Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 339am EDT Thu Mar 27 2025 Synopsis High pressure will drift offshore through tonight as a warm front approaches from the Ohio River Valley. The warm front will lift across the Mid-Atlantic Friday, then linger near the area this weekend. Low pressure will move across the Great Lakes Sunday into Monday dragging a cold front across the region. High pressure will follow for Tuesday into Wednesday, then another frontal system will approach Wednesday into Thursday. Near Term - Through Tonight Early morning surface observations reveal a weak pressure trough arcing from near Petersburg WV to southern MD which had drifted southwest yesterday evening. Behind/to the northeast of this boundary were slightly higher dew points and light NE flow. The boundary was largely dissipating as boundary layer winds decouple, washing out any signal of a wind shift or dew point gradient. Aloft, a vort max was lifting atop this remnant low- level boundary resulting in very weak overrunning, a few clouds, and perhaps a sprinkle near the Alleghenies. After daybreak, the aforementioned vort max should lift away. Low levels will be abundantly dry with very little in the way of cloud cover as west to northwest wind gusts pick up to 15-25 mph. The downsloping wind on the north side of high pressure centered over the Carolinas should push temps well into the 50s and 60s for the lower elevations (40s mountains), so have leaned on the warmer side of guidance. Seasonable temperatures and increasing clouds are expected tonight as winds turn southerly ahead of an approaching warm front. Little to no precipitation is expected prior to daybreak Friday with low temps in the 30s to lower 40s. Short Term - Friday Through Saturday Night A warm front will lift across the Mid-Atlantic on Friday. Dry low levels ahead of the front may keep rain shower coverage more scattered in nature. Despite the increased cloud cover and some showers around, southwest flow should push temps well into the 60s, with lower 70s most likely in central VA where more breaks in the clouds are likely. The steady south/southwest flow and lingering clouds will keep temps mild Friday night, mainly in the 50s. The warm front will linger near or just north of the area Saturday. In its wake, clouds will linger, but west to southwest downsloping flow still looks to push temps into the 70s, perhaps near 80 in spots. Saturday night looks to be another mild night with lingering clouds and west to southwest winds, perhaps not falling below 60 in parts of the area through early Sunday morning. Rain chances may increase late at night west of I-81. Long Term - Sunday Through Wednesday A series of disturbances will ride up over a ridge of high pressure to the southeast and bring rain showers to the region on Sunday into Sunday evening. There could be a few thunderstorms as well. There is a better chance for these showers over the mountains as the track of these disturbances will be just to the northwest of our northwest zones. Highs should reach the 70s widespread Sunday. The threat for rain showers shifts to the eastern shore of Maryland Sunday night into early Monday. Widespread showers and thunderstorms return midday Monday through Monday evening as a strong cold front pushes across the region. High temperatures should be in the 70s. By Monday night, the shower and thunderstorm threat diminishes and temperatures drop to cooler readings. Temperatures are expected to fall through the 60s and 50s and bottom out in the 40s in many places. High pressure will build into the region Tuesday, then slide to the east Tuesday night. Dry conditions and colder temperatures are expected Tuesday into Tuesday night. A developing warm front will develop Tuesday night to our south and will begin to track northward into and across our region by Wednesday. Limited moisture return up and over the warm front will result in limited rainfall or none. Marine Light winds early this morning out of the west will increase by late morning. Gusts to around 20 knots are expected, mainly over the near shore waters where mixing will be more efficient from late morning through mid to late afternoon. As winds turn south tonight, gusts around 20 knots are expected over the middle portion of the Chesapeake Bay and lower tidal Potomac River. West to southwest flow will prevail Friday into Saturday as a warm front lifts across the waters. Near shore gusts may approach 20 knots or perhaps a little higher during the afternoon hours each day, but cold water relative to warming air temps probably keeps mixing and gusts lower over the wider and deeper waterways. Otherwise, a few showers are possible Friday. Small Craft Advisories possible Sunday through Monday night. Winds southwest 10 to 15 knots gusts up to 20 knots Sunday and Sunday night. Winds southwest shifting northwest 10 to 15 knots gusts 20 knots Monday and Monday night. Fire Weather Near critical fire weather conditions may develop this afternoon as relative humidity values fall into the teens and 20s. Winds will be lighter, but may still gust to around 20 mph particularly over the higher elevations and north of Highway 50. 10-hour fuel moisture may hover around 10 percent, but finer fuels will continue to rapidly dry out. Additionally, very little cloud cover is expected for most of the day. RH recoveries may be modest tonight, only rising into the 50s and 60s (perhaps slightly higher near the Chesapeake Bay and over the Alleghenies). A warm front will lift into the area Friday bringing more clouds and the potential for rain showers. NOAA Baltimore MD/Washington DC Office: Watches - Warnings - Advisories DC...None. MD...None.
