Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 234 AM EST Sun Feb 25 2024 Valid 12Z Sun Feb 25 2024 - 12Z Tue Feb 27 2024 ...Heavy snow over parts of the Cascades, the Northern Intermountain Region, Northern/Central Rockies, and higher elevations of the Great Basin... ...Light snow over parts of the Northeast and snow over the Northern Plains on Monday... ...Heavy snow over parts of the Sierra Nevada Mountains on Monday... A strong winter storm and cold front will move into the Northwest on Sunday and progress southeastward into the Northern Rockies on Monday. Heavy mountain snow over the Cascades will impact the passes by late Sunday, with greater than 80% chance of at least a foot of snow above 1500ft through early Tuesday. In addition, snowfall will sometimes become heavy, with rates of 1-2 inches per hour, along with windy conditions, creating areas of blowing snow and drifting snow and significantly reducing visibility. Furthermore, snow squalls are likely along the path of the cold front on Monday over the Northern Intermountain Region/Rockies, which could create a rapid drop in visibility and icing on roadways, leading to dangerous travel. Additionally, much colder air behind the strong cold front will drop temperatures into the teens and colder by Tuesday morning. Further, the system will produce coastal rain over the Northwest, with snow levels lowering to near sea level after the front passes. Overnight Sunday, rain will move into parts of California, with higher-elevation snow. Moreover, on Monday, heavy snow will impact the Sierra Nevada Mountains. A wave of low pressure will move over parts of the Northern Plains by Monday evening as snow develops over the region. There is also a risk of rain/freezing rain moving over parts of the Upper Mississippi Valley. Meanwhile, moisture from the Western Gulf of Mexico will stream northward over the Southern Plains, Middle/Lower Mississippi Valley, and Ohio Valley. The moisture will aid in creating scattered light rain showers over parts of the Ohio Valley overnight Sunday into Monday. By Tuesday, the moisture will produce showers and thunderstorms over parts of the Ohio Valley. Furthermore, upper-level energy will assist in creating light snow over parts of the Northeast overnight Sunday into Monday evening.
