084 FXUS01 KWBC 260757 PMDSPD Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 255 AM EST Fri Dec 26 2025 Valid 12Z Fri Dec 26 2025 - 12Z Sun Dec 28 2025 ...One more wet day today across California before conditions improve for the weekend... ...Accumulating ice from the upper Midwest to the Great Lakes and into Pennsylvania today before reaching the northern Mid-Atlantic tonight; moderate to heavy snow tonight across southern New England... ...Record warmth hangs around for the southern Plains to the Tennessee Valley... After several days of deluge from heavy rainfall, California can expect to dry out this weekend as the last of a series of energetic low pressure systems is forecast to move pass the region. In the short-term however, more bands of moderate to heavy rain ahead of this final system continues to stream into California early this morning. A slight risk of flash flooding is anticipated today across southern California, along with strong winds and some embedded thunderstorms especially near the coast. Please listen to emergency officials, stay tuned to local warnings, and have a safe holiday. In addition, more heavy snow is expected for the high terrain of the Sierra Nevada before the snow tapers off tonight. The upper Midwest will see a swath of snow and ice blossoming this morning ahead of a clipper system that is pushing against a high pressure system in eastern Canada feeding the cold air. Light to moderate snowfall is expected across the upper Great Lakes from this system while areas from lower Michigan to Pennsylvania can expect to receive up to a quarter of an inches of freezing rain today into tonight with locally higher amounts. This includes major urban areas of Baltimore and Philadelphia. For areas farther north from upstate New York to the Tri-State area including New York City and Long Island, 4-8 inches of snowfall is forecast for late Friday into Friday night. Road conditions will be treacherous for those traveling back from the holiday. See the WPC key message on the "Post-Christmas Winter Storm" for more details. By Saturday, the Mid-Atlantic and southern New England will clear out as the system races out into the Atlantic, but winds will initially be gusty before diminishing Saturday night. Meanwhile, anomalous warmth will be the rule over the mid-section of the country. High temperatures in the upper 70s to the low 80s are predicted from Texas to the Tennessee Valley today and into the weekend and as far east as the Carolinas on Saturday. Many cities could break or near record warm high temperatures each day, with some records dating as far back as the 1880s. Low temperatures will also be warm in the upper 50s to low 60s. This December soupy airmass will bring chances for fog each day along the Gulf Coast, some which may be locally dense and bring low visibility. Other weather in the country worth monitoring will be the Intermountain West as the West Coast trough and surface cold front move through this weekend. High elevation snow and gusty winds are likely in the higher elevations. Rain showers are likely in the valleys on Saturday for the area. Toward the end of the forecast period on Sunday, an outbreak of arctic air will begin to funnel down into the U.S. behind an intensifying low pressure system over the central Plains along the arctic front surging southward from Canada. By Sunday morning, temperatures near the Canadian border in the northern High Plains could dip below zero. Meanwhile, frigid wind chills under very windy conditions will be surging down toward the central Plains. Kong/Wilder Graphics available at https://www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php $$
