965 FXUS01 KWBC 011950 PMDSPD Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 248 PM EST Sun Mar 01 2026 Valid 00Z Mon Mar 02 2026 - 00Z Wed Mar 04 2026 ...A lifting frontal boundary will bring a swath of precipitation from the central to eastern U.S. the next couple of days as a wintry mix to the north gradually transitions to more widespread shower and thunderstorm chances... ...Lower elevation showers and thunderstorms and higher elevation snow expected from the Paciifc Northwest to the central Rockies through Monday... ...Record warmth across the Southwest to southern Plains continues while Arctic air filters southward across the northern tier behind a strong cold front... Energetic upper-flow over a wavy frontal boundary will lead to widespread precipitation chances from the central to eastern U.S. over the next few days. Showers and some thunderstorms are expected to focus along the boundary while a wintry mix is expected to the north as warm moist air overruns colder air at the surface. For the rest of Sunday, showers and storms will focus from portions of the southern Plains into the Ozarks and Mid-South while a mix of some freezing rain and snow is expected through the Lower Missouri Valley tonight. Precipitation chances will shift eastward through the overnight hours and into the day Monday from the Middle Missouri Valley into the Ohio Valley and central Appalachians, with rain once again for locations further south and a wintry mix more likely to the north. By Monday evening, a greater surge of warm, moist air will lead to another round of precipitation as the front begins to lift northward. The potentially most impactful precipitation will be across portions of the central Appalachians and Mid-Atlantic late Monday into Tuesday morning where freezing rain is expected on the northern side of the front. Some ice accretions are forecast, especially along the eastern side of the central Appalachians. This wintry mix will lift northward into New England through the day Tuesday, with some light ice accretions and snow accumulations possible. Widespread showers and thunderstorms are also expected into the day Tuesday along the lifting front from the central Plains eastward through the Midwest and into the Mid-Atlantic as areas previously seeing wintry precipitation transition to all rain. Some more moderate to locally heavy rain will be possible particularly from the Middle Missouri Valley east into the northern Ohio Valley and nearing the Great Lakes into Tuesday night, with an isolated minor flood risk. An upper-trough moving into the western U.S. will continue to lead to lower elevation showers and thunderstorms from northern California and the southern Pacific Northwest east into the Great Basin today and into Monday. Precipitation chances will gradually decrease from west to east throughout the day Monday with most areas clearing out by Tuesday morning. Some light to moderate snow is also expected for the higher elevations of the regional mountain ranges of the Great Basin as well as into portions of the northern/central Rockies. Another system will approach the Pacific Northwest on Tuesday with increasing chances for lower elevation/coastal rain and higher elevation snow. Elsewhere, daily thunderstorms are forecast for South Florida as a weakening frontal boundary lingers nearby. Record-breaking warmth has kicked off the month of March and meteorological spring across the Southwest today as well above average high temperatures soar into the mid-90s, with highs into the 80s reaching into the southern Plains and lower Mississippi Valley. While the summer-like warmth wanes across the Southwest early this week, above average temperatures are expected to become more widespread across the Great Plains and Ohio/Mississippi Valley by Tuesday. Additionally, numerous daily record highs are forecast across the southern Plains and lower Mississippi Valley on Tuesday as high temperatures rise into the mid-to-upper 80s. Conversely, below average temperatures and arctic cold are forecast to be located north of the aforementioned cold front through Monday across the northern Plains, Upper Midwest/Great Lakes, and Northeast. Here, high temperatures are forecast to struggle to rise out of the teens during the daytime hours, with low temperatures dipping below zero for some locations. Fortunately, this arctic blast is expected to be short-lived as temperatures return to near-average values by Wednesday.
