Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 256 AM EST Tue Feb 25 2025 Valid 12Z Tue Feb 25 2025 - 12Z Thu Feb 27 2025 ...Locally heavy rainfall and high elevation mountain snow in the Northwest continues through the day Tuesday before winding down overnight... ...Clipper system to bring scattered rain and snow showers from the Midwest to the Appalachians/Interior Northeast late Tuesday into Wednesday... ...Well above average temperatures and mild conditions for most of the country this week... Areas of locally heavy rainfall and higher elevation mountain snow continue Tuesday across the Pacific Northwest east through the northern Rockies as an Atmospheric River event begins to wind down. A cold front passage through the region will bring an end to the precipitation with most rainfall ending by Tuesday evening and high elevation snows lingering into Wednesday morning. Rainfall totals will be down compared to the past couple of days, but some heavier additional snow accumulations are expected for the northern Cascades and ranges of the northern Rockies. An upper-level shortwave passing over the Appalachians and the interior Northeast today will bring some scattered light rain showers, with a wintry mix/snow showers for higher elevations and northern areas along the Canadian border. Little to no snow accumulations are expected. Then, a quick moving clipper system will pass through the Midwest overnight Tuesday and reach the Northeast by Wednesday bringing more scattered rain showers as well as more snow showers for northern locations near the Canadian border and higher elevations of the interior Northeast. Any snow accumulations should once again remain limited. Most of the country will see a period of mild conditions through the rest of this week, with highs upwards of 10-20 degrees above average for many locations. Forecast highs Tuesday and Wednesday generally range from the 40s and 50s for the Great Basin, northern Plains, Upper Midwest, and Northeast; the 50s and 60s for the Midwest and Mid-Atlantic; the 60s and 70s for California and the Southeast; the 70s and 80s in the southern Plains; and the 80s and 90s in the Desert Southwest. One exception to the above average temperatures will be for the Northwest Tuesday where 40s and 50s expected, though temperatures here should warm on Wednesday by 5-10 degrees. After a very warm day into the 60s and 70s for the central Plains Tuesday, a cold front passage will bring some more seasonable temperatures in the 40s and 50s Wednesday.
