| Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 930am EST Thu Jan 15 2026 .WHAT HAS CHANGED... The Winter Weather Advisory for the Alleghenies is now in effect until 5pm EST with additional snow accumulations of 1 to 3 inches expected. .KEY MESSAGES... - 1) Cold and windy conditions are expected today, with mountain snow showers. - 2) Chilly conditions continue Friday, with a very slight chance for a late morning/early afternoon snow shower. - 3) Well below average temps with multiple disturbances this weekend through the middle of next week could bring dangerous wind chills and wintry weather at times. KEY MESSAGE 1...Cold and windy conditions are expected today, with mountain snow showers. As of early this morning, low pressure is centered well off to our north over Central New York, and the system's trailing cold front has cleared the forecast area. As we progress through the day, that area of low pressure will lift northeastward toward northern Maine by this evening, while the mid-upper level trough axis moves overhead. Strong cold advection is underway within west-northwesterly low-level flow. Winds are gusting to around 25-35 mph, and temperatures are dropping through the 30s and 40s. Most locations should drop to near or below freezing by daybreak. There has been a fair amount of dry air working in, which combined with the gusty winds should be able to evaporate much of the residual moisture that was leftover from light rain earlier tonight. However, a few icy spots can't be ruled out this morning if some of the residual moisture fails to evaporate and refreezes. Temperatures will hold relatively steady through the day today, as daytime heating is offset by strong cold advection aloft, with 850 hPa temperatures crashing to near -15 C. This will result in temperatures in the low to mid 30s to the east of the Blue Ridge, with 20s to the west of the Blue Ridge, and teens in the Alleghenies. West-northwesterly winds gusting to around 20-30 mph will make it feel even colder, with wind chills holding in the teens/lower 20s at lower elevations, and then single digits above/below zero in the mountains. The highest elevations in western Grant/western Pendleton Counties will have wind chills today through tonight in the negative teens. Cold Weather Advisories are in effect for those zones. Dry conditions are expected to the east of the Alleghenies today, with mostly cloudy skies for most. A few more breaks of sun are likely to develop from Central Virginia to Southern Maryland. Snow showers will continue on and off in the Alleghenies through early this evening. Winter Weather Advisories remain in effect for western Garrett, western Pendleton, and western Grant Counties. In total, 3-6 inches of snow is expected in those locations, with roughly 1-3 inches falling during the daylight hours today. Expect on and off periods of heavier upslope snow showers/squalls late this morning into this afternoon. Blowing snow could result in reduced visibilities. Dry conditions are forecast for all overnight, but it will remain cold. Overnight lows are forecast to be in the teens for most locations, with lower 20s along and southeast of I-95. KEY MESSAGE 2...Chilly conditions continue Friday, with a very slight chance for a late morning/early afternoon snow shower. By daybreak Friday, we'll find ourselves positioned between two prominent shortwaves embedded within a much broader longwave trough encompassing the bulk of the CONUS. The lead shortwave will depart further off into the Canadian Maritimes over the course of the day, while the trailing shortwave tracks eastward across the western and central Great Lakes. Locally, we'll have low- amplitude ridging in place at both the surface and aloft, while low pressure deepens well to our northwest over Lake Superior. A very subtle disturbance embedded within the flattening shortwave ridge will move through during the late morning/early afternoon hours. A couple of the 00z models (notably the GFS, FV3, and WRF-NSSL) hint at some light snow showers developing across Northern Virginia and north-central Maryland as this disturbance moves through. The HRRR (High-Resolution Rapid Refresh) also produces echoes aloft, with no measurable precipitation. This snow shower scenario appears to be an outlier at the moment, to the point where it doesn't even show up in the point and click forecast. However, it is worth noting, since temperatures will be very cold, and any snow during that time would likely accumulate, even if it's light. Most model soundings show very dry low-level air, which will be tough to overcome. For that reason, continued dry conditions appear to be the much more likely scenario. Otherwise, conditions Friday will remain chilly, with winds picking up out of the south over the course of the day. Temperatures will start out in the teens to lower 20s around daybreak, and climb into the 30s to near 40 by mid-late afternoon. KEY MESSAGE 3...Well below average temps with multiple disturbances this weekend through the middle of next week could bring dangerous wind chills and wintry weather at times. A complex upper trough will linger off to our northwest Friday night into Saturday, reorienting into more of a positive tilt over time. A shortwave embedded within that broader trough will lift northeastward from the lower Ohio Valley toward New England Friday night into Saturday. As this occurs, a period of snow appears likely in the Alleghenies, especially late Friday night/Saturday morning. A few additional inches of accumulation appear possible there during that time. To the east of the mountains, some light precipitation could also be possible, especially Saturday morning. This precipitation could fall as a mix of rain and wet snow during the morning, or rain during the afternoon, but little if any accumulation is expected. By Saturday afternoon, temperatures are expected to warm up well into the 40s to the east of the mountains. Uncertainty arises with potential system Sunday into early Monday along the east coast. Recent trends in guidance has been for this system to dig a little more with potential low formation along eastern seaboard, but lots of spread and with no blocking upstream definitely a thread the needle scenario for accumulating snow. Thereafter, frigid cold wind chills are expected with Cold Weather headlines possible each night Sunday through Wednesday in the Alleghenies and Blue Ridge, and possible some lower elevations as well. Some uncertainty with northern stream waves during this period as well, but if there is precip, it is likely snow through the middle of next week. Marine High-end SCA (Small Craft Advisory) level winds are expected within west-northwesterly flow through the day today. A few sporadic low-end Gale gusts can't be entirely ruled out early this morning. A secondary surge of winds will move over the waters in westerly flow tonight. Low-end Gale gusts appear likely over the wider waters during the first half of the night. Earlier Gale Watches have been upgraded to Gale Warnings for all waters tonight, with the exception of the Upper Tidal Potomac, where high-end SCA (Small Craft Advisory) conditions are expected. Winds will start to decrease late tonight, before shifting out of the southwest Friday morning, and then south Friday afternoon. SCAs (Small Craft Advisories) appear possible within southerly flow later Friday afternoon into Friday night. SCAs (Small Craft Advisories) are possible in southerly flow Saturday. A cold front will move through late Saturday, and additional advisories may be needed in westerly flow Sunday into early next week.
