Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 300 PM EST Fri Mar 07 2025 Valid 00Z Sat Mar 08 2025 - 00Z Mon Mar 10 2025 ...Heavy Snow Friday night into Saturday from the Four Corners to the southern Rockies and nearby High Plains... ...Chilly airmass spreads into Southern Plains but very mild across the northern tier and the Southeast... ...Critical Fire Weather across parts of the southern High Plains into southwestern Texas... A deep low pressures system is taking its time departing into southeastern Canada while delivering additional light to moderate snow across northern Maine into early this evening. Even though the deep storm will begin to move away from New England tonight, its expansive circulation will continue to usher cold air into the Northeast under blustery northwesterly winds through much of the weekend. Some light snow could reach the higher-elevations of New England such as the Green and White Mountains this weekend. Periods of lake-effect snow can also be expected downwind of the lower Great Lakes and Adirondacks especially during the passage of a reinforcing cold front tonight. Meanwhile, a clipper low pressure system will move swiftly across the Ohio Valley through tonight before dissipating as it attempts to cross over the Appalachians into the Mid-Atlantic Saturday morning. A swath of mixed rain and snow is forecast from the Midwest to Ohio Valley through tonight, lingering a bit longer into Saturday afternoon along the western slope of the central Appalachians. Still a third low pressure system is forecast to develop over Texas tonight and then track eastward near or just inland from the Gulf Coast through the weekend. The system will bring heavy snow across the higher-elevations of Arizona tonight, across the southern Rockies into the nearby High Plains on Saturday. In addition, this system will bring a period of rain, heavy at times, along with embedded thunderstorms from west to east from eastern Texas through the Gulf Coast states through this weekend, with localized flooding issues possible for the eastern Gulf Coast. By Saturday night into Sunday, moisture from the next Pacific system will be spreading low-elevation rain and mountain snow into the western half of the Pacific Northwest. Behind the third low pressure system, much colder than normal conditions will overspread the southern Plains this weekend. Meanwhile, very mild temperatures for March will expand across the northern tier states behind a warm front. In contrast, mild conditions across the Southeast will shrink this weekend as the third low approaches from the west. Across the southern High Plains into southwestern Texas, very dry and gusty conditions behind the low will support critical fire danger into this weekend, where Red Flag/High Wind Warnings and Wind Advisories are in effect.
