Meteorologists place a NEXT Weather Alert from 3 p.m. Friday through 10 a.m. Saturday, with the most dangerous precipitation \u2014 freezing rain and ice \u2014 expected to arrive after 3 p.m. and taper off between 6 a.m. and 10 a.m. Saturday. Local warnings include a winter storm warning for the Poconos and parts of the Lehigh Valley; the rest of the region is under a winter weather advisory. Residents are being urged to finish essential travel by midafternoon Friday to avoid overnight impacts.<\/p>\n<h2>Key Takeaways<\/h2>\n<ul>\n<li>NEXT Weather Alert in effect from 3 p.m. Friday, Dec. 26, through 10 a.m. Saturday, Dec. 27, covering the Philadelphia region.<\/li>\n<li>Primary hazard: freezing rain and ice after 3 p.m. Friday; pockets of up to 0.2 inch of ice are possible on roads and elevated surfaces.<\/li>\n<li>Snow- and sleet-accumulation guidance: 4\u20138 inches in parts of the Lehigh Valley and Poconos; 2\u20134 inches in parts of Northeast Philadelphia, Bucks, Burlington and Mercer counties; 1\u20132 inches across central suburbs and parts of South Jersey.<\/li>\n<li>Coating to 1 inch expected in southern and coastal counties such as Salem and Cumberland; Cape May and Kent counties may see mostly rain.<\/li>\n<li>Travel impacts: dangerous roads from snowpack or ice, likely airport delays\/cancellations and possible scattered power outages.<\/li>\n<li>Warnings for western Pennsylvania begin earlier (10 a.m. Friday) as the system approaches from the west.<\/li>\n<li>A follow-up storm is forecast Sunday night with rain, then another cold blast next week for the final week of 2025.<\/li>\n<\/ul>\n<h2>Background<\/h2>\n<p>The December 26, 2025 system is part of a larger late-December storm track that has been producing mixed precipitation across the Mid-Atlantic. Temperature profiles ahead of the system favor a transition from snow to sleet and freezing rain in many locations, a common setup when a warm layer aloft overruns cold surface air. The region\u2019s recent cold spell has left surfaces below freezing, increasing the risk that even modest freezing-rain amounts will create slick conditions on untreated roads, bridges and sidewalks.<\/p>\n<p>Forecasters issued a winter storm warning for higher terrain in the Poconos and parts of the Lehigh Valley because those areas are expected to remain cold enough for heavier, all-snow totals. A winter weather advisory covers most of the Philadelphia area and adjacent counties in Pennsylvania, New Jersey, Delaware and parts of New York and West Virginia where mixed precipitation is likely. Local transportation agencies and airports typically elevate staffing and salt\/sand operations when these advisories are issued, but timing\u2014especially an afternoon onset\u2014reduces the window for pre-treatment effectiveness on untreated secondary roads.<\/p>\n<h2>Main Event<\/h2>\n<p>The precipitation will begin across parts of the region Friday afternoon, with most locations seeing the transition to mixed precipitation after 3 p.m. The most dangerous period is Friday evening into the overnight hours, when freezing rain can accumulate on roads and power lines. Meteorologists expect the system to weaken and exit by Saturday morning, with most areas coming out of the advisory between 6 a.m. and 10 a.m., though the exact end time will depend on the track and thermal structure of the storm.<\/p>\n<p>Where the colder column holds through the event \u2014 generally north and west of a Lehigh Valley to northern New Jersey line \u2014 accumulations of 4\u20138 inches of mostly snow remain possible, especially in the Poconos. The Philadelphia core, I-95 corridor and nearby suburbs are forecast to receive 1\u20132 inches of mixed snow and sleet with up to 0.2 inch of freezing rain in spots; coastal South Jersey and Delaware coastal counties lean toward a rain or wet-snow outcome. Airport operations are likely to see delays and some cancellations as ground crews contend with mixed precipitation and icing risk.<\/p>\n<p>Local officials are advising residents to complete necessary travel before 3 p.m. Friday when possible and to prepare for slower commutes if travel is unavoidable. Utility companies have pre-positioned crews in lower-risk areas, but scattered outages remain possible if freezing rain accumulates on distribution lines and tree limbs.<\/p>\n<h2>Analysis &#038; Implications<\/h2>\n<p>Mixed-precipitation events are disproportionately disruptive compared with pure snowstorms because freezing rain and sleet reduce the effectiveness of typical winter road treatments. Salt works best on wet snow; when a glaze of ice forms, mechanical clearing and de-icing chemicals have diminished immediate effect and response times lengthen. For emergency services and road crews, the late-afternoon start reduces the daylight window for pre-treatment, increasing the chance of evening commute impacts.