Winter Storm Forecast: Snowfall, Travel Disruptions, and Arctic Air

Substantial Winter Storm Impacts

• ❄️ A significant winter storm is impacting the Midwest and heading towards the Northeast U.S., with the Ohio Valley and Great Lakes regions also affected.
• 🚗 Travel disruptions are expected due to slick roads, with widespread school delays and cancellations anticipated, particularly in the interior Northeast.
• 🌨️ Snowfall totals are projected to range from 1-3 inches across Kansas, Missouri, Chicago, and the Ohio Valley, with 3-6 inches possible in parts of eastern Ohio and western Pennsylvania.

Heaviest Snowfall and Coastal Differences

• 🏔️ The heaviest snow accumulation, potentially 6-12 inches, is expected in northeastern Pennsylvania, upstate New York, and interior New England, especially at higher elevations.
• 🌧️ Major cities along the I-95 corridor, including Baltimore, Philadelphia, and New York City, are forecast to receive mainly rain, with a possibility of brief snow or sleet at the onset.
• 🌊 Coastal areas like Boston may see precipitation start as snow, transition to rain, and potentially back to snow later, while the immediate coastline will primarily experience rain.

Storm Intensity and Travel Disruptions

• 💨 While wind gusts of 30-35 mph are possible along the coast, wind is not expected to be a significant factor in this storm.
• ⚠️ The storm may be close to meeting the criteria for a bomb cyclone due to rapid intensification, but the primary impacts will be snow inland and rain at the coast.
• ✈️ Flight disruptions are anticipated, starting Monday night into Tuesday, with Chicago's O'Hare and Midway airports likely affected. Heavier rain and lower ceilings in the I-95 corridor may cause flight delays rather than cancellations.

Long-Term Winter Outlook and Arctic Air

• 📉 For the I-95 corridor, seasonal snowfall amounts are expected to be below the long-term historic average, continuing a trend from recent winters.
• 📈 Interior areas of the Northeast, including parts of Pennsylvania, upstate New York, and New England, are identified as regions that could see near or above-average snowfall for the season.
• 🥶 A reinforcing shot of arctic air is expected Wednesday into Thursday, bringing temperatures 15-20 degrees below average and the risk of snow squalls, especially in the Great Lakes and interior Northeast.

Weekend Storm Potential

• ❓ A potential storm system is being monitored for Saturday into Sunday, with mixed signals. It could move out to sea or develop along the coastline, bringing a risk of snow and ice to interior sections of the eastern U.S.
