Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 227 PM EST Sat Feb 08 2025 Valid 00Z Sun Feb 09 2025 - 00Z Tue Feb 11 2025 ...Quick moving winter storm to bring moderate to heavy snow to the Northeast tonight along with freezing rain to parts of the central Appalachians... ...Colder temperatures for the South after recent record warmth and colder trending temperatures for the north-central U.S... As an area of low pressure tracks eastward from the Ohio Valley late this evening into Sunday morning, wintry precipitation will spread eastward into the upper Ohio Valley, northern Mid-Atlantic and Northeast. Snow, sleet and freezing rain will advance into northern Ohio, portions of Pennsylvania and the northern Mid-Atlantic through this evening before changing over to rain tonight for coastal regions of the Mid-Atlantic. However, many areas will remain as frozen precipitation, including portions of the Allegheny Mountains and Laurel Highlands of western Maryland into southern Pennsylvania where a quarter inch of ice (locally higher possible) can be expected by Sunday morning. Across central New York into central New England, precipitation will remain all snow and bands of heavy snow are likely to impact these regions with snowfall rates of 1-2 inches per hour. Storm total snowfall of 6 to 12 inches is expected from central New York State to the Boston metropolitan area. While this winter storm will quickly exit into the Atlantic ocean early on Sunday, travel is expected to be dangerous through Sunday morning and power outages and damage to trees from the ice will be possible. After the storm departs the East Coast, the lower 48 should see a day of fairly quiet weather for Sunday. After another day of record breaking warmth across Texas into the lower Mississippi Valley on Saturday, a cold front will advance southward towards the Gulf Coast on Sunday, dropping temperatures dramatically in its wake across the South with forecast high temperatures 20 to 30 degrees colder from central Texas into portions of the lower Mississippi Valley on Sunday compared to Saturday. A few record high temperatures in the upper 70s to lower 80s will remain possible on Sunday from the central Gulf Coast into the Southeast but cooler temperatures will continue to sink south Sunday night into Monday. Across the north-central U.S., the upper level pattern will favor reinforcing shots of colder air into the region over the next couple of days. This will result in a cooling trend from Montana into the northern Plains where high temperatures are expected to only range from below zero into the lower teens on Monday, or about 20 to 30 degrees below average. By late Monday, wind chill values of 40 to 50 degrees below zero will be possible across northern Montana into northern North Dakota, resulting in rapid frostbite potential on exposed skin.