<\/p>\n<p>Economically, the combination of airport delays, cancelled trips and slower freight movement can ripple through holiday travel and logistics: airlines and ground transport face rescheduling costs, and businesses that rely on just-in-time deliveries may see short disruptions. Power outages, even if scattered, typically affect the most vulnerable populations first\u2014seniors, those dependent on electric medical devices, and people without alternative heating options\u2014so municipal shelters and warming centers may need to be readied depending on outage scope.<\/p>\n<p>Regionally, the storm highlights the sensitivity of the Mid-Atlantic to boundary-layer thermal structure; small shifts in the storm track or the strength of the warm layer aloft could materially change where heavy snow falls versus where freezing rain dominates. That uncertainty also complicates messaging: officials must urge caution broadly without overstating impacts for neighborhoods that ultimately see only a coating or rain.<\/p>\n<h2>Comparison &#038; Data<\/h2>\n<figure>\n<table>\n<thead>\n<tr>\n<th>Area<\/th>\n<th>Expected Accumulation<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Poconos &#038; parts of Lehigh Valley<\/td>\n<td>4\u20138 inches (mostly snow)<\/td>\n<\/tr>\n<tr>\n<td>Northeast Philly, Bucks, Burlington, Mercer<\/td>\n<td>2\u20134 inches (snow and sleet)<\/td>\n<\/tr>\n<tr>\n<td>Philadelphia, I-95 corridor, Montgomery, Berks, Camden<\/td>\n<td>1\u20132 inches (snow\/sleet + up to 0.2&#8243; ice)<\/td>\n<\/tr>\n<tr>\n<td>Salem, Cumberland, southern counties<\/td>\n<td>Coating\u20131 inch (mix); some areas rain<\/td>\n<\/tr>\n<tr>\n<td>Cape May, Kent counties<\/td>\n<td>Mostly rain<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/figure>\n<p>The table groups the guidance published by local forecasters; totals include both snow and sleet where noted. If the storm track shifts a few miles south, some areas currently forecast for sleet could see more freezing rain and lower snow totals. Conversely, a track slightly north would expand the area of heavier snow. Forecast uncertainty is highest along the transition zone between all-snow and mixed precipitation.<\/p>\n<h2>Reactions &#038; Quotes<\/h2>\n<p>Local media and officials have already issued advisories to the public and travelers.

When that supercooled liquid strikes cold ground or objects it freezes on contact, creating glaze ice. Sleet forms when that refreezing happens before the precipitation reaches the ground, producing small ice pellets. The vertical temperature profile determines which precipitation type dominates and small changes aloft can flip outcomes across short distances.<\/p>\n<\/details>\n<\/aside>\n<h2>Unconfirmed<\/h2>\n<ul>\n<li>The exact storm track and thermal profile could still change, which would alter final snow, sleet and ice distributions.<\/li>\n<li>Precise timing of the end of freezing rain\u2014currently forecast between 6 and 10 a.m. Saturday\u2014remains dependent on how quickly the colder surface air modifies.<\/li>\n<li>The scope and location of any power outages are uncertain; utilities have stated they are prepared but outage locations and durations cannot be predicted precisely before the event.<\/li>\n<\/ul>\n<h2>Bottom Line<\/h2>\n<p>This December 26 system combines snow, sleet and freezing rain and will most likely make evening and overnight travel hazardous across greater Philadelphia. The primary danger is ice accumulation on roads and infrastructure after 3 p.m. Friday, with the highest snow totals north in the Lehigh Valley and Poconos and mixed precipitation along and south of I-95.<\/p>\n<p>Residents should complete essential travel by midafternoon Friday when feasible, prepare for slower commutes and check airlines, transit providers and county road agencies for updates. Monitor forecasts and public-safety bulletins overnight; small shifts in the storm track could materially change impacts for specific communities.<\/p>\n<h2>Sources<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.cbsnews.com\/philadelphia\/news\/snow-ice-weather-philadelphia-dec-26\/\" target=\"_blank\" rel=\"noopener\">CBS News Philadelphia<\/a> \u2014 local news report and forecast summary (original reporting\/aggregation).<\/li>\n<li><a href=\"https:\/\/www.weather.gov\/\" target=\"_blank\" rel=\"noopener\">National Weather Service<\/a> \u2014 official forecast products and warnings (government\/official).<\/li>\n<\/ul>\n<\/article>\n","protected":false},"excerpt":{"rendered":"<p>Lead: A powerful winter system will move into the Philadelphia metropolitan area Friday, bringing snow, sleet and freezing rain that will create hazardous travel from the afternoon into Saturday morning.
