Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 225 AM EST Tue Jan 28 2025 Valid 12Z Tue Jan 28 2025 - 12Z Thu Jan 30 2025 ...Locally heavy snow and snow squalls possible for the Great Lakes and Northeast through Wednesday... ...Flooding rain and severe thunderstorms possible from the southern Plains to the Mid/Lower Mississippi Valley Wednesday into Thursday... ...Well above average temperatures expected across much of the Central and Eastern U.S., while below average temperatures linger in southern California and the Southwest... A slow moving low pressure system will gradually push east across the Southwest and into the southern Plains over the next few days. This system will produce some wintry weather in the Four Corners states, but a lack of moisture may limit precipitation amounts. The heaviest snow is expected late tonight through Thursday in the higher elevations in northern New Mexico and southern Colorado where more than 6 inches of snow could fall. As the system emerges in the Plains Wednesday into Thursday, it will trigger widespread showers and thunderstorms from the southern Plains to the Mid/Lower Mississippi Valley. There will be a risk of severe thunderstorms in Texas, and potential storm hazards could include hail and damaging wind gusts. Isolated to scattered instances of flash flooding will also be possible from Central/North Texas to the Mid-Mississippi Valley, especially in urban and poor drainage areas and places with training/repeat convection. While the slow low impacts the south-Central U.S., a swift moving Clipper type low pressure system will swing across the Great Lakes and Northeast, bringing wintry weather to these regions. A leading cold front will sink south across the Northeast today, then the main low will dip into the northern Great Lakes tonight, swing across the northeast on Wednesday, and push offshore Wednesday night. Snow squalls will be possible as these features move across the Great Lakes and Northeast, which would create intense bursts of heavy snowfall with gusty winds, resulting in low visibility and dangerous driving conditions. Moderate to locally heavy snow accumulations are expected from the Great Lakes into New England today through Wednesday. Temperatures will be below average across southern California and the Southwest under the influence of the upper low, and below average temperature are also expected across portions of the Great Lakes and Northeast after a cold front sinks south into these regions today. Sandwiched between the Southwest and Northeast corners of the nation, much of the Central and Eastern U.S. will experience well above average temperatures through Thursday. The highest anomalies will be in the north-Central U.S. where highs are forecast to be 15-25 degrees above normal, which could challenge a few daily high temperature records in the northern Plains and Upper Midwest.
