impactful high elevation snow remains, but the risk has decreased in lower elevations. The exact placement of the storm — small shifts in the track will greatly change impacts. The amount of snow that may occur, and what impacts will result from this snow. The impacts to coastal regions due to gusty winds and onshore flow. Confidence in storm development remains high, but details will continue to adjust. The threat for low elevation snow has decreased, but high elevation snow and coastal impacts are likely. Keep up to date with the latest at weather.gov
